The programme incorporates lunar orbiter, impactor, soft lander and rover spacecrafts. Alba Orbital builds and designs spacecrafts and consults with those building small satellites. The company proposed launching several hundred space mirror spacecrafts into orbit closer to Earth. GSAT-29 hosts few experimental payloads to mature their technology for use in future spacecrafts. Both spacecrafts are now defunct and in heliocentric orbits. Orbital Imaging spacecrafts are designed to provide commercial Earth imaging services. Both spacecrafts would be injected into slightly different orbits. Previous searches, particularly from the STEREO spacecrafts, rule out asteroids larger than in diameter. In chronological order, spacecrafts are listed equipped with electric space propulsion. Pluto and Ceres were visited by spacecrafts for the first time. Both Voyager spacecrafts have passed through the region before the discovery of the Kuiper belt. This demonstrates that a critical technology for spacecrafts has been successfully miniaturized and commercialized. It delivers engines, stages, associated control systems and components for launch vehicle and spacecrafts. Multilayer insulation (MLI) is the most common passive thermal control element used on spacecrafts. To resolve this problem, four spacecrafts were launched.
