ISRO brings back Chandrayaan-3 Propulsion Module to Earth's orbit

Deccan Chronicle  

New Delhi: The Propulsion Module of the Chandrayaan-3 spacecraft, which was initially intended for lunar operations, was successfully returned to Earth's orbit by ISRO after exceeding its lunar mission objectives, demonstrating India's ability to not only launch objects to the Moon but also bring them back. "In another unique experiment, like the hop experiment on the Vikram Lander, the Propulsion Module of Chandrayaan-3 was moved from an orbit around the Moon to an orbit around Earth," the Indian Space Research Organisation stated in its official release. It was decided to use the available fuel in the PM to derive additional information for future lunar missions and demonstrate the mission operation strategies for a sample return mission, it stated, adding that to continue the SHAPE payload for Earth observation, it was decided to re-orbit the PM to a suitable Earth orbit. This mission plan was worked out considering collision avoidance, such as preventing the PM from crashing on the Moon's surface or entering the Earth's GEO belt at 36,000 km and orbiting below that, the ISRO stated, adding that considering the estimated fuel availability and the safety of GEO spacecraft, the optimal Earth return trajectory was designed for October 2023.
