JMARS

JMARS is an acronym that stands for Java Mission-planning and Analysis for Remote Sensing. It is a geospatial information system (GIS) developed by ASU’s Mars Space Flight Facility to provide mission planning and data-analysis tools to NASA scientists, instrument team members, students of all ages and the general public. JMARS has been available to the public since 2003. It is used in over 65 countries and has over 6,000 active users.

JMARS provides free and efficient access to more than a terabyte of NASA orbiter data, and has basic image and vector-processing features to conveniently compare, plot, and blend data.

While JMARS began with a focus on Mars, it now includes data for Earth, Earth’s Moon, Venus, Jupiter’s moons, Mercury, asteroids Ceres and Vesta, and more. In all its variants, it’s free to use and open-sourced, and is actively supported on Mac, Windows, Linux, and Solaris.

JMARS can simultaneously display multiple datasets (such as maps, image footprints, numerical data products, etc.) collected by instruments on several past and current NASA missions.

New datasets are constantly being added to JMARS from all missions and instruments as new data are collected and existing data undergoes further processing and analysis.
