ISRO successfully maneuvers Chandrayaan-3’s Propulsion Module to Earth Orbit

New Delhi: The Indian Space Research Organisation (ISRO) successfully moved the Propulsion Module (PM) of the Chandrayaan-3 spacecraft from an orbit around the Moon to an orbit around Earth in a unique experiment. This marks a significant achievement for ISRO, demonstrating its capability to maneuver spacecraft in deep space.

The propulsion module was originally intended to be used to transport the Chandrayaan-3 lander and rover to the Moon, but after exceeding its lunar mission objectives, ISRO decided to utilize it for this experimental mission. The PM (Propulsion Module) will remain in Earth orbit for about a year, during which time ISRO will conduct various experiments to test its capabilities and gather valuable data.

The first maneuver to raise the propulsion module's orbit was performed on October 9, 2023. This maneuver successfully raised the module's apogee altitude to 5,112 kilometers from 150 kilometers. This increased the module's orbital period from 2.1 hours to 7.2 hours.

The second maneuver to transfer the propulsion module to Earth orbit was performed on November 10, 2023. This maneuver successfully changed the module's inclination to 0 degrees, which is the same inclination as Earth's orbit. This maneuver also lowered the module's perigee altitude to 250 kilometers.

The propulsion module is now in a stable orbit around Earth. It will remain in orbit for about a year, during which time ISRO will conduct a series of experiments to test the module's capabilities. These experiments will include testing the module's engines, attitude control system, and communication systems.

The successful transfer of the propulsion module to Earth orbit is a significant achievement for ISRO. It demonstrates the organization's ability to perform complex spacecraft maneuvers and its commitment to exploring new technologies.

However, ISRO's successful transfer of the PM (Propulsion Module) to Earth orbit is a testament to its expertise in spacecraft operations and its commitment to pushing the boundaries of space exploration. This experiment will provide valuable data for future deep space missions and contribute to India's growing space program.
