Polar Satellite Launch Vehicle
The Polar Satellite Launch Vehicle, commonly known by its abbreviation PSLV, is an expendable launch system developed 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, commercially available only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO).As of 2015 the PSLV has launched 87 satellites (36 Indian and 51 foreign satellites) into a variety of orbits. Some notable payloads launched by PSLV include India's Chandrayaan-1 lunar probe, the Mars Orbiter Mission and India's first space observatory Astrosat.
