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
Drag and Atmospheric Neutral Density Explorer Drag and Atmospheric Neutral Density Explorer DANDE (or Drag and Atmospheric Neutral Density Explorer) is a 50 kg class spacecraft developed by the University of Colorado Boulder was the winner of the 5th iteration of the Air Force Research Laboratory's University Nanosat Program. Due to a failure in a spacecraft system, the ground team was uanable to actively command the satellite and spacecraft became just a passive object in Earth orbit by which some passive drag characteristics might be deduced. DANDE launched on September 29, 2013 and correctly separated from the launch vehicle. After a month of assessing spacecraft health,
