RE: [meteorite-list] Mystery Spheres on Mars Finally Identified

at low temperture and pressure water tends to sublime, ie change directly to 
the gas phase from a solid, as opposed to melt, then boil away, so unless 
the water was liquified by impact, a comet wouldnt be a good source of free 
liquid water on mars..

Just a thought, but couldn't the spherules have been formed by slow
boiling water from a cometry impact containing water & iron/minerals? -
Since the atmospheric pressure is very low (and likely has been pretty
thin through most of mars history) any standing water from say a big
comet impact would have begun to boil would it not? - thereby forming
iron rich spherical minerals...
Anyone fancy boiling a large chunk of tagish lake in water to test the
theory?  :)
Best,
