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.

Rates of change in surface temperatures during a martian day indicate differences in particle size in and near "Bonneville Crater." Temperature information from the miniature thermal emission spectrometer on NASA's Mars Exploration Rover Spirit is overlaid onto a view of the site from Spirit's panoramic camera. This sequence of five frames begins at the top with data from 10:15 a.m. (PIA05928) local solar time at Spirit's location inside Mars' Gusev Crater. The times of the subsequent frames are 11:49 a.m. (PIA05929), 1:35 p.m. (PIA05930), 2:35 p.m. (PIA05931), and 4:39 p.m.(PIA05932).

In this color-coded map, quicker reddening during the day suggests sand or dust. (Red is about 270 Kelvin or 27 degrees Fahrenheit.) An example of this is in the shallow depression in the right foreground. Areas that stay blue longer into the day have larger rocks. (Blue indicates about 230 Kelvin or minus 45 Degrees F.) An example is the rock in the left foreground.
