The Lunar Atmosphere and Dust Environment Explorer (LADEE) was a robotic mission that, from low lunar orbit, gathered detailed information about the lunar atmosphere, conditions near the surface and environmental influences on lunar dust. LADEE was launched in September 2013 and carried out lunar orbital operations for 223 days, concluding when the spacecraft was decommissioned by impact into the moon in April 2014.
