As that suggests, this process could have an upshot for Moon explorers by producing useful alloys to construct habitats or repair vehicles.

There's a lot of work needed before plants like this can go to the Moon. It needs to store oxygen instead of simply venting the gas. Likewise, scientists would need to determine what alloys would be the most useful byproducts. A Moon-worthy test plant should be ready by the mid-2020s, though, so it may just be a matter of time before explorers are producing air far from Earth.
