Maybe you did or maybe you didn't kow, Nasa tried to bring back the Genesis space capsule yesterday. And the results where ground breaking http://www.space.com/news/genesis_opened_040909.html The long and the short of it. A space capsule that had been in space for 3 years capturing ions from the Sun and space. They where going to bring it back to earth where a Helicopter was going to catch it mid-flight. Well, the chutes didn't open and it hit the ground at about 193 miles per hour.
They have now started to comb the desert.
