But I think it's still good to continue looking at the moon. In particular, I hope China studies the North and South Poles of the moon. I think I read that there is speculation about the existance of ice there? I know water cannot exist on the moon because there is a total vacuum there (unlike Mars which has a CO2 atmosphere...)
I would have thought that the ice would also sublime but perhaps the cold keeps it from subliming...
I would have to agree with you, that Mars is much more interesting. The moon is still fascinating, and I'm sure there is much more to explore, but I'm enthralled with the pictures the rovers are sending back from Mars. I check the web site every day for new pictures: http://marsrovers.jpl.nasa.gov/home/index.html
Regarding ice on the moon, I have read that ice would not sublimate, even in a vaccum, if it was below -270F. (such as the dark side of a crater)
It will be interesting to see what proofs scientists come up with for the presence of water on Mars.
