Preserving the Moon's Historic Sites Amid Lunar Exploration Surge

The Apollo landing sites sit on the moon exactly as they were left more than fifty years ago—footprints in regolith, flags, equipment, the physical evidence of humanity's first steps beyond Earth. But that stillness is about to end. Over the next several years, dozens of new missions will touch down on the lunar surface. Some are government efforts from nations that have never been to the moon before. Others are commercial ventures, companies betting that there is money to be made in lunar resources, tourism, or infrastructure. None of these newcomers will necessarily care about preserving what the Apollo astronauts left behind.

The problem is straightforward and urgent: the moon has no protection. There are no fences around the Apollo sites, no rangers, no laws that carry real enforcement power. The Outer Space Treaty of 1967, which most spacefaring nations have signed, declares that no country can claim ownership of the moon or its resources. It also says that signatories should avoid harmful contamination and preserve the moon's environment. But the treaty contains no teeth. It names no penalties, establishes no monitoring system, and offers no mechanism for one nation to stop another from damaging a historic site.

What exists instead is a kind of honor system. NASA has published guidelines asking future lunar visitors to stay at least two kilometers away from Apollo landing zones and to avoid disturbing artifacts or equipment. The guidelines are voluntary. They carry no legal weight. As more missions arrive—particularly from nations and companies with no historical stake in the Apollo program—compliance becomes less certain. A spacecraft landing near an Apollo site, or a rover driving across the terrain where astronauts once walked, could destroy irreplaceable evidence of human achievement. Dust kicked up by a landing could coat solar panels or scientific instruments left behind. Vibrations from engines could topple equipment that has stood undisturbed for decades.

The challenge extends beyond mere physical damage. The moon's surface is a scientific archive. Samples of regolith, rocks exposed by ancient impacts, and the geological record preserved in the landing sites themselves hold information about the moon's history and, by extension, the history of the inner solar system. Contamination—whether from human activity, fuel residue, or biological material—could compromise that archive forever. Once contaminated, the data is lost. There is no way to recover it.

International space agencies and policymakers have begun to recognize the problem. Discussions are underway about how to designate lunar heritage zones, areas where exploration would be restricted or heavily regulated. Some proposals suggest creating buffer zones around the Apollo sites, areas where landing would be prohibited entirely. Others call for international agreements that would bind all spacefaring nations to specific protocols for responsible lunar exploration. The challenge is that such agreements take time to negotiate, and the lunar rush is accelerating. Missions are already in development. Launch windows are being planned. By the time a formal international framework is in place, the damage may already be done.

The stakes are not merely historical or scientific. How humanity treats the moon's heritage sites will set a precedent for how we treat other worlds. If we cannot protect the places where we have already been, what does that say about our commitment to responsible exploration? The question is no longer theoretical. It is happening now, in real time, as the next generation of lunar explorers prepares to arrive.
