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.

Using its left navigation camera, the Mars Exploration Rover Opportunity sought to capture some clouds on its 153rd sol on Mars (June 28, 2004). The presence of morning clouds in the area of Endurance Crater was established by spacecraft orbiting Mars. Mars has three kinds of clouds: dust clouds low in the atmosphere; water clouds near the surface up to heights of 20 kilometers (about 12 miles); and carbon dioxide clouds at very high altitudes.

Just as on Earth, clouds, especially water clouds, are good tracers of the weather. Based on orbital data, more clouds are expected during the martian winter. As this change occurs, the rover's cameras and miniature thermal emission spectrometer will track other changes that occur as the clouds accumulate.

The rovers provide a unique opportunity to examine the lower portion of Mars' atmosphere. The lower atmosphere is difficult to characterize from orbit, but it is critical because that is where the atmosphere interacts with the surface. Since the rovers landed, the science team has been using the rover's miniature thermal emission spectrometer instrument to see the weather at this bottom layer.
