A single liter costs a few thousand dollars. Because there is no magnetosphere around the #Moon ๐ŸŒ™, it's believed there are large quantities of #helium3 gas trapped in pockets of the #lunar regolith. #Interlune is working toward the launch of a demonstrator mission in ๐Ÿ“† 2026 that will sample the lunar regolith, measure the helium-3 quantity, and then attempt to extract some of it. https://arstechnica.com/space/2024/03/mining-helium-3-on-the-moon-has-been-talked-about-forever-now-a-company-will-try/

Act now to prevent a โ€˜gold rushโ€™ in outer space

As private firms aim for the Moon and beyond, a book calls for an urgent relook at the legal compact that governs space exploration.

"As a rule of thumb, rockets launched from Earth must burn ~25 kg of propellant to transport one kg of payload, whereas rockets launched from the Moon would burn only ~4 kg of propellant to transport one kg of payload." https://arstechnica.com/science/2025/02/turning-the-moon-into-a-fuel-depot-will-take-a-lot-of-power

Turning the Moon into a fuel depot will take a lot of power

Getting oxygen from regolith takes 24 kWh per kilogram, and weโ€™d need tonnes.

Well, unless you can generate fuel locally cheaply and with light equipment, that propellant for lunar launches will be sent from Earth, for a total of 29 kg.
