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.

PIA21605: Colorful Equatorial Gullies in Krupac Crater

Krupac is a relatively young impact crater, but exposes ancient bedrock; it also hosts some of the most impressive recurring slope lineae (RSL) on equatorial Mars outside of Valles Marineris, as seen by NASA's Mars Reconnaissance Orbiter.

Although large gullies (ravines) are concentrated at higher latitudes, there are gullies on steep slopes in equatorial regions, as seen in this image captured by NASA's Mars Reconnaissance Orbiter (MRO). An enhanced-color closeup shows part of the rim and inner slope of Krupac Crater located just 7.8 degrees south of the equator.

The colors of the gully deposits match the colors of the eroded source materials. Krupac is a relatively young impact crater, but exposes ancient bedrock. Krupac Crater also hosts some of the most impressive recurring slope lineae (RSL) on equatorial Mars outside of Valles Marineris.

Another close look shows some of RSL, flowing downhill (to the left). The RSL leave bright deposits when inactive from previous years; this year's active RSL are the thin dark lines.

The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 26.3 centimeters (10.4 inches) per pixel (with 1 x 1 binning); objects on the order of 79 centimeters (31.1 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.
