ISRO Releases Indian Space Situational Awareness Report (ISSAR) 2025

ISSAR 2025: Monitoring India’s Interests in a Crowded Orbit

The Indian Space Research Organisation (ISRO) has released the Indian Space Situational Awareness Report (ISSAR) 2025. The report provides a comprehensive annual overview of global space activities, satellite deployments, and the growing challenges of space debris and congestion.

Global Space Landscape in 2025

• Satellite Surge: In 2025, a record 315 successful launches were conducted globally, placing 4,198 operational satellites into orbit.

• Congestion Crisis: The report highlights extreme congestion in Low Earth Orbit (LEO), with nearly 1.6 lakh close approach alerts generated during the year to prevent potential collisions.

India's Space Assets and Safety Measures

• Indian Presence: India currently manages 144 spacecraft, including active missions like the Chandrayaan-2 Orbiter and the Aditya-L1 solar observatory.

• NETRA: ISRO’s Network for Space Objects Tracking and Analysis (NETRA) continues to be the backbone of India’s space safety, monitoring threats and performing collision avoidance maneuvers.

• Debris-Free Mission: The report emphasizes India's commitment to the Debris Free Space Mission, aiming to ensure sustainable space operations by 2030.

For TNPSC and Science aspirants, ISSAR 2025 is a critical document for understanding "Space Technology" and the geopolitical challenges of orbital management.
