ISRO Successfully Returns Chandrayaan-3 Propulsion Module to Earth Orbit, Demonstrates Moon Return Technology

BENGALURU: In a bold showcase of India’s space capabilities, ISRO has successfully achieved the return of the Chandrayaan-3 Propulsion Module (PM) back to Earth’s orbit after outperforming its initial lunar mission objectives. This historic event follows the remarkable lunar hop by Vikram, which highlighted ISRO’s ability to reignite lunar engines and control equipment beyond its planned capabilities.

Initially launched on July 14, 2023, the Chandrayaan-3 mission aimed to demonstrate a soft lunar landing near the south polar region using the Vikram Lander and Pragyaan rover. With the successful touchdown of the Vikram Lander on August 23 and all mission objectives fulfilled, ISRO turned its focus to the surplus fuel of the PM.

Employing innovative mission strategies, ISRO extended the PM’s operational life and utilized its remaining fuel for future lunar missions. By carefully planning and maneuvering its trajectory, the PM transitioned from lunar orbit to Earth orbit, avoiding potential collisions with either the Moon or Earth’s GEO belt.

With return maneuvers initiated in October 2023, the PM completed four Moon flybys before departing the Moon’s Sphere of Influence (SOI) on November 10. Currently, it orbits Earth without posing a threat to operational satellites based on current orbit predictions.

The onboard SHAPE payload continues to operate as planned, providing valuable Earth observation data. Zonal teams have developed advanced analysis tools as part of this mission, reflecting ISRO’s commitment to advancing space exploration capabilities.

The successful repositioning of the PM extends its mission life while contributing valuable insights and capabilities for future lunar missions.
