Asteroid Bennu’s Surprising Surface Revealed by NASA Spacecraft
Вставка
- Опубліковано 6 лип 2022
- Near-Earth asteroid Bennu is a rubble pile of rocks and boulders left over from the formation of the solar system. On October 20, 2020, NASA’s OSIRIS-REx spacecraft briefly touched down on Bennu and collected a sample for return to Earth. During this “TAG event,” the spacecraft’s arm sank far deeper into the asteroid than expected, confirming that Bennu’s surface is incredibly weak. Now, scientists have used data from OSIRIS-REx to revisit the TAG event and better understand how Bennu’s loose upper layers are held together.

I imagine you could mine an asteroid like this with nothing more than a vacuum
I don't know if it was intentional but I see what you did there 😂
Space is essentially a vacuum already.
@@stevenbisaillon7321 lol. Very astute
Ha ha ha ha you are a special person aren't you? Of-course you are.
That idea sucks. 😄
OSIRIS-REx spacecraft was truly groundbreaking...
Haha!
I see what you did there....
Aaaaaah haha👉🏼👉🏼
I know right
Yea. It was pretty awesome!
It's amazing that these asteroids can hold together at all.
No it isn't.
Amazing “scientists” did not take into account static surface charge. Cohesion is practically irrelevant without an earth ground and without humidity.
Just physics!
Not that amazing, its just sort of what happens - now if it got his by another asteroid it would be a huge mess.
You can do whatever you want with a computer. Any cartoons.
I wonder how much material was put into orbit around Bennu and how much escaped.
I'd imagine none of it was put into orbit, you could probably reach escape velocity by jumping, since it has very little gravity
Depends how much you want. They can paint anything in Photoshop

@@NJ-rn7wu He means his peabrain can’t fathom how people with fancy learning can accomplish things he can’t, so he comforts himself by imagining it’s all faked.
@@stephendatgmail that makes sense.
Nice to hear ones name mentioned so many times
You're a cool guy, Benno!
Bennu size: 565 x 535 x 508 m, Mass: 7.33e10 kg, closest distance from Earth: 482,120 km.
Correction: - Mass 7.33e10 kg - 250 g...

Space will always remain fascinating...thank you NASA
So fascinating!!!
So basically it’s just a massive dust bunny. 😊
I think not. It has a quite definite overall shape.
With something dense enough to attract dust
Interesting video! And what an archievement for this crew from NASA! Nice to see how an operation like this exactly works. Thanks for sharing!😀
Simply amazing. Thank you for posting this documentary.
What an amazing feat!!
Liquid rock asteroids, awesome. Wonder how long it'll take this little nugget of info finds its way into a sci fi movie.
Thanks! It's great to see videos about real space exploration.
Bet you believe in Santa?
@@weseehowcommiegoogleis3770 Bet you're fun at parties
Hmmm….define “real”
A charcoal briquet impresses you?
Bet you think Biden really got 81 million votes too huh???
Not one (1) person with a degree in maths, physics, chemistry deny space. Only bums do.
@NASA Goddard, Great videos and explanations to us amateur science enthusiasts
ROFL..you mean sheeple!!!
Someday you'll be a professional science enthusiast
@@pjcouture9944 Dullard
@@SalvableRuin real scienxe maybe!!
You are cartoons enthusiasts 😂😂😂 you have no idea about scince and what actually it means.
So if Bennu were to hit earth, it'll most likely collapse into very small pieces in atmosphere and disintegrate. Unless its inner core is like a solid metal. If.
or will it?
You called?
No chance, its massive, no matter what breaks off it will still cause catastrophe
I would have guessed electrostatic attraction would dominate over gravity as a binding force. Can any experts chip in with a ratio of forces? Well done team.
Nice comment. That seems very logical. Hope to read some responses.
You are, of course, absolutely correct
electro static would be localized attraction where as gravity accumulates with more mass
Gravity is not a force.
Source and why?
Excellent subject and coverage!
This stuff never ceases to amaze me. To infinity and beyond!!!
To a physiological cell with padding 👍
Buzz Lightyear's just as real, too! 🤣
@@maxlove4906Well Dahhh. Why else would there be a movie about him?
This discovery will definitely reshape future asteroid missions and probe designs
great visualisations!
this was a really compelling video thank you
So does this change some of our understanding of asteroids and our ability to break up or "redirect" one headed towards earth?
Fantastic new information, analysis, and animation!
An outstanding and fascinating mission thank you for sharing this
Excellent work!
Imagine if that gentle tag ends up diverting its orbit to eventually hit earth someday? Good times.
Or if we find its valuable enough to mine into nothingness...
Thanks NASA! That's some truly interesting information.
Disinformation*
Fascinating video. Thank you very much for sharing it with us.... we all enjoyed it.
Bennu is certainly a strange object!
Not at all
So is it possible that many asteroids are not a solid rock, but actually just a bunch of rocks, pebbles, and dust?
And prolly ice or frozen gases.
Kinds like a loosely packed snow ball?
Maybe because things appear different to 77 year old parts (me) but that is not what I would have termed a "soft" touch down. Would have probably jarred me enough to fall. Inertia.
it was shown at 17 times speed
Jarred you ??? Really!…..

Great genius work of science and aerospace technology!
Just incredible
You're right... it is wholly incredible!!
How fast was Osiris rex coming in when it contacted Benu? It's bonkers that it would move 6 tons of material from what looks like a slow approach.
It's approach and touch-down velocity was mentioned as 10 cm/s. That equates to about 0.22 miles per hour. A normal human walking pace is about 3.5 miles per hour (or 156.5 cm/s). So - pretty darn slow.
Good question
10cm/second - average walking pace of an insect
3:25 Someone wasn't listening 🤦♂️
@@tonyp2632 pardon my ADHD :o)
Absolutely incredible 🇿🇦
Howzit!
it’s amazing just being able to see a real video of that wow
That's not a real video, lol.....
I'm sorry... at 0:46 there are some real images.
@@TieDyeVikki they are about 1-2 seconds apart kinda like a gif! I guess we’re both right a bit lol
Yes, thanks for this interesting information. Erich from New Zealand
Thank you.... life affirming stuff when all around seems so benighted.
Fascinating. Thank you.
Interesting. Well presented. Thanks for good stuff.
Pretty cool indeed.
I can't wait!
Nice explained
So it's basically a cluster of granola. When you touch it, crumbs fly everywhere!
Excellent channel thank you good stuff..🕵️🧐👍✨...😎
thank you !!!
Incredible & Stunning.
That is so cool.
absolutely amazing!
that is amazing animation!
Awesome 👍
This was an amazing accomplishment
I loved this video, so well done, thank you.
Feels like science fiction but it’s real. Amazing! What a feat of engineering and maths.
well, being that this video is just an artist rendering, it may be
@@BatMan-co1gy you mean it’s not real? A bit like you then?
That's a heck of a STEM creation.
very cool mission
I would be a little scared to "hit a bigger chunk" and getting no material at all
That was awesome. Thanks
All we need is for someone to construct a giant vacuum cleaner. Spaceballs, anyone?
Very cool!👍👌
Was it just me or did that Asteroid look like a charcoal briquette? What a interesting video.
That's really cool. Thankyou
we are monitoring this situation
Imagine seeing that asteroid and expecting any sort of surface cohesion.
its just a huge bundle of sand and boulders
That dirt ain't cheap!
Amazing, thanks! We just never know anything for certain until we see it for ourselves. Take Pluto as another example!
this video is just an artist rendering, sooo
@@BatMan-co1gy At 0:46 there are some real images.
Wow this is so awesome!
Wow!!
Super infor!
Coming back this fall!
NOVA had an episode devoted to this mission.
Thank you. 😎👍
There may have been a electrical discharge as well.
Good one - thx
Exciting!!!
Now they just need to find a golden asteroid.
I wonder if this would make mining it to remove its collision risk with earth would be worth it or what its value as a mineral source would be...
Amazing!
Go NASA !
Beautiful
bennu politely say get out of my area
Amazing.
that is so freaking cool
Good. Harry Stamper and team will make quick work of drilling to 800 ft.
Wow!
This is so amazing! Wow!
This 600meter astroid might be cool to see
Would that facilitate asteroid mining ? maybe we just need some kind of gas blower and a hoover thing to collect materials
Bennu is getting Medicare and a gang of robo calls for extended auto warranty
We love science!
That popcorn looks good!
worthy of star trek model making !
Expectation: frozen solid interstellar rock
Result: ball pit softness
lolol
Ar you sure it's name isn't "Kingsford".
How are you,
My name is Kulith Kethaka. I am 14 years old. My school is Siri Piyarathana Central College and I am Sri Lankan. I like astronomy very much. What tests are you doing these days?
Can you please send me some details and pictures about it?
So effin cool 😱
WOW……6 TONS???😮
Mining these things for resources in situ wouldn’t even require a drill, just a trowel and a bucket.
When you think about it it’s really mind boggling
That is so cool interesting
