The Moon has officially entered a new geological epoch defined by human influence and activity, dubbed the “Lunar Anthropocene” by scientists. This historic transition marks the first time a celestial body other than Earth has entered an epoch dominated by one species.
Humans Leave Indelible Mark on Lunar Surface
For decades, humans have been observing, orbiting, and landing spacecraft on the Moon, revealing insights about its composition and structure. But now, scientists say our activities have indelibly changed the lunar surface itself.
“The Moon is no longer in a natural geological epoch,” said Martin Cullum, a planetary geologist at the University of Cambridge and co-author of a new study documenting the transition. “Human activity, including rocket launches, spacecraft crashes, and the disposal of artifacts and waste, have created a distinct stratum that will be visible in the Moon’s crust for eons.”
This new layer containing vehicle tracks, infrastructure remnants, and other debris has been dubbed the “Anthropocene lunar stratum.” It marks a turning point where human activities start to dominate geological processes.
“We have created a new epoch – the Lunar Anthropocene – based on the human record of lunar stratigraphy,” Cullum said.
Epoch Transition Linked to Artemis Missions
The transition into the Lunar Anthropocene closely coincides with NASA’s Artemis missions establishing a sustained human presence on the Moon later this decade.
“Artemis Base Camp will totally transform a part of the lunar surface,” said Alice Stewardson, a lunar geologist at MIT and lead author of the new study. “Future lunar inhabitants are going to discard materials, rearrange soil, and undertake construction projects that will leave an archaeological record comparable to early human settlements on Earth.”

|Infrastructure, vehicles, waste
|Physical disturbance of regolith, chemical changes
|Apollo landing sites
|Spacecraft remnants, tracks, tools
|Preserved historic sites documenting early lunar exploration
|Lunar polar craters
|Water mining operations
|Alteration of crater floors searching for ice deposits
These activities join the over 85,000 kg of material already on the Moon from spacecraft, including 60 abandoned human-made objects on the surface. This preexisting human litter aided scientists in defining the early Anthropocene lunar stratum.
“The Anthropocene lunar stratum is like a time capsule documenting humanity’s first off-world chapter,” Stewardson said. “It will still be there hundreds of millions of years from now when natural processes erase almost all evidence of our existence on Earth.”
Epoch Recognition Triggers Protection Measures
Recognition of the new lunar epoch has prompted calls to implement protective measures for historic artifacts and sites on the Moon.
“The Apollo 11 Tranquility Base is the first off-world archaeological site holding immense cultural significance,” said Henry Lambright, Director of the Lunar Heritage Foundation. “We must preserve and respect these extraordinary places for future generations.”
The nonprofit Moon Heritage Trust is spearheading efforts to have the six Apollo lunar landing sites designated as World Heritage Sites through UNESCO. They are also petitioning for no-fly zones around these locations to protect them from damage by landers or rovers.
“As we establish ourselves as a true multiplanetary species, we have an obligation to be worthy ancestors to those who will one day view vestiges of our presence so far from Earth,” Lambright added.
Looming Questions Over Ownership, Governance
The societal implications stretch further as the Lunar Anthropocene raises complex questions over resource rights and governance.
“Who owns the Moon? Do historical artifacts left behind confer some sovereignty?” asked Elizabeth Quinn, Director of the International Institute of Space Law. “As more countries and companies access lunar resources, we urgently need an international framework managing activities.”
Some experts argue the Moon Treaty signed in 1979 provides a foundation, stating celestial bodies should be used for peaceful purposes and prohibiting national appropriation. But with major countries like the U.S. and Russia opting not to ratify it, the treaty lacks authority.
“Governments are focused on enabling economic opportunities, but we should balance this with responsible environmental policies too,” Quinn said. With mining, tourism, infrastructure building and even advertising in space on the horizon, calls for a holistic governance strategy are mounting.
The Lunar Anthropocene offers both promise and peril. While boosting prospects for scientific discovery, economic development, and human settlement, it also poses risks of conflict, exploitation, and unintended damage. Striking the right balance could determine if humanity’s coming age in space is heroic or catastrophic.
The Road Ahead: Permanent Settlement Within 30 Years
Within just decades, the Moon may transition from hosting occasional scientific outposts to full-fledged settlements with rotating crews, families, and permanent residents.
“The Moon could realistically have over 100 inhabitants before mid-century, with the first lunar citizen possibly being born by 2050,” said Alicia Dunmore, a space architect and founder of Lunares Design. “We are designing next-generation habitats to support long-duration stays.”
Blueprints incorporate greenhouses, solar panels, regolith shielding, recreation spaces, and other amenities needed for physical and psychological wellbeing.

|Solar arrays, batteries, distribution systems
|Hydroponic systems to grow food crops
“Future lunar homes need to nurture human life just like on Earth,” Dunmore explained. “We are building communities, not just bases.”
With NASA planning a radio astronomy observatory and countries like China racing to establish research stations, activity promises to surge. Each mission expands humanity’s domains while thickening the Anthropocene layer gazing back at Earth.
Our descendants may one day regard images of untouched lunar vistas with incredulity, replaced in their imagination by sprawling settlements dotting the skies of both worlds. Perhaps no epoch shift will compare until the day starships set forth for Mars and beyond, heralding the dawn of the “Interplanetary Anthropocene.”
