Japanese Lunar Exploration Program km on opposite sides of the lunar body. The penetrators were to have been braked by a small rocket at an altitude of 25 km, then free fall to the surface. They were designed to withstand a collision speed of 330 meters per second to deeply penetrate the lunar regolith. Once the penetrators are deployed, the LUNAR-A spacecraft was mission-planned to maneuver to an orbital altitude of 200 km above the lunar surface. The craft was to have carried a monochromatic imaging camera with a resolution of 30 m. It was to be Japan's first large scale lunar probe. (Hiten
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
