![]() ![]() A waste product, carbon monoxide, is emitted into the Martian atmosphere. MOXIE works by separating oxygen atoms from carbon dioxide molecules, which are made up of one carbon atom and two oxygen atoms. Transporting a one-ton oxygen converter – a larger, more powerful descendant of MOXIE that could produce those 25 tons – would be far more economical and practical. ![]() Hauling 25 metric tons of oxygen from Earth to Mars would be an arduous task. “The astronauts who spend a year on the surface will maybe use one metric ton between them,” Hecht said. In contrast, astronauts living and working on Mars would require far less oxygen to breathe. Getting four astronauts off the Martian surface on a future mission would require approximately 15,000 pounds (7 metric tons) of rocket fuel and 55,000 pounds (25 metric tons) of oxygen. To burn its fuel, a rocket must have more oxygen by weight. ![]() MOXIE is an exploration technology investigation – as is the Mars Environmental Dynamics Analyzer (MEDA) weather station – and is sponsored by NASA’s Space Technology Mission Directorate (STMD) and Human Exploration and Operations Mission Directorate. Such devices also might one day provide breathable air for astronauts themselves. While the technology demonstration is just getting started, it could pave the way for science fiction to become science fact – isolating and storing oxygen on Mars to help power rockets that could lift astronauts off the planet’s surface. The test took place April 20, the 60th Martian day, or sol, since the mission landed Feb. A toaster-size, experimental instrument aboard Perseverance called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) accomplished the task. A group of four astronauts on the red planet would require an estimated 1 metric ton of oxygen between them to last an entire year, MOXIE principal investigator Michael Hecht of the Massachusetts Institute of Technology said in a NASA news release.The growing list of “firsts” for Perseverance, NASA’s newest six-wheeled robot on the Martian surface, includes converting some of the Red Planet’s thin, carbon dioxide-rich atmosphere into oxygen. "This is a critical first step at converting carbon dioxide to oxygen on Mars," said Jim Reuter, associate administrator for the Space Technology Mission Directorate.Įngineers hope that MOXIE can be scaled up to produce enough oxygen for future human flights to Mars. The Perseverance rover used an instrument known as MOXIE, or Mars Oxygen In-Situ Resource Utilization Experiment, which superheated the carbon dioxide to cleave it chemically, producing about 5 grams of pure oxygen – about enough for an astronaut to breathe for 10 minutes, according to NASA. She called it the first technology of its kind to help future missions "live off the land" of another planet. "MOXIE isn't just the first instrument to produce oxygen on another world," Trudy Kortes, director of technology demonstrations with NASA's Space Technology Mission Directorate, said in a statement. It also reached new milestones of a higher altitude, a longer hover and lateral flying. Go big or go home! The #MarsHelicopter successfully completed its 2nd flight, capturing this image with its black-and-white navigation camera. The second flight "reached new milestones of higher altitude, a longer hover and lateral flying," NASA's Jet Propulsion Laboratory said in a tweet. It came ahead of a second successful test of NASA's Ingenuity helicopter after its historic maiden flight on Monday. The feat, announced Wednesday, is considered vital to any long-term stay for humans on Mars, as bringing an ample supply of oxygen from Earth would likely prove impractical. The remainder is mostly nitrogen and argon. The Martian atmosphere is about 95% carbon dioxide. NASA announced that an instrument aboard the rover had successfully extracted carbon dioxide from the atmosphere on Mars and then electrochemically split oxygen atoms from carbon dioxide molecules. NASA announced the instrument had produced oxygen from the Martian atmosphere.Īfter making the first powered flight on another world, NASA's Mars 2020 mission has managed another key first that could pave the way for future astronauts by making breathable oxygen out of the wispy Martian air. Technicians at NASA's Jet Propulsion Laboratory lower an instrument known as MOXIE, or the Mars Oxygen In-Situ Resource Utilization Experiment, into the belly of the Perseverance rover. ![]()
