SELENE lunar exploration missions or lunar outpost construction on the Moon between 2018 and 2025. SELENE SELENE (; Selenological and Engineering Explorer), better known in Japan by its nickname , was the second Japanese lunar orbiter spacecraft following the Hiten probe. Produced by the Institute of Space and Astronautical Science (ISAS) and the National Space Development Agency (NASDA), the spacecraft was launched on September 14, 2007. After successfully orbiting the Moon for a year and eight months, the main orbiter was instructed to impact on the lunar surface near the crater Gill on June 10, 2009. The orbiter's nickname, Kaguya, was
Far Ultraviolet Spectroscopic Explorer (410 nmi) in altitude, with an inclination of 25 degrees and just less than a 100-minute orbital period. Its Explorer designation is Explorer 77. On 12 July 2007, "FUSE" final reaction wheel, which is required for accurately pointing a spacecraft, failed and efforts to restart it were unsuccessful. An announcement was made on 6 September that because the fine control needed to perform its mission had been lost, the "FUSE" mission would be terminated. Although the original specification was to have a Wolter-type grazing incidence telescope, the final design of the "FUSE" telescope comprises four individual mirrors. Each of the
