This probably deserves it's own thread. Seems the evidence is not specific to only one mission...

Are you sure the water is limited to the top 2 mm or simply that the measurements from space are unable to see below that? I still can't find the original three papers on the AAAS website (even though I'm a member). Perhaps they'll appear tomorrow.

QUOTE (Greg Hullender @ Sep 25 2009, 02:45 AM)  Are you sure the water is limited to the top 2 mm They did explicitly mention figures like that, several times. If it is basically solar 'rain' so to speak, then I can well imagine it being little more than atomic icing. There, clearly, lots more study to be done. |

The universe today article mentions that ejecta from young craters were 'rich' in water and hydroxyl, which might mean that some of it migrates to the subsurface and sticks around. Plus it seems hard to have ultra cold traps at the poles, a continuos (but yes very tenuos) supply of water and hydroxyl, and not have significant amounts of ice to accumulate in the subsurface of said cold traps over geological time (micrometeorite impacts might drive off surface ice faster than it can accumulate). It seems logical that there will be areas with only an atomic icing and areas with relatively large amounts at a certain depth. The moon does not seem as dead as once thought today, and coupled with the news of very pure ice on mars it's been a good week for finding ice in the inner solar system. -------------------- |
