Dust devils

With all the excitement over Cassini and Deep Impact, I was in danger of forgetting some of our other solar system explorers. On Spirit's 501st Martian day (31st May), its navigation camera took some home movies of Martian dust devils. Rather cleverly, the folks at JPL and Texas A&M have enhanced the contrast of just the bits of the image that vary between frames. That way, the little whirlwinds appear much more obvious than they would have done otherwise. Clicking on the animation takes you to NASA's full sized version (6 MB).
