Y'know... I feel like I need another label

I feel contented with labeling as agender but there's some things I personally feel uncomfortable with how other members perceive it and express agenderness. It's not them of course the problem is in myself and how I'm probably not really fitting with the community in certain ways so maybe someone here could give me some ideas on what other label (or more than label I would say community) could be more fitting for what I experience.
As I understand it, agender is just not caring for anything gender relater, not even in how you present it or who you are, nothing. You can be agender and change absolutely nothing before or after, not even your likes or presentation, is like you are comfortable being whatever gender you were seen as before (either male or female) and you decide to change that to agender but only by name and people can even keep calling you either or, so nothing's really changed.
My thing is that I DO would like things to change when people hear "oh I'm this" and they'll understand that things are actually going to change, and that I do feel uncomfortable with the things as they are right now.
As I said, maybe I'm not agender then, maybe I mistakenly thought it was going towards that. And I do feel like for me my gender doesn't matter, I don't really care, I could be happy with either or or none or all, but the problem is that others really do care and will make it so nothing changes, all the stereotyping, the preconceptions, how they perceive you, and I'm not really that agreeable and uncaring of that nor feel comfortable with it. Maybe others actually do not care how they perceive them regardless of the gender other sees them as and they can let people still call them she and use dresses, act girly and let others project into them what they already know, but I do care and it directly affects my relationship with people and how they perceive me despite me understanding that gender association shouldn't dictate anything about yourself, and I feel it's way easier to take matters yourself than expect them to understand that they have to change their way of thinking and regardless of gender they have to be respectful and not stereotype, etc, because it comes back to the same thing. No matter what gender you present as others see you as (specifically male and female) they will still treat you like they want. At least that's my reality in the context I am in.
I want to be stripped out of gender altogether so is not either or, is none at all and fuck you, is more like a sign of protest against how much agency they have over you simply by the language. For that same reason I feel like my pronouns are specifically they/them to not leave opportunity to make them anything else. As neutral, separated, and different, like an actual other option that is a different group to male and female and the concept of gender. Is none gender, is none stereotype or none pride over one's vision of uniqueness by how much feminine or masculine you are.
I could probably choose to go by just non-binary but I've seen that that in itself is understood as more like a combination of both male and female so much so that it gets confused but it's still a thing were you add from both, not take out. I would say I'm more comparable to a robot or an AI (the ones that people don't infuse gender in, I hate when they do that, like that one Sophia robot... poor poor child... And more like theta one one because they don't even have a gendered voice), or to a basic blank human.
Maybe I'm more like neutrois but I'm not that versed in their concept of themselves. Or Voidpunk but I too don't know much about them, I think it's just a sarcastic reaction to how people perceive being a human in general.
Some can argue that I could still be agender and it's ok to demand specific things while agender but I think I will be contradictory to the agender cause which is "I just don't care and label me as whatever you want, nothing changes because I'm just me".
Do someone has any suggestions of other labels I could go by? Not for the label itself, that's silly, but for the community, I want to find people like me so I don't feel alone in this.

MAME 0.221

MAME 0.221

Our fourth release of the year, MAME 0.221, is now ready. There are lots of interesting changes this time. We’ll start with some of the additions. There’s another load of TV games from JAKKS Pacific, Senario, Tech2Go and others. We’ve added another Panorama Screen Game & Watch title: this one features the lovable comic strip canine Snoopy. On the arcade side, we’ve got Great Bishi Bashi Champ and Anime Champ (both from Konami), Goori Goori (Unico), the prototype Galun.Pa! (Capcom CPS), a censored German version of Gun.Smoke, a Japanese location test version of DoDonPachi Dai-Ou-Jou, and more bootlegs of Cadillacs and Dinosaurs, Final Fight, Galaxian, Pang! 3 and Warriors of Fate.
In computer emulation, we’re proud to present another working UNIX workstation: the MIPS R3000 version of Sony’s NEWS family. NEWS was never widespread outside Japan, so it’s very exciting to see this running. F.Ulivi has added support for the Swedish/Finnish and German versions of the HP 86B, and added two service ROMs to the software list. ICEknight contributed a cassette software list for the Timex NTSC variants of the Sinclair home computers. There are some nice emulation improvements for the Luxor ABC family of computers, with the ABC 802 now considered working.
Other additions include discrete audio emulation for Midway’s Gun Fight, voice output for Filetto, support for configurable Toshiba Pasopia PAC2 slot devices, more vgmplay features, and lots more Capcom CPS mappers implemented according to equations from dumped PALs. This release also cleans up and simplifies ROM loading. For the most part things should work as well as or better than they did before, but MAME will no longer find loose CHD files in top-level media directories. This is intentional – it’s unwieldy with the number of supported systems.
As usual, you can get the source and 64-bit Windows binary packages from the download page. This will be the last month where we use this format for the release notes – with the increase in monthly development activity, it’s becoming impractical to keep up.

[Review] Ranking all the Switch shmups Ep25 - Q-YO Blaster

There was a time when I believed that shmups could only feature ships. Then games like Parodius came to challenge that belief. If an Octopus can be the player, then anything is possible. And don’t get me started on Cho Aniki…
When it comes to unusual characters for a shmup, it’s always a coin toss. They could either be the most fun you’ve had in a while or end up being a disappointment. Time for me to toss this coin!
Publisher: Forever entertainment
Platform: Nintendo Switch
Release date: Jun 27, 2019
Price: $9.99
Tate: You can, but you might need to tilt your head
Q-YO Blaster is by far the strangest 2D horizontal shmup I’ve reviewed for this ranking list. The gameplay and mechanics aren’t anything particularly odd, but there’s something about the presentation and the lore which is legitimately fascinating. For some reason it feels like a game developed by someone out of this world who learned about our culture through animated movies.

SATURDAY MORNING SHMUP

One of the aspects that tipped me over the edge when deciding what to review was the art style. Keeping up with the animation vibe, Q-YO Blaster sports an old school cartoon art style. Enemies will be colorful creatures with quirky details such as baseball caps, big eyes or even Mickey Mouse styled gloves. Their animations are equally as comical whether it is their attack animation of their death animation.
Of course, cartoony can be used to describe maybe half of the style. The other half is probably more akin to a sci-fi coat of paint. Along the many bugs and animals, there’s also a great deal of robots, monsters, heavy weaponry and even blood running rampant (or maybe it’s oil?). It does makes sense considering the bugs came from space, and it definitely adds a touch of mystery when navigating through the stages of Q-YO Blaster.

EVERYONE IS HERE!

My original expectation of the game was to have a few pilots including the Q-YO, floating dog head from the screenshots and doggy airplane. Little did I know that Q-YO Blaster has more pilots than I have fingers in both of my hands.
Pilots are arranged into 3 different teams. Each pilot has different stats which include damage, speed and fire. The teams can have +damage, +endurance or a mixture of both. Fortunately, despite the outrageous pilot designs and sprites, their hitboxes are all the same. After picking your pilot, you can pick one of 7 different special weapons to round out your style. From whichever angle you want to watch it, Q-YO Blaster offers a crazy amount of customization options.
The defining feature of each team is their assistant. Assistant are powerful screen-wide effects that trigger once you fill the assistant gauge. The gauge can be filled by continuously shooting and defeating enemies. Once filled, you can hold the fire button to unleash its effect. The effects are a screen explosion that clears bullets, a temporary shield or a 360 barrage of missiles.

BUILDING YOUR OFFENSE

With all of the previous elements combined, you can play as one of 112 possible combinations of team, pilot and special weapons.
In terms of weapons at your disposal, you have 3: your basic shot, your special weapon and your assistant. Your basic shot is an infinite gun that shoots bullets straight ahead with some degree of spread. The first shot is always straight, so you can opt for manual rapid fire to keep a straight line of fire. Alternatively, you can hold the button and just auto-fire.
Occasionally, you’ll find power-up weapons flying around the stage. This power-ups will grant you a limited weapon when collected. These extra weapons are considerably faster than your basic shot at the cost of having limited ammo. They also have a unique effect on their very first shot, once more giving you a choice between manually shooting or going with the auto-fire.

ALSO BUILD YOUR DEFENSE

One defensive tool you have at your disposal is the pulse. Pulse clears every bullet on screen and turns them into gems. When collected, this gems will increase the level of your special weapon gauge. This special weapon will be whatever you picked on the character select, and has 3 different levels of strength depending on how many gems you have collected. It also comes with some slight invulnerability so you can use it to get out of sticky situations.
The caveat of pulse is that you can only carry 3 stocks, and it is only refilled by collecting extra pulse power-ups. I have mixed feelings about this limitation, as I feel it plays an integral part of your offensive game plan. Its hard limit prevents any smart usage other than just a get-out-of-jail card. I would have loved if it had a gauge like the assistant, as that would have created a balance between building pulse and shooting your special.

LITTLE ADVENTURES

Every stage carries a sort of familiar scenery. I like to think of it as Toy Story levels. Considering the characters are Q-YOs and bugs, it makes sense for the scenery to be a relatively small scale such as houses or gardens. I find them to be very charming, or it might be just my nostalgia kicking in because I grew up with Toy Story. Nonetheless, I really dig the stages.
At the end of each stage, there’s a very comical boss waiting for you. These bosses represent whichever vibe you got from the level. For example, the boss of the garden level is none other than Queen Bee herself. Bosses turn the action up to 11 featuring huge bullet patterns and significantly more aggressive tactics. My one complaint about the bosses is that they feel a lot like a flow chart. They have a couple of attacks and will cycle through them in the same order all the time. Assuming you can dodge them, it’s only a matter of repeating the same moves over and over until the boss goes down. This is even worse on the harder difficulties when the bosses have much more HP.
The most interesting aspects of the stages are the end rewards. Similar to many rogue-lite games, clearing a stage will let you choose a perk for the rest of your adventure. The perks are always the same, but include upgrades such as increased speed, faster shots or even 1ups.

STORY TIME!

Despite being a shmup, I really recommend paying attention to the story! It really is something else! I don’t think it actually makes much sense, but there’s something about the way it’s told that crashes my brain. It does have some powerful moments as well! Including that one stage with the sad music and the rain. I don’t want to spoil it, but it really hit me hard.
I didn’t delve too much into game modes, but there’s basically classic and arcade. Classic is your base mode with the entire story and 3 selectable difficulties. If you don’t want to go through the story every time (even though it is skippable), then arcade mode is for you. Arcade mode features 0 cutscenes, so it’s all fun and games. Arcade mode is also much harder, but has 99 continues.

HARDER ISN’T ALWAYS BETTER

I have to make one of my classic parenthesis to talk about difficulty. Being honest, I think the expert difficulty and to some extent arcade are pretty terrible. The reason is because of the way the game is balanced as a result of them. Harder difficulties feature faster bullets and more complex patterns, but also feature increased vitality for the enemies. The increased lethality of the enemies makes for a hearty challenge, but all good is wiped out by the tedium of enemy endurance.
What I found out was that enemies are very durable in the harder difficulties. Rather than creating a fun challenge, it makes it incredibly hard to destroy enemies. Most enemies feel like sponges that just refuse to die unless you have a special weapon. Some enemies feel outright impossible to kill before they leave the screen, an issue which hurts a lot when it comes to homing projectiles that need to be destroyed. Fun and dynamic dog fights become grindy situations where you focus on a single ship and fail to destroy it while having others flood the screen. I really think harder difficulties would have been better without the added HP on enemies but retaining the faster bullets and harder patterns.

SLOW AND STEADY DOESN’T WIN THE RACE

While on the topic of hard difficulties, the homing bullets are another culprit behind the reason the difficulty isn’t fun. I’ve never been a fan of homing attacks as they feel cheap, but it feels like it wasn’t play tested because some slower ships can’t actually avoid a homing shot without the speed upgrade. To be fair, no one shoots homing bullets on stage 1, so taking speed is utmost priority.
One thing I do like about speed is that most boss patterns allow you to dodge at high speed. You can’t slow your speed, so it’s nice that there isn’t finesse required to survive some waves.

A LITTLE BIT MORE TIME IN THE OVEN

If I was on a game show about quick words and someone mentioned “Q-YO Blaster”, my response would be “rough”. While some aspects of the game are really cool, there are other where it feels a little bit incomplete. Some enemies don’t match the visual quality of others such as Major Tomm. The UI and menus also seem to come from a prototype version.
There’s also a sort of bug where if you die and use a credit, the game immediately pauses. Not a big deal, but it feels out of place. The customization screen is also all sorts of blurry. You can’t remap controls either, which is a shame considering the shoulder buttons would really come in handy.
Most of these issues aren’t a big deal by themselves, but they taint the final product by making it feel a little like shovelware. The game is really fun though, so it is sad to think about having it fall under that umbrella.

FINAL WORDS

So the mandatory question is, is it fun? It definitely is! With its bizarre and unsettling vibe, Q-YO Blaster is still tons of fun to play. While there is certainly a lot of room for improvement, Q-YO Blaster is still a solid choice for a shmup if you are fan of the cartoon style, of the horizontal shmup format or just a fan of little critters in general.

2064: Read Only Memories: Full Review on Switch. (No Spoilers)

TLDR; 7/10. It has a pretty good story, great visual style, decision making that will alter the ending, and it is also LGBT friendly. However, it has some pacing problems, it can get tedious near the end, and there is a random factor to some of the puzzles that may require extensive trial and error. Some of the voice actors also could have used more direction. If you are a fan of point and click adventure games, check this out! Also, it has voice acting from tons of celebrities/Youtubers.


Welcome back to yet another review.Been a while since i've done one. Today we are looking at 2064: Read Only Memories, which is currently on sale for a LOT. Had some left over bucks from picking up Assassins Creed 3 (Will review that later) so picked this up.

This game is a cyber-punk, point and click adventure game set in the future, with lots of themes of identity and life and all that good stuff. Is it worth your time? Lets' find out.

Quick Disclaimer: there are no spoilers in this review:

PREMISE


The plot takes place, as you'd expect from the title, in the year 2064. You play as an (initially) nameless protagonist, working as a freelance journalist reviewing products on the "Mesh." (Internet) In this era you live in, the world is run by a mix of humans and robots, as well as "Hybrids," People who have infused their DNA with animals. One day, a robot by the name of "Turing" enters your home out of nowhere with a message: an old friend of yours, Hayden, has gone missing. Hayden is the creator of Turing, who says that their creator has been kidnapped. Turning is unique, in that they have a personality component unlike any other ROM in the world.

It's up to you to investigate his disappearance, and figure out what is going on: who kidnapped him, and why? What's the deal with Turing, and their unique abilities? From there you investigate areas, talk to people, make decisions and dialogue options, as well as solve puzzles. The plot starts simple, but quickly gets more dark and thematic as you progress.

So, a few things to note. First, this game is suuuuuuuuper heavy on social political stuff. I'm talking gendeidentity, sexuality, etc. There's a lot of little things that you'll find: First, you eventually get to name the protagonist (who is never shown by face) and you can chose pronouns (he,she,they) that you want to go by. So if you identify as non binary, or anything like that, there are options for you. Next, there are several gay/lesbian characters you will encounter. Finally, to go back to the "Hybrid" individuals, these can basically be seen as furries. If any of this bothers you, you may not like this game, but I believe the game is not particular "social justice" or "woke" about any of it: the main story is not really about these things, rather these are sub elements of the world around you. It never bothered me personally, nor did I ever feel that the game developers were trying to shove a message in my face. It didn't feel forced.

So besides that, one important thing to note is that this game has dialogue options and multiple endings. Different outcomes will happen depending on what dialogue options you've chosen. You can choose to be really nice, neutral, or an asshole to everybody. These will all affect the ending later. So the game has replay value in that regard, which is nice. There are also some branching paths in which you can do things in a certain order, or do one thing instead of another. I got... an alright ending? I was nice to everyone but I made some incorrect choices in some areas, so I got the second best ending I would say.

So now that you know all this, is the story good? Yes, honestly! It has lots of twists and turns, the dialogue is pretty good. There's mystery, murder, drama, tension, big reveals, all the good stuff a visual novel/point and click game needs. It's also pretty funny and made me laugh more than once. (Let's just say spoiled milk is the best item ever.)

However, I did have a few small gripes with the story and characters (and no this had nothing to do with their identity or sexuality) First, the story could have been paced a little bit better. There's a lot of... "Busy work" where a character wont do something for you unless you go on some kind of fetch quest for them, or help them with some kind of problem. The story basically just halts here whenever that happens, and it started to annoy me near the end. Sometimes in my reviews, I say that some of these indie games could be longer. This game is actually pretty long, especially for the price (about 10 hours) but it could have been trimmed down in a way that would have benefited the story.

Next, I take issues with Jess, a "Hybrid" character who has the appearance of a cat. This did not bother me, rather her attitude towards the protagonist. Basically, when you meet, you are given dialogue options, and you can choose to be an asshole and make a bunch of cat puns, essentially mocking her. She gets justifiably angry with you for doing so.

But I DID NOT do this, and Jess was STILL angry at me for no reason, she began saying "all you care about is making fun of me," or "you dont care about Hybrids or our identity" when I NEVER DID ANYTHING OF THE SORT. This seems more like a development oversight, like you were expected to be rude to her, but I wasent.. I literally picked every single nice option. so it made Jess seem more like a jerk than anything else. I didnt like her character because of this.. They later explain why she has this attitude, but this shouldnt have happened in the first place if I was never rude to her.

Don't miscounted my issue with Jess to the other characters. They are all interesting and have lots of little quirks that make them funny, or unique. I especially liked Turing, and some other characters (more on why later.)

The worst character, however, is YOU, The protagonist. You are a pretty blank slate if i'm being honest: And I understand why: they wanted to create a character that could identify as any gender (or no gender) so they had to write them in a way to make it super open ended. However, you are the least interesting character in the whole game, and you're more of an observer to the events around you. A part of me wonders if Turing should have been the main character...

Those are really my only major gripes with the story. It's a good narrative, it's a good length, it has lots of mystery and narrative grip, and tons of replay value.

GAMEPLAY:


This is a point and click adventure game where you navigate screens and click on objects. You can interact with the object in many ways, such as using an item on it, interacting with it directly, or speaking to it (which usually does nothing.) You will encounter many puzzles, in which you must use items or pick the correct dialogue to complete it. For the most part, the game is pretty easy: it's clear what you're suppose to do most of the time and it never felt convoluted.

There are some puzzles that have a random generator to it. For example: there's one at the end of the game involving a maze. So it will be different for every player. This is cool, but it's a timed mission, where if you mess up, you have to try again from the beginning. This feels... Unfair, because it's random, and you have no control over how the maze is layed out. However, for the most part it is streamlined and to the point.

As I mentioned earlier, different decisions in dialogue will result in different outcomes. a character may be less willing to help you if you are mean to them. Decisions matter in this game, which is nice.

I don't really have too much to say otherwise on gameplay, because it's pretty simple. Some of the controls for unique sections (like in the maze) can be confusing because the game dosent tell you what button does what, but for the most part it is easy to pick up and play! If you are a fan of older point and click adventure games, or TellTale games (more on that later) you might like this one!

VISUALS, AUDIO, ETC


This is the look and feel of the game. 2064 has a pixelated style to it (which you can see from screenshots) LOTS of Indie games do this, but it works for this one. It compliments the Cyber Punk setting very well. The animations, while limited, are good. Character models are expressive and detailed. The environments look great! Good mix of colors and building structure.

The music is also pretty great, it's atmospheric and well composed. The sound in general is very nice, there's a lot of different effects and things to hear.

I want to highlight the voice acting in particular. If any of you have played Telltale games you might recognize some of the voice actors, mostly from "Walking Dead," such as Melissa Hutchison, who played Clementine, or Adam Harrington, who played Bigby Wolf in "Wolf Among Us"

There are also several Youtubers who lend their voices to this game. NateWantstoBattle, ProZD, and Jim Sterling, among a few others, can be heard voicing the characters. This game did not initially have voice acting, but the Switch version is an updated title to the game that includes it. You can turn off voice acting if you want. Oh, before I forget, in terms of the game on Switch, it crashed on me once randomly, but otherwise I had zero issues in terms of the port.

My only gripe with the voice acting, because mostly everyone does a great job, is the direction on some characters like Lexi. Lexi has a good voice actress, but the way she says her lines is... off. I don't think she was given clear direction on what she was saying. There's a few characters like that. Otherwise, everyone does a good job, both from the professional actors and Youtbers. Nate in particular was pretty funny.

Uhhh what else... There are extras you can view. Concept art, trailers, music, etc. Which is nice.

Annnd I think that's all I have to say:

FINAL THOUGHTS

This was a pretty good game. For 3 bucks, it's a really good deal, especially considering the replay value and content given. The story was really good and I enjoyed it a lot. I liked most of the characters. It looked great, it sounded great, it has replay value... There's a lot to like here. If anything I said interests you, check this game out!

FINAL SCORE: 7/10

[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.

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. Possibly a Ph.D. Then apply for my position when I retire. Check here for how to apply at ESA: https://www.esa.int/About_Us/Careers_at_ESA/Frequently_asked_questions2#HR1
How much is too much? DVK: 42 again
Are you aware of any asteroids that are theoretically within our reach, or will be within our reach at some point, that are carrying a large quantity of shungite? If you're not aware, shungite is like a 2 billion year old like, rock stone that protects against frequencies and unwanted frequencies that may be traveling in the air. I bought a whole bunch of the stuff. Put them around the la casa. Little pyramids, stuff like that. DVK: If I remember my geology properly, Shungite forms in water sedimental deposits. This requires liquid water, i.e. a larger planet. So I don't think there is a high chance to see that on asteroids.
