Home An artist’s depiction of the twin spacecraft that comprise NASA’s Gravity Recovery And Interior Laboratory (GRAIL) mission. During the GRAIL mission’s science phase, spacecraft (Ebb and Flow) transmit radio signals precisely defining the distance between them as they orbit the moon in formation.
