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
Aeronomy of Ice in the Mesosphere Aeronomy of Ice in the Mesosphere The Aeronomy of Ice in the Mesosphere (AIM) is a satellite to conduct a 26-month study of noctilucent clouds (NLCs). It is the ninetieth Explorer program mission and is part of the NASA-funded Small Explorer program (SMEX). On April 25, 2007 AIM was boosted into a high polar orbit by a Pegasus-XL rocket, which was air-launched from the Lockheed L-1011 "Stargazer" aircraft operated by Orbital Sciences. The AIM satellite is a , by spacecraft, powered by two solar arrays, carrying three instruments: The noctilucent clouds AIM is to study, also known as Polar mesospheric
