Regarding the olivine suggestion, I am not convinced at all.
I really don't see how a soil layer a few cm thick, which neighbours with water ice below, and spends six months per year covered with water ice, could contain olivine. Since it reacts so easily with water, only olivine hydrolysis products should be there. Olivine may point to dryness, but this cannot be logically reversed (and olivine was not detected) All other instruments show that the Phoenix site is not dry. The puzzle is how can the soil be consistently dry with so much water around ? How can the soil be dry when we see water condense on the legs of Phoenix ? I really enjoy the Scherlock Holmes elements this place offers us MECA sees perchlorates, but TEGA does not (so far). The TC probe points that the soil is dry, while we see the ice even with our own eyes ! I just love a good old mystery |
