An Answer to a Lunar Mystery: Why is the Moon’s Gravity so Uneven?
Simulations based on GRAIL data show how gravitational anomalies developed early in lunar history.
Ever since the first satellites were sent to the moon to scout landing sites for Apollo astronauts, scientists have noticed a peculiar phenomenon: As these probes orbited the moon, passing over certain craters and impact basins, they periodically veered off course, plummeting toward the lunar surface before pulling back up.
