Speaking of “Water Water everywhere”, Mars has mid-latitude glaciers

Ice on Mars: Mars has belts of glaciers consisting of frozen water. A thick layer of dust covers them, so they just look like part of the ground until recent data from the Mars Reconnaissance Orbiter.

“We have calculated that the ice in the glaciers is equivalent to over 150 billion cubic meters of ice — that much ice could cover the entire surface of Mars with 1.1 meters of ice. The ice at the mid-latitudes is therefore an important part of Mars’ water reservoir,” explains Nanna Bjørnholt Karlsson.
That the ice has not evaporated out into space could actually mean that the thick layer of dust is protecting the ice. The atmospheric pressure on Mars is so low that water ice simply evaporates and becomes water vapour. But the glaciers are well protected under the thick layer of dust.

It’s turning out that you can’t swing a dead cat without finding water in the solar system. Speaking of swinging a cat:

I’ve seen this a gazillion times, and this cat-lover still thinks it’s one of the funniest videos ever. Note that the cat runs off, so it survived impact.
