NASA research using Apollo lunar regolith data refines the Moon’s impact record and places limits on meteorite contributions to Earth’s water over geologic time.

Earlier research held that meteorite impacts from the solar system's early days were a major source of Earth's water.

Meteorite-dial timepieces aren’t just aesthetically pleasing—they also contain the secrets to the origins of life.
