Mapping the moon

Two NASA probes that spent last year orbiting the moon have returned stunning new geological maps that could help explain how it, Earth, and other planets in our solar system formed. The probes, named Ebb and Flow, flew identical orbits just miles above the moon’s surface to measure its gravity field. Slight disruptions in their paths—caused by the push and […]
