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.
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.
