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
Japanese Lunar Exploration Program Engineering Explorer), nicknamed Kaguya after a lunar princess in the ancient Japanese folklore "The Tale of the Bamboo Cutter", is the second Japanese mission to the Moon. Launched in September 2007, it was "the largest lunar mission since the Apollo program". The mission featured three separate space craft, the main orbiter (Kaguya), the small relay satellite (Okina), and the VLBI satellite (Ouna). SELENE-2, also known as Kaguya-2, formerly known as SELENE-B, is the follow-on mission to Kaguya. SELENE-2 will consist from one large lander, which will have a small-sized rover, and if possible, will also have some penetrators inherited from
