PDS Information
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.

PIA23854: Keeping a Watchful Eye
This image acquired on March 27, 2020 by NASA's Mars Reconnaissance Orbiter, shows a couple of dark lineations on the equator-facing wall of this impact crater that resemble small recurring slope lineae (RSL).

Existing images of this impact crater show a couple of dark lineations on the equator-facing wall that resemble small recurring slope lineae (RSL). However, unlike typical RSL, these lines persist for several Mars years with only minor changes.

We are continuing to monitor this site to understand how they differ from "standard" recurring slope lineae.

The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. (The original image scale is 28.8 centimeters [11.3 inches] per pixel [with 1 x 1 binning]; objects on the order of 86 centimeters [33.9 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.
