That would be nice had they understood the nature of the environment,
but the soil is a big unknown, where the much more studied atmosphere
is capable of the more than a few surprises.

Unless you have an explanation of how there can be so much detected
water in the few meters of top soil, despite the low pressure problem,
then there is more than one possible explanation.


They detected *ice* in the top few meters of soil. Not liquid water.
Water cannot exist there because the pressure is too low (over almost
all the Martian surface). The low pressure does not preclude the
existence of ice, as I have already explained.

Now, are we going to iterate this several dozen more times, or are
you going to try to think about what I said? I'll give you one
more chance before I right you off as a hopeless moron.
