Summary

Story summary

Researchers have created the first global map of small mare ridges on the Moon, published in Planetary Science Journal.
The study finds ridges are young features formed by tectonic activity and resemble lobate scarps in the lunar highlands.
Findings indicate moonquakes may occur across the lunar maria, posing risks for future missions, and NASA's Artemis program plans seismic monitoring with the Lunar Environment Monitoring Station deployed by 2028.
