This sequence combines 32 images of clouds moving eastward across a
Martian horizon. The Surface Stereo Imager on NASA's Phoenix Mars Lander
took this set of images on Sept. 18, 2008, during early afternoon hours of
the 113th Martian day of the mission.
The view is toward the north. The actual elapsed time between the first
image and the last image is nearly half an hour. The numbers inset at
lower left are the elapsed time, in seconds, after the first image of the
sequence. The particles in the clouds are water-ice, as in cirrus clouds
on Earth.
Phoenix landed in the northern region of Mars on May 25, 2008. The mission is
led by the University of Arizona, Tucson, on behalf of NASA. Project
management of the mission is led by NASA's Jet Propulsion Laboratory,
Pasadena, Calif. Spacecraft development was by Lockheed Martin Space
Systems, Denver.
