GRAIL

The Gravity Recovery and Interior Laboratory (GRAIL) was an American lunar science mission in NASA's Discovery Program which used high-quality gravitational field mapping of the Moon to determine its interior structure. The two small spacecraft, GRAIL A (Ebb) and GRAIL B (Flow), were launched on 10 September 2011 aboard a single launch vehicle: the…
