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
SELENE-2 SELENE-2 SELENE-2 , or the Selenological and Engineering Explorer 2, is a cancelled Japanese robotic mission to the Moon that would have included an orbiter, a lander and a rover. It was intended as a successor to the 2007 SELENE (Kaguya) lunar orbiter. The lander would have targeted lava tubes and other permanently shadowed areas, which function as cold trap volatiles such as water. Water ice could be processed by future missions to produce spacecraft propellant (LOX/H). The orbiter would have a mass of 700 kg. The lander would have a mass of 1,000 kg, and would be able to
