Mars Exploration Rovers: MER Data Sets Online at Geosciences

Maintenance of MER archives is divided among the Geosciences, Imaging, Atmospheres, and NAIF Discipline Nodes of the PDS.  The list below shows only those MER data sets that reside at Geosciences. For MER data sets that do not reside at Geosciences, use the tools on the previous page or visit the other Discipline Node web sites via links in the orange bar at the bottom of the page.

Operations data are generated by MER Mission Operations. Science data are generated by the individual MER Payload Element Teams.

EDR means Experiment Data Record, or raw data. RDR means Reduced Data Record, or derived data.

Spirit is the first rover to arrive at Mars, also known as MER-A or MER-2.  Opportunity is the second rover, also known as MER-B or MER-1. A and B represent the rover missions in order of flight. 1 and 2 are the rover serial numbers.
