SPADEX (Space Docking Experiment) is an Indian Space Research Organisation (ISRO) technology mission to demonstrate autonomous docking between 2 spacecraft in orbit. The mission will involve two spacecraft (Chaser and Target) rendezvous and docking together, plus testing attitude control of the combined spacecraft under docked conditions. The Chaser and Target spacecraft will then be separated for operating other payload. The mission is critical to develop rendezvous and docking abilities for ISRO’s future human spaceflight and lunar sample return missions.
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, commercially available only from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
The Indian Space Research Organisation (ISRO) is the space agency of the Government of India headquartered in the city of Bangalore. Its vision is to "harness space technology for national development while pursuing space science research and planetary exploration."
