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.

Original Caption Released with Image:

The rock abrasion tool on NASA's Mars Exploration Rover Spirit ground two holes in a relatively soft rock called "Wooly Patch" near the base of the "Columbia Hills" inside Gusev Crater on Mars. This approximately true-color image from the panoramic camera was taken on sol 200 (July 25, 2004) and generated using the camera's 600-, 530-, and 480-nanometer filters. It shows the natural red and reddish-brown color of the rock. Scientists speculate that this relatively soft rock (compared to others analyzed by Spirit) may have been modified by water. Small cracks in the surface outside the drill holes may be the result of interactions with water-rich fluids.
