Mars Exploration Rovers

August 2, 2019. Spirit MI calibrated products from sols 1277 through 2174 have been recalibrated. See ERRATA.TXT and the MER-A MI Calibration Revisions document for details.

March 8, 2019. The MER archives are in the process of migration to the PDS4 standard. The original PDS3 data products, labels, and documentation will remain available just as they are now; the only change is that PDS4 labels and documentation will be added to the archives. The data files themselves will not change. The MER Analyst's Notebook will also remain available. More information will be posted here as the migration is completed.

The Mars Exploration Rover Mission sent two rovers, Spirit and Opportunity, to Mars in January of 2004. Originally designed for only a 90-day mission, Spirit operated until 2010 and Opportunity until 2018, returning a wealth of science and engineering data. The PDS archives for MER reside at the Geosciences, Imaging, Atmospheres, and NAIF Nodes.

Geosciences Node Data

The Geosciences Node MER online data repository provides direct links into those MER data sets that reside at Geosciences.
MER Analyst's Notebook The MER Analyst's Notebook is for scientists familiar with MER who want details of the science observations.
