(Update: Modules separated) Chandrayaan-3 completes all lunar bound maneuvres; gears up for key module separation

The Indian Space Research Organisation's Moon-bound spacecraft, Chandrayaan-3, has achieved a crucial milestone by entering its intended lunar orbit of 153 km x 163 km, after a flawless execution of a short-duration firing, marking the successful completion of all lunar-bound manoeuvres for the mission.

The lunar-bound maneuvers were a series of intricate orbital adjustments designed to position Chandrayaan-3 in an optimal trajectory for its safe and soft landing on the Moon's South Pole.

As readies itself for the next phase of its mission, ISRO is preparing for the separation of the Propulsion Module and the Lander Module. This highly anticipated event, scheduled for August 17, 2023, will mark a critical transition in Chandrayaan-3's journey. Once separated, the Lander Module will begin its descent towards the lunar surface and deploy the rover which will carry out in-situ chemical analysis of the lunar surface.

The Propulsion Module carries a Spectro-polarimetry of Habitable Planetary Earth (SHAPE) payload which will be operated post separation of the Lander Module. SHAPE will study the spectral and polarimetric measurements of Earth from the lunar orbit.

Chandrayaan-3's successful progress exemplifies India's growing prowess in space exploration and technology. The data collected by this mission is expected to unveil valuable insights into the moon's geological composition, enhancing our knowledge of planetary evolution.

Update

The spacecraft's Lander Module has been successfully separated from the Propulsion Module. An upcoming deboosting will allow the lander to descend to a slightly lower orbit.

The Propulsion Module, on the other hand, will continue its journey in the current orbit for months or even years.
