Curiosity Rover, August 5

Footage from Mission Control at the Jet Propulsion Laboratory on the night of August 5 as the Mars Rover, Curiosity, successfully landed on Mars; interspersed with the animation that JPL had done of all the steps in the process, from hitting the atmosphere to landing on the surface of the planet, that made it work: http://www.ustream.tv/recorded/24590920

And Jon Stewart does a lovely job on the landing with his spot, "Live at Red Rocks":
