ISRO Develops Debris-Removal Tech Amidst Rising Collision Risks
ISRO is working on new technologies to remove space debris. This comes as more satellites in orbit increase the risk of collisions.
Source: GNews ISRO SpaceThe Indian Space Research Organisation (ISRO) is actively developing precursor technologies for removing space debris. This initiative is crucial because the increasing number of satellite constellations, especially in Low Earth Orbit (LEO), significantly raises the risk of collisions. ISRO's efforts include research into methods for tracking, capturing, and de-orbiting defunct satellites and rocket stages. The agency aims to ensure the long-term sustainability of space activities. ISRO's focus on debris removal is part of a global effort to manage the growing problem of space junk, which poses a threat to operational satellites and future space missions. These advancements by ISRO are vital for India's continued presence and safety in space.
This news is important for competitive exams, especially for UPSC GS Paper III (Science & Technology) and SSC General Awareness. It highlights India's role in addressing global space challenges and its technological capabilities. Aspirants should understand the concept of space debris, its impact, and international efforts, including ISRO's contributions, to mitigate this issue. It also connects to topics like satellite technology and sustainable space exploration.

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 can range from tiny paint flecks to large, multi-ton objects. Space debris poses a significant threat to operational spacecraft and astronauts due to high orbital velocities.
Low Earth Orbit (LEO) is an orbit around Earth with an altitude between 160 km and 2,000 km. Most human-crewed spacecraft, including the International Space Station, and many communication and Earth observation satellites operate in LEO. It is becoming increasingly crowded due to the deployment of large satellite constellations.
ISRO, the Indian Space Research Organisation, is the national space agency of India, headquartered in Bengaluru. It was founded in 1969. ISRO is responsible for India's space program, including satellite development, launch vehicles, and planetary exploration. It operates under the Department of Space, Government of India.
Examiners often ask about India's contributions to space technology, environmental concerns in space, and the functions of ISRO. Be prepared for questions on the types of orbits and the impact of space junk on satellite operations.
Remember 'ISRO's Debris Removal' as 'I-S-R-O: I Save Rubbish Orbitally' to recall their efforts in cleaning space.
Frequently Asked Questions
What is ISRO doing to address the problem of space debris?
ISRO is developing precursor technologies for active space debris removal. This includes research into methods for tracking, capturing, and safely de-orbiting defunct satellites and rocket stages to ensure the long-term sustainability of space operations.
Why is space debris a growing concern for satellite constellations?
Space debris is a growing concern because the increasing number of satellite constellations, especially in Low Earth Orbit (LEO), significantly raises the risk of collisions. These collisions can create even more debris, threatening operational satellites and future space missions.
What are the main types of space debris?
The main types of space debris include defunct satellites, spent rocket stages, and fragments from past collisions or explosions. These objects vary greatly in size, from tiny paint flecks to large, multi-ton pieces of hardware, all posing a threat due to their high orbital velocities.
