Q6. Discuss the major technological and operational challenges in maintaining large Low Earth Orbit (LEO) satellite constellations. Analyse how mega-constellations affect orbital safety and space sustainability. (10 M)
Difficulty Level: Medium
Reference: NIE
Why the question Mega-constellations like Starlink have rapidly expanded in Low Earth Orbit, making satellite internet a major frontier of digital infrastructure. This has simultaneously raised concerns about space congestion, collision risks, debris growth and long-term sustainability of near-Earth space. Key Demand of the question- The question demands identification of the major technological and operational challenges in maintaining large LEO constellations. It also requires analysis of how such mega-constellations impact orbital safety and the sustainability of the space environment. Structure of the Answer: Introduction Write about LEO constellations as “mass-scale space infrastructure” enabling broadband, but creating new challenges of reliability, replacement cycles and orbital crowding. Body Write on challenges such as tracking and collision avoidance, satellite reliability and short lifespan, replacement logistics, spectrum coordination, and ground network complexity. Write on sustainability impacts such as orbital congestion, debris generation risks, strain on tracking systems, disposal and de-orbit compliance, and impacts on astronomy. Conclusion Conclude with the need for space traffic management, enforceable debris norms and responsible constellation design to ensure safe and sustainable use of LEO.
