<P> The GRAIL mission consisted of two small spacecraft: GRAIL A (Ebb), and GRAIL B (Flow). They were launched on 10 September 2011 on board a Delta II rocket . GRAIL A separated from the rocket about nine minutes after launch, and GRAIL B followed about eight minutes later . 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 17 December 2012 . </P> <P> LADEE was launched on 7 September 2013 . The mission ended on 18 April 2014, when the spacecraft's controllers intentionally crashed LADEE into the far side of the Moon, which, later, was determined to be near the eastern rim of Sundman V crater . </P> <P> On 14 December 2013 at 13: 12 UTC Chang'e 3 soft - landed a rover on the Moon . This was the first lunar soft landing since Luna 24 on 22 August 1976 . </P> <P> Progress in space exploration has recently broadened the phrase moon landing to include other moons in the Solar System as well . The Huygens probe of the Cassini--Huygens mission to Saturn performed a successful unmanned moon landing on Titan in 2005 . Similarly, the Soviet probe Phobos 2 came within 120 mi (190 km) of performing an unmanned moon landing on Mars' moon Phobos in 1989 before radio contact with that lander was suddenly lost . A similar Russian sample return mission called Fobos - Grunt ("grunt" means "soil" in Russian) launched in November 2011, but stalled in low Earth orbit . There is widespread interest in performing a future moon landing on Jupiter's Europa moon to drill down and explore the possible liquid water ocean beneath its icy surface . </P>

When was the last trip to the moon made
