Chandrayan II

  • Chandrayaan II is an advanced version of the previous Chandrayaan-1 mission.
  • It has been developed indigenously by ISRO.
  • It consists of an orbiter, lander and rover configuration.
  • It is planned to be launched as a composite stack into the earth parking orbit (EPO) of 170 X 18,500 km by GSLV-Mk II.
  • The wheeled rover will move on the lunar surface and will pick up soil or rock samples for on-site chemical analysis. The data will be relayed to Earth through the Chandrayaan-2 orbiter.
  • The mission includes soft-landing on Moon and moving a rover on its surface. All three project components will be sending data and pictures to Earth.
  • It will be ISRO’s first inter-planetary mission to land rover on any celestial body.
  • Chandrayaan-2 mission is tentatively set for January 2019.

The features of the Chandrayaan-2 mission are:

  • Chandrayaan-2 mission is a totally indigenous venture comprising of an orbiter, a lander and a rover.
  • There would be a controlled descent and the lander would soft-land on the lunar surface at a specified site and deploy a rover.
  • The rover would then move around the landing site on the lunar surface in a semi-autonomous mode as decided by the ground commands.
  • The rover will observe the lunar surface and send back the data. This data will be useful for analysis of the lunar soil.
  • The payloads will collect scientific information on lunar topography, mineralogy, elemental abundance, lunar exosphere and signatures of hydroxyl and water-ice.
  • The 3,290-kg Chandrayaan-2 will orbit the Moon and perform the objectives of remote sensing the moon.

Accomplishments of Chandrayaan-1

  • India’s first lunar probe Chandrayaan-1 was launched by the ISRO in October 2008 and operated till August 2009. 
  • The Chandrayaan-1 had confirmed the magma ocean hypothesis, which stated that the moon was once completely molten.
  • In its ten-month orbit around the moon, Chandrayaan-1 had detected titanium and had confirmed the presence of calcium.
  • Chandrayaan-1 had gathered the most accurate measurements yet of magnesium, aluminium and iron on the lunar surface.
