Mars Perseverance rover successfully inhaled carbon dioxide and exhaled oxygen | Boing Boing


The Perseverance rover has efficiently transformed carbon dioxide from the Crimson Planet’s ambiance into oxygen. Ultimately, the know-how contained in the toaster-size Mars Oxygen In-Situ Useful resource Utilization Experiment (MOXIE) unit in Perseverance’s stomach might assist human visits and even perhaps settlements on Mars. From NASA:

Whereas the know-how demonstration is simply getting began, it might pave the way in which for science fiction to grow to be science truth – isolating and storing oxygen on Mars to assist energy rockets that would raise astronauts off the planet’s floor. Such units additionally may at some point present breathable air for astronauts themselves

To burn its gas, a rocket will need to have extra oxygen by weight. To get 4 astronauts off the Martian floor on a future mission would require roughly 15,000 kilos (7 metric tons) of rocket gas and 55,000 kilos (25 metric tons) of oxygen. In distinction, astronauts residing and dealing on Mars would require far much less oxygen to breathe. “The astronauts who spend a 12 months on the floor will perhaps use one metric ton between them,” Hecht mentioned.

Hauling 25 metric tons of oxygen from Earth to Mars can be an arduous job. Transporting a one-ton oxygen converter – a bigger, extra highly effective descendant of MOXIE that would produce these 25 tons – can be way more economical and sensible.

Mars’ ambiance is 96% carbon dioxide. MOXIE works by separating oxygen atoms from carbon dioxide molecules, that are made up of 1 carbon atom and two oxygen atoms. A waste product, carbon monoxide, is emitted into the Martian ambiance.

The rover has been inverted in order that the inside is extra accessible. MOXIE will “breathe in” the CO2-rich ambiance and “breathe out” a small quantity of oxygen, to exhibit a know-how that might be vital for future human missions to Mars.”
