Scientists found 1,114 new Moon ridges, proving recent tectonic activity and posing moonquake risks for Artemis missions.
Smithsonian scientists have identified 1,114 new small mare ridges on the Moon, bringing the total to 2,634, with an average age of 124 million years.
These features, formed by the Moon’s ongoing contraction as it cools, indicate recent tectonic activity and a shared origin with lobate scarps.
The findings confirm the Moon is still geologically active, with potential moonquake risks in the maria—key areas for future Artemis missions—highlighting the need to account for seismic hazards in site selection and mission planning.
