Chandrayaan-3 mission likely to be launched in July

In News
  • A senior official of the Indian Space Research Organisation (ISRO) said recently that the Chandrayaan-3 mission is scheduled for the second week of July if things go as planned.
About Chandrayaan-3
  • Chandrayaan-3 mission carries scientific instruments to study the thermo-physical properties of the lunar regolith, lunar seismicity, lunar surface plasma environment and elemental composition in the vicinity of the landing site.
  • Chandrayaan-3 is a follow-on mission to Chandrayaan-2 to demonstrate end-to-end capability in safe landing and roving on the lunar surface. It consists of Lander and Rover configuration.
  • The propulsion module, which has Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and Polari metric measurements of Earth from the lunar orbit, would carry the lander and rover configuration till 100 km lunar orbit.
  • The Lander would have the capability to soft land at a specified lunar site and deploy the Rover which would carry out in-situ chemical analysis of the lunar surface during the course of its mobility.
  • The main function of the propulsion module is to carry the lander module from launch vehicle injection till final lunar 100 km circular polar orbit and separate it.
Significance
  • The Moon is the closest heavenly body to our planet to test space technologies for extensive space missions.
  • It also acts as a promising cosmic body to explore and achieve a better understanding of extra-terrestrial territories.
  • This encourages the advancement of technologies, inspire future scientists and promote international alliances.
  • Moreover, it provides a connection to the history of the solar system and primitive earth.
Reason
  • One key reason to target the Moon’s southern pole with Chandrayaan 3 is that it contains larger shadowed areas than the northern pole. Scientists believe that these areas on the lunar surface possibly have a permanent source of water.
  • In addition, scientists also have a keen interest in the craters present in the southern pole. They believe these cold traps may contain mysterious fossil records of the early planetary system.
