I was browsing around and found some intresting articles about there is some debate whether or not a metal cover for a underground nuke test a few months before Sputnik made it to space or not. Pictures from the test (launch??) give a lower bound of its velocity at 56km/s. the main argument agianst is that it would have blead off the speed in the atmosphere. anyways, kinda cool

"how do rocks from meteor impacts make it into a stable orbit?"
They don't. They either escape (like a 'Mars meteorite') or fall back down to make a secondary crater, where that elliptical orbit intersects the surface again. Phil -------------------- ... because the Solar System ain't gonna map itself.
