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

I can only find ISS data from Cassini for the earth flyby - nothing from any other instrument (using http://starbrite.jpl.nasa.gov/ ) so working on the assumption that this is VIMS or CIRS data -then yup - it's not been in the PDS.
I'm finding it hard to get excited about this. We're talking about something two to three times, possibly 30 times drier, than dry concrete - and even then - if I'm not misreading stuff, just in the top few mm of the regolith is this 'damp' (BBC's choice of word there) So you might get a few tens of tons of water out of ploughing through an entire square km of surface. I'm struggling to imagine that as being useful for, err, anything. It may well be that this surface smattering of H+O is all there is to the water on the moon story (given the none too positive results from radar mapping of the moons poles) - so I'm going to stick my neck out and predict a very dry LCROSS event. |
