Artemis Astronauts Witness Lunar Meteorite Barrage
8 Apr
Summary
- Astronauts observed six meteorite impacts on the Moon's surface.
- The meteorite strikes produced brief, white to bluish-white flashes.
- These rare observations will help estimate meteorite impact frequency.

Astronauts aboard NASA's Artemis II mission, during their recent lunar flyby, observed and documented a series of meteorite impacts on the Moon's surface. This marked a significant scientific observation, as the crew reported witnessing a total of six distinct flashes of light caused by these celestial events.
The mission commander, Reid Wiseman, described the flashes as brief, white to bluish-white pinpricks of light, lasting only about a millisecond. These observations, occurring over an approximately seven-hour period, have generated considerable excitement among scientists. The data gathered is expected to provide crucial insights into the frequency and size of meteorites impacting the Moon.
Scientists noted that such observations are infrequent and valuable for understanding lunar surface processes. Unlike Earth, where smaller meteoroids burn up in the atmosphere, lunar impacts are direct. The findings are particularly relevant for future lunar base establishment, highlighting the need for continuous monitoring of meteoroid activity.
