ISRO postpones launch of Chandrayaan-2 mission
  • This will be the second time the mission has been postponed.
  • The ambitious mission was earlier planned to be launched in April 2018 and was later fixed for October 2019.
  • With this delay, India may lose fourth position in the world for soft-landing on the Moon to Israel as it too is planning to launch a Moon mission in December 2018.

About the Chandrayaan 2 Mission:

  • Chandrayaan-2 is India’s most challenging and India’s second mission to Moon.
  • It is an advanced version of the previous Chandrayaan-1 mission (launched in 2008) which only involved orbiting around Moon, Chandrayaan-2 is a much complicated mission as it involves an orbiter, lander and rover.
  • The mission components have been completely developed indigenously by ISRO and consists of Orbiter, Lander and Rover configuration.
  • In this mission, ISRO will for the first time attempt to land a rover on Moon’s south-pole.
  • The mission involves soft-landing on the lunar surface and the rover will walk and analyze the content on the Moon’s surface.
  • Chandrayaan 2 will be launched on board of Geosynchronous Satellite Launch Vehicle Mk III (GSLV-F10).
  • It will be ISRO’s first inter-planetary mission to land a rover on any celestial body.
  • The spacecraft (orbiter) weighs around 3,290 kg and it will orbit around Moon and perform objectives of remote sensing the Moon.
  • Once GSLV-F10 put the spacecraft in 170 km x 20,000 km elliptical orbit, the orbiter will be manoeuvred towards the 100-km lunar orbit by firing thrusters and then the lander housing the rover will separate from the orbiter.
  • The six wheeled rover will move on an unexplored lunar surface and collect soil or rock samples for on-site chemical analysis to gather scientific information on lunar topography, mineralogy, elemental abundance, lunar exosphere and signatures of hydroxyl and water-ice.
  • The data will be relayed to Earth through the orbiter.
  • The rover will move around the landing site in semi-autonomous mode as decided by the ground commands.
  • The soft-landing on the surface of the Moon will be the most complex part of Chandrayaan 2 mission.
  • Only US, Russia and China have been able to soft-land a spacecraft on the lunar surface.
