## Summary

The 2022 peer-reviewed paper describing MOXIE's in-flight performance on Mars, coauthored by OxEon Energy engineers Joseph Hartvigsen and Singaravelu Elangovan, presented as the first demonstration of in-situ resource utilization on another planet.

## Useful Claims

- Peer-reviewed confirmation that MOXIE's Solid OXide Electrolyzer (SOXE) stack — built by OxEon Energy in North Salt Lake, Utah — split compressed Martian CO₂ into oxygen ions and carbon monoxide at high temperature, then recombined the oxygen ions into molecular O₂.
- The paper documents MOXIE as the first demonstration of in-situ resource utilization (manufacturing a usable resource from local materials) on another planet.
- OxEon engineers are named coauthors, corroborating OxEon's role as the designer/manufacturer of the electrochemical core, not merely a component supplier.

## Reliability Notes

Peer-reviewed primary literature — the highest-reliability source on this page for the technical claims about MOXIE's operation and the SOXE stack's role. Not a source for OxEon's broader business/commercialization activity; see [OxEon Energy: MOXIE Program](oxeon-moxie-program.md) for that.
