Testing and Modeling of the Mars Atmospheric Processing Module

Here we report further progress in the development of the MARCO POLO/Mars ISRU Pathfinder Atmospheric Processing Module (APM). The APM is designed to demonstrate in situ resource utilization (ISRU) of the Martian atmosphere, which primarily consists of carbon dioxide (CO2). The APM is part of a larger project with the overall goal of collecting and utilizing CO2 found in the atmosphere and water in the regolith of Mars to produce methane and oxygen to be used as rocket propellant, eliminating the need to import those to Mars for human missions, thus significantly reducing costs. The initial focus of NASA’s new ISRU Project is modeling of key ISRU components, such as the CO2 Freezers and the Sabatier reactor of the APM. We have designed models of those components and verified the models with the APM by gathering additional data for the CO2 Freezer and the Sabatier reactor. Future efforts will be focused on simultaneous operations of the APM and other MARCO POLO/Mars ISRU Pathfinder modules.
