I'm doing it again, but I'll be brief. Fact 1: white colored tank
foam piece (recall its natural color is orange) hits Shuttle's left
wing; fact 2: foam (plus water ice--many's conjecture,including mine)
explodes into cloud of white particles (like a snowball hit); fact 3:

entire shuttle orbiter system was traveling at 3,600 miles an hour,' Mr.
O'Keefe said. 'The piece came off, dropped roughly 40 feet at a rate of

Ditto for Mars and Venus. In fact from what I've heard, the area just above the cloud-tops on Venus has an atmospheric pressure equal to that of Earth at Sea Level.

Title: Zepplin Europa?
I thought Europa didn't have enough atmosphere to support a Zepplin? Maybe a "moon hopper" would be a cheap means of locomotion that could manage jumbled terrain? Still, it seems the JIMO orbiter will sense enough of the surface. It seems a higher priority would be a
