Oxygen production was achieved 20 April 2021, or early morning on Sol 60 in Jezero Crater, producing 5.37 grams of oxygen in an hour, which equivalent to what an astronaut at Mars would need to breathe for roughly 10 minutes. MOXIE is designed to safely generate up to 10 grams of oxygen per hour,[16][2] with theoretical production limited to 12 grams of oxygen per hour due to the limited capacity of the 4 ampere flight power supply.[3]
