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
Gill (lunar crater) pair of small craters lie along the northern rim, and Gill A intrudes slightly into the western outer rim. The interior floor is relatively level, and is marked by several craterlets. On June 11, 2009, the Japanese SELENE lunar orbiter spacecraft was deliberately crashed into the surface of the Moon to the southeast of Gill. The impact site was at selenographic coordinates 65.5 S, 80.4 E. The flash from the impact was successfully observed from Mount Abu Observatory in Guru Shikhar, India. and by the Anglo-Australian Telescope. By convention these features are identified on lunar maps by placing the letter
