What is Polar Satellite Launch Vehicle?
Polar Satellite Launch Vehicle is an expendable Indian launch system developed by the Indian Space Research Organisation (ISRO). It is a three-stage rocket with alternating solid and liquid propellant stages. The first stage is a solid rocket, the second is a liquid-fuelled rocket, and the third stage is a solid rocket. PSLV is launched from the Satish Dhawan Space Centre, Sriharikota.
History of Polar Satellite Launch Vehicles in India
India has a long history of using polar satellite launch vehicles (PSLV) for its satellite launches. The PSLV is a four-stage rocket designed to launch satellites into polar orbits. The first PSLV launch took place in 1993, and since then, the PSLV has been used to launch over 40 satellites into orbit.
The PSLV is a reliable launch vehicle that has been used to launch a variety of satellites into orbit. Some of the notable satellites launched on a PSLV include the Chandrayaan-1 and Mars Orbiter Mission.
The PSLV has also launched commercial satellites for companies like Google and ISRO. The PSLV is an affordable launch vehicle capable of launching satellites into high-altitude orbits.
The PSLV has also been used to launch satellites for the Indian military. The PSLV is a versatile launch vehicle that has been used to launch a variety of satellites into orbit.

What are the Variants of PSLV(Polar Satellite Launch Vehicles)
There are four variants of PSLV, which are PSLV-CA, PSLV-XL, PSLV-G, and PSLV-C35. PSLV-CA is the normal variant, while PSLV-XL is the extended variant. PSLV-G is the gravity-assisted variant, and PSLV-C35 is the current operational variant.
Why are Polar Satellite Launch Vehicles used?
Polar Satellite Launch Vehicles deliver satellites into polar orbits around Earth. A polar orbit is an orbit around Earth that passes above the Earth’s polar regions. This type of orbit is used for scientific research because it allows satellites to study the Earth’s poles.
