Bad Astronomy Blog is reporting on a nifty image fromHiRISE: An action shot from Mars, showing an avalanche in progress. I concur with BAB that this is, indeed, very cool. Our fellow dumb planets aren't just inert lumps of rock -- they have their own sounds, smells, accelerations due to gravities, good days, and bad days. It's just strange to think that no one is experiencing these things in person on a day to day basis.
