Abstract

MOXIE [Mars Oxygen In Situ Resource Utilization (ISRU) Experiment] is the first demonstration of ISRU on another planet, producing oxygen by solid oxide electrolysis of carbon dioxide in the martian atmosphere. A scaled-up MOXIE would contribute to sustainable human exploration of Mars by producing on-site the tens of tons of oxygen required for a rocket to transport astronauts off the surface of Mars, instead of having to launch hundreds of tons of material from Earth's surface to transport the required oxygen to Mars. MOXIE has produced oxygen seven times between landing in February 2021 and the end of 2021 and will continue to demonstrate oxygen production during night and day throughout all martian seasons. This paper reviews what MOXIE has accomplished and the implications for larger-scale oxygen-producing systems.

摘要

火星原位资源利用制氧实验（MOXIE）是在另一颗行星上进行的首次原位资源利用示范，通过对火星大气中的二氧化碳进行固体氧化物电解来制取氧气。一个放大版的MOXIE将通过在火星现场生产火箭将宇航员送离火星表面所需的数十吨氧气，而不是从地球表面发射数百吨物资来向火星运送所需氧气，从而为人类可持续探索火星做出贡献。MOXIE在2021年2月着陆至2021年底期间已七次制取氧气，并将在整个火星季节的白天和黑夜持续演示氧气制取过程。本文回顾了MOXIE所取得的成果以及对更大规模制氧系统的意义。
