To my knowledge, this is the most complex and risky autonomous space mission that has ever been attempted. I'm still flabbergasted that it actually worked to perfection.
I was referring to the descent and landing. Rendezvous in space is easy from an engineering and programming sense.We've been doing it for decades. The size of the target isn't really important as long as your math is good and your ship has thrusters precise enough to accurately produce velocity changes. Momentum does the rest. Furthermore, in deep space, commands for corrections can be sent from Earth, and don't need to be programmed. Thus, rendezvousing with an asteroid in zero gravity (a la Rosetta) really isn't any more difficult than inserting into a specific orbit around Mars. The Curiosity landing, by contrast, had to enter the atmosphere, controlling its initial descent aerodynamically by rotating the heat shield/capsule, detach the skycrane, activate the hydrazine thrusters, nullify its horizontal velocity, hover gently to a few meters above the surface, lower the rover, detach the sling, and fly the skycrane clear...All using nothing but on-board sensors and data and fully autonomous control. And it landed perfectly to within a few kilometers of its target. So, no. Rosetta is not comparable in technical, engineering, and programming difficulty to the landing of Curiosity. Not even close.
EnDSchultz1 Yeah, not convinced by your argument there. You seem to brush off the achievements of the Rosetta mission a bit quickly, while blowing out of proportion the Curiosity ones. (now don't get me wrong, Curiosity is amazing too !) You could say we've been re-entering atmospheres for decades too. Doing it on Mars is basically just giving it sensors and programming it so that it does it without direct human control. By the way, having an atmosphere is nice, it means you don't need as much fuel to decelerate. Meanwhile Rosetta had to go at just the right speed, to just the right place to orbit Churi - and they have very limited fuel to do so. And that's after a ten-year journey through space (compared to that, Mars is our neighbour). After that they had to drop Philae on a mess of a surface, again just at the right speed so that it didn't bounce off the comet - and they couldn't do it manually because it was (if I recall) 30 light-minutes away. So let's just say both feats are amazing, aye ? Because saying that Rosetta is "not even close" in terms of difficulty is kind of just insulting towards the people who put so much hard work into it :) (not that I am one of them, but let's be considerate anyway)
EnDSchultz1 as all the evaluations, they change with the purpose considered. you are considering the "flying" part of the project, but let's switch to the optimisation of the bare-metal hardware and we find that rosetta had to face serious challenges in terms of duration (hybernation in deep space) and resilience to "whatever" comes that far away; not mentioning all the previous manouvers (years-long) needed to GET to the point. earth to mars paths are pretty known. but as always, every project has different aims hence different perks and focuses, so we can even say it's pointless to compare technical difficulties. BUT, one thing that rosetta achieved like no one: it was a first attempt and a success. we already tried to send rovers all over the system so we have know-how (which is HUGELY important). rosetta had none. and that's the main achievement.
This really is a masterpiece of engineering. It sat on top of 2,000,000 pounds of thrust, traveled through the intense radiation of space for 8 months and all that to touch down in a smooth manner a human would have survived. NASA engineers truly are a race on their own.
The part where the rover detaches and starts the thrusters freaks me out. SO MUCH in my mind wants to freak out and say that the thrusters won't upright it! I know better, obvs, but all the same....a masterpiece, like you said.
Hey I got this bridge in San Francisco I want to sale you for a couple of million would you like to buy it if so just send the money pay pal to me and its yours you will make the money back on toll charges in a day or so its a real lucrative investment very fruitful and I encourage you to buy it.
This animation is a major salute to the power and imagination of science, which together with the Arts, make up the twin pillars of Western Civilisation. May that dark age pillar that is built on faith and superstition, fear and the irrationale, fall at our feet so that we may pursue the future in the way that this animation suggests is possible.
It's really interesting to see the advancement in technology between the landing tech of the old rovers vs new one. A lot of computerization in this landing, very cool.
"Now then, how are we going to get this very expensive rover to safely land on Mars" "I've got an idea boss" "Are you completely deranged? Lets go with it anyway" This has to be one of the greatest achievements in space exploration ever along with landing a probe on a comet.
Absolutely awesome. That is so cool. What a great combination of strategies and solutions. Happy trails for the whole mission. I can hardly wait to see it get there.
Whenever I see this again, I'm flabbergasted. When she landed, I stayed up into the deep night to 'whitness' it live. Absolutely awesome feat. It sadly also flabbergasts me enormously that there are actually a lot of people who don't 'believe' this has happened ! The average intelligence of mankind is indeed dropping fast...
Same here! I remember that 2012 August night so well, it was so exciting. I remember no body I knew really cared but I was extremely excited about it. It really was nerve wrecking waiting for that data to come back to earth to confirm the landing. When it arrived I shouted with joy as did the entire world. Gosh what a great time we live in
@Northstarrr Oh yes. Doubting everything scientific, only using science when it's needed to manipulate(climate change, Corona). It's far easier to controle people that are in doubt about even the most obvious things, then it is to control well educated and knowledgable people. This is also why the left has taken over the entire educational system.
@Northstarrr Ah, I see you're well indoctrinated by the left too. Shedding anything remotely critical to the leftist dogma's as 'conspiracy theories'. Easy and lazy. Means you don't have to think critically. It means you're a good drone.
Just think. You were born at the right time in history where not only was this possible, but we actually made it happen. We are living in a true golden age of human achievement. Nowhere in history except for the moon landings has humanity achieved so much in so little time. We are truly blessed to be living in this age. Just think, Curiosity is STILL OUT THERE, RIGHT NOW, roving around on Mars. Every time it turns its wheels, every valley it traverses, every cliff and hill it spots with its cameras are new frontiers that human kind has never seen before. God bless human ingenuity and our ability to make dreams come true.

The landing process looks a lot riskier than previous missions, I really hope that nothing goes wrong. Good luck to NASA and all us who love scientific exploration.
first of all lets hear 1 big awwww! for the poor sky crane. thanks for very carefully lowering our a few million dollar toy but you can go fly off and crash now. whoosh! as if it had a choice. its programed to take itself out of the game and view.lol. but for real here, in the real air drop you can't even tell when the shoot lets go and the jets engage. so smooth of a first landing. this kind of animation I love. WELL DONE NASA! And I read someone from the great land of Russia in here. Great sport you are Mak! by the way I'm hafe Ukraine. or maybe I should be saying, Cuz!
Nao sei se vc ainda vai ler minha resposta ou se já teve acesso a informacao. Mas lá vai. Ele tem um gerador nuclear que pela decadencia de radiacao, gera calor e deste calor gera eletrecidade.
Curiosity looks so sad after the rocket thingy crashes.. like it doesn't know why it's there and where all the humans went. then it drives along trying to find humans.. lasering a cat to death along the way
@@zackriggs293 we will never know because apparently they had the technology but they lost it . Therefore we will never find out how technologically advanced they were back in 1969
One of the best thing about dude is that he never takes credit for himself when he archives something He always respect us, the audience and his team and he is polite in all his videos We congratulate ourselves on this achievement
It is assumed that Mars has an atmosphere substantial enough to carry sound, I've never really gone there to check, but I think even 10 millibars is enough to allow for at least a small amount of noise.
Seventythird I meant after it left Earth's atmosphere, it was in space and when it passed the camera at about 0:34, there was sound, when there should have been none. Also, I would think that sound would travel on Mars due to its atmosphere. I've actually never checked to see how thin it's atmosphere is, but I've always thought sound would travel on Mars... Hope that clears up the confusion... if there was any...
***** How is it lame? No really? What makes it lame versus just not a good joke... It wasn't even supposed to be a joke exactly, more of laughing about something silly, on my part, and pointing it out to others, making them think about it, and maybe have a laugh too. Or are you just joking around too?
The pressure is less than one percent of earths atmosphere but there are still plenty of gases. Enough for flight by a drone (potentially. They are testing it for the next rover). I’d argue there is probably also enough to carry sound. It would be different I’m sure- but still present.
