MOXIE: Mars Oxygen ISRU Experiment


Media requests: please email nwk@mit.edu.


MOXIE, the Mars Oxygen ISRU (In-situ Resource Utilization) Experiment, has been in development since the summer of 2014 and was launched with the Mars 2020 mission in July 2020. MOXIE will demonstrate a technique that may allow future explorers to produce oxygen from the Martian atmosphere for fuel and breathing.

Led by Haystack’s Associate Director Michael Hecht, MOXIE will demonstrate conversion of atmospheric CO2 to oxygen on the Martian surface, a key capability of any future human Mars mission.

MOXIE (aka “The Oxygenator”) is a 1:200 scale model of an ISRU plant for a human mission. It ingests atmospheric CO2 and produces propellant-grade O2, intended primarily for Mars Ascent Vehicle (MAV) propellant — but also as a way to supplement fuel and habitat oxygen.

MIT, including Haystack and MIT AeroAstro teams, is responsible for overall project leadership, scientific definition, laboratory characterization activities, and, eventually, interpretation and publication of results. Technical development of MOXIE hardware at JPL is complete, the instrument has been integrated into the rover, and engineering models are at Haystack for characterization in preparation for surface operations in 2021.

Countdown to Mars:

Mars Perseverance launch window opens Thursday, July 30, 2020

The launch window opens at 7:50 ET. Live coverage and countdown commentary will begin at 7 a.m. on Thursday on NASA Live, as well as YouTube, Twitter, Facebook, LinkedIn, and more.

MOXIE is the equivalent of a small tree: it will make about 6–10g of oxygen per hour. Michael Hecht, MOXIE PI
