These are the Indiana Joneses of space junk.
Holcomb and his colleagues want to study the various states objects are left in to learn how sites on the moon and other worlds change over time—and how to preserve them for our distant descendants. “We think in deep time scales,” says Holcomb. “We’re not thinking in just the next five years. We’re thinking in a thousand years.”
That sort of research, the authors say, is still quite new. Holcomb, for instance, wants to study what happens toas a sand dune washes over it. Other planetary geoarchaeology projects might focus on what the moon’s environment has wrought upon artificial materials we’ve left on the lunar surface. “We can find out more about what happened to [castoffs] in the length of time they’ve been there,” says, an archaeologist at Flinders University in Adelaide, Australia, who also wasn’t a co-author.
The Opportunity rover now rests in the same Martian sand dunes that it once photographed. NASA officially lost contact with the long-lived robot in 2019.and subject them to forces like rocket exhaust. Gorman believes even engineers with no interest in archaeology may want to take interest in work like this. “These same processes will be happening to any new habitats built on the surface,” she says. “With the archaeological sites, we get a bit of a longer-term perspective.
The moon is the immediate focus for both this paper’s authors and other space archaeologists, and it’s easy to see why. After several decades of occasional uncrewed missions and flybys, NASA’s Artemis program promises to spearhead a mass return to the satellite’s surface. The Artemis program is slated to
