  • It is a four-staged launch vehicle with first and third stage using solid rocket motors and second and fourth stages using liquid rocket engines.
  • It is the first Indian launch vehicle to be equipped with liquid stages.
  • Initially, PSLV had a carrying capacity of 850 kg but has been enhanced to 1.9 tonnes.
  • The PSLV has helped take payloads into almost all the orbits in space including Geo-Stationary Transfer Orbit (GTO), the Moon, Mars and would soon be launching a mission to the Sun.
  • Between 1994 and 2019, the PSLV launched 50 Indian satellites and 222 foreign satellites for over 70 international customers from 20 countries.
  • It has a history of successful launches of payloads that include Chandrayaan-1Mars Orbiter Mission(MOM) and the space recovery mission, etc.
  • The PSLV has failed only twice in its history — the maiden flight of the PSLV D1 in 1993 and the PSLV C-39 in 2017.
