I cured that " Lipsynch " issue #6 , I had to watch it with NO audio and this is still very impressive indeed, Just look at technology and the way it has evolved and developed over the last " 5o yrs " I want me a Hoverboard, Invent one of those next please nice Mr scientist

Oh... how far we have come from our caves, sticks and stones. It was just yesterday we where hunting wild boar with a flint hammer.
I will be watching this on the 5th, but as hopeful as i am... I have to admit, there are a lot of things that can go wrong. Can it even hover in the thin atmosphere?

wow, I can see why they call it 7 minutes of terror, its 7 min of watching billions of dollars of equipment and thousands of hours of work guide itself threw some insane maneuvers, and not being able to do anything but watch as it either lands safely.... or one little thing goes wrong and it just crash and burns.
Though what I want to know is what was wrong with the first landing design, you know, with the huge balloons and just letting the rover bounce when it hits the surface?

#16 the parachute cannot slow down the rover below 200mph (320kmh) because the atmosphere is too thin and differs in composition from ours (different gases = different density and friction). Also add the different gravity...
Additionnaly, the balloon is not a precise enough option when it comes to "where do we land". The rover must absolutely land in a valley, otherwise it would be useless. And the balloon has to fall far from the rover not to smother it !
PS : sorry for my foreign english

#5 And why do we do it? Not because it is easy, but because it is hard...
