W
hen the first astronauts land on Mars, they may have the
descendants of a microwave-oven-size device to thank for
the air they breathe and the rocket propellant that gets them
home. That device, called MOXIE (Mars Oxygen In-Situ Resource
Utilization Experiment), has generated oxygen for the
16th
and final time aboard NASA's Perseverance rover. After the
instrument proved far more successful than its creators at the
Massachusetts Institute of Technology (MIT) expected, its operations
are concluding.
" MOXIE's impressive performance shows that it is feasible to
extract oxygen from Mars' atmosphere - oxygen that could
help supply breathable air or rocket propellant to future astronauts, "
said NASA Deputy Administrator Pam Melroy. " Developing
technologies that let us use resources on the Moon and
Mars is critical to build a long-term lunar presence, create a
robust lunar economy, and allow us to support an initial human
exploration campaign to Mars.
Since Perseverance landed on Mars in 2021, MOXIE has generated
a total of 122 grams of oxygen - about what a small dog breathes
in 10 hours. At its most efficient, MOXIE was able to produce 12
grams of oxygen an hour - twice as much as NASA's original goals
for the instrument - at 98 percent purity or better. On its 16th
run,
on August 7, the instrument made 9.8 g of oxygen. MOXIE successfully
completed all of its technical requirements and was operated
at a variety of conditions throughout a full Mars year, allowing the
instrument's developers to learn a great deal about the technology.
MOXIE (Mars Oxygen In-situ Resource Utilization Experiment) is lowered into the chassis of NASA's Perseverance in 2019. During the mission, MOXIE
extracted oxygen from the Martian atmosphere 16 times, testing a way that future astronauts could make rocket propellant that would launch them
back to Earth. (Image: NASA/JPL-Caltech)
