The Indian Space Research Organisation (ISRO) is set to embark on its latest mission to the Moon, Chandrayaan-3. The mission will be launched aboard India’s most powerful rocket, the LVM-III, from the Satish Dhawan Space Centre in Sriharikota.
Objectives of the Mission
The mission is aimed at improving our understanding of the Moon’s composition and has three main objectives: demonstrating a safe and soft landing, demonstrating the rover’s roving capabilities, and performing in-situ scientific observations. IIT Madras and ISRO to Train Indian Astronauts for Space Mission.
In-Depth Studies of the Moon
The Chandra Surface Thermophysical Experiment (ChaSTE) will measure the thermal conductivity and temperature on the lunar surface. The Instrument for Lunar Seismic Activity (ILSA) will measure the seismicity around the landing site, while the Langmuir Probe (LP) will estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA has also been accommodated for lunar laser ranging studies.
Improved Technology for Interplanetary Missions
Chandrayaan-3 consists of an indigenous Lander module (LM), Propulsion module (PM), and a Rover, with the objective of developing and demonstrating new technologies for Interplanetary missions. The lander will have the capability to soft-land at a specified lunar site and deploy the rover, which will carry out in-situ chemical analysis of the lunar surface during its mobility.
Spectral and Polarimetric Measurements from Lunar Orbit
The propulsion module will carry the lander and rover configuration to about 100 km from the lunar orbit and will have the Spectro-polarimetry of Habitable Planet Earth (SHAPE) payload to study the spectral and polarimetric measurements of Earth.
Modifications after Chandrayaan-2 Failure
ISRO has made changes to Chandrayaan-3 following the loss of the Chandrayaan-2 mission while landing on the lunar surface in 2018. The mission is designed to better navigate the terrain conditions while attempting to land and deploy the rover.
Launch Dates Yet to be Announced While the Indian space agency is yet to announce the final launch dates, it is likely to be in the second or third quarter of 2023. The world is eagerly awaiting the discoveries that Chandrayaan-3 will unravel on the lunar surface.
