Lunar Reconnaissance Orbiter was launched on June 18, 2009 on an Evolved Expendable Launch Vehicle (EELV). The EELV inserted the orbiter into a direct trajectory to the Moon. The orbiter used the on-board propulsion system to enter into lunar orbit. After orbiter commissioning, the orbiter entered the nominal mission orbit of 50 km. Once LRO was in the final mission orbit, the six instruments began to collect measurement data for the mission. Data collected by LRO has been described as essential for planning NASA's future human and robotic missions to the Moon. 
 
The orbiter carried a secondary payload, the Lunar Crater Observation and Sensing Satellite (LCROSS), which operated as a separate mission to observe the impact of a spent Centaur rocket released over the Moon's south pole.
