This is a really cool animation of the Mars Rover from launch on earth to its mission on Mars. The level of technical detail appears to be high to me: they studied old Mars sunset images to get the correct blue cast, and you see a lot of the rover elements in high detail. I didn't realize how many rocket stages there were to launch the thing, and it's really cool to see the rocket get smaller, and smaller, and smaller.

One other note: the "American Beauty" music coupled with the camera on the rover make it seemly oddly anthropomorphic, and there are also the Johnny 5 resemblences.
