The Curiosity Mars Rover is set to land Sunday, and the way they are deploying the rover is a new technique.
The process involves a "sky crane" which (while firing it's retro rockets) lowers the rover to the martian surface, releasing the rover, and then flying away, This has never been tested on a real mars mission so this 'hit or miss" situation is either one for the record books, or a billion dollar write off.
