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.

PIA02809: MOLA Global Map of Surface Gradients on Mars
A global surface map from NASA's Mars Global Surveyor shows Mars' northern hemisphere is flatter than the douth, and shows some linear slope breaks, for example north of Alba Patera and the Tharsis province.

Absolute slopes on 30-km baselines indicate the magnitude of typical regional tilts of that scale. The Northern hemisphere is flatter than the South, and shows some linear slope breaks, for example north of Alba Patera (40N, 250E) and the Tharsis province. The major volcanos display flanks slopes of 2.5-5 degrees, comparable to Hawaiian shields. The southwest rim of the Hellas impact basin appears relatively eroded, with shallower typical slopes. A shaded relief map of the topography is overlaid is monochrome.
