Question

What is the Full Form of PSLV?

Answer 1

Hint: Polar Satellite Launch Vehicle (PSLV) was built in order to develop India’s launch on Indian Remote Sensing (IRS) satellites into the synchronous orbits. It is an expendable medium lift launch vehicle which was developed by Indian Space Research Organisation. It was commercially available only from Russian in 1993. The PSLV can also launch satellites into the Geostationary Transfer Orbit but the size should be small.

Complete answer:
Some of India's important payloads such as Chandrayaan-1 (Lunar), Mars Orbiter Mission (Mangalyaan), Interplanetary mission, Space observatory (Astrosat) were launched with the help of Polar Satellite Launch Vehicle. PSLV gained its importance in the market by providing services to small satellites and its multi satellite deployment achieved with the auxiliary payloads. PSLV has launched 328 satellites from 34 different countries till November 2020. The most beautiful part is the launch of PSLV-C37 which was held on 15th February 2017 by deploying 104 satellites in sun synchronous orbit at a time. This record was made by Russia for the highest number of satellites sent to space on a single launch.
Hence according to our question, Full form for PSLV is Polar Satellite Launch Vehicle.

Note:
Polar Satellite Launch Vehicle has stages where solid and liquid systems build alternately. Indian Space Research Organisation has foreseen a number of various PSLV serving in different missions according to their requirements. All the PSLV launches were made from Satish Dhawan Space Centre which was known as Sriharikota Range before 2002. There were totally 52 PSLV launches made till 17th December 2020 and in that 49 launches were successful with the success rate of 49% whereas two launches were outright failures and one was partially failure.
