MIP: the First ISRU Flight Experiment
In 2020, the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) will fly to Mars as part of the Mars-2020 “Perseverance” rover’s experiment package, and for the first time will demonstrate the use of in-situ resources of another planet, by using the carbon dioxide atmosphere of Mars as a feedstock to produce oxygen. MOXIE, however, was not the first flight experiment proposed to test in-situ resource utilization (ISRU). The Mars ISPP Precursor, “MIP”, was a flight experiment on the 2001 Mars Surveyor Lander that was designed to demonstrate In-situ Propellant Production--ISPP--for the first time on Mars. The experiment was designed to show that it was possible to produce oxygen from the carbon dioxide atmosphere, and to demonstrate the individual technology components that would go into a full-scale production plant. The aim point of the oxygen production was to showcase the possibility of producing oxygen for use as rocket fuel, ultimately as an enabling technology for a future human expedition to Mars.

The aimpoint of the oxygen production was to showcase the possibility of producing oxygen for use as rocket fuel, ultimately as an enabling technology for a future human expedition to Mars. The MIP team built and qualified flight hardware for the experiment to fly on the Surveyor-2001 lander, but following the failure of the 1999 Mars Polar Lander spacecraft, the Surveyor-2001 lander mission was cancelled, and the MIP experiment was never flown. The experience in building and testing the hardware did show that the carbon dioxide electrolysis process was feasible, and led to incorporation of in-situ propellant production into the NASA reference plans for human Mars missions. Twenty years later, the technology is flying to Mars in the form of the MOXIE experiment on the Perseverance rover.
