Space.com reports that the Spirit rover caught these photos of Mars' moon Deimos crossing the solar disk: in other words, a Martian solar eclipse. Very cool. You can get a version of the loop here as an mpeg or here as an animated gif. Compare these to my crude transit of Mercury that I recorded back in 1999.
RoboGames (formerly ROBOlympics) is going to be held this weekend in San Francisco! How did I let this sneak up on me? II'll have to shell out my $20 and go at least one of the days. Stay tuned for a report!
