The skycrane system is just SO COOL. It's also one of those things that is super easy to explain but incredibly difficult to actually construct, let alone have it work well after flying all the way to Mars.
i can't believe it works. Those thrusters making all that turbulence and racket. Then the cables have to unwind without getting tangled and at the same rate. Then, finally, at the end, they have to detach the cables and fly away. It's pretty nuts.
