The Polar Satellite Launch Vehicle (PSLV) is an expendable launch vehicle developed by the Indian Space Research Organisation (ISRO). It is designed to deploy satellites into polar orbits, making it ideal for Earth observation and remote sensing missions. The PSLV has gained recognition for its reliability and versatility, successfully launching numerous satellites for both India and other countries. Since its first flight in 1993, the PSLV has undergone several upgrades, enhancing its payload capacity and performance. It can carry payloads of up to 1,750 kilograms to a polar orbit and has been instrumental in launching various missions, including the Mars Orbiter Mission (Mangalyaan) and the Navigation with Indian Constellation (NavIC) satellites.
