Landing On Mars Like You've Never Seen It Before
HTML-код
- Опубликовано: 29 май 2024
- Perseverance had 6 engineering cameras on it which were active during descent and landing to document the process in more detail than we'd ever seen before. The engineers had never seen their skycrane at work before since it was impossible to test on Earth.
In the end only 5 of the cameras worked, and the microphone failed to record anything during the descent. But the results are still spectacular!

Sky Crane: Fly safe
Scott Manley: Fly to victory
Sky Crane: wait what?
.....
It crashed minutes after successful deployment of its payload, as planned
Too bad it wasn't planned to land softly.
MY MANWICH!!
That's the moment when the sky crane realized there were in fact no other sky cranes behind the dune to help it land and it had been lied to.
when scott manley no longer says "fly safe" you know shit got real
dare to fly riskily
Fly... safely away from Percy, please
more like go become trash elsewhere :D
He didn't say "fly safe" because sky crane is meant to crash
Exactly, CzlowiekImadlo. There's no safety for the sky crane, but at least we can wish it a glorious passage to Valhalla.
Actually it just went off to rust somewhere.
Perseverance: "Tango Delta"
*Detaching Cables*
Skycrane: *Commencing YEET*
I respect this comment. 🤣🤣🤣
I wouldn't be surprised if the name of the fly away program was indeed YEET. To make it official they usually attach a very fake backronym to it, like Your External cranE Termination
Makes me think of that scene with the tow cables in Empire Strikes Back.
They should name the next Skycrane after the gunner flying with Wedge Antilles that shot the cable at the ATAT.
Decoding..."They sent me to Mars, and all I got was this lousy parachute."
Everyone at Ames who spent hours upon hours on the world's largest supersonic parachute: "Am I a joke to you?"
These videos are like getting a guide in a museum. If you want you could just walk around and see the exhibits, but having a guide makes everything so much more interesting.
Actually just seeing a real sky of another planet is just mind-blowing to me.
@Johnny Silverhand he said ‘another planet’ bruh 😐
I hope they send something to Venus again and we get to see more pictures from there
@@anonpls9909 I don't think we would see much in Venus weather
Agreed, there's something special about a foreign horizon.
Aqeel Raja I’m guessing Johnny is a flat earther. Complete with requisite misspelling.
This has got to be one of the most mindblowing piece of photography ever done in space science/exploration
It makes the idea of boots on the ground all the more real again.
@@-danR Or, arguably, irrelevant and/or quaintly obsolete. ;-)
agree 100%. Just amazing. Seeing the descent stage hovering was just the coolest thing ever.
better win a pulitzer
The most mindblowing thing about it is that it took over 20 years of landing rovers on mars before they got around to sticking on a couple of "throwaway" camera modules to let the engineers evaluate their landing method, instead of just getting "it worked" or "it didn't work" as a feedback. At least Curiosity could have had all those cameras - it may have made less sense with the "bouncy castle" landing method of the twins in 2004.
The fact that it is the real footage and not CGI is so surreal!
We have entered the 'post-truth' age of exploration.
Yeah sure it is. Just like the moon landing lol /s
And how could you possibly tell that from this video you puppet
@@TinyMoMosWorld Oh man you must be so woke. Tell me more about the flat earth, George Bush and 9/11.

"Rover rolling 10 hours"
Hopefully without that high pitched tone.

@@ccarson NASA already split the two up on the press conference lol
i knew i'm not the only one thought of this haha
The breakdown of the Mars landing I’ve eagerly been waiting on!
my channel has the title of most viewed video.
I haven’t really seen it until Scott Manley shows me all the stuff I missed.
If you want a better breakdown and some in-depth discussions, be sure to watch the live stream that NASA did on Monday where they revealed all these images.
From above it's hard to tell if its 10,000 meters or 10 meters off the ground.
Yes I thought that too.
Nothing familiar for our eyes to get scale from.
ikr. Even though I roughly now the distances from further out, like what the radius of the landing site was, how far apart these craters are, it's just so hard if not impossible for me to grasp how far away they were in each situation. Yeah they call it on the radio but it's just so hard to comprehend
The mission paradox, The Parachute let them down, the Sky-crane let them down, yet the landing was successful.
Gravity let them down, but the Parachute and the Sky-crane held them aloft long enough to save them.
Atlas gonna give you up, Parachute gonna let you down, Skycrane gonna fly around and desert you.
I believe something like that is NASAs internal moto.
Of course, just like the rick astley paradox
Niether the parachute let them down nor the sky crane the both did their job as expected the paradox is in your head that is incapable of comprending the science behind it.
I refused to watch the other videos with this footage because I wanted an excited Scottish man to describe stuff about it to me!
Definitely everyone here
same
I watched Astrums short and left a dislike because it was vertical video. Then I waited for a proper video. Thanks Scott.
@@georgf9279 Thank you for supporting the eradication of vertical video.
I need an excited Scott to commentate on the NFL Super Bowl to explain what's going on... would make the 4 hours fly by! 😁
I didn't notice a lot of the things you mentioned in the videos... that's why ur videos are worth the wait
Yes, I saw the same videos yesterday but got a lot more out of them now.
I heard it was a successful landing and immediately thought "Cool, I'll just wait for Scott to post video with commentary on all the good bits for in depth coverage of the landing."
Manley-rich explanation.
Not to take anything away from Scott’s cogent-as-usual coverage, but if you’d watched the JPL press briefing yesterday morning, you’d have learned all those things - except for the decoding of the parachute riddle! The JPL mission leaders discussed them in detail, and I’m sure Scott himself tuned in to listen before he did his video. What I’m really curious about is whether Scott figured out the parachute code himself, or had ‘inside information’ thru his contacts at JPL... Decoding it wasn’t trivial, or so it seems to me. ;-)
@@claudiusdunclius2045
Did they explain the hydrazine exhaust visual paradox?
Scott does a much better job editing and presenting NASA's raw footage of the Perseverance descent and landing than any other I have seen. Thank you Scott Manley.
This is a good start to the year. Vision of the landing is incredible. The parachute opening while travelling faster than a rifle bullet. The deliberate positioning for the landing and the lowering down from the sky crane. You can imagine the tension on the JPL team leading up to this moment. What an epic achievement.
"What matters is the amount of thrust, not the amount of fire and flame and spectacle."
You really had me going there, Scott. For a few years I thought you knew what you were talking about.
eh?
@@Jesse__H I think it's a joke
So if I forget my phone charger, there is Finally an extra USB port on Mars. 🙏
Mark watney will be able to plug into it without having to rewire anything
Just don't forget to bring adapter to the latest usb-mini-micro-cxyz your telephone uses
Or maybe there’s an extra one in the Tesla Roadster
and it's powered by an RTG...i wonder how many times you can charge your phone with it
@@frommeslaemmchen Well, based on my recent views & reading this RTG is rated at 110W electric output at launch day.
Fuel is pellets of Plutonium-238 with a 74 year 1/2 life (I recalled) vs bomb or reactor grade Pu-239 of 24,000 year 1/2 life, so much greater heat released per day.
Assuming a constant linear system output drop over time, it may have 55W output in 74 years, maybe 25W in 150 years, 12W in 225 years? I seriously doubt your cellphone will last that long.😆😆
Hopefully it will be still powering an adjoining educational display at the Marsopolis children's museum by then! 🤔
They should hire Scott for NASAs PR department. This is so much more informative and entertaining than the official channels...
SkyCrane flying away playing DARE . . . "Don't . . . Don't you want me"

The sky crane just booking it after it successfully dropped the rover is the coolest thing I've seen in a while.
That is a job well done.
Yeah it was fucking cool mate
Same here, the whole operation is really impressive but when it cut the cables and flew away i lost it, looks so freaking cool!
Where are the cables cut? Next to the rover or next to the sky crane?
And if they're cut next to the crane, would that mean having the Perserverance Rover dragging the cables around every time it drives along the Martian surface?
@@davidharrison7014 they are cut by the rover, you can actually see the cut on one of the early pictures.

@@InventorZahran haha well looking at the parachute code, all I saw were the "shagged" possibilities, but I used a program for the rest :)
@mug wump nice ones, plus "mighty threading" is so appropriate for the parachute!
Grind meaty thighs. Yess. Ofc
Hearing the wind on another planet is just so amazing
Huygens also had a microphone and recorded titans wind.
I know. Hearing that over the mechanical sound was just... yea. I don't have words.

Hey, listen up down there! That thing is called an elevator, not a bathroom!
Hope we don't here that hum from the movie Mission to Mars, otherwise a giant tornado will spin the rover to death.

ayy
B E S U R E TO D R I N K Y O U R O V A L T I N E
@@MichaelOnines killroy was here
It would be wrong for a parachute to say, "Never gonna let you down"
But the chute did let them down!
Idea for next video: How will the thin Mars atmosphere effect the sound that is picked up by the microphones ? ( pitch, volume, etc )
10:40 Scott explains the code like it's nothing and my head explodes!
yeah, it didnt look very intuitive imo.
11:01
Scott: And the direction becomes obvious.
Me: What the heck is ERAD ?
E-RAD: electronic radiation
Or I just might be hight too
E, rad stuff bro :)
Maybe it's a word scramble? We need to READ!
According to Wikipedia, ERAD is Endoplasmic-reticulum-associated protein degradation.
"Who is LEON?"
The mic mechanically didn’t fail during EDL. The recording just didn’t happen because of some software error. They fixed it and the mic was used to capture that wind gust
As the Manly Scot himself quipped on Twitter, the computer handling microphone input was running Linux, so of course it had audio issues.
I'm glad I didn't write that piece of software
Yet the first working microphone on another planet was during one of the Soviet Venera missions on Venus.
You can hear banging and the loud drilling into the Venusian soil onboard.
@Game Over Nope. While Perseverance's main computers run specialized operating systems, the DSU, a specialized computer-on-module which collects and processes all the EDL data (the six cameras and one microphone), runs Linux.
@@trimeta They just runned alsamixer and then everything was fine.
Scott - pretty sure they showed two different cameras angles, not one, for the parachute opening, as you can tell by the shadows on the cables and position of the sun.
And the markings on the chute are rotated in the two different views...
@@Jon1010 yeah it’s really clear that it’s 2 angles
yup the parachute is 2 diff angles and i swear i wathed the nasa press conf. were they played the sounds from the microphone as it came down.
They indeed said during the press conference that there were 3 chute look up cameras, but only 2 of them worked, one failed. So, they probably showed us both views.
@@wulf2121 Yes - I was just pointing out that Scott said there was only one view (at the start of the video)
I think the gentleman who once said [long before there was a JPL] “Far better, to dare mighty things....” would have loved watching this.
“And that was better than any touch down in the Super Bowl”
Didn’t know physicists could flex that much 💪🏻.
It's really unnecessary and just comes off as a pseudo-intellectual "I'm too smart for sportsball" statement.

@@liberty0758 What's your best evidence this is fake?
Whenever something happens in space flight, my first question is how long until the Scott Manley video.
America does it again! GOD BLESS AMERICA!!!
Next Mars Rover, let’s add a speaker 🔈 to play La Cucaracha as it drives around.
Speaker is a great idea, how does the Mars atmosphere affect the known sounds it plays.
Better play Slim Whitman's "Indian Love Call". You know, in case of ACK ACK ACK.
If you're going to have a speaker on a rover on Mars, the rover must be named Rick Roller, and the speaker must play "Never Gonna Give You Up".
I also like how at ~5:29 and at ~6:27 we can see Perseverance lower the back wheels to prepare for landing.
This is amazing, As a person working for KSP once said..: Making History.
I feel so very fortunate to be able to watch this.
5:48 "And that was better than any TouchDown in the SuperBowl!"
It was also 100% more TouchDowns than the KC Chiefs got too!
You might want to double-check that maths.
@@Kyrelel Sure, let's do it together...
Perseverance touched down 1 time on Mars.
KC Chiefs did not even get 1 touchdown in SuperBowl 55.

Scott - It's a very simple code
Me - *can't figure it out*
I figured it was binary code but didn't know it was formatted that way
It looked like binary to me, but I was too lazy to pause the video and try
Thanks for being brave enough to admit that. I thought about alphabet positions in binary, but what threw me off was the 7 bits per letter when 5 would suffice. It's only "simple" once it's pointed out to you. Plus there are large chunks that don't represent anything except the orientation of the chute (I think). Still pretty cool, though.
@@johnrex5342 Cool, thanks

Thanks for decoding the parachute! Nice to see them having fun...
"Thanks for flying us, Sky Crane! Fly... to victory!" Haha!
9:30 While I'm sure you're right that the skycrane doesn't have much in the way of guidance, at the press conference they pointed out that it can't just shoot off in any direction (or straight up), it needs to specifically pitch either north or south so that the thrusters (with their 1000º exhausts) are never pointed directly at the rover.
This is an excellent opportunity to make a pun confusing thermal degrees with arc degrees, but I can't think of one :/
Right. I think at the presser they said the rover is pointed to the southeast. The skycrane departed to the northwest, as you can see in the annotated MRO image at 1:02.
I always say out loud with you, “Fly Safe!” But, this time you fooled me! 🤣

"The real science will start to soon." Love ya, man.
this was too awesome...
a VIDEO from mars?!?!?
wow
I really though the sky was going to be darker and more orange, but now I realize that Mars’ color comes from the soil and unless there is a huge dust storm, it would look quite similar to earths. It’s really cool!
I think that's not correct to be fair. It looks blue because of the dust the rockets blew up. When it settles i think it will be a lot more orange
The color balance in these images is, as Scott said, all over the place. But the air usually seems to be dusty and thin enough that it's some shade of tan most of the time, dominated by dust rather than Rayleigh scattering. The sky color does vary a lot. I think the blue that Scott mentioned in the images looking up at the sky crane is from Mie scattering, which is by dust particles but very small ones, like smoke.
Thank You Scott. Whenever something significant happens in space exploration, it’s not complete until you cover it. 👍🏻
I absolutely love the newest and greatest cameras in space. I grew up seeing old fuzzy (sometimes b&w) shots of various men walking on the moon, and it disconnects me from the concept. But now with these beautifully full color 4k shots, it seems a lot more real. I love seeing SpaceX's live video from inside the faring during separation, I love seeing the skycrane gently lowering Perseverance to the Martian ground, and I love seeing astronauts during a space walk outside the ISS. The reality of it is much more potent, like I can experience it myself if I were there.
that parachute deployment is one of the most beautiful things I've ever seen - if I'd seen on earth it wouldn't a big deal BUT having work so smoothly @ 132.52 million miles away.. sigh.. PERFECTION
Good ending Scott, yes that sky crane deserves a lot of recognition. It’s a beautiful machine that served a noble purpose.

Best thing to happen this year so far , keep it coming JPL and NASA!
Mars is a beautifully quiet place. I can imagine standing there and just listening to the wind blow by.
You'd probably start losing your mind though after a couple hours, from sensory deprivation
I don't know, being able to appreciate and enjoy the stark beauty of things like that, the emptyness of a desert, the dead of winter, it has an appeal.
If you were standing there, you would be in a spacesuit. If you were in a spacesuit you would not only hear the wind but feel it as well. If, as is likely to happen, the high-velocity particles would tear into your suit, so you could smell and taste it as well.
As you would also have a visor, and could see the wind patterns, you would have experienced the wind with all 5 senses. Not what I would call "sensory deprivation"
Zoom-classes just aren't cutting it :/
@@Kyrelel
What are you talking about bro? You wouldn't hear anything inside the helmet, except your own breathing. There are no sounds of nature, and you would barely feel any wind at all. Mars has only 2 percent of earth's atmosphere. And there are no high velocity particles that you would feel
I watched the NASA video thinking Scott Manley wil analyse the crap out off it!
Thanks for gathering this all together. It makes my life easier.
Gorgeous, the sound was the best part.

Nice one Scott! Thank YOu for that illuminating narrated video of the 2021 Mars landing of the Perseverance Rover, and its Skycrane maneuver.
Such a great start!! Those scientist at NASA and JPL are just awesome!
Anyone else feel sorry for sky crane? Once its successfully completed its mission, it was just ordered to "bugger off and die"....
Or heat shield or the orbital component that stayed behind.
My thought (and feel) exactly. Why not have it arc safely away and when it's a safe distance off (maybe a four-second acceleration burn), go into "try to set down any old place" mode. Even if it runs out of fuel too high and belly-flops hard, it won't vaporize and leave a crater like it would at re-entry velocity. And it's more likely to keep the wreckage in one limited area, easier to salvage it in the future (most likely for the alloys and maybe the wiring harness). Plus it's another experiment: did the sky crane manage a close-approach landing? At what point did it fail? How dry can you run those hydrazine tanks when actually performing in Martian gravity/atmosphere?
Maybe next time...
Absolutely amazing to hear the wind ON MARS!!! Fantastic, informative video. Thanks very much.

Great podcast, thank you Scott!
Quite possibly the most amazing video I have seen.
last time i was this early you woke up at 2 Am to tell us about how SN4 exploded
If you’re interested, it’d be really cool to see how the rover manages to operate on just over 100w of power
The RTG generates 100w-ish, but it actually still charges batteries on board for things that require peak power in excess of 100W.
Isn't the waste heat from the rtg used to keep components from freezing? That must be a huge saving not to run electric heaters as previous solar powered rovers had to.
@@yumazster Exactly my thought process, if Spirit & Opportunity rovers had been equipped with even undersized (vs total power budget) RTGs to provide basic heating plus some bonus electric power, they may still be doing some useful science data transmissions, even if only as weather stations!
Their successful missions may have pushed up the confidence level for follow up rovers investment$$ and survivability tho!
Another excellent video Scott thanks!
One of the better videos, with explanations, thanks!
