Chandrayaan 3 – ISRO

Recently the Indian Space Research Organization (ISRO) has finalized the coordinates of the landing sites of Chandrayaan-3.

All the three possible landing sites for Chandrayaan-3 are in the south polar region of the Moon facing the Earth.

The landing site is selected on the following grounds:

  • Slope gradient of the landing site,
  • Proximity to the moon’s equator,
  • Duration of sunlight at the landing site,
  • Compatibility of radio communication with the Earth,
  • Size of the boulders in the landing site,
  • Minimal presence of pits or craters.

The prime landing site is located between the Manzius U and Boguslavsky M craters (South Pole region) on the Moon.

Chandrayaan-3 is the follow on mission of Chandrayaan-2. Its primary objective is to land a lander and rover on the high ground near the Moon’s South Pole in 2023.

Chandrayaan-3 includes Lander and Rover configuration-

  • Lander: The Lunar Surface Thermo-physical Experiment (ChaSTE) will measure thermal conductivity and temperature. The Instrument for Lunar Seismic Activity (LSA) will measure seismicity around the landing site. The Langmuir probe will estimate the plasma density and changes in it.
  • Rover: Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) have been fitted to know the elemental composition of the region around the landing site. Chandrayaan-3 will be launched on a Geosynchronous Satellite Launch Vehicle (GSLV) Mk III from Sriharikota in Andhra Pradesh. GSLV is a three stage rocket. It is powered by cryogenic engine.

Earlier Chandrayaan missions-

  • Chandrayaan-1 (2008): Successfully entered the Moon’s orbit.
  • Chandrayaan-2 (2019): Successfully launched in the year 2019 and entered the Moon’s orbit. However, its lander crashed on the lunar surface due to a software glitch.
