Tour of Asteroid Bennu
Вставка
- Опубліковано 16 чер 2024
- When NASA’s OSIRIS-REx spacecraft arrived at asteroid Bennu in December 2018, its close-up images confirmed what mission planners had predicted nearly two decades before: Bennu is made of loose material weakly clumped together by gravity, and shaped like a spinning top. This major validation, however, was accompanied by a major surprise. Scientists had expected Bennu’s surface to consist of fine-grained material like a sandy beach, but were instead greeted by a rugged world littered with boulders - the size of cars, the size of houses, the size of football fields. Now, thanks to laser altimetry data and high-resolution imagery from OSIRIS-REx, we can take a tour of Bennu’s remarkable terrain.

Basically, what we have here is a giant heap of gravel held together by its own gravity.
Yeah, pretty much.
Basically planets then?
@@user-lp7tx1fe6t no It doesn’t have a star to go around like our sun and it is not a round shape so it is a astroid
But it’s S P A C E G R A V E L
*Critical Thinking alarm! @@user-ce7og4ct6p Ahem ... _Bennu is in SOL's System, and Orbits our Sun.*_
I learned more about fictional mythology than I did facts about Bennu.
100%
Um. Aren’t myths fictional by definition?
@@jasonwillis7345 Not necessarily. It is widely used in a negative connotation. But its main meaning is simply a traditional story.
AGREE
Very true
You need to put a dude next to those boulders for scale cause these 70' boulders look like tiny rocks
Pebbles
Great idea!
I'll go! I'll go!
[jumps up and down frantically]
Pick me! Pick me!
Just visualize a 20' long Suburban parked next to them...
Imagine a building with 7 storey's.
exactly what i was thinking.
Seems more like a tour of ancient myths.
Which has no need for tour. Reality not only exists, but also is necessary.
Religion, superstition, astrology, are *all* anti-science, overtly or not. There's enough of that out there already.
rightt
yeah it made me not to watch this video and stopped it. No interest in that ancient bullchit.
@@jimbarchuk “Science without religion is lame, religion without science is blind.” Albert Einstein
More geology, less mythology.
Agreed, even though I understand them trying to create a 'human connection' with it.
But if that is what they are trying to do, why didn't they mention how 'rock 'n' roll' it is?
@@tsopmocful1958 What's wrong with geology AND mythology ?
Agree... I love mythology, but I came here for geology.
Agree
3:35 That Benben Saxum, protruding at just 70 ft, was actually detected from Earth, is absolutely amazing. Wow.
Even orbiting such a small body is an impressive feat, let alone collecting and returning samples from it.
Yes, billions and billions spent while they claim they can't afford to issue a second round of stimulus checks and want to cut it down. Ditch NASA, ditch foreign aid and let's take care of AMERICANS first!
@@HobbyOrganist yes lets do that, and leave our progress as it is now forever until we are all wiped out, massive forward thinking logic 11/10
It still astounds me how far we’ve come as a human species and yet how primitive our base emotions sometimes are. Amazing stuff NASA as usual....
Very interesting observation and very true!
It's our ability to trust reason over emotion that lets us do that.
Technology makes us look smarter than we actually are.
@@hdgboy Another great comment and true!
@@MelindaGreen سلام
Thats amazing, obviously. A survey with this level of detail is quite impressive. Would love a 3D resin model!
That will happen
maybe 1.000.000.000 of polygons... better a small version. ;D
MonkeyspankOsmokysmoka
I'd like to have a 3D model of Earth.
@@fatelamore With so much detail it contains a tiny version of you holding his own tiny 3d model that also contains a tiny version of you holding....
Any chance you could nudge that asteroid our way? Might be a swell way to finish off 2020.
oi vey
@Dave Smith woah....slow down, north Korea is a better option
I was just thinking about this as well
@Dave Smith I was thinking more like Washington DC.....lol
Lol this thread of comments is hilarious 😅
I would have liked a scientific explanation rather than a mythological explanation!
"It is a rock made up of different materials flying through space." doesn't capture attention I guess.
it's kinda like a rock. There.
Absolutely amazing. Thank you so much for making this!
I just earned 1 college credit in ancient mythology.
🤣
Very well done, team! And a very welcome excursion.
Very cool! Thank you for posting this!
Nice video but to much story and to little science.... also please enable Metric system
but america only uses 'football fields'
@@daos3300 And Rhode Island units.
Criticizes NASA's use of imperial, yet can't spell *too* properly. . . interesting.
@@chrispridemore5562 I don't see how those are related
NASA uses metric for all it's science and engineering, but uses Imperial because... yknow it's an American space agency right?
Incredible coverage. Thanks!
*Love this kind of stuff,*
*Thanks for sharing with us.*
I think it's kinda cool that Bennu's gravitational acceleration is 0.00009807 m/s² vs Earth being 9.807 m/s² (nearly).
Very easy to fall off.
That is an interesting coincidence.
You could jump and be sent flying into space like superman
We humans love patterns
Nerdy, but interesting.
Nasa flexing their naming skills.
Well, what names would you suggest?
@@mfjdv2020 I'm not being sarcastic.
Would have been nice to have a banana for scale (or a person)
Here you go 🍌
Person in a banana suit would be perfect
Nah a coke can is better
i'd rather see a plastic bag, would be quite fitting for humans
Chevy Suburban. 20' long, easy to visualize parked next to a 70' rock...
Wonderful fly over...just amazing
How about making this into a feature length film that's two and a half hours. They could name every single Rock and Pebble and talk about some mythology behind it.
/End sarcasm
Only two and a half hours? I'd watch way more than two and a half hours of that.
/End sarcasm
Seriously, were we looking at a asteroid video, or a lesson in ancient mythology?
Why not both ?
Mythology or science?
@Goran Vukovic They're also trying to educate people like you. As we can see, sometimes it doesn't work.
Great report. Thanks.
very cool. giving dimensions and adding a human for scale was a nice touch.
Thanks, wonderful video! But NASA, can you use standard measurements, please?
C'mon, as tall as a skyscraper, how more precise do you want?
@@BornAgainCynic0086 (1) Not all countries have skyscrapers (2) Skyscrapers come in different sizes. They can only be an approximation.
Whoa, enough name explanations! More data instead please...but superb mission views.
A really beautiful video.
NASA: I wonder what that asteroid is made of.
Everyone else: Um, rocks?
debris
Absolutely stunning
Poor lonely rock drifting in cold space :(
Great pictures and exciting commentary: deep impression.
This video is more about mythology than geology 🤣
This is so solid. I didn't know we were still getting this quality analysis from NASA.
What?
No Little Prince?
Hey, that's pretty rad. 😎
It’s a rock millions of miles away; but apparently it’s packed with birds, harpies, elephants, and gargoyles.
Fascinating. Thank you
I can't wait to use this information!
As a gold prospector... I will tell you this asteroid looks like a giant conglomerate. Crush it up, run it through a sluice box, no telling what interesting things you would find.
Y mite just take a peik
With all this technology we humans still couldn't find an missing 777 jetliner in our own earth surface.
this kind of explanation about asteroid rock..it is rockgasm to my ear..yeah rock en roll.. nice🤘
Thanks!
CBS New York showed clip about this and immediately came to Nasa info to get more info. Amazing stuff.
This is so cool!
Truly amazing!
Mind blowing that we can see this
Wannabe asteroid mining companies: Write that down, write that down...
Seems like space mining is still a century or more away. There are some huge challenges.
@@dewfall56 It maybe closer than you think. Space mining has tremendous cost, but even better profits without any laws that would hinder profiteering.
They're gonna have to figure out how to tame that fast rotation first.
@@dsnodgrass4843 cannot agree more 👍
Fantastic to see. Was that created with photogrammetry whilst orbiting?
Rather laser distance measure
Was hoping for a walking tour to get an idea of scale. Thanks though.
Liked and subscribed!
Im glad to witness this space rock exploration 😊
"She blinded me with....Mythology?!"
Nice space conglomerate, thanks.
This is amazing
It is amazing to see Bennu but more amazing we can actually go there... I agree with KAOS a scientific explanation would have been awesome.
i thought i saw my old alternator from my 1968 mustang, i knew it went somewhere.
That is some funny stuff, Jody!
Beautiful detail! Amazing stuff.
Man has shown its advancement in science. Proud of humanity.
Could you share this video as 8k 3D? What graphics engine do you use to make this visualizations NASA? Many, many people would love to experience this with VR goggles.
They have had 50 years to try colour film, how about we start there? It's not grainy or blurred, but it's still B+W.
Facinating.
Fascinating!
Awesome. Now I'll watch a video about ancient mythology so I can learn more about asteroids.
Looks like if you sneezed, it would turn into a billion pebbles.
Thank you.
That is a nice boulder.
Never thought that rocks can become this much important.
Can't wait until Amazon builds a distribution warehouse there
I would love to see an average person next to each of these features for reference
incredible
Very nice
In appearance, this is a very, very, very old asteroid. Is how long it takes for so many small stones to stick to it.
If only that were how they’re created. They can’t get pebbles to stick together in space, much less an entire asteroid. Accretion doesn’t work. It’s all electric. Electric Universe.
@@helpdeskjnp Yes, probably you are right... Electric charge...
This Video rocks!
It's 16.5 football fields in length and weighs only 2 cranberries... astonishing!!
How soon until I can plug in an Oculus and virtually tour interplanetary surfaces?
This is so cool. Thanks, NASA!
Breathtaking🙃
So no vibranium??
Rest In Peace Neil Armstrong,You Made History.
Wonderful 👍
interesting tour
Fascinating
NASA is a science organization, why are Imperial measurement units used, rather than SI units?
Yes!!
Exactly my thought!
I think it's just for people to understand. They are trying to communicate this information to others after all.
Something stinks
How about it's relative speed to earth? And what is it's gravity power?
It varies.
Wiki it..
Bear Down, team!
I had hoped a little prince would show up.
A banana for scale would have been nice. There's no reference.
Sky scraper. Which can be many a banana
too much myth not enough science and I am not talking about this meteoric impact nonsense either, fantastic data though
Nothing wrong with myths.
@@redcat9436 is that a metaphor as well!?
Thanks to NASA for sharing that stunning video! I've learned a lot and with pleasure.
It should be quite possible to appreciate both science and greek mythology.
Ya, less mythology
any photos?
First up I learned that it has low thermal inertia. Fascinating. What is thermal inertia? I have no idea.
Just looks like a sticky ball collecting bits of stone as it travels through space.
What I would have LOVED is a human for size comparison. That's be even more fascinating!!
BenBen is about 11 humans tall.
@@iGame3D thank you, kind stranger
Sooo cool!
WAIT THIS LOOKS LIKE A ROCK CUZ CAMERA MAN GO BRRRRRRR
Is there a 3D model of Bennu with such a detailed surface?
Interesting graphical construct, most edifying. Thanks for posting.
What are you, a Vulcan?
@ Somebody with a better comprehension of a more extensive vocabulary than yours.
@@JoeOutdoors "a better comprehension of a more extensive vocabulary"? I would stick to 'cool beans' if I were you 🤣🤣🤣
I'm just wondering if there is a a specific mass at which an irregularly shaped asteroids like Bennu becomes spherical in shape as in planets or moons?
