ISRO Tackles Space Debris from LEO Satellite Constellations
ISRO is actively working to manage the increasing risk of space debris, especially from the growing number of satellites in Low Earth Orbit (LEO).
Source: GNews ISRO SpaceDr. Jitendra Singh, Union Minister of State (Independent Charge) for Science & Technology, announced that the Indian Space Research Organisation (ISRO) is taking significant steps to address the threat of space debris. This debris primarily comes from the rapidly expanding constellations of satellites in Low Earth Orbit (LEO). ISRO is developing new technologies and strategies to track, mitigate, and remove space debris. The agency recognizes that the increasing number of satellite launches by various countries and private companies poses a serious challenge to future space missions. ISRO's efforts include improving space situational awareness and collaborating internationally to ensure the long-term sustainability of outer space activities. The focus is on protecting operational satellites and preventing collisions in an increasingly crowded orbital environment.
This news is important for competitive exams under Science & Technology (UPSC GS Paper III, SSC General Awareness). It highlights India's role in global space governance and environmental sustainability in space. Aspirants should understand the concept of space debris, its risks, and mitigation strategies, as well as ISRO's initiatives in this critical area. It connects to topics like space technology, international cooperation, and environmental challenges.

Space debris refers to non-functional, human-made objects in orbit around Earth. This includes defunct satellites, spent rocket stages, fragments from explosions or collisions, and even tiny paint flecks. It poses a significant collision risk to operational satellites and spacecraft, threatening future space missions and astronauts.
Low Earth Orbit (LEO) is an Earth-centered orbit with an altitude of 2,000 km (1,200 mi) or less. It is where most artificial satellites, including the International Space Station (ISS) and many communication satellite constellations, operate. LEO is preferred for its proximity to Earth, requiring less power for communication and launch.
The Indian Space Research Organisation (ISRO) is the national space agency of India, headquartered in Bengaluru. Founded in 1969, its vision is to harness space technology for national development while pursuing planetary exploration and space science research. ISRO operates under the Department of Space (DOS), which is directly overseen by the Prime Minister of India.
UPSC and SSC often ask about ISRO's initiatives, space technology, and environmental issues in space. Questions may focus on the definition of space debris, its impact, and international efforts for mitigation.
Remember 'LEO Debris' as 'Low Orbit, Every Object is Dangerous' to recall the risk of space junk in Low Earth Orbit.
Frequently Asked Questions
What is the main challenge posed by space debris in Low Earth Orbit?
The main challenge posed by space debris in Low Earth Orbit (LEO) is the risk of collisions. These collisions can damage or destroy operational satellites and spacecraft, creating even more debris. This cascading effect, known as the Kessler Syndrome, could make certain orbital regions unusable for future missions.
How is ISRO planning to mitigate the risk of space debris?
ISRO is planning to mitigate space debris risk by developing advanced technologies for tracking debris, improving space situational awareness, and exploring methods for active debris removal. They are also focusing on designing satellites with end-of-life disposal mechanisms and collaborating internationally on debris management protocols.
Why are LEO satellite constellations a particular concern for space debris?
LEO satellite constellations are a particular concern for space debris because they involve launching hundreds to thousands of satellites into relatively low and crowded orbits. This significantly increases the probability of collisions between active satellites and existing debris, or between the constellation satellites themselves, thereby generating more debris.
