The Mars Space Flight Facility has developed a version of JMARS specifically for use by students and space enthusiasts. The Public Version contains all of the standard JMARS layers (e.g., Map Layer, Stamp Layer, etc.) and pulls data from the same servers at Arizona State University that supply data to the THEMIS, MRO, and LROC versions of JMARS. Users must register for a (free) JMARS account since the program requires access to the ASU servers.

The JMARS team has also released public versions of the JMoon and JEarth versions of JMARS. These let users access remote-sensing data for the Moon and Earth using a JMARS interface. For information on how to access JMoon or JEarth, please see the instructions at the bottom of this page.


What can JMARS do for me?

Students

  • K-12 students: Target a THEMIS image as part of the Mars Student Imaging Project.
  • Undergraduate students: Target and analyze THEMIS observations as part of your School of Earth and Space Exploration coursework.
  • Graduate students: Target, locate, and analyze observations made by THEMIS and other Mars-orbiting instruments as part of your individual research projects.

Space enthusiasts

  • Navigate across the Martian surface and view data collected by every NASA Mars orbiter since Viking (1976), as well as the European Space Agency's Mars Express orbiter.
  • Locate specific observations for viewing and/or analysis outside of JMARS.
  • View the past, present, or future location of the Mars Odyssey spacecraft.
  • View data for the Moon and Earth using the JMoon and JEarth versions of JMARS.
