Oxygen Made From Moon Dust For First Time

11 avril 2026 à 22:52
"Breathable oxygen has been created from Moon dust," reports the Telegraph, "in a world first that paves the way for a lunar base." Jeff Bezos's Blue Origin ""announced this week that it had developed a reactor that could successfully release oxygen from lunar soil by using an electric current." Almost half of Moon dust — the thin layer of rock that blankets the lunar surface — is oxygen, but it is bound to metals such as iron and titanium... Previous work to isolate oxygen has been lab-based, and the unwieldy equipment needed has been too difficult to send to the Moon. In contrast, Blue Origin said its small-scale reactor, named Air Pioneer, could be made flight-ready to "provide the first breath of life for a sustainable Moon base"... As well as breathable air, Blue Origin said the reactor produces other critical elements for planetary infrastructure, such as iron, aluminium and silicon for construction and electronics, as well as glass for windows and solar panel covers. The company has previously said it wants to turn the Moon, and eventually Mars, into "self-sustaining worlds where robots and humans can go beyond visiting and truly explore, grow, live, and thrive".... Blue Origin said it would need to generate around one megawatt of power to drive the reactors — about the energy it would require to power around 400 to 1,000 homes simultaneously. It envisages that each lunar settlement would have an array of nearby solar panels, generating the power needed for one reactor. Besides breathable air for astronauts, the oxygen could also be used in propellant for refuelling landers and fuel cells, Blue Origin points out — and "produced right where they're needed, and at much lower cost than being brought from Earth."
