PDS Information
Find a Node - Use these links to navigate to any of the 8 publicly accessible PDS Nodes.

This bar indicates that you are within the PDS enterprise which includes 6 science discipline nodes and 2 support nodes which are overseen by the Project Management Office at NASA's Goddard Space Flight Center (GSFC). Each node is led by an expert in the subject discipline, supported by an advisory group of other practitioners of that discipline, and subject to selection and approval under a regular NASA Research Announcement.

The engineering model (EM), an almost identical twin of MOXIE, is used for testing in the lab at NASA's Jet Propulsion Laboratory in Pasadena, California. Inside this gold-plated aluminum box is the Solid Oxide Electrolysis unit, or SOXE, the heart of MOXIE. Using an electrochemical process called electrolysis, SOXE takes in the carbon dioxide gas and splits it into carbon monoxide and oxygen, which is measured for purity, filtered, and then released back into the Mars atmosphere. Tubes to take in the Mars atmosphere and vent oxygen and carbon monoxide produced by the EM are connected at the top of the EM. The electronics needed to run this complex machine are housed inside the larger sidewall seen on the right.

NASA's Jet Propulsion Laboratory in Southern California built and will manage operations of the Mars 2020 Perseverance rover for NASA.
