Re: Ice on the Moon... or?
Raoul — (archived)

Jack Schmitt isn't convinced the H2 found on the Moon's poles are from ice.
His argument goes as follows:
Comets impact the Moon everywhere and also the Moon's poles.
There might very well be ice deposits there as those places are in permanent darkness thus very cold.
However, meteorites, even small ones keep hitting the Moon all the time (he even saw such an impact from moon orbit (a flash)). Meaning, those meteorites also continuously hit the ice. Such an event vaporizes the ice and it can't stay in the icy form for a long time.
But Hydrogen coming from the Sun keeps pouring on the Moon! (just like Helium 3 but in much larger quantities) . The cold will keep the hydrogen on the surface until it gets hit by a meteorite but as hydrogen keeps coming anyway....
