MOXIE
MOXIE or Mars Oxygen In-Situ Resource Utilisation Experiment is an instrument for producing oxygen. It is onboard the Perseverance rover and it makes use of atmospheric carbon dioxide as the raw material for producing 10 g of oxygen using 300 watts of power. If the MOXIE experiment proves to be successful, it could be scaled up to provide oxygen to support breathing needs of humans and also fuel the rocket’s return to earth.
