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 JEarth and JVesta. The JMARS version contains all of these bodies, including Earth. JEarth and JVesta are the same as JMARS except that they open on that particular body while JMARS opens on Mars. For information on how to access JEarth please see the instructions at the bottom of this page.
