Iamroooared, I had the same thought, so many variables=so many ways it can go wrong. |

If all that multistage parachute/hovering rockets/lowering gantry sequence goes off without a hitch... wow |

geh. watching this makes me feel like such an alien... except not the kind of alien that comes down in cylinders and shoots lasers at the host species. |

Like the lunar landings, it's all fake.
They get ILM to do the special effects and shoot it all in the desert.
Yep. Conspiracy to hide the secret bases on Mars. |

thlonious, whatchu talkin bout?! The last one bypassed the need for a complicated system for scanning/implementing results of topographical data by simply saying "Fine, we'll crash then" and installing ridiculous airbags! Call it caveman-ish if you like; I think it's brilliant!
(See Mr Atari's lovely link for that demo, plus beer humor) |

"i never get how those jets at 0:14 to 0:24 work - what are they pushing against?"
Well... nothing.
It's that old classic, every action has an equal and opposite reaction.
Think of it as the spacecraft pushing off the exhaust of the rocket, if it helps.
When you shoot a rifle, the kickback isn't because the bullet is pushing on the air. It's because of the amount of force you just shot in the opposite direction.
The usual analogy is to imagine yourself on rollerskates, throwing something heavy away from you. It send you backwards.
The only thing that normally stops you from being propelled the other way everytime you toss, push, move anything is your friction. |

Cool. They've finally figured out that a "last mile" deployment of the craft will need some topical scan data to let it get full deployment without a crash. I think Vonnegut should get some credit for getting spacecraft out of caves. |

"I agree, very (maybe too) complex, and the higher the complexity the greater chance/odds of something going wrong. Like several other missions, will this fail and go permanently off-line 5 minutes before landing ?? I hope not...."
they haven’t had any rover fails for mars. only fail they thought they had was a rover that the solar panels got cover in sand and the battery died. and some other rover fell to hard or something and a wheel broke. |

Besides the part where there were noises in space, this is pretty awesome. I've always wanted to visit another planet, perhaps one with a little more going on then Mars; I know I never will, but it's fun to think about. |

...and how many steps/stages/operations have to go flawlessly to get this thing safely on the Martian surface, much less running around beaming photos back home? Orbital insertion, lander pod separation, atmospheric entry, parachute deployment, heat shield drop, rocket & rover package separation, retro rocket fire, winch operation, soft landing - am I leaving anything out? I wish NASA the best of luck. |

I hope in the time I'm alive they're about to fully explore Europa, Titan, and Triton. That would be amazing to see. |

Cool video, but what's with the 'dull roar of space' sound? And all the other sounds in space... I thought no sound was possible. Makes the video much better tho! |
