[Just Launched] Options Domination Binary Trading - [Amazing System] - True Risk Free Trades! [New for 2015]

Many brokers or services will market something called “risk free” trades in which a certain number of your first trades you can get your money back should the signals they give you prove to be of bad quality. In most cases there are many regulations that require you to keep investing a certain amount before you can withdraw your “risk free” trades. This is the sign of a bad signal provider that probably makes more money selling their signals then they do actually implementing them themselves.
In our case study of the system we won 5 out of 7 of the trades and pocketed $250 in profit which is a 25% return on a small investment. We were very impressed with these results. At that time we could have elected to withdraw our original $1,000 and essentially be playing with the $250 “on the house”. CLICK HERE TO GET YOUR RISK FREE TRADES NOW!

Using their basic system of signals we were able to accumulate over $10,000 in our account in just 30 days! These are better results then we have gotten with other binary signals costing 10 times the amount of what options domination is charging. For a simple $50 a month you get multiple daily signals, keep in mind they don’t send you 1,000’s of signals a day like most services as they are focusing on the quality of the signal and not just sending you a bunch of garbage signals like many of the other companies do.

Tech's Plan after Suppressing Wave One

I did not think we'd get here. COVID cases are in the single digits, and many cases are off-campus (https://health.gatech.edu/coronavirus/health-alerts). Test positivity rates are incredibly low (https://gatech-covid-tracker.com/). I think we can say that Georgia Tech has navigated through it's first wave of COVID cases.

How did this happen? I'm not an epidemiologist, and even Dr. Fauci himself wouldn't be able to give you a 100% correct answer, because nobody can give you a 100% correct answer - there are too many unknowns. But, we can look at a few factors.

1.) Modified herd immunity threshold. Immunity is likely a real phenomena with COVID-19. Yes, there are now 7 confirmed cases of reinfection, but immunity is not a binary thing. It is not as if every person infected with COVID will either be immune, or they will be as unprotected as the rest of us. It's likely that the majority of COVID cases will gain some sort of immunity, and some will gain no immunity. For the sake of simplicity, let's just assume everyone infected with COVID at our campus has immunity.
Georgia Tech has, in total, around 900 positive COVID cases. There are ~14,000 people on campus if you wildly extrapolate from a few surveys taken on this subreddit - if anyone could find where the actual number is, it would be helpful. Additionally, around 5-10% of the US was probably infected in the original Feb-March surge, which would be 700-1400 people. This brings us to 1600-2300 immune people in a population of 14000.
The herd immunity threshold is given by (1-1/R0). Uncontrolled, the R0 for SARS-CoV2 is ~4. This means roughly 75% of the populace must be infected to gain "true immunity" - IE, you can do whatever you want, no distancing, no masking, etc. Obviously this is a bad idea. But, we aren't letting SARS-Cov2 spread uncontrollably. Mask compliance is high, people are trying to distance, people are washing their hands more often, etc. R0 is a function of environmental parameters as well - increasing distancing and hygiene decrease your R0. So what is the R0 with distancing and masking? That's a big question, but estimates from New York and Western Europe say it was somewhere around 0.8-1.1. A college campus will have a higher R0 than a typical state or nation, so we'll shift this up to 1.1-1.3.

This brings our herd immunity threshold to anywhere between 9-23%. We currently have in the range of 11.5%-16%, and some cases on campus may have gone totally undetected. Here's a twitter thread by an MIT data scientist if you want to read more about the "modified herd immunity" phenomena.

2.) The people who took the most risks have already gotten COVID. Anecdotally, and logically, this makes sense. People going to bars, frat parties, etc have already been infected, and that was our "first wave". Unfortunately, I don't know how to quantify this in any meaningful way, but it is probably a factor.

3.) Behavior change. People could've seen the surge in cases and decided to be more careful - get tested weekly, avoid indoor dining, go to the CRC early in the morning when it's less crowded rather than in the middle of the day, etc. This would lower R0 as well and aid with point 1, although again, I don't know how to meaningfully quantify this. But it is a possible factor.

____________________________________________________________________________________________________________
If you made it through the above, congratulations.

The question now is what Tech should do. Frankly, I feel like I am wasting both money and time this semester. This is unavoidable, and not Tech's fault or USG's fault - just a virus doing it's thing. But, just as governments - those of New York, China, South Korea, Germany, etc - gradually eased back on restrictions as the first curve was crushed, I believe Tech can and should do the same. We should not throw the floodgates open and let all hell break loose - but I think we can slowly loosen the screws in a manner that improves educational experiences, and in a way that avoids a second wave. Remote learning sucks. At least for intro classes, there is far better free material on Coursera - made by people who know how to deliver content online and who have been doing it for years - as opposed to professors who were thrown into this a few months ago.

As we all know, many "hybrid" courses are pretty much all online. I'd suggest the OPTION - for both professors and students, mandates are a god awful idea - to have more in-person hybrid sections. This won't give me my money's worth - but it'll give us something. As of now, I have three hybrid classes - and yet have not had a single in person class. These classes can be conducted in a safe, distanced/masked manner, as to keep our R0 low and keep reaping the rewards of the "modified herd immunity" discussed above. This might be difficult to implement in the middle of this semester, but I think it can be implemented next semester, in the absence of mass vaccination until (in the most optimistic case) February-March.

Other things include opening up lounges in dorms. Also, I know visiting other dorms is technically banned, but everyone I know is ignoring that rule. Many people aren't even aware of that rule - might as well just get rid of it if compliance is close to nil. But, I'd prefer more in-person classes above all else.

This was a long post. Ultimately, COVID is a game of trades - we could lock everyone in their homes until there's a vaccine, but that would destroy our society. We could let everyone run wild until there's a vaccine - again, that would destroy our society. It's a multivariate optimization problem, where we are trying to maximize safety, education, and the student experience. I'm just a dude trying to help us find that maximum.

TLDR: COVID-19 first wave beaten due to number of factors. More in-person classes would be nice.

Rank 18 Challenger Mech One Trick Guide 10.16

Edit - Its been a few days since I posted so I wont be checking in to answer new questions here. If you have any questions feel free to reach out to be through my stream. This guide should still be relevant to patch 10.17 but I'd recommend QuickSilver > GA due to Titans resolve nerfs.
Hello, I'm Atornyo and I first hit challenger in NA as a mech one-trick last patch and achieved as high as rank 18 in patch 10.16. I really enjoy mech as I mostly played reroll mech to hit diamond last set and think it is the most interesting composition in the game. I will be referring to mech pilots with a focus on Viktor carry as Viktor Mech.
My lolchess: https://lolchess.gg/profile/na/atornyo
Ideal Viktor Mech Level 8: https://lolchess.gg/buildeset3.5?deck=f6e3df00de7c11ea85825783e5dd3235 (legendaries can replace units with similar traits if you find a 2 star version of them or find a legendary before 2 starring the unit they replace: Lulu>Cass gp 1star > ziggs if you have an extra defensive item to give gp Ekko>shaco)
Level 9:https://lolchess.gg/buildeset3.5?deck=1c8af8c0de7d11ea8f93e91782b06499
Items that can be used in Mech Viktor:
For the Mech -
Titan’s Resolve - If your mech has one of Hand of Justice or Guardian Angel or both I recommend building this item, without either of these items you won’t see much value from Titan’s Resolve until you have a level 5 or 6 mech which means you have 2 star annie rumble and fizz. This item has the potential to be the single strongest item that your mech can use and is worth playing for every game. The downside to this item is that there is zero value in slamming the item early game as it will never hit 50 stacks until you have a mech online. The only time you are looking to potentially not have this item on your mech is if there are many people contesting (a 4+ mech lobby) the reason for this is because this item greatly increases in value the higher level your mech is. Once it hits 50 stacks your mech will 1v9 especially when coupled with a Hand of Justice or Guardian Angel.
Hand of Justice - This item is so good worth slamming every game as it works well on early game carries and is really solid on mech.
Guardian Angel - Solid item but ONLY place this on your mech if you are certain there will be a Hand of Justice or a Titan’s Resolve with it. Works well with Titan’s because your mech doesn’t lose its Titan’s stacks after its first death and can slap around the enemy team after reviving. Works well with Hand of Justice as it can heal a significant amount of HP post mortem. This item also works really well with rumble as he will oftentimes cast after coming out of the mech and his spell doesn’t go away while reviving.
Quicksilver - This item is BiS for mech IF you are unable to complete the trifecta mentioned above. In lobbies with many zephyrs this item can result in insane value, however, with optimal scouting you can sacrifice Ziggs and Cass to the Zephyr gods. The reason I believe this item isn’t as godly as many others make it out to be is the fact that it does absolutely nothing in a number of matchups other than provide 20% dodge. The problem with this item is that it is NOT slammable until you have a mech online.
Bramble Vest - One of the strongest items to slam early game. If you take an armor off the starting carousel and are blessed enough to find another by 2-1 you are building this item.
TrapClaw - This item is mostly just a 20% dodge stat boost. This item isn’t very slammable early personally, only build if I feel I don’t have any other options.
Shroud of Stillness - This item is a 20% dodge stat boost that can turn a fight with optimal positioning. If you build this item you need to scout EVERY round. Relatively slammable early but not on the same tier as bramble.
ZZ’rot - You are building this item because you want to win streak early. Neat thing with this item is that you get two voidlings over the course of the fight.
Warmog’s Armor - Probably the single strongest early game item in the game, give a protector this item and go afk until stage 4.
Ionic Spark - Another very slamable item, if you have a rod and a cloak at any point before krugs it is worth slamming as this item will save you infinite HP.
Thieve’s Gloves - This item is a bait on mech. In the past I would play Thief’s Gloves mech as a transition unit while I pivot to a non mech composition. Nowadays I only play mech so don’t recommend giving the mech this item. Not a bad shaco item and once you replace shaco with Ekko he loves it.
Itemizing Viktor - Viktor wants a morellonomicon in order to nuke the enemy team’s healing potential along with blue buff or Spear of shojin as viktor should be able to kill the backline in 2-3 spells.
If you're considering playing mech here is what you should look to do in each stage:
Stage 1: look to grab Armor>Tear>Crit Glove on first carousel units holding these specific items such as armor Malphite/Illaoi or tear Ziggs can be free tickets to winstreaking early. After carousel I try to hold brawlers rebels and infiltrators as I believe it is the strongest opener for mech, however if it is clear that a stronger board is available, such as a 2 star poppy or jarvan while you only have 1 star Illaoi/Malphite, it is worth pivoting to that. On the round that Kayn appears (1-4) I will prelevel which means I buy experience in order to achieve a level 4 shop on 2-1. This is very important as a unit like rumble/shaco/neeko with a belt can win streak the entirety of stage 2. I try to hold on to any Annie I find as I like to hold one whenever possible but it is worth selling her in order to pick up any brawlerebel/infiltrator or to ensure that you can pre level.
Stage 2: I attempt to win streak through stage 2 every single game, Viktor Mech and Mech infiltrators are not very item dependent and you can switch between the two depending on what items the game gives you. If you have any of Bramble Vest, Hand of Justice, Guardian Angel, Ionic Spark, Warmogs,blue buff, morellonomicon, or ZZ'rot Portal it is best to slam the item as the Mech can hold any of those items other than bluebuff and morellonomicon and those last 2 items are vital for viktor, Illaoi is a great holder for Mech items and Ziggs/ahri are great holders for Viktor items. On 2-1 play whatever your strongest board is as with any non-hyperroll compositions. On 2-3 before the stage 2 carousel I will prelevel in order to get a level 5 shop on 2-5 post carousel, this is extremely strong for Mech Pilot compositions as it gives you the opportunity to hit a full Mech on stage 2 or other strong early game units like rumble gnar wukong and fizz. In the case that you are on a 2 or 3 loss streak after the stage 2 carousel it is best to attempt a full loss streak in order to maximize early gold, this is the ONLY time that I would ever consider attempting to lose a round. If you are running infiltrators in your early game composition it is extra important to scout EVERY round as the difference between an infiltrator hitting a Ziggs or a 2 star frontliner is winning or losing a fight.
Stage 3: This is where a lot of decision making enters the game. If I am winstreaking with a streak of 3 or greater and I will have more than 10 gold after leveling I will level on 3-1. otherwise I will level on 3-2. If I have fizz and rumble by 3-2 and am level 6 I am willing to roll down to 10gold in order to hit an annie. If you roll down this early into the game it is vital that you do not tunnel only on units that go in your final composition, you are not rolling solely to hit a Mech you are rolling to maintain win streak this means that you will look to complete any pairs or to add unit upgrades to your current board. If you roll down and do not upgrade your board at all you will be in a very bad place so it is important to keep a very open mind on what can be thrown in to improve your composition. If I don't roll down on 3-2 I usually do not roll at all unless I am taking a large amount of damage every round in which case it can be a good idea to level to 7 post stage 3 carousel (3-5) and roll some gold to stabilize. If you are rolling it is important to not roll below 10 in stage 3 unless you have a great reason to, such as winstreaking and holding 4-6 pairs while knowing there are opponents that can beat you if you don't hit those upgrades.
What to do if you hit early Mech: Mech in stage 3 can be played in many different ways. Most of the time you will sell your frontline and be looking to play Mech + whatever your strongest backliners are which are usually the level 2 units you already had. Ideally you want to have a ziggs and infiltrator or be running 4 sorcs + Mech but it is not vital in stage 3.
Stage 4: This is where the decision between Viktor Mech and Mech infiltrators is made. If you are bleeding out and approaching death <40hp 4-1 it is worth leveling to 7 and rolling down to stabilize. Which means you are playing the level 8 board minus ziggs if by some miracle you hit aurelion sol feel free to play zed/ziggs/asol instead of the mystic units. However, in the majority of games you will level to 8 on 4-3 and roll for your board.
The 4-3 rolldown (Viktor Mech) - While rolling you are looking to hit this board https://lolchess.gg/buildeset3.5?deck=f6e3df00de7c11ea85825783e5dd3235 it is discussed earlier when to replace units with legendaries. Also I value cass and Karma over Soraka as before the mech dies other units tend to take very little to 0 damage. If you run into a GP Mercenary upgrade in this roll down it is only worth purchasing double strike as they are so expensive. You can stop rolling once you hit the units in the composition and have a level 6 mech (2 star annie rumble and fizz), a 2 star legendary or 2 star Viktor. If you hit any of those requirements with more than 20 gold and are somewhat healthy you can usually go to level 9 later in the game in order to increase your chances at first place. If you hit a 2 star asol and do not have blue buff Asol can replace Viktor at levels 8 and 9.
If you hit it is very likely that you will win streak through stage 4 and into stage 5.
Stage 5: If you rolled down at level 7 on 4-1 you are leveling to 8 and rolling on 5-1 in a last ditch effort to survive. This rolldown is the same as the standard 4-3 one. If you were able to stop rolling early and have hoarded a large amount of gold, look to go level 9. Only go level 9 if you have at least 30 gold to roll or have more than 15 gold and already hold 1 or more legendary pairs. If you are about to die feel free to roll on 8 in order to complete vital 2 stars which are any mech pilot unit +viktor and shaco. The winconditions for Mech Viktor are good mech items +perfect item 2 star Viktor or Level 9 with 2 star legendaries. The optimal level 9 composition looks like this https://lolchess.gg/buildeset3.5?deck=1c8af8c0de7d11ea8f93e91782b06499 with the option to replace Viktor with urgot 2 and giving the bluebuff to urgot and the morellos to Asol. While it is situational it is almost always better to run a 2 star unit over a 1 star legendary. In the case that you were fortunate enough to find an infiltrator spatula play it on either viktor or gangplank and instead of running Asol play 4 infiltrator level 9: https://lolchess.gg/buildeset3.5?deck=7aa7b960de8511ea9ce08d2f4408daad
If you hit either of these level 9 boards with 2 star units it is a 1st unless an opponent has a 3 star 4 cost unit or out positions you really badly.
General advice when playing Mech Viktor:
Differences between Galaxies
Dwarf Planet - Mech is so busted on this galaxy, I have seen Mech compositions hold hands 1-5 multiple times in challenger elo games. Look for titans resolve as if it procs your Mech will hit the backline. Infiltrators are weaker on this map so keep that in mind when building early game boards. Gangplank is also OMEGABUSTED on this galaxy.
Neekoverse - I just wanted to thank riot for removing this Galaxy
Superdense - I tend to run 4 infiltrator instead of ziggs at level 8. Also if winstreaking you might roll more in stage 3 as any round you win it is likely you're doing an extra 2 damage which puts a lot of pressure on a lobby.
Trade Sector - Greatly dislike this galaxy for Mech but never miss the chance to level if you can afford it while winstreaking. Going level 7 right after stage 3 carousel can be the difference between hitting an early legendary or hitting important mech units.
Treasure Trove - Not a great galaxy for Mech as you have 4 units in your composition that do not benefit greatly from items (Mystic units and annie/fizz) Also Mech doesn't benefit too greatly by having perfect items so the benefit that other compositions get is much greater.
Galactic Armory - Great for pushing early winstreaks. Always look to slam 2 full items before any pvp rounds even begin.
Binary Star - Look to take glove or tear on the first carousel. NEED to win streak as mech isn't as strong later in the game. Not as bad for mech as people make it seem but you usually need 2 dodge items (QSS, HOJ, Trapclaw, and shroud of stillness) in order to make your mech survive versus the 4 cyber players in the lobby. Need perfect Viktor items as another issue mech has in this galaxy is the fact that mystic units along with other mech units can't utilize items well.
Plunder Planet - Always push levels and try to bully other players around. Anytime you can prevent another player from killing any of your units you are denying them 2-3 gold which is a huge early game. Most of the time you will level to 8 on 4-1 and be 9 in late stage 4 or early stage 5. Can also decide to roll down on 3-5 after stage 5 carousel at level 7 in order to get as much gold as possible off the galaxy and prevent other players from killing units. Everyone spikes really hard in stage 4 on this galaxy.
Salvage world - I'm still unsure of this galaxy, I have only played 5 games on this galaxy but in 2 of them I opened with a redbuff ludens lucian with blaster buff that felt really strong. Not as important to run an early game composition that can utilize mech items well.
I'm sure I missed some stuff within this guide and will try to answer any questions in the comments over the next few days.

Binary Options Recovery: Scammed Traders, Fake Brokers, and Funds Recovery

Binary Options Recovery: Scammed Traders, Fake Brokers, and Funds Recovery
Following the “permanent temporary” measures against binary options and CFDs (contract for difference), the body in charge implements its own set of limitations that simply forbids regulated houses to offer such product in the UK, hence increasing the risk of pushing retails traders towards illegal brokers and outright scams. Fortunately, a new solution is now available to UK traders via a new United Kingdom Financial regulatory ruling.
More scrutiny from UK banks about financial transactions, even to binary optionsIn short, banks will have to take more responsibility about the financial transactions they facilitate. This new ruling should lead to the creation of a new code of conduct that will help defrauded people to have their funds recovered by their bank, unless it is proven they acted recklessly.
As a popular Financial blog puts, it, “It is likely that should a bank or credit card company be either impersonated by a fraudster in order to gain money, or trick a client into depositing, and the bank allows the transfer, a client will be able to take recourse.
The broad protection should kick for many online scheme and scams, whether it is fake investment companies, fraudulent binary options brokers or those scammers who promise to help you recover your stolen funds…only to steal from you once again. On the other hands, it means the banks will be more likely to forbid transactions to legit businesses, such as reputable cryptocurrency exchanges or honest smart options platforms.
The regulating bodies and financial institutions are taking a number of measures to prevent financial fraud. Binary options trading, in particular, is being controlled with a greater degree of robustness to protect the unwary general public being drawn into a situation where they suffer financial losses. Many hundreds of people around the world are targeted each day.
![img](prwn4ha2ecf51 " ")
Frequently they are novice investors who are unfamiliar with the markets and do not recognize that the so-called trading platform and its way of working are actually bogus. The individual only realizes the extent of the fraud when eventually when the fraudsters finally decide that there is no more money to be had and shut down the account and promptly vanish without trace.
Spotting Fraudulent Binary Options Broker
Some lawyers in the financial fraud division are very familiar with the pattern of behaviour demonstrated by the fraudulent brokers and the distress caused by their dealings with inexperienced investors. There is a track of record of recovery in relation to financial fraud and has a number of strategies and tactics to compel the fraudulent broker or associated financial service providers to restore funds to those who have been deceived.
Needless to say, the fraudsters are accomplished at hiding their tracks and frequently there are myriad inter-connected limited liability companies, often some are registered in different countries, with some dormant and some active. It is hardly surprising if the complexity of the situation results in a failure to discover a single person who can be challenged and held accountable.
However, there are various channels financial fraud lawyers use when attempting to retrieve money for clients and each avenue is investigated. Whilst an individual may be alarmed and confused at the prospect of navigating through the complex structures that have been deliberately set up to confuse, Financial fraud lawyers are usually quite familiar with strategies fraudsters use, and frequently can steer a course to the recovery of some or all of the lost money.

The step of last resort, legal action, is understandably daunting for a person who often has lost significant amounts of money to the fraudulent brokers. It is fully understandable that such a situation will leave the victim decidedly risk-averse. There have been experiences with class actions against the fraudulent brokers and has developed links with litigation funding organizations in order to offset the risk in respect of class actions.
The lessons that can be drawn from the experiences of those individuals who have had the misfortune of losing their investments to fraudsters are to be extremely cautious. Always consider every offer or investment for at least 48 hours before making a decision, a genuine broker will understand the caution that a new investor will view a proposition.
All investments carry a risk and anything that promises a return on your initial investment seems to be significantly higher than normal it is almost certainly not to be trusted. Do not allow yourself to be hurried into a decision, it is highly unlikely that an authentic broker would try to rush you into an investment, especially if you demonstrated reluctance; their reputation would suffer by such behaviour.

Selling your Covered Call - Thoughts on How to Select Your Strike and Expiration

Congratulations! You are a bag holder of company XYZ which was thought to be the best penny stock ever. Instead of feeling sorry, you consider selling covered calls to help reduce your cost basis - and eventually get out of your bags with minimal loss or even a profit!
First - let's review the call option contract. The holder of the call option contract has the right but not the obligation to purchase 100 shares of XYZ at the strike price per share. This contract has an expiration date. We assume American style option contracts which means that the option can be exercised at any point prior to expiration. Thus, there are three parameters to the option contract - the strike price, the expiration date and the premium - which represents the price per share of the contract.
The holder of the call option contract is the person that buys the option. The writer of the contract is the seller. The buyer (or holder) pays the premium. The seller (or writer) collects the premium.
As an XYZ bag holder, the covered call may help. By writing a call contract against your XYZ shares, you can collect premium to reduce your investment cost in XYZ - reducing your average cost per share. For every 100 shares of XYZ, you can write 1 call contract. Notice that that by selling the contract, you do not control if the call is exercised - only the holder of the contract can exercise it.
There are several online descriptions about the covered call strategy. Here is an example that might be useful to review Covered Call Description
The general guidance is to select the call strike at the price in which you would be happy selling your shares. However, the context of most online resources on the covered call strategy assume that you either just purchased the shares at market value or your average cost is below the market price. In the case as a bag holder, your average cost is most likely over - if not significantly over - the current market price. This situation simply means that you have a little work to reduce your average before you are ready to have your bags called away. For example, you would not want to have your strike set at $2.50 when your average is above that value as this would guarantee a net loss. (However, if you are simply trying to rid your bags and your average is slightly above the strike, then you might consider it as the strike price).
One more abstract concept before getting to what you want to know. The following link shows the Profit/Loss Diagram for Covered Call Conceptually, the blue line shows the profit/loss value of your long stock position. The line crosses the x-axis at your average cost, i.e the break-even point for the long stock position. The green/red hockey stick is the profit (green) or loss (red) of the covered call position (100 long stock + 1 short call option). The profit has a maximum value at the strike price. This plateau is due to the fact that you only receive the agreed upon strike price per share when the call option is exercised. Below the strike, the profit decreases along the unit slope line until the value becomes negative. It is a misnomer to say that the covered call is at 'loss' since it is really the long stock that has decreased in value - but it is not loss (yet). Note that the break-even point marked in the plot is simply the reduced averaged cost from the collected premium selling the covered call.
As a bag holder, it will be a two-stage process: (1) reduce the average cost (2) get rid of bags.
Okay let's talk selecting strike and expiration. You must jointly select these two parameters. Far OTM strikes will collect less premium where the premium will increase as you move the strike closer to the share price. Shorter DTE will also collect less premium where the premium will increase as you increase the DTE.
It is easier to describe stage 2 "get rid of bags" first. Let us pretend that our hypothetical bag of 100 XYZ shares cost us $5.15/share. The current XYZ market price is $3/share - our hole is $2.15/share that we need to dig out. Finally, assume the following option chain (all hypothetical):
DTE Strike Premium Intrinsic Value Time Value
20 $2.5 $0.60 $0.50 $0.10
20 $5.0 $0.25 $0 $0.25
20 $7.5 $0.05 $0 $0.05
50 $2.5 $0.80 $0.50 $0.30
50 $5.0 $0.40 $0 $0.40
50 $7.5 $0.20 $0 $0.20
110 $2.5 $0.95 $0.50 $0.45
110 $5.0 $0.50 $0 $0.50
110 $7.5 $0.25 $0 $0.25
Purely made up the numbers, but the table illustrates the notional behavior of an option chain. The option value (premium) is the intrinsic value plus the time value. Only the $2.5 strike has intrinsic value since the share price is $3 (which is greater than $2.5). Notice that intrinsic value cannot be negative. The rest of the premium is the time value of the option which is essentially the monetary bet associated with the probability that the share price will exceed the strike at expiration.
According to the table, we could collect the most premium by selling the 110 DTE $2.5 call for $0.95. However, there is a couple problems with that option contract. We are sitting with bags at $5.15/share and receiving $0.95 will only reduce our average to $4.20/share. On expiration, if still above $2.5, then we are assigned, shares called away and we receive $2.50/share or a loss of $170 - not good.
Well, then how about the $5 strike at 110 DTE for $0.50? This reduces us to $4.65/share which is under the $5 strike so we would make a profit of $35! This is true - however 110 days is a long time to make $35. You might say that is fine you just want to get the bags gone don't care. Well maybe consider a shorter DTE - even the 20 DTE or 50 DTE would collect premium that reduces your average below $5. This would allow you to react to any stock movement that occurs in the near-term.
Consider person A sells the 110 DTE $5 call and person B sells the 50 DTE $5 call. Suppose that the XYZ stock increases to $4.95/share in 50 days then goes to $8 in the next 30 days then drops to $3 after another 30 days. This timeline goes 110 days and person A had to watch the price go up and fall back to the same spot with XYZ stock at $3/share. Granted the premium collected reduced the average but stilling hold the bags. Person B on the other hand has the call expire worthless when XYZ is at $4.95/share. A decision can be made - sell immediately, sell another $5 call or sell a $7.5 call. Suppose the $7.5 call is sold with 30 DTE collecting some premium, then - jackpot - the shares are called away when XYZ is trading at $8/share! Of course, no one can predict the future, but the shorter DTE enables more decision points.
The takeaway for the second step in the 2-stage approach is that you need to select your profit target to help guide your strike selection. In this example, are you happy with the XYZ shares called away at $5/share or do you want $7.5/share? What is your opinion on the stock price trajectory? When do you foresee decision points? This will help determine the strike/expiration that matches your thoughts. Note: studies have shown that actively managing your position results in better performance than simply waiting for expiration, so you can adjust the position if your assessment on the movement is incorrect.
Let's circle back to the first step "reduce the average cost". What if your average cost of your 100 shares of XYZ is $8/share? Clearly, all of the strikes in our example option chain above is "bad" to a certain extent since we would stand to lose a lot of money if the option contract is exercised. However, by describing the second step, we know the objective for this first step is to reduce our average such that we can profit from the strikes. How do we achieve this objective?
It is somewhat the same process as previously described, but you need to do your homework a little more diligently. What is your forecast on the stock movement? Since $7.5 is the closest strike to your average, when do you expect XYZ to rise from $3/share to $7.5/share? Without PR, you might say never. With some PR then maybe 50/50 chance - if so, then what is the outlook for PR? What do you think the chances of going to $5/share where you could collect more premium?
Suppose that a few XYZ bag holders (all with a $8/share cost) discuss there outlook of the XYZ stock price in the next 120 days:
Person 10 days 20 days 30 days 40 days 50 days 100 days 120 days
A $3 $3 $3 $3 $3 $4 $4
B $4 $4 $5 $6 $7 $12 $14
C $7 $7 $7 $7 $7 $7 $7
Person A does not seem to think much price movement will occur. This person might sell the $5 call with either 20 DTE or 50 DTE. Then upon expiration, sell another $5 call for another 20-50 DTE. Person A could keep repeating this until the average is reduced enough to move onto step-2. Of course, this approach is risky if the Person A price forecast is incorrect and the stock price goes up - which might result in assignment too soon.
Person B appears to be the most bullish of the group. This person might sell the $5 call with 20 DTE then upon expiration sell the $7.5 call. After expiration, Person B might decide to leave the shares uncovered because her homework says XYZ is going to explode and she wants to capture those gains!
Person C believes that there will be a step increase in 10 days maybe due to major PR event. This person will not have the chance to reduce the average in time to sell quickly, so first he sells a $7.5 call with 20 DTE to chip at the average. At expiration, Person C would continue to sell $7.5 calls until the average at the point where he can move onto the "get rid of bags" step.
In all causes, each person must form an opinion on the XYZ price movement. Of course, the prediction will be wrong at some level (otherwise they wouldn't be bag holders!).
The takeaway for the first step in the 2-stage approach is that you need to do your homework to better forecast the price movement to identify the correct strikes to bring down your average. The quality of the homework and the risk that you are willing to take will dedicate the speed at which you can reduce your average.
Note that if you are unfortunate to have an extremely high average per share, then you might need to consider doing the good old buy-more-shares-to-average-down. This will be the fastest way to reduce your average. If you cannot invest more money, then the approach above will still work, but it will require much more patience. Remember there is no free lunch!
Advanced note: there is another method to reduce your (high) average per share - selling cash secured puts. It is the "put version" of a cover call. Suppose that you sell a XYZ $2.5 put contract for $0.50 with 60 DTE. You collect $50 from the premium of the contract. This money is immediately in your bank and reduces your investment cost. But what did you sell? If XYZ is trading below $2.50, then you will be assigned 100 shares of XYZ at $2.50/share or $250. You own more shares, but at a price which will reduce your average further. Being cash secured, your brokerage will reserve $250 from your account when you sell the contract. In essence, you reduce your buying power by $250 and conditionally purchase the shares - you do not have them until assignment. If XYZ is greater than the strike at expiration, then your broker gives back $250 cash / buying power and you keep the premium.

Early assignment - one concern is the chance of early assignment. The American style option contract allows the holder the opportunity to exercise the contract at any time prior to expiration. Early assignment almost never occurs. There are special cases that typically deal with dividends but most penny stocks are not in the position to hand out dividends. Aside from that, the holder would be throwing away option time value by early exercise. It possibly can handle - probably won't - it actually would be a benefit when selling covered calls as you would receive your profit more quickly!


This post has probably gone too long! I will stop and let's discuss this matter. I will add follow-on material with some of the following topics which factors into this discussion:
Open to other suggestions. I'm sure there are some typos and unclear statements - I will edit as needed!

10.16 Rank 18 Challenger Mech One Trick Guide

Hey all I posted this on CompetitiveTFT yesterday and someone recommended that I post it here as well so here you go!
My stream is https://www.twitch.tv/banananationss and I’ll be streaming for a bit after posting if you would like to come and ask questions.
Hello, I'm Atornyo and I first hit challenger in NA as a mech one-trick last patch and achieved as high as rank 18 in patch 10.16. I really enjoy mech as I mostly played reroll mech to hit diamond last set and think it is the most interesting composition in the game. I will be referring to mech pilots with a focus on Viktor carry as Viktor Mech.
My lolchess: https://lolchess.gg/profile/na/atornyo
Ideal Viktor Mech Level 8: https://lolchess.gg/buildeset3.5?deck=f6e3df00de7c11ea85825783e5dd3235 (legendaries can replace units with similar traits if you find a 2 star version of them or find a legendary before 2 starring the unit they replace: Lulu>Cass gp 1star > ziggs if you have an extra defensive item to give gp Ekko>shaco)
Level 9:https://lolchess.gg/buildeset3.5?deck=1c8af8c0de7d11ea8f93e91782b06499
Items that can be used in Mech Viktor:
For the Mech -
Titan’s Resolve - If your mech has one of Hand of Justice or Guardian Angel or both I recommend building this item, without either of these items you won’t see much value from Titan’s Resolve until you have a level 5 or 6 mech which means you have 2 star annie rumble and fizz. This item has the potential to be the single strongest item that your mech can use and is worth playing for every game. The downside to this item is that there is zero value in slamming the item early game as it will never hit 50 stacks until you have a mech online. The only time you are looking to potentially not have this item on your mech is if there are many people contesting (a 4+ mech lobby) the reason for this is because this item greatly increases in value the higher level your mech is. Once it hits 50 stacks your mech will 1v9 especially when coupled with a Hand of Justice or Guardian Angel.
Hand of Justice - This item is so good worth slamming every game as it works well on early game carries and is really solid on mech.
Guardian Angel - Solid item but ONLY place this on your mech if you are certain there will be a Hand of Justice or a Titan’s Resolve with it. Works well with Titan’s because your mech doesn’t lose its Titan’s stacks after its first death and can slap around the enemy team after reviving. Works well with Hand of Justice as it can heal a significant amount of HP post mortem. This item also works really well with rumble as he will oftentimes cast after coming out of the mech and his spell doesn’t go away while reviving.
Quicksilver - This item is BiS for mech IF you are unable to complete the trifecta mentioned above. In lobbies with many zephyrs this item can result in insane value, however, with optimal scouting you can sacrifice Ziggs and Cass to the Zephyr gods. The reason I believe this item isn’t as godly as many others make it out to be is the fact that it does absolutely nothing in a number of matchups other than provide 20% dodge. The problem with this item is that it is NOT slammable until you have a mech online.
Bramble Vest - One of the strongest items to slam early game. If you take an armor off the starting carousel and are blessed enough to find another by 2-1 you are building this item.
TrapClaw - This item is mostly just a 20% dodge stat boost. This item isn’t very slammable early personally, only build if I feel I don’t have any other options.
Shroud of Stillness - This item is a 20% dodge stat boost that can turn a fight with optimal positioning. If you build this item you need to scout EVERY round. Relatively slammable early but not on the same tier as bramble.
ZZ’rot - You are building this item because you want to win streak early. Neat thing with this item is that you get two voidlings over the course of the fight.
Warmog’s Armor - Probably the single strongest early game item in the game, give a protector this item and go afk until stage 4.
Ionic Spark - Another very slamable item, if you have a rod and a cloak at any point before krugs it is worth slamming as this item will save you infinite HP.
Thieve’s Gloves - This item is a bait on mech. In the past I would play Thief’s Gloves mech as a transition unit while I pivot to a non mech composition. Nowadays I only play mech so don’t recommend giving the mech this item. Not a bad shaco item and once you replace shaco with Ekko he loves it.
Itemizing Viktor - Viktor wants a morellonomicon in order to nuke the enemy team’s healing potential along with blue buff or Spear of shojin as viktor should be able to kill the backline in 2-3 spells.
If you're considering playing mech here is what you should look to do in each stage:
Stage 1: look to grab Armor>Tear>Crit Glove on first carousel units holding these specific items such as armor Malphite/Illaoi or tear Ziggs can be free tickets to winstreaking early. After carousel I try to hold brawlers rebels and infiltrators as I believe it is the strongest opener for mech, however if it is clear that a stronger board is available, such as a 2 star poppy or jarvan while you only have 1 star Illaoi/Malphite, it is worth pivoting to that. On the round that Kayn appears (1-4) I will prelevel which means I buy experience in order to achieve a level 4 shop on 2-1. This is very important as a unit like rumble/shaco/neeko with a belt can win streak the entirety of stage 2. I try to hold on to any Annie I find as I like to hold one whenever possible but it is worth selling her in order to pick up any brawlerebel/infiltrator or to ensure that you can pre level.
Stage 2: I attempt to win streak through stage 2 every single game, Viktor Mech and Mech infiltrators are not very item dependent and you can switch between the two depending on what items the game gives you. If you have any of Bramble Vest, Hand of Justice, Guardian Angel, Ionic Spark, Warmogs,blue buff, morellonomicon, or ZZ'rot Portal it is best to slam the item as the Mech can hold any of those items other than bluebuff and morellonomicon and those last 2 items are vital for viktor, Illaoi is a great holder for Mech items and Ziggs/ahri are great holders for Viktor items. On 2-1 play whatever your strongest board is as with any non-hyperroll compositions. On 2-3 before the stage 2 carousel I will prelevel in order to get a level 5 shop on 2-5 post carousel, this is extremely strong for Mech Pilot compositions as it gives you the opportunity to hit a full Mech on stage 2 or other strong early game units like rumble gnar wukong and fizz. In the case that you are on a 2 or 3 loss streak after the stage 2 carousel it is best to attempt a full loss streak in order to maximize early gold, this is the ONLY time that I would ever consider attempting to lose a round. If you are running infiltrators in your early game composition it is extra important to scout EVERY round as the difference between an infiltrator hitting a Ziggs or a 2 star frontliner is winning or losing a fight.
Stage 3: This is where a lot of decision making enters the game. If I am winstreaking with a streak of 3 or greater and I will have more than 10 gold after leveling I will level on 3-1. otherwise I will level on 3-2. If I have fizz and rumble by 3-2 and am level 6 I am willing to roll down to 10gold in order to hit an annie. If you roll down this early into the game it is vital that you do not tunnel only on units that go in your final composition, you are not rolling solely to hit a Mech you are rolling to maintain win streak this means that you will look to complete any pairs or to add unit upgrades to your current board. If you roll down and do not upgrade your board at all you will be in a very bad place so it is important to keep a very open mind on what can be thrown in to improve your composition. If I don't roll down on 3-2 I usually do not roll at all unless I am taking a large amount of damage every round in which case it can be a good idea to level to 7 post stage 3 carousel (3-5) and roll some gold to stabilize. If you are rolling it is important to not roll below 10 in stage 3 unless you have a great reason to, such as winstreaking and holding 4-6 pairs while knowing there are opponents that can beat you if you don't hit those upgrades.
What to do if you hit early Mech: Mech in stage 3 can be played in many different ways. Most of the time you will sell your frontline and be looking to play Mech + whatever your strongest backliners are which are usually the level 2 units you already had. Ideally you want to have a ziggs and infiltrator or be running 4 sorcs + Mech but it is not vital in stage 3.
Stage 4: This is where the decision between Viktor Mech and Mech infiltrators is made. If you are bleeding out and approaching death <40hp 4-1 it is worth leveling to 7 and rolling down to stabilize. Which means you are playing the level 8 board minus ziggs if by some miracle you hit aurelion sol feel free to play zed/ziggs/asol instead of the mystic units. However, in the majority of games you will level to 8 on 4-3 and roll for your board.
The 4-3 rolldown (Viktor Mech) - While rolling you are looking to hit this board https://lolchess.gg/buildeset3.5?deck=f6e3df00de7c11ea85825783e5dd3235 it is discussed earlier when to replace units with legendaries. Also I value cass and Karma over Soraka as before the mech dies other units tend to take very little to 0 damage. If you run into a GP Mercenary upgrade in this roll down it is only worth purchasing double strike as they are so expensive. You can stop rolling once you hit the units in the composition and have a level 6 mech (2 star annie rumble and fizz), a 2 star legendary or 2 star Viktor. If you hit any of those requirements with more than 20 gold and are somewhat healthy you can usually go to level 9 later in the game in order to increase your chances at first place. If you hit a 2 star asol and do not have blue buff Asol can replace Viktor at levels 8 and 9.
If you hit it is very likely that you will win streak through stage 4 and into stage 5.
Stage 5: If you rolled down at level 7 on 4-1 you are leveling to 8 and rolling on 5-1 in a last ditch effort to survive. This rolldown is the same as the standard 4-3 one. If you were able to stop rolling early and have hoarded a large amount of gold, look to go level 9. Only go level 9 if you have at least 30 gold to roll or have more than 15 gold and already hold 1 or more legendary pairs. If you are about to die feel free to roll on 8 in order to complete vital 2 stars which are any mech pilot unit +viktor and shaco. The winconditions for Mech Viktor are good mech items +perfect item 2 star Viktor or Level 9 with 2 star legendaries. The optimal level 9 composition looks like this https://lolchess.gg/buildeset3.5?deck=1c8af8c0de7d11ea8f93e91782b06499 with the option to replace Viktor with urgot 2 and giving the bluebuff to urgot and the morellos to Asol. While it is situational it is almost always better to run a 2 star unit over a 1 star legendary. In the case that you were fortunate enough to find an infiltrator spatula play it on either viktor or gangplank and instead of running Asol play 4 infiltrator level 9: https://lolchess.gg/buildeset3.5?deck=7aa7b960de8511ea9ce08d2f4408daad
If you hit either of these level 9 boards with 2 star units it is a 1st unless an opponent has a 3 star 4 cost unit or out positions you really badly.
General advice when playing Mech Viktor:
Differences between Galaxies
Dwarf Planet - Mech is so busted on this galaxy, I have seen Mech compositions hold hands 1-5 multiple times in challenger elo games. Look for titans resolve as if it procs your Mech will hit the backline. Infiltrators are weaker on this map so keep that in mind when building early game boards. Gangplank is also OMEGABUSTED on this galaxy.
Neekoverse - I just wanted to thank riot for removing this Galaxy
Superdense - I tend to run 4 infiltrator instead of ziggs at level 8. Also if winstreaking you might roll more in stage 3 as any round you win it is likely you're doing an extra 2 damage which puts a lot of pressure on a lobby.
Trade Sector - Greatly dislike this galaxy for Mech but never miss the chance to level if you can afford it while winstreaking. Going level 7 right after stage 3 carousel can be the difference between hitting an early legendary or hitting important mech units.
Treasure Trove - Not a great galaxy for Mech as you have 4 units in your composition that do not benefit greatly from items (Mystic units and annie/fizz) Also Mech doesn't benefit too greatly by having perfect items so the benefit that other compositions get is much greater.
Galactic Armory - Great for pushing early winstreaks. Always look to slam 2 full items before any pvp rounds even begin.
Binary Star - Look to take glove or tear on the first carousel. NEED to win streak as mech isn't as strong later in the game. Not as bad for mech as people make it seem but you usually need 2 dodge items (QSS, HOJ, Trapclaw, and shroud of stillness) in order to make your mech survive versus the 4 cyber players in the lobby. Need perfect Viktor items as another issue mech has in this galaxy is the fact that mystic units along with other mech units can't utilize items well.
Plunder Planet - Always push levels and try to bully other players around. Anytime you can prevent another player from killing any of your units you are denying them 2-3 gold which is a huge early game. Most of the time you will level to 8 on 4-1 and be 9 in late stage 4 or early stage 5. Can also decide to roll down on 3-5 after stage 5 carousel at level 7 in order to get as much gold as possible off the galaxy and prevent other players from killing units. Everyone spikes really hard in stage 4 on this galaxy.
Salvage world - I'm still unsure of this galaxy, I have only played 5 games on this galaxy but in 2 of them I opened with a redbuff ludens lucian with blaster buff that felt really strong. Not as important to run an early game composition that can utilize mech items well.
I'm sure I missed some stuff within this guide and will try to answer any questions in the comments over the next few days.

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

Peri-areolar top surgery with Dr. Fischer - the pre-op report

Hi everyone – this is a follow-up to a post I made about a month ago, asking if anyone would be interested in the details of my then-upcoming top surgery. I’m officially post-op now (five days!) and working on a ridiculously detailed writeup. This is the first part, which goes right up until the surgery itself. I’m going to wait a few more days to do the post-op one so that I can go up to the process of getting the drains out. Feel free to skip to the end to get to the salient info, and to comment with any questions about stuff I might have left out!
So, without further ado, how I got here:
First the basics. I'm 31 years old. I live in Maryland. I'm five feet tall and weigh around ninety pounds, give or take a couple in either direction. My chest measurement before surgery was about 28 inches, and about 26 "underbust." I've never been on testosterone or puberty blockers. I've never really had to wear a binder, and avoided it because I knew that I had to be gentle with that tissue if I wanted the results that I'd really hoped were possible. Keep this in mind - I'm hardly an average representation of anything, so my experience is most likely atypical in a lot of ways. But I'm hoping the overall information could be helpful.
I came out when I was 25, though I'd known since high school. Top surgery was on my radar, but trans stuff was on the fringe then - I read a lot of "butch lesbian who got top surgery" blogs, which was the only thing that made it seem possible for me, though the thought of paying for it (I was overestimating the cost by almost double, and too scared to actually look it up) seemed unthinkable. I didn't know about anything but double incision surgery, which was pretty horrifying to me. So I put the thought out of my mind for almost ten years.
When I aged out of my parents' insurance and got my own, most plans had a line specifying that they did not cover anything meant to "alter the patient's physical sex," or something to that effect. This changed a few years ago, but at the time I didn't qualify for sick leave at work, and I was still paying off my student loans. Along the way things progressed - I started using a new name, then changed it legally, and then my state started allowing "unspecified" gender markers on driver's licenses. I paid off my loans and saved some money, without acknowledging to myself what I was saving it for. And then I got a letter at work, informing me that they were now required to provide medical leave for anyone working over 15 hours weekly. And suddenly a lot of things came together, fast.
My mom has always been supportive of me, but she was not very happy to hear about this. After talking it over a lot, we ended up going together to a therapist who worked with both trans people and families - incidentally, our therapist was also nonbinary, and we had to take a break in our visits while they recovered from their own top surgery. We visited them a few times over a few months, and they suggested that I at least look into getting my surgery covered by insurance, and directed me toward the Johns Hopkins Center for Transgender Health. I had done research on several of the big names in top surgery, particularly those who do a lot of peri-areolar surgeries - I was very not into the idea of double incision, and knew that, while I was not the seventeen-year-old kid on T who's a sure thing for peri, I had a chance. But getting it covered would make the financial hit more bearable.
I did some research on insurance coverage. When it came time to renew my Medicaid coverage, I switched to an MCO that had a history of working with Johns Hopkins. I contacted them about finding a therapist to write a letter for me, and about getting a consultation - I expected to have a long wait to meet with Dr. Devin O'Brien-Coon, but they suggested that I come in much earlier and meet with Dr. Benny Tan, who had only recently come to work at the Hopkins center, so I got my letter and scheduled my appointment with him.
Dr. Tan had just started at the JH center when I had my consultation with him, and while he had a lot of previous experience doing breast cancer mastectomies, he was clearly a lot less familiar with top surgery. He was adamant that I was ineligible for peri-areolar surgery, and would have to have double incision. He seemed to have some weird misconceptions about the details - at one point he said that no one ever regains any nipple sensation after surgery (???), and when I mentioned the concept of the eventual shape of my chest being somewhat dependent on how much muscle I can develop through exercise he sort of laughed and said, "Well, maybe if you decide to become a bodybuilder." When I asked if I could see post-op pictures of some of the previous procedures the center had done, I was told no, that Dr. O'Brien-Coon didn't want to suggest that there was any guarantee of a specific kind of results. He seemed like a nice guy. He answered the questions I had, and my mom's. But I did not feel good about this.
At the same time, I was trying fruitlessly to get any information at all about whether I would, in fact, be able to get this covered by insurance. I won't go into the boring details of one million phone transfers, but after several days the question was resolved: because the insurance required a previous twelve-month period of hormone replacement therapy, I was out of luck. At this point I wasn't even upset - it just made it clearer that my original plan was what I was going to go with.
Finally, I paid $100 to have a consultation with Dr. Beverly Fischer in Lutherville. Dr. Fischer was one of the surgeons I'd been researching from the beginning - she's been performing surgeries since the 90s, including a lot of peri-areolar surgeries, and she also is the most local of the surgeons I'd looked into. I'd seen pictures online that people had posted of her work on people with body types very much like mine, and I was impressed. Dr. Fischer doesn't take any insurance (you can try to go through a process on your own afterward, and perhaps get at least a partial reimbursement from your insurance, but that's up to them), but I had the money saved, and I felt it was a fair trade to have a greater level of control over the experience.
Since Dr. Fischer has her own small facility, the consultation was very smooth and low-key. Again, my mom went with me (this was right before covid started, but even now she allows one visitor to come with a patient). She looked me over and assured me that I was definitely a candidate for peri (they all say "keyhole" there, which confused me, but I'm going to keep saying peri, by which I mean full circular incisions around the areola). We were given a breakdown of the cost ($9,700) and shown into a little room where they gave us a binder of pre- and post-op photos to look at. Again, her work is very impressive - my mom, who was not familiar with the different styles of surgery, was reassured that they did not look as scarred up as she was probably expecting. This was a much better experience than I had at Hopkins, enough to convince me.
Then the pandemic hit! Needless to say, things were on hold for a while.
The library I work at was closed for over two months. In June, we started working again, but with a very minimal schedule. I'd been doing almost double my baseline hours by filling in for vacant positions, but now I was working fifteen hours per week maximum, meaning I didn't lose any substitute pay for taking sick leave. So I called Dr. Fischer's office and made the soonest appointment I could, for September 16th. I made a 10% payment over the phone ($970) and scheduled my appointments for three weeks prior to surgery.
Three weeks before surgery:
I went to Dr. Fischer's office for my pre-op appointment. Because I'd already been measured during my consultation, this was mostly a lot of information and question-and-answer sessions with their surgical coordinator Shannon. My mom came with me (all of us wore masks, and we had temperature checks when we came in, as well as standard "have you had any covid symptoms or been out of state" worksheets to fill out).
Shannon brought out a set of the drains and showed us how they'd work (they are still stuck in me at the time of this writing, so I'm trying not to think about it too much!), and gave me a folder of pre- and post-op information, plus the sheet to give to my primary care doctor when I went to get my bloodwork done. The instructions were pretty standard - try to eat a lot of protein in the weeks before and after surgery (raises your red blood cell count so you recover faster), get up and walk around on the first day (helps the anesthesia junk work its way out of your body), don't lie on your back eating applesauce the whole time (you're not going to hurt yourself, live your life, just be gentle). Mentioned, but for some reason not included on the printed sheet: there's a one-day-post-op appointment the morning after, just to check everything out - this means that AFTER your surgery you shouldn't eat or drink after midnight, and through the morning, just in case there's an unexpected need to put you under to correct anything.
I brought them a check for the remainder of my payment - $8,730. As weird as it seems, seeing the money actually come out of my bank account didn't bother me at all. I'd saved that money with this in mind, so it seemed natural to finally use it.
They also gave me a stack of four prescriptions, which I filled on the way home: One pre-op anti-nausea pill, one pre-op Xanax, several post-op pain pills (hydrocodone and acetaminophen) and several post-op anti-nausea pills. Fortunately this was covered by my insurance, because I sure did NOT need all of these.
I went within the week to get the required physical and bloodwork at my regular doctor's office, and just handed them the sheet that said what results needed to be sent to Dr. Fischer. Apparently there was some kind of faxing error and I didn't find out for a couple weeks that they hadn't gotten the results, but that was fixed by some relatively simple phone calls. I'd recommend calling a week after the blood test to confirm that they've received everything.
I put in a request for six days off work - starting and ending on a Wednesday, with a normal weekend between. They usually recommend ten days, but I have a very low-activity job and only work short shifts, so they agreed that eight days would be fine. This is another factor that might have been different if I had been getting double-incision surgery, which I've heard can take a few more days of recovery.
Some days later, I got a call saying that the anesthesiologist wouldn't be able to be in on the Wednesday I was scheduled for. I was all set to move everything forward by a chunk of time when they clarified that no, they wanted me to come in one day earlier. Well, okay then. I added a Tuesday to my leave. I am told that I will need to get an "excuse note" to take back when I return to work, which I haven't asked for yet, but will probably get at my one-week-after appointment.
A few days before surgery:
This is the time to get things in order wherever you'll be staying. Of course you can't prepare for everything, but I did as much laundry as I could, made sure I had plenty of prepared food in the house, checked out a ton of books and DVDs from the library. Trimmed my hair and nails. Note that you are required to shave your armpits so the tape doesn't stick to them when they bandage you up - if you're not used to this, I recommend doing it a couple days in advance, because it's a Bad Time.
Night before surgery:
I got the usual confirmation call from them the Monday before my surgery date. I got everything together (medication. Sweatpants, button-up shirt, socks, slip-on shoes, COTTON underwear, which is the only kind you may wear in surgery. The folder of information. My old ipod and headphones). I went to bed relatively early as I knew I was going to be up early, though it might have been better to stay up and have a late snack before the midnight deadline.
Day of surgery:
September 15th - my surgery was scheduled for 9:30, and my arrival at 8:30. I was told to shower and wash my hair, to only use antibacterial soap (we had the Dial orange bar) for my body. I used baby shampoo on my hair, because I wanted something that wouldn't leave any weird residue, since I knew I wouldn't be able to wash it again for some days. Deodorant is allowed, but no lotion. Brushed my teeth. No food, no drink, no chewing gum.
I went to the surgery center with both my parents, but right now they're specifying only one guest per patient, so only my mom came in. There's a little retirement community and some stores around, so they had somewhere to hang out while they waited. I left my mom's phone number with them on a post-it so they could call her when they needed to come back for me.
I took my bag and went into one of the patient rooms, where I was given this hilariously large toga-looking thing to change into. I gave them my bag of meds, and they came back with a tiny bit of water for me to swallow the Xanax. The anti-nausea one dissolves in your mouth and tastes like strawberry mentos.
In a little tiny room with a ring light, they took a series of pictures of me from ribs to neck, at straight-on, side, and three-quarter views. Later I looked back at a computer screen and saw these pictures and briefly thought "who the hell's that?" Not that I'd had any doubts before that I was making the right decision, but that made it pretty clear.
Dr. Fischer came in after that, and drew about three dashed lines on my chest. My assumption is that these were so that when my skin shifted while I was lying down, she would be able to see what parts corresponded to where when I was upright. I asked briefly about what kind of resizing she would do around my nipples, which are very slightly asymmetrical, and she said that she uses a kind of template that would make them turn out a bit smaller, and, yes, the same size.
The anesthesiologist came in to give me the rundown on what would happen when I was taken into the operating room. I would put on a hairnet, I would get an IV that would put me out, then a mask of gas to keep me unconscious. A small tube would be put in the back of my throat to keep my airway open, and might give me a sore throat for a couple days after (spoiler: it did, but it wasn't too bad). Some kind of contraption of sleeves would periodically squeeze my legs to promote blood flow. All fairly standard, probably.
So they let my mom come in and hug me, and I said, "see you soon!" and they walked me back.
Sorry for the huge cliffhanger, but this thing is way longer than I thought! I'll be back with the post-op section in a few days, ok? And definitely comment any questions you might have. Recovery is boring.
TLDR:
Good luck to everybody reading this! I am feeling good. My recovery's been great so far and I'll go into more detail when I come back for the next part of this.

[Table] Asteroid Day AMA – We’re engineers and scientists working on a mission that could, one day, help save humankind from asteroid extinction. Ask us anything!

Source
There are several people answering: Paolo Martino is PM, Marco Micheli is MM, Heli Greus is HG, Detlef Koschny is DVK, and Aidan Cowley is AC.
Questions Answers
Can we really detect any asteroids in space with accuracy and do we have any real means of destroying it? Yes, we can detect new asteroids when they are still in space. Every night dozens of new asteroids are found, including a few that can come close to the Earth.
Regarding the second part of the question, the goal would be to deflect them more than destroy them, and it is technologically possible. The Hera/DART mission currently being developed by ESA and NASA will demonstrate exactly this capability.
MM
I always wanted to ask: what is worse for life on Earth - to be hit by a single coalesced asteroid chunk, or to be hit by a multiple smaller pieces of exploded asteroid, aka disrupted rubble pile scenario? DVK: This is difficult to answer. If the rubble is small (centimetres to meters) it is better to have lots of small ones – they’d create nice bright meteors. If the rubble pieces are tens of meters it doesn’t help.
Let’s say that hypothetically, an asteroid the size of Rhode Island is coming at us, it will be a direct hit - you’ve had the resources and funding you need, your plan is fully in place, everything you’ve wanted you got. The asteroid will hit in 10 years, what do you do? DVK: I had to look up how big Rhode Island is – a bit larger than the German Bundesland ‘Saarland’. Ok – this would correspond to an object about 60 km in diameter, right? That’s quite big – we would need a lot of rocket launches, this would be extremely difficult. I would pray. The good news is that we are quite convinced that we know all objects larger than just a few kilometers which come close to our planet. None of them is on a collision course, so we are safe.
the below is a reply to the above
Why are you quite convinced that you know all object of that size? And what is your approach in finding new celestial bodies? DVK: There was a scientific study done over a few years (published in Icarus 2018, search for Granvik) where they modelled how many objects there are out there. They compared this to the observations we have with the telescopic surveys. This gives us the expected numbers shown here on our infographic: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
There are additional studies to estimate the ‘completeness’ – and we think that we know everything above roughly a few km in size.
To find new objects, we use survey telescopes that scan the night sky every night. The two major ones are Catalina and Pan-STARRS, funded by NASA. ESA is developing the so-called Flyeye telescope to add to this effort https://www.esa.int/ESA_Multimedia/Images/2017/02/Flyeye_telescope.
the below is a reply to the above
Thanks for the answer, that's really interesting! It's also funny that the fist Flyeye deployed is in Sicily, at less than 100km from me, I really had no idea DVK: Indeed, that's cool. Maybe you can go and visit it one day.
the below is a reply to the original answer
What about Interstellar objects however, like Oumuamua? DVK: The two that we have seen - 'Oumuamua and comet Borisov - were much smaller than the Saarland (or Rhode Island ;-) - not sure about Borisov, but 'Oumuamua was a few hundred meters in size. So while they could indeed come as a complete surprise, they are so rare that I wouldn't worry.
Would the public be informed if an impending asteroid event were to happen? And, how would the extinction play out? Bunch of people crushed to death, knocked off our orbit, dust clouds forever? DVK: We do not keep things secret – all our info is at the web page http://neo.ssa.esa.int. The ‘risky’ objects are in the ‘risk page’. We also put info on really close approaches there. It would also be very difficult to keep things ‘under cover’ – there are many high-quality amateur astronomers out there that would notice.
In 2029 asteroid Apophis will fly really close to Earth, even closer than geostationary satellites. Can we use some of those satellites to observe the asteroid? Is it possible to launch very cheap cube sats to flyby Apophis in 2029? DVK: Yes an Apophis mission during the flyby in 2029 would be really nice. We even had a special session on that topic at the last Planetary Defense Conference in 2019, and indeed CubeSats were mentioned. This would be a nice university project – get me a close-up of the asteroid with the Earth in the background!
the below is a reply to the above
So you’re saying it was discussed and shelved? In the conference we just presented ideas. To make them happen needs funding - in the case of ESA the support of our member countries. But having something presented at a conference is the first step. One of the results of the conference was a statement to space agencies to consider embarking on such a mission. See here: https://www.cosmos.esa.int/documents/336356/336472/PDC_2019_Summary_Report_FINAL_FINAL.pdf/341b9451-0ce8-f338-5d68-714a0aada29b?t=1569333739470
Go to the section 'resolutions'. This is now a statement that scientists can use to present to their funding agencies, demonstrating that it's not just their own idea.
Thanks for doing this AMA! Did we know the Chelyabinsk meteor in 2013 (the one which had some great videos on social media) was coming? Ig not, how comes? Also, as a little side one, have there been any fatalities from impact events in the past 20 years? Unfortunately, the Chelyabinsk object was not seen in advance, because it came from the direction of the Sun where ground-based telescopes cannot look.
No known fatalities from impacts have happened in the past 20 years, although the Chelyabinsk event did cause many injuries, fortunately mostly minor.
MM
the below is a reply to the above
How often do impacts from that direction happen, compared to impacts from visible trajectories? In terms of fraction of the sky, the area that cannot be easily scanned from the ground is roughly a circle with a radius of 40°-50° around the current position of the Sun, corresponding to ~15% of the total sky. However, there is a slight enhancement of objects coming from that direction, therefore the fraction of objects that may be missed when heading towards us is a bit higher.
However, this applies only when detecting an asteroid in its "final plunge" towards the Earth. Larger asteroids can be spotted many orbits earlier, when they are farther away and visible in the night side of the sky. Their orbits can then be determined and their possible impacts predicted even years or decades in advance.
MM
There must be a trade-off when targeting asteroids as they get closer to Earth, is there a rule of thumb at what the best time is to reach them, in terms of launch time versus time to reach the asteroid and then distance from Earth? DVK: Take e.g. a ‘kinetic impactor’ mission, like what DART and Hera are testing. Since we only change the velocity of the asteroid slightly, we need to hit the object early enough so that the object has time to move away from it’s collision course. Finding out when it is possible to launch requires simulations done by our mission analysis team. They take the strength of the launcher into account, also the available fuel for course corrections, and other things. Normally each asteroid has its own best scenario.
Do you also look at protecting the moon from asteroids? Would an impact of a large enough scale potentially have major impacts on the earth? DVK: There are programmes that monitor the Moon and look for flashes from impacting small asteroids (or meteoroids) - https://neliota.astro.noa.g or the Spanish MIDAS project. We use the data to improve our knowledge about these objects. These programmes just look at what is happening now.
For now we would not do anything if we predicted a lunar impact. I guess this will change once we have a lunar base in place.
Why aren't there an international organisation comprised of countries focused on the asteroid defence? Imagine like the organisation with multi-billion $ budget and program of action on funding new telescopes, asteroid exploration mission, plans for detection of potentially dangerous NEA, protocols on action after the detection - all international, with heads of states discussing these problems? DVK: There are international entities in place, mandated by the UN: The International Asteroid Warning Network (http://www.iawn.net) and the Space Mission Planning Advisory Group (http://www.smpag.net). These groups advise the United Nations. That is exactly where we come up with plans and protocols on action. But: They don’t have budget – that needs to come from elsewhere. I am expecting that if we have a real threat, we would get the budget. Right now, we don’t have a multi-billion budget.
the below is a reply to someone else's answer
There is no actual risk of any sizable asteroids hitting earth in the foreseeable future. Any preparation for it would just be a waste of money. DVK: Indeed, as mentioned earlier, we do not expect a large object to hit is in the near future. We are mainly worried about those in the size range of 20 m to 40 m, which happen on average every few tens of years to hundreds of years. And where we only know a percent of them or even less.
President Obama wanted to send a crewed spacecraft to an asteroid - in your opinion is this something that should still be done in the future, would there be any usefulness in having a human being walk/float on an asteroid's surface? DVK: It would definitely be cool. I would maybe even volunteer to go. Our current missions to asteroids are all robotic, the main reason is that it is much cheaper (but still expensive) to get the same science. But humans will expand further into space, I am sure. If we want to test human exploration activities, doing this at an asteroid would be easier than landing on a planet.
this is another reply Yes, but I am slightly biased by the fact that I work at the European astronaut centre ;) There exist many similarities to what we currently do for EVA (extra vehicular activities) operations on the International Space Station versus how we would 'float' around an asteroid. Slightly biased again, but using such a mission to test exploration technologies would definitely still have value. Thanks Obama! - AC
I've heard that some asteroids contains large amounts of iron. Is there a possibility that we might have "space mines" in the far away future, if our own supply if iron runs out? Yes, this is a topic in the field known as space mining, part of what we call Space Resources. In fact, learning how we can process material we might find on asteroids or other planetary bodies is increasingly important, as it opens up the opportunities for sustainable exploration and commercialization. Its a technology we need to master, and asteroids can be a great target for testing how we can create space mines :) - AC
By how much is DART expected to deflect Didymos? Do we have any indication of the largest size of an asteroid we could potentially deflect? PM: Didymos is a binary asteroid, consisting of a main asteroid Didymos A (~700m) and a smaller asteroid Didymos B (~150m) orbiting around A with a ~12 hours period. DART is expected to impact Didymos B and change its orbital period w.r.t. Didymos A of ~1%. (8 mins)
The size of Didymos B is the most representative of a potential threat to Earth (the highest combination of probability and consequence of impacts), meaning smaller asteroids hit the Earth more often but have less severe consequences, larger asteroids can have catastrophic consequences but their probability of hitting the earth is very very low.
the below is a reply to the above
Why is there less probability of larger asteroids hitting earth? DVK: There are less large objects out there. The smaller they are, the more there are.
the below is a reply to the original answer
Is there any chance that your experiment will backfire and send the asteroid towards earth? PM: Not at all, or we would not do that :) Actually Dimorphos (the Didymos "moon") will not even leave its orbit around Didymos. It will just slightly change its speed.
I'm sure you've been asked this many times but how realistic is the plot of Armageddon? How likely is it that our fate as a species will rely on (either) Bruce Willis / deep sea oil drillers? Taking into consideration that Bruce Willis is now 65 and by the time HERA is launched he will be 69, I do not think that we can rely on him this time (although I liked the movie).
HERA will investigate what method we could use to deflect asteroid and maybe the results will show that we indeed need to call the deep sea oil drillers.
HG
the below is a reply to the above
So then would it be easier to train oil drillers to become astronauts, or to train astronauts to be oil drillers? I do not know which one would be easier since I have no training/experience of deep see oil drilling nor becoming an astronaut, but as long as the ones that would go to asteroid have the sufficient skills and training (even Bruce Willis), I would be happy.
HG
If budget was no object, which asteroid would you most like to send a mission to? Nice question! For me, I'd be looking at an asteroid we know something about, since I would be interested in using it for testing how we could extract resources from it. So for me, I would choose Itokawa (https://en.wikipedia.org/wiki/25143_Itokawa), which was visited by Hayabusa spacecraft. So we already have some solid prospecting carried out for this 'roid! - AC
this is another reply Not sure if it counts as an asteroid, but Detlef and myself would probably choose ʻOumuamua, the first discovered interstellar object.
MM
the below is a reply to the above
Do we even have the capability to catch up to something like that screaming through our solar system? That thing has to have a heck of a velocity to just barrel almost straight through like that. DVK: Correct, that would be a real challenge. We are preparing for a mission called 'Comet Interceptor' that is meant to fly to an interstellar object or at least a fresh comet - but it will not catch up with it, it will only perform a short flyby.
https://www.esa.int/Science_Exploration/Space_Science/ESA_s_new_mission_to_intercept_a_comet
After proving to be able to land on one, could an asteroid serve as a viable means to transport goods and or humans throughout the solar system when the orbit of said asteroid proves beneficial. While it is probably quite problematic to land the payload, it could save fuel or am I mistaken? Neat idea! Wonder if anyone has done the maths on the amount of fuel you would need/save vs certain targets. - AC
PM: To further complement, the saving is quite marginal indeed because in order to land (softly) on the asteroid you actually need to get into the very same orbit of that asteroid . At that point your orbit remains the same whether you are on the asteroid or not..
can the current anti-ballistic missiles systems intercept a terminal phase earth strike asteroid? or it is better to know beforehand and launch an impacting vehicle into space? DVK: While I do see presentations on nuclear explosions to deflect asteroids at our professional meetings, I have not seen anybody yet studying how we could use existing missile systems. So it's hard to judge whether existing missiles would do the job. But in general, it is better to know as early as possible about a possible impact and deflect it as early as possible. This will minimize the needed effort.
How much are we prepared against asteroid impacts at this moment? DVK: 42… :-) Seriously – I am not sure how to quantify ‘preparedness’. We have international working groups in place, mentioned earlier (search for IAWN, SMPAG). We have a Planetary Defence Office at ESA, a Planetary Defense Office at NASA (who spots the difference?), search the sky for asteroids, build space missions… Still we could be doing more. More telescopes to find the object, a space-based telescope to discover those that come from the direction of the Sun. Different test missions would be useful, … So there is always more we could do.
Have you got any data on the NEO coverage? Is there estimations on the percentage of NEOs we have detected and are tracking? How can we improve the coverage? How many times have asteroids been able to enter earths atmosphere without being detected beforehand? Here’s our recently updated infographics with the fraction of undiscovered NEOs for each size range: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
As expected, we are now nearly complete for the large ones, while many of the smaller ones are still unknown.
In order to improve coverage, we need both to continue the current approach, centered on ground-based telescopes, and probably also launch dedicated telescopes to space, to look at the fraction of the sky that cannot be easily observed from the ground (e.g., towards the Sun).
Regarding the last part of your question, small asteroids enter the Earth atmosphere very often (the infographics above gives you some numbers), while larger ones are much rarer.
In the recent past, the largest one to enter our atmosphere was about 20 meters in diameter, and it caused the Chelyabinsk event in 2013. It could not be detected in advance because it came from the direction of the Sun.
We have however detected a few small ones before impact. The first happened in 2008, when a ~4-meter asteroid was found to be on a collision course less than a day before impact, it was predicted to fall in Northern Sudan, and then actually observed falling precisely where (and when) expected.
MM
this is another reply >After
DVK: And to add what MM said - Check out http://neo.ssa.esa.int. There is a ‘discovery statistics’ section which provides some of the info you asked about. NASA is providing similar information here https://cneos.jpl.nasa.gov/stats/. To see the sky which is currently covered by the survey telescopes, you need to service of the Minor Planet Center which we all work together with: http://www.minorplanetcenter.org, ‘observers’, ‘sky coverage’. That is a tool we use to plan where we look with our telescopes, so it is a more technical page.
Are there any automatic systems for checking large numbers of asteroids orbits, to see if the asteroid's orbit is coming dangerously close to Earth, or is it done by people individually for every asteroid? I ask it because LSST Rubin is coming online soon and you know it will discover a lot of new asteroids. Yes, such systems exist, and monitor all known and newly discovered asteroids in order to predict possible future impacts.
The end result of the process is what we call "risk list": http://neo.ssa.esa.int/risk-page
It is automatically updated every day once new observational data is processed.
MM
What are your favourite sci-fi series? DVK: My favorites are ‘The Expanse’, I also liked watching ‘Salvation’. For the first one I even got my family to give me a new subscription to a known internet streaming service so that I can see the latest episodes. I also loved ‘The Jetsons’ and ‘The Flintstones’ as a kid. Not sure the last one counts as sci-fi though. My long-time favorite was ‘Dark Star’.
this is another reply Big fan of The Expanse at the moment. Nice, hard sci-fi that has a good impression of being grounded in reality - AC
this is another reply When I was a kid I liked The Jetsons, when growing up Star Trek, Star wars and I also used to watch with my sister the 'V'.
HG
When determining the potential threat of a NEA, is the mass of an object a bigger factor or size? I'm asking because I'm curious if a small but massive object (say, with the density of Psyche) could survive atmospheric entry better than a comparatively larger but less massive object. The mass is indeed what really matters, since it’s directly related with the impact energy.
And as you said composition also matters, a metal object would survive atmospheric entry better, not just because it’s heavier, but also because of its internal strength.
MM
What are your thoughts on asteroid mining as portrayed in sci-fi movies? Is it feasible? If so would governments or private space programs be the first to do so?What type of minerals can be found on asteroids that would merit the costs of extraction? Certainly there is valuable stuff you can find on asteroids. For example, the likely easiest material you can harvest from an asteroid would be volatiles such as H2O. Then you have industrial metals, things like Iron, Nickel, and Platinum group metals. Going further, you can break apart many of the oxide minerals you would find to get oxygen (getting you closer to producing rocket fuel in-situ!). Its feasible, but still needs alot of testing both here on Earth and eventually needs to be tested on a target. It may be that governments, via agencies like ESA or NASA, may do it first, to prove the principles somewhat, but I know many commercial entities are also aggresively working towards space mining. To show you that its definitely possible, I'd like to plug the work of colleagues who have processed lunar regolith (which is similar to what you may find on asteroids) to extract both oxygen and metals. Check it out here: http://www.esa.int/ESA_Multimedia/Images/2019/10/Oxygen_and_metal_from_lunar_regolith
AC
Will 2020's climax be a really big rock? DVK: Let's hope not...
Considering NASA, ESA, IAU etc. is working hard to track Earth-grazing asteroids, how come the Chelyabinsk object that airburst over Russia in 2013 came as a total surprise? The Chelyabinsk object came from the direction of the Sun, where unfortunately ground-based telescopes cannot look at. Therefore, it would not have been possible to discover it in advance with current telescopes. Dedicated space telescopes are needed to detect objects coming from this direction in advance.
MM
the below is a reply to the above
Is this to say that it was within specific solid angles for the entire time that we could have observed it given its size and speed? Yes, precisely that. We got unlucky in this case.
MM
Have any of you read Lucifer's Hammer by Larry Niven? In your opinion, how realistic is his depiction of an asteroid strike on Earth? DVK: I have – but really long ago, so I don’t remember the details. But I do remember that I really liked the book, and I remember I always wanted to have a Hot Fudge Sundae when reading it.
I was thinking about the asteroid threat as a teen and came up with this ideas (Hint: they are not equally serious, the level of craziness goes up real quick). Could you please comment on their feasibility? 1. Attaching a rocket engine to an asteroid to make it gradually change trajectory, do that long in advance and it will miss Earth by thousands of km 2. Transporting acid onto asteroid (which are mainly metal), attaching a dome-shaped reaction chamber to it, using heat and pressure to then carry out the chemical reaction to disintegrate asteroids 3. This one is even more terrible than a previous one and totally Dan Brown inspired — transporting antimatter on asteroid, impacting and causing annihilation. Thank you for this AMA and your time! DVK: Well the first one is not so crazy, I have seen it presented... the difficulty is that all asteroids are rotating in one way or another. So if you continuously fire the engine it would not really help. You'd need to switch the engine on and off. Very complex. And landing on an asteroid is challenging too. Just using the 'kinetic impactor' which we will test with DART/Hera (described elsewhere in this chat) is simpler. Another seriously proposed concept is to put a spacecraft next to an asteroid and use an ion engine (like we have on our Mercury mission BepiColombo) to 'push' the asteroid away.
As for 2 and 3 I think I will not live to see that happening ;-)
What is the process to determine the orbit of a newly discovered asteroid? The process is mathematically quite complex, but here's a short summary.
Everything starts with observations, in particular with measurements of the position of an asteroid in the sky, what we call "astrometry". Discovery telescopes extract this information from their discovery images, and make it available to everybody.
These datapoints are then used to calculate possible trajectories ("orbits") that pass through them. At first, with very few points, many orbits will be possible.
Using these orbits we can extrapolate where the asteroid will be located during the following nights, use a telescope to observe that part of the sky, and locate the object again.
From these new observations we can extract new "astrometry", add it to the orbit determination, and see that now only some of the possible orbits will be compatible with the new data. As a result, we now know the trajectory better than before, because a few of the possible orbits are not confirmed by the new data.
The cycle can then continue, with new predictions, new observations, and a more accurate determination of the object's orbit, until it can be determined with an extremely high level of accuracy.
MM
What are some asteroids that are on your "watchlist"? We have exactly that list on our web portal: http://neo.ssa.esa.int/risk-page
It's called "risk list", and it includes all known asteroids for which we cannot exclude a possible impact over the next century. It is updated every day to include newly discovered asteroids, and remove those that have been excluded as possible impactors thanks to new observations.
MM
the below is a reply to the above
That's quite a list!! Do you guys ever feel stressed or afraid when you have to add another dangerous candidate (and by dangerous I mean those above 200m) is added to this Risk List? Yes, when new dangerous ones are added it's important that we immediately do our best to gather more data on them, observing them with telescopes in order to get the information we need to improve our knowledge of their orbit.
And then the satisfaction of getting the data needed to remove one from the list is even greater!
MM
What inspired you to go into this field of study? I was fascinated by astronomy in general since I was a kid, but the actual "trigger" that sparked my interest in NEOs was a wonderful summer course on asteroids organized by a local amateur astronomers association. I immediately decided that I would do my best to turn this passion into my job, and I'm so happy to have been able to make that dream come true.
MM
this is another reply DVK: I started observing meteors when I was 14, just by going outside and looking at the night sky. Since then, small bodies in the solar system were always my passion.
As a layperson, I still think using nuclear weapons against asteroids is the coolest method despite better methods generally being available. Do you still consider the nuclear option the cool option, or has your expertise in the field combined with the real-life impracticalities made it into a laughable/silly/cliche option? DVK: We indeed still study the nuclear option. There are legal aspects though, the ‘outer space treaty’ forbids nuclear explosions in space. But for a large object or one we discover very late it could be useful. That’s why we have to focus on discovering all the objects out there as early as possible – then we have time enough to use more conventional deflection methods, like the kinetic impactor (the DART/Hera scenario).
It seems like doing this well would require international cooperation, particularly with Russia. Have you ever reached out to Russia in your work? Do you have a counterpart organization there that has a similar mission? DVK: Indeed international cooperation is important - asteroids don't know about our borders! We work with a Russian team to perform follow-up observations of recently discovered NEOs. Russia is also involved in the UN-endorsed working groups that we have, IAWN and SMPAG (explained in another answer).
how much can experts tell from a video of a fireball or meteor? Can you work out what it's made of and where it came from? https://www.reddit.com/space/comments/hdf3xe/footage_of_a_meteor_at_barrow_island_australia/?utm_source=share&utm_medium=web2x If multiple videos or pictures, taken from different locations, are available, then it's possible to reconstruct the trajectory, and extrapolate where the object came from.
Regarding the composition, it's a bit more difficult if nothing survives to the ground, but some information can be obtained indirectly from the fireball's color, or its fragmentation behavior. If a spectral analysis of the light can be made, it's then possible to infer the chemical composition in much greater detail.
MM
I've always wanted to know what the best meteorite buying site is and what their average price is?? DVK: Serious dealers will be registered with the 'International Meteorite Collectors Association (IMCA)' - https://www.imca.cc/. They should provide a 'certificate of authenticity' where it says that they are member there. If you are in doubt, you can contact the association and check. Normally there are rough prices for different meteorite types per gram. Rare meteorites will of course be much more expensive than more common ones. Check the IMCA web page to find a dealer close to you.
Just read through Aidans link to the basaltic rock being used as a printing material for lunar habitation. There is a company called Roxul that does stone woven insulation that may be able to shed some light on the research they have done to minimize their similarity to asbestos as potentially carcinogenic materials deemed safe for use in commercial and residential applications. As the interior surfaces will essentially be 3D printed lunar regolith what are the current plans to coat or dampen the affinity for the structure to essentially be death traps for respiratory illness? At least initially, many of these 3d printed regolith structures would not be facing into pressurised sections, but would rather be elements placed outside and around our pressure vessels. Such structures would be things like radiation shields, landing pads or roadways, etc. In the future, if we move towards forming hermetically sealed structures, then your point is a good one. Looking into terrestrial solutions to this problem would be a great start! - AC
What kind of career path does it take to work in the asteroid hunting field? It's probably different for each of us, but here's a short summary of my own path.
I became interested in asteroids, and near-Earth objects in particular, thanks to a wonderful summer course organized by a local amateur astronomers association. Amateur astronomers play a great role in introducing people, and young kids in particular, to these topics.
Then I took physics as my undergrad degree (in Italy), followed by a Ph.D. in astronomy in the US (Hawaii in particular, a great place for astronomers thanks to the exceptional telescopes hosted there).
After finishing the Ph.D. I started my current job at ESA's NEO Coordination Centre, which allowed me to realize my dream of working in this field.
MM
this is another reply DVK: Almost all of us have a Master's degree either in aerospace engineering, mathematics, physics/astronomy/planetary science, or computer science. Some of us - as MM - have a Ph.D. too. But that's not really a requirement. This is true for our team at ESA, but also for other teams in other countries.
What is the likelihood of an asteroid hitting the Earth In the next 200 years? It depends on the size, large ones are rare, while small ones are much more common. You can check this infographics to get the numbers for each size class: https://www.esa.int/ESA_Multimedia/Images/2018/06/Asteroid_danger_explained
MM
Have you played the Earth Defence Force games and if you have, which one is your favourite? No I have not played the Earth Defence Force games, but I just looked it up and I think I would liked it. Which one would you recommend?
HG
How close is too close to earth? Space is a SUPER vast void so is 1,000,000 miles close, 10,000,000? And if an asteroid is big enough can it throw earth off its orbit? DVK: Too close for my taste is when we compute an impact probability > 0 for the object. That means the flyby distance is zero :-) Those are the objects on our risk page http://neo.ssa.esa.int/risk-page.
If an object can alter the orbit of another one, we would call it planet. So unless we have a rogue planet coming from another solar system (verrry unlikely) we are safe from that.
How can I join you when I'm older? DVK: Somebody was asking about our career paths... Study aerospace engineering or math or physics or computer science, get a Masters.
