NASA Spacecraft Returns Extraterrestial Material To Earth. Scaring Scientists During Landing
HTML-код
- Опубликовано: 24 сен 2023
- NASA's OSIRIS REx spacecraft completed its primary mission by returning a large sample from the asteroid Bennu to Earth over the weekend, dropping its sample return capsule neatly onto a test range in Utah after giving the engineers some concern that it might crash.
Now the material has been recovered it'll be sent to labs to be analyzed using technologies and instrumentation which could never fly on a spacecraft.
Meanwhile the parent spacecraft is renamed OSIRIS APEX and is headed toward a rendezvous with Apophis.

do you ever ponder how mad it is that 100 years ago we flew about in biplanes and zeppelins and now we can land on an *asteroid*, get a sample and fly it back? It's mad....
Yep. I hope there's many more wonders to witness in my lifetime.
it's actually a major concern of mine and source of hope. it's ridiculous how quickly things are changing, but that's exponential growth for you. a long time of consistence slow growth, then boom, late game exponential change.
I hope that in the next 100 years flying into space will be as normal as taking an airplane. And hopefully the medicine will have gotten good enough that I'll be there to see it
Not FAST ENOUGH I say!
@@ai_serf Lets hope the game is not yet so "late". We need speed and longevity improvements.
In keeping with the theme of over-performance: it landed right next to a road! How much easier can recovery get?!
It was nice enough not to land directly on the road.
Still, they used an helicopter XD
Crashing throught the roof and landing perfectly on the pedestal
The recovery team came in via helicopter. Probably muttered "darn, we paid for a helicopter when a truck would have done"
Wasn’t this how The Andromeda Strain started?
The company I work for made the PICA for Osiris Rex's heatshield. We made the heatshield for Stardust (and multiple Mars landers), too. Last year we made the PICA for the upcoming Dragonfly mission and we are currently making the PICA for the Mars Entry System of the Mars Sample Return mission. The project I am working on is for the Earth Entry System's heatshield for the Mars Sample Return mission. It will be made of a material related to PICA called 3MDCP. Very exciting times!!!!
PICA=phenolic infused carbon ablator. Machined some of SpaceX's version. OMFG the dust from that stuff. 3MDCP=3D mid density carbon phenolic. Had to look this one up.
Your company may very well had been partly responsible for a man-made cataclysm. Maybe it's time to audit your company with the white glove treatment.
@@JoshuaBerner what?
I read PICA in pikachu voice every time, I don’t even like Pokémon.
I’ll see you in my office tomorrow morning!
I helped build, test, and launch the first of these Sample Return Capsules when I helped build Stardust. It was the same design and likely built in the same clean room. That capsule is in the Smithsonian Air and Space Museum in DC with my signature inside it.
I see they got the G-sensor in the correct orientation this time (Unlike Genesis)
I also helped build Genesis, so I could explain the entire failure if desired.
We "believed" that IF the drogue chute did NOT deploy as designed that the capsule might be destroyed if it began tumbling too early in the entry phase. Apparently, the drogue is not required as both this one and Genesis survived the most challenging part of reentry without one.
That’s amazing that you got to work with this!
Nicely done. Even the best engineered craft will have glitches like this. In the military we would describe this as "No plan survives contact with the enemy". Reason you have to over engineer and have contigency plans. Good job on this one :).
I've been to that part of the Utah desert when we had FireX in 1988. Used to hunt geodes and Amethyst crystals around there before that. Pretty barren place perfect for a landing place for these craft.
yes please @@stuartgray5877
The part about the parachute being stored in space for 7 years is something I simply didn't think about and is something to admire the material scientists and mission planners for. The foresight you have to have for such a project is absolutely insane.
Think about the BATTERY that had to withstand being stored for 7 years. It is a primary battery (cannot be recharged). If it goes dead during the mission, the capsule is toast.
@@stuartgray5877 What kind of battery was it? Radioisotopic generator?
@@andreasu.3546 - "What kind of battery was it?" Its been a while but I believe it was a Lithium Phosphate Primary Battery. It was the kind you have to short out before use to burn away the "passivation layer" that protects the charge for all those years in space.
Fun fact: Reserve parachutes in sport skydiving rigs should be repacked every half year/one year, becouse there may be anaerobic bacteria growing in there and in worst case they damage the fabric or make it sticky, so it doesn't open.
@@tomeknowicki8603 Even anaerobic bacterial don't do well in a vacuum. At least as a skydiver you don't have to worry about embrittlement or vacuum welding
I recall some of the material collected jammed the container door due to its loose nature and it flying everywhere. They had to risk opening and closing it again in the hope of dislodging it despite risking losing too much material. Fortunately they succeeded. Can’t wait to hear results.
If anyone is interested the WB57 high altitude plane is based on the English Electric Canberra which first flew in 1949.....from a time before the first artificial satellite, before the first man in space, right up until today, when pieces of a meteor is returned to earth, a Canberra has been flying high....& its still going strong. It really is quite amazing.
Yeah, those things are fantastic... a first-generation jet bomber designed towards the end of WW2, but still in operational service nearly eighty years later, employed to monitor vehicles travelling to and from other worlds.

I believe it is the last B57 airframe that is still airworthy.
The public documentation of this is underrated, well done nasa. Science for all!
On Sunday, the UK's Channel 4 News ran a great interview with Sir Brian May - the Queen guitarist and astrophysicist - about his involvement in the stereo cameras used by Osiris Rex. Being a very cool person, he was just as enthusiastic about the space mission as he was about practicing for his upcoming US tour.
Thank you. There was surprisingly little coverage of this today. To me this is a huge deal and the teams that worked on this deserver a LOT more credit.
I want a documentary on the clean room procedures and design of the isolation equipment built into the probe.
It's called "The Andromeda Strain"
I'm waiting for the Real Engineering video on it. It seems right up his alley.
Do you work for Roscosmos?
@@darkstar8925"There's a fire, sir."
Was about to comment the same :)@@darkstar8925
It almost breaks my brain to think that someone would have been building this thing, watched it take off, waited for it to visit an asteroid and now just gets to open the same container up again. And this is somehow where we all live now.
those are all different ppl, except for the watching part.
Wow thats impressive as hell that the return vehicle could intercept earth, then rocket off for a second destination. What kind of engines are those?
He said slingshot towards, my guess is it uses the forces from that to accelerate mostly.
The thrusters/boosters used were most likely just to get it into the right flightpath to make use if this slingshot effect. Quite interesting and i'm totally not qualified to explain it so i'd look it up :)
Yes, it mostly would have used gravity, with thrusters to get in position.
The main craft never entered Earth orbit, it simply dropped off the sample craft, on the way by...
rocket engines
If you want to really understand how that works play KSP. Nothing teaches orbits and interplanetary trajectories like doing it yourself. 😊
35G's - that's a stroke out for any little critters on board...
I remember the launch, the taking of the sample, and now got to see it back to Earth. WOW!
It's been awhile since I've seen one of your space news videos. They are both awesome and accessible to ordinary, non-aerospace/astronomy/etc major people/experts. 10/10 NASA, good and cool mission
In KSP I had trouble landing even on the correct side of Kerbin let alone so close to the target. Impressive!
KSP does rocket science backwards- most routes start planning at the landing zone and then everything is timed backwards from there ending at t-0.
@@actually5004I wouldn’t necessarily say that, at least when you’re building a vessel it starts you off with the final stage of the ship, whether it be a lander or a return capsule
@@alexsiemers7898 To be fair the "planning" that I'm referring to doesn't happen at all in KSP for most players, whether you start from the VAB or already have something in LKO ready to shoot off.
This changes with transfer window planner and kerbal alarm clock, sprinkle in some algebra regarding the period, angle, and sidereal day and hitting a target isn't too challenging anymore. I do like Squad's top-down approach to rocket engineering though.
Boffins at NASA have better slide-rulers and sometimes toss Napier bones for good luck. :)
NASA has access to military grade mechjeb.
I rewatched the re-entry a couple of times to see if I had just missed the drogue chute. I initially came to the conclusion that it was just too small to resolve on the video stream, but now I’m thinking you’re right that it didn’t deploy at all. If so, it’s a good thing the main chute had some extra performance margin at hand!
I am a Special Equipment Operator (SEO) for the WB-57. We operate the camera aboard the aircraft in his case. We just installed Starlink for this downlink. Hope everyone enjoyed it. let me know if you have any questions.
How is the camera able to track such a small object like that? Does it use radar or is it some other method?
Huh... a nearly eighty-year-old aircraft design, paired with the latest in communications tech. That's pretty cool.
What was the distance between the aircraft and the spacecraft?
@@MScotty90 The camera is loaded with the nominal trajectory. The operator updated it with inputs through a joystick. They never follow the nominal path so there is always some manual input.
@@h.dejong2531 Closest point of approach was planned for 5 Nautical Miles.

it never ceases to amuse me how we spend all of this time and money on discovering and understanding our place in the universe, and most of the time, it boils down to "hey, check out this cool rock I found!"

Some of humanities biggest moment have been finding a use for certain rocks.
Our maior periods are even described using kinds of rock.

I made history yesterday
@@aq_ua Agreed. the Genesis capsule (I also helped build) returned solar wind particles.
I was commenting on how this *sample return capsule* technology has been used before. This event has a lot of heritage.
I think it’s even the case that the majority of the samples are archived for the time being so that we can continue research with new hypotheses and instruments in the future. That is a brilliant idea and very impressive thinking ahead.
I’m very happy that the mission went so smooth and that we have this amazing opportunity to have this material now on the planet to study it thoroughly💪
There isnt much more that we can advance for stuyding samples, except to make the equipment less exepensive and bulky and a little bit of more resolution for MRI's.
Heck if you are able to save up a few grand you can buy an microscope that will scan right down to the atomic level. And it fits on your desktop.
Same is done with archaeological finds. A lot of sites are covered back up and preserved, simply because the tech or funding isn't there to give it justice.
Just like the Moon rocks.

After you had explained your private situation over these days I didn’t expect you putting out this video so quickly! Thx a lot, well done as always 👏👏👏
What happened ?
@@fridaycaliforniaa236 he had talked about some private things going on right over this weekend
@@fridaycaliforniaa236death in the family IIRC.
The OSIRIS REx mission reminds me so much of the Scoop mission from Michael Crichton's Andromeda Strain. Seeing the retrieval team pick up the return capsule (which might not be closed properly) without bunny suits or even respirators was shocking! 😦
“The OSIRIS-REx sample return is classified as an unrestricted Earth-return so there don’t need to be any protocols put in place from a public safety and Planetary Protection perspective,” said Nick Benardini, Planetary Protection officer. “Due to this type of target body having only some of the key formational and evolutionary organic molecules necessary for life, there is no chance that the sample from Bennu could contain living organisms.”
Thank you Mr. Manley for the prompt video about the sample return mission.
Greetings from the UK

Absolutely amazed by this mission. Imagine sending something far in space, years in advance, land on a pile of dirt rapidly moving in space, get a bunch of it, detach, drive back to Earth and land safely... It's absolutely astonishing!
"the world's most expensive baked potato" You always get a chuckle out of me, thank you for covering this and showing the footage of opening I hadn't seen yet.
Great mission summary, Scott. In the closing moments of your video, looking at the Osiris-Rex return vessel, knowing it was sent out seven years before returning to home, collecting samples; flexing our collective skills in mathematics, engineering, computing, rocketry, chemistry, etc. etc..... it is an amazing time to be alive! Your channel is fantastic. Thank you!
Scott, Thanks for the fullr report and excellent video and commentary. Great job.
I had the same reaction while watching the descent yesterday, I could not see the drogue chute. The speed the capsule was going when the main chute did deploy must have been higher than planned so it will be interesting to see how that handled it. I'm not sure why they've had issues with chutes twice now but I hope they figure it out.
Good report Scott. Yes, I was wondering how having the parachute deploy early could make it land three minutes early.
I wonder if the drogue ripped off when it deployed. That would explain how the main managed to deploy.
Thanks for the awesome Bennu images! Likely missed your narration on those parts. Fascinating images.
i was just waiting for your commentary Scott....amazing as always
Just like in KSP, drogues are an optional extra you don't actually HAVE to include. 🙂
Just to be on the safe side, I would like to say "Hello and welcome to Earth" to our new Andromeda Strain overlords. 🙂 Seriously - can't wait to see if the data from this small sample will actually be indicative of the composition of the larger asteroid.
I was thinking about a protomolecule. 🤔
The “science” of The Expanse can’t hold a candle to that of The Andromeda Strain. I say that as a fan of both.
@@RJNoeIndeed. I would say the only 'science fiction' of the Andromeda Strain was the organism itself. Everything else was science fact, and state of the art for the late '60s. That's what made it so powerful.
Hello new space virus pandemic
Amazing mission. I was there from the start, remembering launch, sample gathering, and now return. Now, waiting for results, and the Aphophis encounter. Super cool mission.
The re-entry story was quite the cliffhanger, wrapped up as only you can do. Another great one, Scott.
I was watching the stream and heard them call out drogue deploy and how it was under it and i was jumping up and down shouting there's no effing drogue! Massive relief when main deployed, i presumed i just couldn't see drogue as too small for camera.
that would be my assumtion too.
Maybe the drogue was too small at the camera distamce to see as well?
Gag me with a spoon!
An amazing mission. it landed about 2 hours away from my house. Absolutely crazy how well this mission has gone despite all the things that happened.
Scott, fascinating, thanks for sharing!
Fantastically descriptive footage, Scott! THANKS!!! Couldn't wait to see what's inside there! Way better than an Easter Egg, to see the mineral components they find and what conclusions could be made upon that!
Would be interesting to see an episode on Nasa’s WB57 since the Martin Canberra has been going since 1953!
So actually in this case, the 'pics' were taken from a Canberra...
Not bad for an originally British design from the late 40s :P
I am an SEO (sensor operator) for the WB-57. She is a great bird.
@@nanunanu83 How are you able to keep these flying? Spares must have become a real problem.
@@h.dejong2531 We have an excellent maintenance and engineering team. There were 21 F models made and we have scavenged what we can from the boneyard and museums. We refurbish or remanufacture a lot of parts.. Some things were just unsustainable. In that case we design integrations from current aircraft. For example we have F-15 Strike Eagle landing gear because we couldn't get tires.
The time from main chute deployment to touch down was about 4m50s. The speed under the main chute I found somewhere given as 11mph = 4.9m/s. That gives a good estimate of the main chute deployment altitude of 1420m or 4510 feet as the capsule descended for 290s under the chute. Pretty close to the given design spec of 5000ft. The main chute being able to function safely even without prior drogue chute deployment I guess was a built in redundancy.
Redundancy is built into every space system so yes, it was absolutely redundancy since you wouldn’t send somebody to space without built-in redundancy system.
NASA claims both chutes deployed
Thx for your hard work with your channel. The content is always informative.
Thanks, Scott!
Wouldn't it be funny if we found tardigrades in the samples.

Excellent summary, cheers Scott.
Just remembered what a cracking film The Andromeda Strain was.
Is the President ready to execute Directive 7-12?
came here looking for a reference to this scenario, thanks for not letting me down :)
I watched this 'live' and was wondering about the lack of visible drogue parachute..be great to know if that was planned for etc
perhspd because it got more samples than expected, the lander was heavier and thus had to deploy the drogue chute latter in the ascent when the speed was lower?
Scott that was poetic science easily digested but still complex in scope. Can’t wait for the composition findings!
First long term mission I have followed from start to end. 😊 can't wait to see the science
I find it even more interesting when I was born nothing had left earths atmosphere. Shortly after I was born, the Russians put up a satellite. All it did was go beep, beep, beep, beep, beep, beep. Then people started flying faster than the speed of sound. Men landing on the moon. Remote controlled vehicles landing on Mars. In my lifetime people will be on Mars, I’m sure of it.
Thanks Scott! I was looking forward to your commentary on this one. I’ve not seen a single mention of it in mainstream media, which is frustratingly sad.
Indeed, the only place besides other space news, was stupid conspiracy and celebrity news you find as click bait at the scum sucking bottom ads that are so poorly written. Well the last scene showed what looked like a crustacean with a bunch of leads attached to it.
Thank you for the video. I was just interested to see about the return of the capsule after the news. which I somehow missed at the moment when it landed )
I've compared the camera image at 9:27 of your video to google map of the landing zone, and I think the capsule landed at the coordinates 40°22'20.0"N 113°14'23.6"W
I am an SEO for the WB-57. At 57:23 of the official feed you can see that we enabled the ground intersection point display in the bottom right corner. You can see the coordinates there.
Is that the longest a parachute has been in space and then used?
I think not. Cassini mission was launched on 15th Oct 1997, and Huygens probe touched down on Titan 15th Jan 2005, which is 7 years and 3 months roughly. Osiris Rex launched 8th September 2016, and touched down 23rd September 2023, which is almost exactly 7 years. So by my calculations, not quite the longest. These are all google dates, so they may be wrong.
Great video, as always, thanks Scott. I think it's really cool this thing got back to the surface intact. Hope they get some good science out of it. What's even cooler is they're now sending the mothership back out to another body for more science. Mapping surfaces and other imaging activities, I'd presume. Good stuff!!
Great explanation Scott. Thanks!
I couldn't help but think of monster films and video games where people are in a clean room opening a space craft or something and then the monster pops out and gobbles them up.

Very interesting video. I got a glimpse of the Stardust re-entry about 15 years ago. It was just a brief line flash on the night sky. I was 30 miles South of San Francisco, looking North. It's nice to here NASA's Canberra (WB-57) was put to good use. It was sitting in a hanger near my office at the Ames Research Center in 2003, after developing hydraulic problems on a flight from Hawaii. It was only there for a couple of weeks.
Psyche is launching on the 5th! 🥳
I put notes on my calendar years ago both for the encounter with benu & the sample return. What a successful mission! So excited for science that'll come up from this.
An excellent explination of the misson, cheers!
Thanks Scott. That was a hell of a mission, Mars Sample Return has a tough act to follow! Exciting times.
Gag me with a spoon!
Thanks Scott. Will you do a follow up on the findings of the recovered material? A little out of scope for you channel, but very interesting to follow this up.
Very, very cool. Looking forward to all the papers that will come from this set of samples
Hey, Scott, if OSIRIS-REx was a dinosaur what kind would it be?
Maybe an ostrich.
I’d love to know the engineering that went in to directing the capsule from release during a fly by to a landing in a known area.
The basics of it are pretty simple for being obnoxiously complicated math. It was a ballistic trajectory. Know your location and velocity, and make sure that that line will intersect with Utah at 8:52 am.
How do they know location and velocity? I saw an article about a radio telescope RADARing it in the days before, and correction burns being made. Know distance and direction from a known point on the ground and you know where the spaceship is. Do this a few times and you can do distance/time to find velocity.
Once you sort through the orbital and rotational reference frames, of the spacecraft, the telescopes, and of Utah, it's just an intersection problem.
It came in from a pretty steep angle too, so aerodynamics don't have all *that* much effect on the landing zone like happens with a low earth orbit reentry.

They're amazing... counting the original English Electric version, they're probably the only operational jet aircraft that's been around longer than the B-52...
It's not often that things go significantly wrong, but it all works out anyway. I was only watching the stream on the side, so I was wondering why I couldn't see anything resembling a drogue chute. I guess we'll find out the details soon.
Let's appreciate the cameraman who shot the footage from launch to asteroid touchdown and back to earth. Cameraman can go any distant in space and never dies. 😂
Great video Scott.

If you’re curious, yes the asteroid Apophis is named after the character from Stargate SG1! However, the name Anubis would be more apt because Anubis in the show launched an asteroid to hit and destroy earth.
Lol officially? I suppose you can name stuff in astronomy about anything so that's fine. Usually if they want to name something after a TV character that's named after a historical deity or figure, they just feign ignorance and say it's named for the original and not the pop culture character.
Works for NASA equipment too, everyone knows Enterprise was named for the Star Trek spaceship, but they could only justify it by agreeing to pretend that it's named after the real life historical ships named Enterprise. =)
"Carter, I can see my house"
Indeed...
No. The asteroid is so dark that they named it after Apep, AKA Apophis. en.wikipedia.org/wiki/Apep
They're obviously saving "Anubis" to name the one that _will_ hit Earth when they find it.
Apophis is just a practice run.
thank you Scott!
I love how they find the meteorites on the ice sheets. That must be fun looking for them out there.
Very interesting video. Just out of interest, since the sample was exposed to about 30g deceleration which might have bashed up the contents a bit, I wonder how feasible it would have been to have the sample capsule rendezvous with the ISS and then get returned to earth on a human rated space craft?
IT would be impossible.... as a start, you need fuel to brake without the atmosphere. A lot of fuel. In fact, in this case, possibly more fuel than was used to send the spacecraft to its destination once in earth orbit. (The initial fuel +/- all extra needed to supplement the energy gained or lost fromt he flybys )
@@framegrace1 Ya that makes sense, I guess it would be impossible.
I have said for years, NASA should land a probe on Apophis so they can get PIN point accurate orbit info.

Very cool! I hope we learn a lot of unexpected things from the samples.
If anyone has any evidence of a whirling, twirling, hurling, hurtling, wibbling, wobbling, zipping and zooming, spinning space ball, spherical "planet earth", I'd sure like to see it.
Our observations leads to it. You think people came up with this from nothing? LOL. But people today probably don't even watch the sky and probably would not have notice the planets, while already in ancient times people discovered them.
And what are you talking about whurling, twirling, hurling, wibbling,...? Do you know how copernicus came to the heliocentric model? He observed that the planets make weird trajectories and loops at the skies and change their speed. So that would be hurling and wobbling and that would be strange. So he thought: What of not the sun and the planets move around the earth, but instead the sun is fixed and the earth and the planets orbit around the sun? Because then the movements suddenly make sense, and they are clean ellipses around the sun.

Great video, I'm looking forward to the results 😄
Now earth’s gravity has been increased by the mass of the return sample. That explains why I don’t feel like working outside. Hehe
Nice video I was kinda wondering the same being far from an expert it was seemingly missing that drogue chute, and I relaly feared it would just crash when the camera was ging down and glitched out.
Glad that in the end the return was a success.
You explain things better than anyone else❤
The drogue chute is first to stabilize the attitude of the falling capsule and second to assist in deploying the main parachute. There may have been a secondary main chute deployment system or the drogue finally inflated enough to do it's job. Maybe both. As far as slightly faster decent speed; it wouldn't have any appreciable effect on the main parachute. The terminal velocity of the capsule was likely less than the terminal velocity of a skydiver as it was lighter than a human and that main parachute was quite large.
