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
Explorer 45 The spin rate was about 7 rpm, and the spin axis lay in the spacecraft orbital plane which was approximately the same as the earth's equatorial plane. The initial local time of apogee was about 21.8 hours and the line of apsides moved around toward the sun at an initial rate of 12° per month. The satellite was operationally turned off on 30 September 1974, after approximately 3 years of successful and productive operation. Explorer 45 Explorer 45 (also called as S-Cubed A and SSS-A) was a NASA satellite launched as part of Explorers program. Explorer 45 as launched on
