They also studied craters that formed when large objects smacked into the moon billions of years ago.
NASA has said the Artemis II images of craters, ridges and ancient lava flows on the moon’s surface could help scientists better understand its topography and how it formed.
The astronauts also became the first people to see a solar eclipse from the moon. Their photos showed a darkened moon as the sun slipped behind it, with only the sun’s glowing outer atmosphere visible around the edges.
