MARS is the Java Mission-planning and Analysis for Remote Sensing. It is a geospatial information system (GIS) developed by the Arizona State University’s Mars Space Flight Facility to provide mission planning and data-analysis tools to NASA’s orbiters, instrument team members, students of all ages, and the general public.

A new and improved version, JMARS 3.0, is now available. This version has quite a few new features.
