NASA is looking to develop resources on the moon that initially include oxygen and water, and eventually may expand to iron and rare earths, and has already taken steps toward excavating moon soil in 2032, a scientist said on Wednesday.
The US space agency plans to return Americans to the moon as part of its Artemis mission, including the first woman and person of color by 2025, and to learn from the mission to facilitate a trip to Mars, Reuters reported.
A key part of the mission is advancing commercial opportunities in space. The agency is looking to quantify potential resources, including energy, water and lunar soil, as a goal to attract commercial investment, said Gerald Sanders, a rocket scientist at NASA's Johnston Space Center for 35 years.
Developing access to resources on the moon will be key to cutting costs and developing a circular economy, Sanders said.
"We are trying to invest in the exploration phase, understand the resources... to (lower) risk such that external investment makes sense that could lead to development and production," he told a mining conference in Brisbane.
"We are literally just scratching the surface," he said. NASA will at the end of the month send a test drill rig to the moon and plans a larger-scale excavation of moon soil, or regolith, and a pilot processing plant in 2032.
The first customers are expected to be commercial rocket companies who could use the moon's resources for fuel or oxygen.
The Australian Space Agency is involved in developing a semi-autonomous rover that will take regolith samples on a NASA mission as early as 2026, said Samuel Webster, an assistant director at the agency.
The rover will demonstrate the collection of lunar soil that contains oxygen in the form of oxides.
Using separate equipment sent to the moon with the rover, NASA will aim to extract that oxygen, he said.
"This ... is a key step towards establishing a sustainable human presence on the moon, as well (as) supporting future missions to Mars," he said at the conference.

Muddy footprints left on a Kenyan lakeside suggest two of our early human ancestors were nearby neighbors some 1.5 million years ago.
The footprints were left in the mud by two different species “within a matter of hours, or at most days,” said paleontologist Louise Leakey, co-author of the research published Thursday in the journal Science.
Scientists previously knew from fossil remains that these two extinct branches of the human evolutionary tree – called Homo erectus and Paranthropus boisei – lived about the same time in the Turkana Basin.
But dating fossils is not exact. “It’s plus or minus a few thousand years,” said paleontologist William Harcourt-Smith of Lehman College and the American Museum of Natural History in New York, who was not involved in the study.
Yet with fossil footprints, “there’s an actual moment in time preserved,” he said. “It’s an amazing discovery.”
The tracks of fossil footprints were uncovered in 2021 in what is today Koobi Fora, Kenya, said Leaky, who is based at New York's Stony Brook University.
Whether the two individuals passed by the eastern side of Lake Turkana at the same time – or a day or two apart – they likely knew of each other’s existence, said study co-author Kevin Hatala, a paleoanthropologist at Chatham University in Pittsburgh.
“They probably saw each other, probably knew each other was there and probably influenced each other in some way,” The Associated Press quoted him as saying.
Scientists were able to distinguish between the two species because of the shape of the footprints, which holds clues to the anatomy of the foot and how it’s being used.
H. erectus appeared to be walking similar to how modern humans walk – striking the ground heel first, then rolling weight over the ball of the foot and toes and pushing off again.
The other species, which was also walking upright, was moving “in a different way from anything else we’ve seen before, anywhere else,” said co-author Erin Marie Williams-Hatala, a human evolutionary anatomist at Chatham.
Among other details, the footprints suggest more mobility in their big toe, compared to H. erectus or modern humans, said Hatala.
Our common primate ancestors probably had hands and feet adapted for grasping branches, but over time the feet of human ancestors evolved to enable walking upright, researchers say.
The new study adds to a growing body of research that implies this transformation to bipedalism – walking on two feet — didn’t happen at a single moment, in a single way.
Rather, there may have been a variety of ways that early humans learned to walk, run, stumble and slide on prehistoric muddy slopes.
“It turns out, there are different gait mechanics – different ways of being bipedal,” said Harcourt-Smith.
