Artemis II astronauts observed four to five meteor impacts on the moon far side in real time — data that landing site planners for Artemis III will actually use, not just a presidential call.

The Artemis II crew became the first humans since 1972 to observe the moon's far side during darkness, directly witnessing 4-5 meteoroid impact flashes during a solar eclipse window. This direct visual data on impact frequency provides critical ground-truth calibration for orbital sensors used to assess landing hazards for Artemis III. The mission also set a new distance record of 252,756 miles from Earth, surpassing Apollo 13's 1970 mark by approximately 4,111 miles.
The Artemis II crew spent their sixth day in space doing something nobody has done since 1972: watching the moon's far side while it was dark. What they saw was the moon getting hit.
During the six-hour survey of the lunar far side, the crew directly observed meteor impact flashes on the darkened surface, Reuters reported. CBS News confirmed the crew spotted at least four to five of these flashes. The crew was positioned behind the moon during a solar eclipse, watching the nightside. No human had directly observed meteoroid impacts on the lunar far side before.
The Trump call that made headlines lasted six minutes. "Today you have made history and made all America really proud," the president told the crew, per Reuters. "This is really big stuff," Space.com reported. The quotes are not news. They are a president being a president.
What the crew saw during that eclipse window is the actual reporting. NASA's pre-flight plan included direct visual observation of small meteoroid impacts on the lunar nightside visible to the human eye, according to Astronomy.com. The flyby placed the four astronauts at a maximum distance of 252,756 miles from Earth, about 4,111 miles beyond Apollo 13's 1970 record of 248,655 miles, with closest approach about 4,067 miles above the surface, NASA's Mission Blog reported.
The far side pass required roughly 40 minutes without contact with Earth. When asked about the communications blackout, Glover said he said a little prayer, then had to keep rolling.
The observation matters beyond the spectacle. Artemis III landing site planners need ground-truth data on how frequently small objects strike the lunar surface. Direct visual confirmation of impact frequency from orbit provides a calibration point for what orbital sensors can and cannot detect. Hansen put it plainly on a call after the eclipse window: "We saw sights no human had ever seen before, not even in Apollo". The crater proposals that came out of the flyby, naming Integrity after the Orion spacecraft and Carroll after Wiseman's late wife Carroll Taylor Wiseman, are human interest. The meteor data is engineering.
The question now is whether Orion's optical and radiation sensors logged the impacts independently. If they did, the crew's visual observations become a validated dataset. If they did not, the discrepancy between what the eye saw and what the instruments recorded is its own data point.
Artemis II launched April 1 from Kennedy Space Center in Florida. The crew is expected to return to Earth in approximately one week.
