## Summary

NASA's own account of MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment) wrapping up its technology-demonstration mission aboard the Perseverance rover, after exceeding its original performance targets across repeated Mars surface runs.

## Useful Claims

- MOXIE first produced oxygen on Mars on April 20, 2021, and continued operating through August 2023 across 16 total runs.
- Over its mission, MOXIE generated 122 grams of oxygen total, reaching a peak rate of about 12 grams per hour at 98% purity or better — exceeding NASA's original technology-demonstration goals.
- NASA frames MOXIE as proof that in-situ resource utilization — manufacturing consumables like oxygen on Mars rather than launching them from Earth — is viable for future human missions.

## Reliability Notes

Primary-source NASA mission reporting; high reliability for mission facts and dates. Does not itself detail the Utah/OxEon Energy hardware provenance — see the [MOXIE Solid Oxide Electrolysis Stack](moxie-solid-oxide-electrolysis-stack.md) page and the OxEon and Science Advances source records for that.
