Summary
[edit]DescriptionPIA21556 - Icy Flow in a Crater.jpg |
English: The material on the floor of this crater appears to have flowed like ice, and contains pits that might result from sublimation of subsurface ice. The surface is entirely dust-covered today. There probably was ice here sometime in the past, but could it persist at some depth?
This crater is at latitude 26 degrees north, and near-surface ice at this latitude (rather than further toward one of the poles) could be a valuable resource for future human exploration. A future orbiter with a special kind of radar instrument could answer the question of whether or not there is shallow ice at low latitudes on Mars. The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. [The original image scale is 57.5 centimeters (22.6 inches) per pixel (with 2 x 2 binning); objects on the order of 172 centimeters (67.7 inches) across are resolved.] North is up. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington. |
