The Chandrayaan-3 spacecraft has successfully adjusted its orbit to 153 km x 163 km, as reported by the Indian Space Research Organisation (ISRO) today. This precise maneuvering is a pivotal step as the mission gears up for its anticipated soft landing on the Moon's South Polar region on August 23.

In the days leading up to this current status, the spacecraft had undergone significant orbital changes. On August 14, during its orbit circularisation phase, the spacecraft achieved a position of 151 km x 179 km. Even earlier, on August 9, a crucial maneuver reduced Chandrayaan-3's orbit to 174 km x 1437 km.

ISRO has maintained a close watch over the progression of Chandrayaan-3 since its inception. The health of the spacecraft remains in optimal condition. Monitoring operations are spearheaded from the Mission Operations Complex (MOX) at ISRO's Telemetry, Tracking, and Command Network (ISTRAC) and the Indian Deep Space Network (IDSN) antenna at Byalalu. The partnership with the European Space Agency (ESA) and NASA's Jet Propulsion Laboratory (JPL) ensures that deep space tracking keeps Chandrayaan-3 on its desired trajectory.

Chandrayaan-3's primary mission is to demonstrate the capability of a successful soft landing on the Moon. Unlike its predecessor, Chandrayaan-2, this mission is solely equipped with a lander and a rover, forgoing an orbiter.

However, it leans on the still-operational Chandrayaan-2 orbiter for necessary data. The focus on the Moon's South Polar region is due to its potential for hosting water ice, which is seen as a vital resource for future lunar missions and possibly deep-space endeavors.

Recalling the Chandrayaan-2 mission in 2019, it had set ambitious goals with its Vikram lander and Pragyan rover. While the journey to the lunar orbit was achieved seamlessly, the Vikram lander faced challenges during its final descent stages, culminating in a hard landing.

Nonetheless, the mission's orbiter has proven to be a significant asset, offering valuable insights into the Moon's topography and mineral composition. The experiences and learnings from Vikram's landing attempt have been integral in shaping the trajectory of Chandrayaan-3.
