Overview

• Ten collision avoidance manoeuvres were executed in 2024, marking a year-on-year decline credited to refined close-approach analysis that allowed collision risks to be managed within routine orbit adjustments.
• ISRO analyzed more than 53,000 close approach alerts and revised 91 manoeuvre plans for Low Earth and Geostationary satellites to avoid post-manoeuvre conjunctions.
• Globally, 2,963 objects were placed in orbit across 261 launch attempts in 2024, while launches and fragmentation events contributed 3,665 new catalogued objects to space debris.
• By December 31, 2024, India operated 136 spacecraft—including 22 in LEO, 31 in GEO and two deep-space missions—across government, private and academic initiatives.
• Since 2010, ISRO has conducted 122 Collision Avoidance Manoeuvres and recently deorbited its POEM-3 and POEM-4 platforms to limit upper-stage debris.
