An experiment that took place on Mars has shown that it's feasible to extract breathable oxygen from the thin Martian atmosphere.
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."The MOXIE experiment, designed by MIT scientists, has been running since Perseverance landed on Mars in February 2021. Not continuously; operators here on Earth sent commands to MOXIE to see how it runsSince then, over 16 runs, MOXIE has produced a total 122 grams of oxygen.
Each run takes a few hours. Following several hours of warming up, MOXIE gathers oxygen for 1 hour per experiment followed by a period of powering down. In this hour of operation, MOXIE isThat's on paper, at least. How much it actually managed to produce varied; on its sixteenth run, on 7 August, MOXIE extracted about 9.8 grams of breathable oxygen, which was pretty close to its goal. This shows that, as thin and tenuous as the Martian atmosphere is, it can yield a supply of oxygen.
But with what they have learnt from MOXIE, researchers under physicist and MOXIE principal investigator Michael Hecht of MIT believe they can develop a full-scale system including a new-and-improved version of the oxygen-extracting device, a means to liquefy that gas, and a way to store the liquid. Future Martian explorers are going to need all the help they can get in being self-sufficient. Between the breathing requirements of a team of astronauts living on Mars for a year, and the liquid propellant needed to power a spacecraft, someIt's going to have to wait, though. There are many problems that need to be tested and solved before humans attempt a long stay on the red planet. Oxygen is just one of them..
