Japan Tsubame, Super Low Altitude Test Satellite, is a JAXA satellite tv for pc supposed to reveal operations in very low Earth orbit (beneath 200 km), utilizing ion engines to cancel out aerodynamic drag and outfitted with sensors to find out atomic oxygen density, an publicity facility to measure materials degradation within the 200 km orbit, and a small digital camera. Initial designs had typical, although barely canted, photo voltaic panels (evaluate to the aerodynamic form and on-body photo voltaic panels of GOCE, which flew in a 255 km orbit). Low Earth Orbit” (LEO), the place many satellites reside, goes from 160km (100 miles, 525,000 toes) to 2,000km
