Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

Lobate debris aprons (LDA) are commonly found surrounding dissected plateaus in the Deuteronilus Mensae region of Mars. They have been interpreted as debris-covered glaciers and radar data have shown their interiors to be composed of pure ice.

The mound in this image is slightly removed from most of the other plateaus, and the LDA surrounding it is highly degraded. The sharp scarps on the western and eastern sides of the mound indicate that a great deal of the ice once found in these landforms has since sublimated away, leaving behind these collapsed debris cliffs.

The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. (The original image scale is 30.1 centimeters [11.9 inches] per pixel [with 1 x 1 binning]; objects on the order of 90 centimeters [35.4 inches] across are resolved.) North is up.

The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. 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.
