Martian clouds drifting across the horizon

The Surface Stereo Imager onboard NASA's Phoenix Mars Lander observed clouds drifting across the horizon in the early morning on the 119th sol, or Martian day, since landing (September 25, 2008). Clouds were observed each night after Sol 80 (August 15, 2008) as the atmospheric temperature decreased.
