NASA is building a compact seismometer for its upcoming Artemis 3 mission to the Moon, hoping to learn more about the internal structure of the dusty satellite from its lunar tremors.
Do not scratch your eyes: the Moon is slowly shrinking, causing quakes on its surface that complicate NASA’s plans for landing Artemis 3, the first Artemis mission that will make a crewed landing on the Moon, and more ambitious missions geared towards maintaining a prolonged human lunar presence.
