Thanks, Emily.
Well, here's my (probably wrong) WAG. Assuming that the crater's only 5m deep & an average soil density of 3.5 g/cc, I get something like 2300 m^3 of material excavated for 8050 tonnes of mass. They're inferring 100 kg of water from that, but of course that can't be interpreted as a full scan of all exhumed material. All this says to me is that there's some water there. The means employed for detection really can't determine fine percentages of composition, IMO. EDIT: Forgot to mention that I assumed crater diameter as 30m. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
