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.
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.
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.
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.
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.
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."
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. ;-)
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.
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.
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.
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.
"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.
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
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.
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
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?

You know it’s a good video when you’re inspired to run to the white board to prepare a new lesson for math class tomorrow. Learning binary, math mystery, and Mars 2020?!? Let’s go!
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!
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.
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.

@@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 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.

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.

“Dare mighty things” comes from an 1899 speech by Theodore Roosevelt. "Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to rank with those poor spirits who neither enjoy nor suffer much, because they live in the gray twilight that knows not victory nor defeat." The speech also reflected the American spirit at the turn of the 20th century. The increasing industrialization and urbanization of America led many to become fearful of growing weak. College sports were on the rise, as were recreational athletics such as bicycling. American culture embraced masculinity, patriotism, and nationalism Issues of masculinity were especially predominant during this time, given the various women's movements of the age. Critics and scholars, including author Henry James, worried about a femininization of America. The time was ripe for Roosevelt to extol the masculine virtues of the strenuous life. Roosevelt used the speech to justify American imperialism as well. Well fancy that...!! 🙂
You say that there was one camera at 75 fps during the parachute sequence, but the left and right images are obviously from different points of view, hence different cameras! (Look at the orientation of the stripes in the parachute, and direction of the sun)
Yeah, but later he mentions that there's another camera connected via USB3 to the rover. So I think he meant that only _one_ of the 75fps cameras was working, and wasn't counting the 30fps camera.
@@hjalfi There were 6 EDL cameras attached over USB in total. 3 looking up at the parachute at 75fps, one down from the sky crane to the rover, one from the rover up towards the skycrane, and one looking down towards the surface from the rover. I believe the real-time speed shot, and the 30% speed shots are from two separate parachute upward-facing cameras.
Scott, many thanks for a super job diving into the details of Perserverance’s landing video. I’m in awe of this epic event but for me you took it to the next level.
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!
Personally, I prefer to think that DARE was a reference to the long-running British comic series, _Dan Dare,_ in which the main character visited Mars often, and saved it several times.
1:13 "they only show us one camera" ........uhhhhh, Scott those two views have the parachute and rigging in different orientations. That is two cameras.
If they lost control to point a camera, it's pretty much useless, maybe we'll get a constant stream of sky shots? Disclaimer: This is just speculation.
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...

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 came to you for Kerbal instruciton, but your real space vids are magnificent!!!!!! Don't ever stop.
Thanks for doing those unique stabilized shots too. I've been waiting for more footage and you made it even better!
Yes, that sky crane flying away also reminded of that drop ship from aliens.
10:40 Scott explains the code like it's nothing and my head explodes!
yeah, it didnt look very intuitive imo.
“The first USB 3.0 on Mars.”
Damn, I haven’t even got it on Earth.
I wonder how many times they had to flip the plug during assembly
@@fensoxx at least 3 times guaranteed
@@fensoxx More likely, they looked at the plug 3 times before trying to plug it in.
yes and whats your point? we all heard him say it.
Another amazing video, thanks Scott !!
Thanks Scott. Always the most informative videos. Really appreciate your efforts!
Your video is broken down so well and discussed about the best on the internet that's why I subscribe to your Channel
better than the NASA press conference
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.
SkyCrane flying away playing DARE . . . "Don't . . . Don't you want me"
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.
Thanks Scott for another amazing video! I love your technical analysis and summary of these important events.
"Thanks for flying us, Sky Crane! Fly... to victory!" Haha!
Should have closed with “drive safe!”

Another excellent video Scott thanks!
thanks Scott, for the very detailed explanation of all the parts and hidden stuff of the descent video!
Thx man, well done!! :3
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
Like many things, it's easy when you know how...
the footage is really breathtaking
It's pretty incredible that everything being currently sent to mars, will one day be the hosts of mars archeological dig sites in the future.
Scott your powers of observation amaze me. An astonishing video and brilliant - yet accessible - analysis.
An excellent presentation Scott.
So cool! Thank you, Scott! The two downvotes are from Martians who have to clean-up all the trash from the heat shield and drop-ship.
Tell me someone said "Detach cables" and someone else responded "Cables detached!"
You know whoever wrote the code made some form of internal joke about that.

“Dare mighty things” comes from an 1899 speech by Theodore Roosevelt.
"Far better it is to dare mighty things, to win glorious triumphs, even though checkered by failure, than to rank with those poor spirits who neither enjoy nor suffer much, because they live in the gray twilight that knows not victory nor defeat."
The speech also reflected the American spirit at the turn of the 20th century. The increasing industrialization and urbanization of America led many to become fearful of growing weak. College sports were on the rise, as were recreational athletics such as bicycling. American culture embraced masculinity, patriotism, and nationalism Issues of masculinity were especially predominant during this time, given the various women's movements of the age. Critics and scholars, including author Henry James, worried about a femininization of America. The time was ripe for Roosevelt to extol the masculine virtues of the strenuous life. Roosevelt used the speech to justify American imperialism as well.
Well fancy that...!! 🙂
Thanks! That was really interesting.
ruh roh.
One of the better videos, with explanations, thanks!
Hey great commentary on everything. I understood it better than the press conference.
Scott - the parachute video is from two different cameras. Note the orientation of the chute , cables, and shadows.
You say that there was one camera at 75 fps during the parachute sequence, but the left and right images are obviously from different points of view, hence different cameras! (Look at the orientation of the stripes in the parachute, and direction of the sun)
Yeah, but later he mentions that there's another camera connected via USB3 to the rover. So I think he meant that only _one_ of the 75fps cameras was working, and wasn't counting the 30fps camera.
@@hjalfi There were 6 EDL cameras attached over USB in total. 3 looking up at the parachute at 75fps, one down from the sky crane to the rover, one from the rover up towards the skycrane, and one looking down towards the surface from the rover. I believe the real-time speed shot, and the 30% speed shots are from two separate parachute upward-facing cameras.
They only showed one view at the news conference.
I always say out loud with you, “Fly Safe!” But, this time you fooled me! 🤣
Same
Fitting commemoration of the historic event. Thanks Scott.
Scott, many thanks for a super job diving into the details of Perserverance’s landing video. I’m in awe of this epic event but for me you took it to the next level.
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!
Personally, I prefer to think that DARE was a reference to the long-running British comic series, _Dan Dare,_ in which the main character visited Mars often, and saved it several times.
Place your comma inside the low line like this "_Dan Dare,_" and, voila! _Dan Dare,_
The first thing I thought of was "DARE to resist…" 😐
@@ominous-omnipresent-they Huh. Cheers. Of course, now the comma is italicised, which offends my pedant's soul.
@@Iam2sheds Dan Dare doesn't know it, he doesn't know it, he doesn't know it, but I liked the Mekon.
The first thing I thought of was Dare Iced Coffee.
I watched the NASA video thinking Scott Manley wil analyse the crap out off it!
With all the things that could go wrong it’s incredible they pulled it off. The image quality is fabulous. So sharp.
Rover missions have a 60% fail rate
Thanks for the tour. Was in depth and brief. Awesome channel.
1:13 "they only show us one camera" ........uhhhhh, Scott those two views have the parachute and rigging in different orientations. That is two cameras.
That's what I thought, and couldn't work out why Scott said there was only one
If they lost control to point a camera, it's pretty much useless, maybe we'll get a constant stream of sky shots?
Disclaimer: This is just speculation.
@@Kineth1 the EDL cams were all fixed cameras.
I believe there were three cameras, and one failed, hence two videos of the parachute..
There were 3 cameras. One failed. In the press conference, they only showed the view from one. The other video was made available later.
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...
I saw that pattern on the parachute I thought it looked like a bar code like on groceries.
Once again Scott a great commentary!
Thanks for decoding the parachute! Nice to see them having fun...
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".
