Description: The lunar gravity field is rather lumpy and bumpy, affecting spacecraft orbits and making landing on the Moon a tricky challenge. Scientist have known the cause of the lumpy gravity since 1968, when they discovered areas of concentrations of mass or “mascons” within the Moon. But they haven’t known for sure what created these mascons. Until now.
Bios: NLSI brings together leading lunar scientists from around the world to further NASA lunar science and exploration.
Dr. Jay Melosh, a GRAIL co-investigator at Purdue University in Indiana joins NLSI podcast host Nancy Atkinson.
