Space Shuttle Grail (disambiguation) 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 most-powerful configuration of a Delta II, the 7920H-10. GRAIL A separated from the rocket about nine minutes after launch, GRAIL B followed about eight minutes later. They arrived at their orbits around the Moon 25 hours apart. The first probe entered orbit on 31 December 2011 and the second followed on 1 January 2012. The two spacecraft impacted the Lunar surface on December 17, 2012.

Caption
| - Artist's interpretation of the GRAIL tandem spacecraft above the lunar surface
- This animation shows the last three orbits of the spacecraft, with views of the impact site. The impact occurs on the night side of a waxing crescent Moon, so the view shifts from a natural color Moon to a false-color elevation map.

- LRO flies over the north pole of the Moon, where it has a very good view of the GRAIL impact. The second part of this video is the view from LRO through LAMP's slit, showing the impact and the resulting plume.

Notes
| - Range was reconfigured for omni antennae instead of tracked ones to support 99 degree azimuth.
- An issue with the rocket's propulsion system was detected while the Delta 2 rocket was drained of fuel.
- A weather balloon was released minutes before the decision point to take the latest readings of upper level winds and Air Force weather reconnaissance aircraft were aloft beginning at 7 am.
