ISRO's Orbital Safety Strategy: Tackling Space Debris with Advanced Tracking
ISRO is enhancing India's space safety by implementing new strategies to manage space debris and prevent collisions in orbit.
Source: GNews ISRO SpaceThe Indian Space Research Organisation (ISRO) has developed a robust Orbital Safety Strategy to address the growing threat of space debris. This strategy focuses on collision avoidance maneuvers and advanced tracking capabilities. ISRO's efforts are crucial as the number of operational satellites and debris fragments in Earth's orbit continues to increase, posing significant risks to active missions. The agency uses its Multi-Object Tracking Radar (MOTR) and other ground-based sensors to monitor objects in space. ISRO regularly performs collision avoidance maneuvers for its satellites, especially for critical missions like Chandrayaan and Mangalyaan. The strategy also includes designing satellites for de-orbiting at the end of their operational life, reducing future debris. ISRO is actively collaborating with international partners to share data and best practices for space situational awareness (SSA). This comprehensive approach ensures the long-term sustainability of India's space assets and contributes to global space safety.
This topic is important for competitive exams under Science & Technology (UPSC GS Paper III, SSC General Science). Aspirants should understand ISRO's role in space governance, the challenges of space debris, and India's contributions to global space safety. Questions often cover ISRO's initiatives, related technologies, and international collaborations in space.

Space debris refers to defunct human-made objects in orbit around Earth. This includes old satellites, spent rocket stages, and fragments from collisions or explosions. It poses a significant threat to operational spacecraft due to high orbital velocities, potentially causing damage or destruction.
A collision avoidance maneuver is a planned change in a satellite's orbit to prevent it from colliding with another object, such as space debris or another satellite. These maneuvers are critical for ensuring the safety and longevity of space missions.
Space Situational Awareness (SSA) involves tracking, identifying, and characterizing objects in space, both natural and artificial. It provides a comprehensive understanding of the space environment, enabling safe and sustainable space operations and predicting potential threats.
The Indian Space Research Organisation (ISRO) is the national space agency of India, founded in 1969. Headquartered in Bengaluru, its primary objective is to advance space technology and apply it for national development. ISRO is responsible for India's space program, including satellite launches, planetary exploration, and remote sensing.
Examiners frequently ask about ISRO's latest missions, its role in international space cooperation, and technological advancements in space exploration and safety. Focus on specific initiatives and their objectives.

Frequently Asked Questions
What is ISRO's strategy for managing space debris?
ISRO's strategy for managing space debris involves a multi-pronged approach. It includes performing collision avoidance maneuvers for its operational satellites, developing advanced tracking systems like MOTR, and designing satellites for controlled de-orbiting at the end of their mission life to minimize new debris generation.
Why is space debris a significant problem for space missions?
Space debris is a significant problem because even small fragments travel at extremely high velocities (tens of thousands of km/h). A collision with such debris can severely damage or destroy operational satellites, leading to loss of critical services and creating even more debris, exacerbating the problem.
How does India contribute to global space safety?
India contributes to global space safety through ISRO's active participation in international forums and collaborations on Space Situational Awareness (SSA). ISRO shares data, expertise, and best practices with other space agencies, working towards a common goal of ensuring the long-term sustainability and safety of outer space activities for all nations.
