Chandrayaan-3 undergoes final deboosting, module to undergo security checks

NEW DELHI: The second and final deboosting operation of Chandrayaan-3 was carried out successfully, Indian Space Research Organisation (ISRO) said in the early hours of Sunday.

Following this, the module would undergo internal checks. The powered descent is expected to start on August 23.

Deboosting is the process of slowing down to position itself in an orbit where the orbit's closest point to the Moon (Perilune) is 30 km and the farthest point (the Apolune) is 100 km.

"The second and final deboosting operation has successfully reduced the LM orbit to 25 km x 134 km. The module would undergo internal checks and await the sun-rise at the designated landing site. The powered descent is expected to commence on August 23, 2023, around 1745 Hrs. IST," ISRO said on X (formerly Twitter).

Earlier on Friday, Chandrayaan-3's Vikram lander underwent a crucial deboosting manoeuvre and descended to a slightly lower orbit, after successfully getting separated from the propulsion module the day before.

"The Lander Module (LM) health is normal. LM successfully underwent a deboosting operation that reduced its orbit to 113 km x 157 km. The second deboosting operation is scheduled for August 20, 2023, around 0200 Hrs. IST," ISRO stated.
