| Outcome | JAXA's flagship lunar orbiter, second only to LRO in scientific output. SELENE performed a controlled impact on the lunar near-side in June 2009, with the impact flash confirmed by ground telescopes. Its terrain camera produced the most complete global DEM of the Moon prior to LOLA/LRO. | China's first lunar mission and the first spacecraft of the Chang'e programme. Operated for 16 months in lunar orbit, producing a complete 3D map of the Moon. Controlled impact on the lunar near-side on 1 March 2009. Demonstrated China's deep-space navigation and communications capability. | NASA Discovery-class orbiter that characterized the tenuous lunar atmosphere (exosphere) and dust environment. LADEE's Lunar Laser Communication Demonstration achieved 622 Mbps download from lunar orbit — a record at the time. Controlled impact on the lunar far side on 17 April 2014. |
