There have been six lunar landings since 1969, and there are already eight more missions being planned as of this year. Some of them include rovers that will crawl over the surface of the moon for miles, studying whatever objects cross their fresh tracks. That’s good news for the space economy of the future, but bad news for preservationists. Enter For All Moonkind, a campaign to create an international agreement to preserve human artifacts in space, one similar to existing treaties such as the World Heritage Convention. Right now there is nothing protecting the more than 80 historical archaeological sites on the moon, including the Apollo 16 lander, three moon buggies, two golf balls, and the aluminum fallen astronaut sculpture that was secretly left behind by the crew of Apollo 15. The preservation effort has been slowgoing--there is currently just one benefactor on board--but the cause is worth shooting for nonetheless. In 2018, it garnered permanent observer status at the United Nations Committee on the Peaceful Uses of Outer Space.
