Mysterious Cold Spots on the Moon: A New Class of Impact Craters
Location: Geology 3656
Mapping by the Lunar Reconnaissance Orbiter revealed areas having unusually low temperatures called “cold spots”; regions associated with recently formed impact craters. The cold spots identify the recently formed impact craters. Studying them improves our ability to use impact chronology to date planetary surfaces. The larger cold spot craters are candidate source craters for lunar meteorites; their formation ages are a few hundred thousand to a million years, similar to ejection ages of most lunar meteorites.
