re: Another source
That's pretty much the same as the original article, there isn't much new there.
The upper crust of Mars is cold and stiff. The surface of Mars is dead.
However, Mars is still a planet loaded with water (ice).
Screw Mars, Ceres is where the action is.
Next Nick will be proclaiming 'Ceres has no water'!
P.S. I've been wrong about a lot of things on Mars myself. I freely admit to being wrong about 'dry dust avalanches' but I'm pretty sure dry dust avalanches are water ice sublimation related. The big question at Ceres is : how deep is the ice, or alternatively, how deep to we have to dig to get to it. I'm hoping - not much.
Of course, hope isn't a valid scientific method but Ceres does look pretty beat up.
