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
Fast Auroral Snapshot Explorer While its Electric Field Experiment failed around 2002, all other instruments continued to operate normally until science operations were ended on May 1, 2009. Various engineering tests were conducted afterward. Fast Auroral Snapshot Explorer The Fast Auroral Snapshot Explorer (FAST) is a NASA plasma physics satellite, and is the second spacecraft in the Small Explorer program. It was launched on August 21, 1996, from Vandenberg Air Force Base aboard a Pegasus XL rocket. The spacecraft was designed and built by NASA's Goddard Space Flight Center. Flight operations were handled by Goddard for the first three years, and thereafter were transferred
