How NASA’s Perseverance is making oxygen on Mars

Published

on



One of many many pesky limitations to people freely exploring and inhabiting Mars is the planet’s lack of oxygen. Fortunately, NASA’s Perseverance rover can assist.

Utilizing an instrument dubbed MOXIE (quick for Mars Oxygen In-Situ Useful resource Utilization Experiment), the rover efficiently took carbon dioxide from the Martian environment and transformed it into oxygen, NASA announced on Tuesday. NASA stated it plans to conduct extra MOXIE checks, however didn’t specify when.

MOXIE ran its first check for roughly an hour, producing just below six grams of oxygen. That’s sufficient to maintain an astronaut going for about 10 minutes, the company defined. It will not hold somebody alive for lengthy, however it’s a key step ahead in exploring Mars.

“You may think about scaling that up and having a much bigger plan for people after we lastly ship them there”

Not solely may that oxygen be used to permit individuals to breathe, however it could additionally lighten the load for return missions to Earth, or for journeys to different components of the photo voltaic system. Rockets want oxygen to burn gas throughout liftoff. Having the ability to create it on Mars would imply spacecraft can deliver much less of it from Earth, considerably reducing their weight. Much less weight means much less general gas wanted to generate elevate.

“Oxygen is the heavier a part of rocket gas,” defined Michael Meyer, Mars Exploration Program lead scientist at NASA, over the cellphone earlier this 12 months. If NASA wished to get 4 astronauts off Mars, the spacecraft would wish 27.5 tons of oxygen to do it. Retaining these 4 respiration for a 12 months would require about one ton.

On the charge MOXIE goes, producing 27.5 tons would take greater than 475 years. However future units may very well be bigger and extra environment friendly than the 38-pound MOXIE.

“You may think about scaling that up and having a much bigger plan for people after we lastly ship them there to make sufficient oxygen to get again off the floor and to have oxygen to breath,” stated Mitch Schulte, NASA’s Mars 2020 program scientist.

Making oxygen on Mars

On Mars, 0.13 p.c of the environment is oxygen. On Earth, it is 21 p.c.

“Mars’ environment is definitely fairly skinny and it is primarily composed of carbon dioxide,” he stated.  “On Mars we do not see something greater than a tiny whiff of oxygen and that is largely from water molecules breaking up within the environment.”

MOXIE takes benefit of that relative abundance of carbon dioxide, which is made up of 1 half carbon, two components oxygen. An electrolyzer operating at temperatures above 1,400 levels Fahrenheit creates an electrical present that separates oxygen from compressed carbon dioxide, leaving carbon monoxide waste.

MOXIE produced about six grams of oxygen per hour throughout its first check, with two momentary dips whereas it checked its components to ensure it was operating tremendous.

It was a bit wanting its marketed charge of 10 grams per hour, however this was simply the primary check. NASA is all the time cautious when testing the rover, so it would push MOXIE tougher subsequent time. 

One in every of Perseverance’s plans on Mars is to seize samples of the Martian floor in tubes, which can be picked up by a future spacecraft and delivered to Earth for examine. It will need oxygen for its takeoff from Mars. Moxie may assist create that oxygen. 

It may be helpful for NASA’s Artemis program, at the moment in its early levels. The plan is to ship individuals to the moon, after which arrange a moon-to-Mars launch system. 

It isn’t clear when NASA will launch its first manned mission to Mars. However there is a good probability MOXIE’s successor can be part of it.
