There's ice in craters at the poles in huge quantities, this is just a scientific curiosity. Lunar soil is "moist," who would have guessed? One of the wonderful things about space exploration, they almost never find what they were expecting to find.

Ah! But imagine the fantastic spectacle if the earth and moon could collide! Women's bodies would go truly awry and the news would be full of Tsunami stories!

@Petter Don't use a natural satellite, make one. A death star crashing into Earth would be much more fun. Plus, imagine the havoc an extra massive satellite up there could have on tides and...........................other bits.

@puff How about all non-fanatical, intelligent people move to Mars, then persuade Venus to change orbit and bounce around on earth.
