Meteorite shockwaves trigger dust avalanches on Mars

(PhysOrg.com) -- Dust avalanches around impact craters on Mars appear to be the result of the shock wave preceding the actual impact, according to a study led by an undergraduate student at the UA.

Winds of change strike Mars, too

Mysterious dark sand dunes around Mars' northern polar cap are shifting with the seasons, as carbon dioxide gas changes form and sparks landscape-altering avalanches, said a study published Thursday.
