PSLV-C58/XPoSat Mission: Zero Orbital Debris
The culmination of this milestone occurred on March 21, when the PSLV Orbital Experimental Module-3 (POEM-3) met its “fiery end” through controlled re-entry into the Earth’s atmosphere. ISRO confirmed that the PSLV-C58/XPoSat mission effectively left zero debris in orbit, underscoring the agency’s commitment to sustainable space practices.
According to ISRO officials, the PSLV-C58 mission, which commenced on January 1, successfully completed its primary objective of deploying all satellites into their designated orbits. Subsequently, the terminal stage of the PSLV was repurposed into the 3-axis stabilised platform, POEM-3.
Innovative Technology and Collaborative Efforts
POEM-3, equipped with nine experimental payloads, facilitated technology demonstrations and scientific experiments on newly developed indigenous systems. Notably, six payloads were contributed by Non-Governmental Entities (NGEs) through the Indian National Space Promotion and Authorization Centre (IN-SPACe), underscoring collaborative efforts in advancing space exploration.
The innovative features of POEM-3, including its cost-effectiveness and adaptability for short-duration experiments, have provided a platform for academia, startups, and NGEs to conduct space-borne experiments. From electric thrusters to satellite dispensers and star-tracking, a myriad of experiments were conducted, opening new avenues for space exploration.
Advancing Space Sustainability Efforts
ISRO emphasized the critical importance of mitigating the threat posed by space debris, especially with the proliferation of small satellite constellations. Recognizing its responsibility as a space agency, ISRO reiterated its commitment to developing advanced debris tracking systems, deorbiting technologies, and responsible satellite deployment practices.
Through initiatives like POEM-3, ISRO aims to provide a cost-effective orbital experiment platform while safeguarding orbital environments for present and future space endeavors. The agency’s dedication to sustainability underscores its pivotal role in shaping the future of space exploration.
Collaborative Operations and Monitoring
The successful execution of the PSLV-C58/XPoSat mission involved coordinated efforts from various ISRO centers. The Vikram Sarabhai Space Centre (VSSC) played a leading role in conceptualizing and realizing the POEM, while spacecraft operations were conducted effectively from the mission operations complex (MOX) at ISRO Telemetry Tracking and Command Network (ISTRAC).
Monitoring and analysis of the mission’s orbital decay were facilitated by ISRO’s System for Safe and Sustainable Spacecraft Operations Management (IS40M). Ground stations, including ISTRAC and the Multi-Object Tracking Radar (MOTR) at Shriharikota, tracked the mission’s progress until near re-entry.

A Leap Towards Sustainable Space Exploration
ISRO’s successful accomplishment of a zero orbital debris mission marks a significant leap forward in space exploration technology and sustainability efforts. By leveraging innovative platforms like POEM-3 and fostering collaboration with external entities, ISRO demonstrates its commitment to advancing space exploration while ensuring environmental responsibility.
As the agency continues to pioneer advancements in space technology, its dedication to mitigating the risks associated with space debris underscores its role as a global leader in space exploration and sustainability. Through ongoing initiatives and collaborative endeavors, ISRO aims to pave the way for a safer and more sustainable future in space exploration.
With this achievement, ISRO sets a precedent for responsible space exploration, inspiring other space agencies and stakeholders to prioritize sustainability in their missions. As humanity ventures further into the cosmos, the lessons learned from missions like PSLV-C58/XPoSat serve as guiding principles for preserving the integrity of space environments for generations to come.
