Spirit has been capturing some amazing photographs of dust devils blowing across the Gusev plain. Visit the MER Press Release Images page to see some photos and animations created from photos. I'm fascinated by seeing weather, up close and personal, on another terrestrial planet.
We've known for quite a while that these dust devils existed on Mars, and there have been some great photos from orbit showing the devils (lower third of this MGS MOC image) and their trails (the lighter colored dust is carved away revealing the darker rock and soil below) marking up the landscape.
These Spirit images have given us a whole new vantage point and surely the science team's Martian weather folks are thrilled at the new data.
