Artemis II Finds Fleeting Lunar Meteor Flashes That Could Shape Future Moon Bases

During its flyby of the Moon’s far side, the Artemis II crew reported four to six millisecond‑long flashes from meteor impacts on the lunar surface. Scientists will combine these observations with data from orbiters and seismometers to map impact frequencies, assess risks to future lunar bases and infrastructure, and enhance understanding of lunar geology—potentially locating fresh craters and even exposed ice near the poles. Apollo-era data show moonquakes linked to impacts, and future missions plan instruments like the Lunar Environmental Monitoring Station to pinpoint where impacts occur and how they affect the Moon.
