In a significant stride towards space sustainability, the Indian Space Research Organisation (ISRO) successfully managed the end-of-life process of its Cartosat-2 satellite, setting a high standard for space debris mitigation. Launched on January 10, 2007, this 680 kg satellite has been instrumental in providing high-resolution images for urban planning until 2019, from its sun-synchronous orbit at 635 km above Earth.

Originally expected to spend 30 years in orbit, ISRO took proactive measures to ensure Cartosat-2’s safe return to Earth much sooner. By efficiently using the satellite’s remaining fuel to lower its orbit, ISRO aligned with global guidelines aimed at reducing space debris. This move, endorsed by international space organizations, significantly minimizes collision risks, marking a critical step in ensuring the long-term sustainability of space activities.
ISRO’s meticulous planning led to Cartosat-2’s re-entry into Earth’s atmosphere on February 14, 2024, over the Indian Ocean. The operation was closely monitored by ISRO’s tracking team, using advanced radar technology at Shriharikota. This not only demonstrated ISRO’s capability in tracking but also in predicting satellite behaviors, confirming that all major components of the satellite disintegrated upon re-entry as planned.
The successful de-orbiting of Cartosat-2 exemplifies ISRO’s commitment to responsible space exploration. By adhering to international guidelines for space debris mitigation, ISRO has shown leadership in preserving the space environment. This achievement underscores the importance of planning for the end-of-life of satellites and highlights ISRO’s role as a responsible participant in global space activities.
