Wait so the japanese space agency spent billions to retrieve samples from the asteroid and because they got alot more than expected they just handed them out to other agencies for free? Thats actually so awesome
I know someone who will be working on one next week, I’m so excited for him!
Awesome, thank you Japan.
❤️🇯🇵🗾 Why can't we all be more like Japan? Let's say just the last 70 years.. or 19th century & prior. Go! No.. The game, the oldest board game eva!
NASA gave many Moon rocks to various nations around the world as gifts. Unfortunately many of them have since gone missing.
The Japanese agency is big on cooperation
You bring the level of discovery down to the masses in simpler terms. Thank you.
This episode was really well done. Brilliant!
Wow! Go Jaxa! Go Japan!
You just reached out, grabbed a bit of an asteroid and brought it back to Earth!
That's pretty cool!
AND, Jaxa has Done this TWICE!
I've seen enough horror movies to know this will all end in tears
@@rogerwilco1777 I have seen you in several movies holding the sign 'Rapture is coming' 🤣
@@rogerwilco1777 'I was just a child when I heard the the elsers calling it the Hayabusa hell..' In cinemas only...
Thankyou for another wonderful video Anton 👍
Can't wait to see what can be learned from the Osiris Rex return-sample mission of Bennue.
I can wait , for the samples to return , 🙏🙂
I learn something new everyday from you Anton. Thanks for what you do.
Always look forward to your videos. Thanks 👍
Hope you're doing well Anton
Thank you, Anton, for yet another video making it easy to understand these amazing discoveries! Also, I wanted to say how heartening it is to see how great the fundraiser is doing...so many children will be helped in Neil's memory! I hope you always keep the the earthrise segment at the end of your videos, because I always think of your young son waving back to his awesome dad and family. Warmest regards to you and yours, Wonderful Person!🥰
I love the work you do and share on RUclips. thanks sir
I love your content thank you for being here
We can hope this is only a start because getting samples from asteroids or comets is so much easier logistically than getting samples from planets.
Japan is very poor in mineral resources. Hence the interest in asteroids.
@@holycow666 I think human expansion into space will only really start when we use asteroid mining, so I like that it makes some progress
Thank you for this and so many other educational lectures. Of course you make it so easy to learn. Never a dull moment. And on top of that you've set up a grand donation port. It is a pleasure!
Keep the Love
Peace on Earth,
Freddy Chavré of Maple Valley
Been waiting for this update, thank you so much!
Thank you Anton. I hope you and yours are doing okay
exploring comets and asteroids is the key to the future of space exploration and colonization. No need to drag large amounts of material with you if you can simply stop by the local cometary "7-11" and load up.
Actually, its the opposite way. Its absolutely impractical to bring stuff mined in space back to surface of the Earth and vise verse bringing raw materials into a space.
Thinking of you today, Anton. Sending your family my love and my strength.
What I love is how they got extra material and then scientists around the world can inspect the material in a worldwide team. It makes it to where we can do more in depth studies and get the data far quicker.
This is my favorite new idea. It seems to make so much sense.
That was such an excellent piece I can't even express my thanks.
Thank you Anton for making this wonderful episode , You always take me to a place I’ve never been !
As usual, another wonderful & interesting vid. All the best Anton!
That’s so neat. Thanks Anton! Great stuff as always.
We love you wonderful Anton!
Another amazing and interesting vid from a wonderful person 😀
That picture is Bennu
Edit: Ryugu looks almost like Bennu from it's rhombus shape
thank you Anton much respect
I completely enjoy listening to you speak Anton.
Hi anton , karlos here daily visitor to the worlds most wonderful RUclips channel 😀 ❤ 😊
Thank you for working so hard to bring us this kind of information every day. ❤❤
Wonderful as always anton 😋👍

Thank you wonderful Anton
Oh... An ex comet? That's brilliant! 😮
I hope you're doing ok you wonderful person, thank you for another great video.
Stunning science & professional presentation.
Love your vids.
Interesting and perplexing, thanks Anton
Congratulations , JAXA , re the successful mission .
Looking forward to the analysis reports findings .
Interesting video! Thanks Dr. Petrov. The "end" of many comets maybe. Fascinating.
Thank you Anton. 😊
So if a comet has a close-ish and stable orbit around the Sun for 4 billion years, this is what happens. Basically what happens to my bacon when I over cook it.
Well done for your fundraiser.
Excellent Vid 👍
5 Grams of Comet Dust, does this mean they get 5 wishes?
Thank you so much for taking the time to make this knowledge accessible to every day people. Fascinating universe we share, isn't it 🙂

Thanks Anton.
Love the subtle background music 😎
The first thing I noticed was, this "spinning top" is a similar shape as a natural diamond
Well given C type asteroids share the chemical isotopic ratios of comets so we already knew they share a common origin it is more of a question of when the degassing occurred and whether the object has been reprocessed in collisions. This seems to point to a much more recent degassing event, quite fascinating really.
I really like this explanation.. maybe if an asteroid meets certain minimum criteria to fit this theory - their names could be updated to include a famous ballet dancer - because of the way they increase spin - and there's something extra beautiful about an asteroid being a retired comet 🤩
Ice dancer who got smacked with her partner’s skate. Or the hockey goalie whose throat got slashed.
@@edwardgatey8301 i mean yeah exactly right? asteroids are known to wreak havoc sometimes.
Just for fun it looks like an old Borg Cube.

Thank you 🙏
A “C” class as in carbonashiuos. Ie graphite. I think. I’ve been finding them all over our dry lake area here in the high plains Nevada. And it seems all ages of all types. Strewn with volcanic agates and such. Still looking for that iron meteorite for my collection. But here I would request Anton, could explain more about impact diamonds and polycrystals. Please!!!!
Excelent video!
The regolith could be used as concrete and structures built (3d printed)where you can walk on the ceiling due to the artificial gravity.
It would be an awsome observation post in space.
Amazing
I need good news like this today
God bless you and your whole family.
Great video again wonderful person! Strange, I've loved solar system geology for years and never considered what would happen to a comet that got captured in a long term near earth or inner solar system orbit. It seems kind of obvious in hindsight 😑
@Anton Petrov Hello I am a new visitor to your channel and want to say I love the content. Do you have any videos that explain why our moon does not rotate 🤔?
Weird I thought last year Anton pumped out a video but apparently I'm not able to find it. I hope you get correspondence. Be well.
Our moon *does* rotate but it is tidally locked to Earth so it rotates at the same rate as it orbits, once every 29ish days, hence we only see one face of it
Might it also mean that this asteroid could be easily tunneled into to create a shielding habitat for people who want to travel between Earth and Mars? In fact, is the rotation sufficient to create an artificial gravity in an interior compartment?
Nice comment on the gravitational field aspect, notice how the shadowing arc may only be 16% and I think that's more than the moon has if the shadowing arc is greater on the moon means less gravity. I'm referencing the disturbance as takeoff happens
At 5 minutes 44 seconds, if I remember correctly but it's been a good 10 years the planned resolve if one were to do this was it needs to have a full body net. If enough material was gathered and put together one could create a wired fence type net. Due to applied instability from inhabitants it would need to have a stability structure due to shifting.
I might be wrong though it's been a good decade .
Except the accretion part of two distinct masses, that is how I envisioned what these close up images show, they sublimate down to the rocks. Just because it is not out-gassing now doesn't change it into an 'asteroid'. Just watch parking lot snow piles melt to a pile of debris. I still think there is more mass than fluffy snowballs to swing great distances from the Sun and pulled back the way they do. In other words a dog bone shape is the sublimation results of a single progenitor.
I agree. Too much substance. I thought...flying coral?
A chunk of something like the white cliffs of dover.
And it kinda has the classic Carbon shape... Diamond.
Thoughts?
@@HoneyBadger80886 I readily see what your driving at, naw, probably something weird like the octagon (?) at the poles of Saturn (?) My thoughts are Platinum and other heavy metals along with chondrites lurking inside.
@@bardmadsen6956 yes. I see.
It’s a kingsford charcoal briquette that escaped 5 billion years ago!
Yes hayabusa the most complex ever made, Great thx
Nice
I suppose even comets have to retire at some time.
Yes
Intriguing
Merci.
These could represent the comet that hit the earth and we have water idea Seemed very interesting because of that
Japan knows how to share space knowledge. Take note other countries.
China also shared its moon-rock samples recently.
Semantics. Everything out there is space debris. A combination of this or that. Human space travel is the direction we should be persuing, and i don't mean the glorified airplane (ISS) in low earth orbit.
2:57. The way those rocks and gravel were flying around was interesting. Low gravity makes it look like confetti.
Whats more interesting is that those pebbles did fall back to a surface and didnt bounce away.
LETS GO TURDO 🇨🇦
The shape of that spinning image kind of reminds me of a jewel.
Antov I would love to have a drink with you Buddy....👍👍👍 Your awesome🤘🤘🤘
makes sense
Hi Anton, thanks for all of the videos.
When you said “organics” what does that mean ?
IIRC, it means molecules containing carbon, oxygen, nitrogen and/or ummm i want to say hydrogen but that's clearly wrong...
(carbon + hydrogen) based compounds are called organic.
Amino acid molecules
Thanks everyone
@@Barnaclebeard According to "Soluble Organic Compounds in Asteroid 162173 RYUGYU" one of the samples contained 3,76% C, 1.14% H and 0.16% N (by weight). Since H is a lot lighter than C, there were more atoms of H than C in the sample
Thank you Anton, I watch your video every single day.
Victor Klube and Bill Napier proposed this way back in 1984
Presumably closer orbit of the sun by a comet increases its rate of sublimation thus reducing its mass & making its orbit more susceptible to perturbation by other astral bodies, which in turn could potentially alter the track of its next orbit?
I am supposing that rotation shown is actually sped up a good bit. Such a low mass object would be tossing those bolders off the surface.
@@user-kz8ik8wd9g I am going to assume that my comment would not impel the real Anton Petrov to presume I needed investment advice.
We need more research on how music effects health
I agree. Although mainstream outlets and "experts" claim that the music and media you consume has no impact on your physical and mental heath it's quite obvious to those with eyes wide open that media and music is a weapon. Thank you for bringing this important topic up. Keep it up, Osmosis Jones.
Quite off topic from the video but I agree
@@Psych_Ward it's a bot
@@top10jesus10 you will never get a reply
First, love your videos
Im surprised the Japanese did this. I think its pretty awesome I'm impressed🧚♂️
I think you might be confused about the sample collector. Hayabusa II fired an impact impactor into the asteroid to expose a surface which was fresh. It then descended to the crater and collected material. I think you'll find that the video of the sample collection was sped up. I believe that the scattering rocks were caused by Hayabusa accelerating away from the asteroid. They wanted to get away quickly due to the risk of damage to the spacecraft. Hayabusa 1 and 2 have also done pioneering work with ion propulsion. JAXA has achieved a great deal on what is a shoestring budget compared to NASA or ESA.
Fascinating Anton! We can be quite impressive when working together.
The Human Race I mean.....
sounds good to me
So sorry to hear about your child.
good! one more time japan makes me happy for their innovation....
maybe one day comets will be our next generation gaz-station ^^
When a rubble pile is exposed to heat and Vacuum the sublimation rate is advanced many times over and leaves a debris trail like our Aquarides later in the winter. But first it needs much deeper sun plunges.
I was expecting you to do a brief comparison to the Osiris Rex mission to the asteroid Bennu. It's also a rubble-pile, NEA with the same shape, rapid rotation and a density of ~1.2 g/m3. The shape seems to be caused by the rapid rotation pulling everything outward against its feeble gravity (since there's nothing else holding it together).

I wish science news were a little more exciting to the commom people, like myself. I mean, I'm expecting the announcement of alien life proof, a new Earth in a reachable zone, the discovery of gold on the moon, time travel, stuff like that... instead we have "huge discovery on Mars: The atmosphere is 2,9 % nytrogen, not 2,8 % like we previously thought." xD
Naice
cool

The shape is like a dreidel 🤭♥️
