Chandrayaan-3 Mission

News: ISRO plans to execute the Chandrayaan-3 mission in August this year.

Details:

  • The Chandrayaan-3 mission is a follow-up of Chandrayaan-2 of July 2019, which aimed to land a rover on the lunar South Pole.
  • Chandrayaan-2 consisted of an Orbiter, Lander and Rover, all equipped with scientific instruments to study the moon. The Orbiter would watch the moon from a 100-km orbit, while the Lander and Rover modules were to be separated to make a soft landing on the moon’s surface.
  • ISRO had named the Lander module as Vikram, after Vikram Sarabhai, the pioneer of India’s space programme, and the Rover module as Pragyaan, meaning wisdom.
  • The Orbiter part of the mission has been functioning normally. It is carrying eight instruments.
  • Each of these instruments has produced a handsome amount of data that sheds new light on the moon and offers insights that could be used in further exploration.
  • The subsequent failure of the Vikram lander led to the pursuit of another mission to demonstrate the landing capabilities needed for the Lunar Polar Exploration Mission proposed in partnership with Japan for 2024.
  • The lander for Chandrayaan-3 will have only four throttle-able engines. Unlike Vikram on Chandrayaan-2 which had five 800N engines with a fifth one being centrally mounted with a fixed thrust.
  • Additionally, the Chandrayaan-3 lander will be equipped with a Laser Doppler Velocimeter (LDV).
