Polar Satellite Launch Vehicle (PSLV)

PSLV is an expendable medium-lift launch vehicle. It has been designed and operated by the Indian Space Research Organisation (ISRO). It was developed so that India could launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits.  PSLV also launch the small size satellites into Geostationary Transfer Orbit (GTO). Some of the PSLV include India’s first space observatory called Astrosat, India’s first lunar mission called Chandrayaan-1, India’s first interplanetary mission called the Mars Orbiter Mission (Mangalyaan).
