Well, I am curious about that also. Can't the ice particles stick to
the dust in the area, causing a snow of sorts - even if it is rather
sparse - to fall on the ground?

I have seen pictures of rime, but wasn't that from another mission?

Doesn't the CO2 regularly sink down at night, seeing as how the
temperature tends to drop? Every night, there ought to be *some*
kind of condensation of H20, CO2, and dust particles, what there
are of them.

I don't know weather the condensation of CO2 occur outside of the poles, but
the low night-temperature could still make a journal shift of pressure and
windpattern.
