The Polar Satellite Launch Vehicle

Polar Satellite Launch Vehicle (PSLV) is an expendable launch vehicle designed and developed by the Indian Space Research Organisation (ISRO). PSLV is capable of launching satellites into polar orbit from the Satish Dhawan Space Centre at Sriharikota. PSLV has been operational since December 1994.

It is a three-stage, solid-fueled launch vehicle capable of placing satellites into orbit. The first stage is a cryogenic engine powered by the Vikas engine. The second stage is an Solid-type engine, and the third stage is a Liquid-type engine.

The PSLV was initially used to launch satellites into orbit from the PSLV Launch Complex at Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh, India. The PSLV has since been used to launch a variety of satellites into orbit, including communication, Earth observation, and navigation satellites.

The PSLV has successfully launched more than 100 satellites into orbit, making it the most successful launch vehicle in the world. PSLV launches are highly reliable and typically occur at least once every month. There are only 4 unsuccessful PSLV launches out of 100. PSLV is also the cheapest launch vehicle to produce and send payloads in the orbit.

PSLV also launched the record breaking 100+ satellites in a single launch (which was recently broken by Spacex's Falcon 9).

PSLV is one of the most important launch vehicles of ISRO which helped ISRO in becoming a space giant.
