Intelligence<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Datacentres are becoming one of the fastest-growing consumers of electricity worldwide, and <\/span><strong><a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/artificial-intelligence\/\" target=\"_blank\">artificial intelligence<\/a><\/strong><span style=\"font-weight: 400;\"> is significantly accelerating this trend.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Modern AI systems rely on large clusters of <\/span><b>graphics processing units<\/b><span style=\"font-weight: 400;\"> (GPUs) and specialised accelerators to train and deploy machine learning models.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">These systems require continuous, high-density computing, leading to enormous power consumption.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Unlike traditional datacentres that primarily support content delivery and cloud services, AI datacentres consume large amounts of energy internally.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">High-speed data exchange between servers within the same facility or across nearby facilities is essential for training large language models.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">As the adoption of generative AI expands across sectors, concerns over sustainability, carbon emissions, and grid stress are becoming increasingly prominent.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Concept of Space-Based Datacentres<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">To address these challenges, researchers are exploring the idea of placing datacentres in low-Earth orbit.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The central idea is to power datacentres entirely using solar energy available in space, where sunlight is uninterrupted and more intense than on Earth.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This approach aims to bypass terrestrial constraints such as land availability, cooling limitations, and dependence on fossil fuel-based electricity grids.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Google Research\u2019s Project Suncatcher proposes deploying clusters of satellites equipped with computing hardware that can process AI workloads in space.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">These satellites would operate in carefully choreographed orbits that maintain constant exposure to sunlight, ensuring an uninterrupted power supply through solar panels.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Technical Architecture and Design Principles<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A key feature of orbital datacentres is their reliance on dense inter-satellite communication rather than high-speed connections with Earth.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">AI workloads require extremely high internal bandwidth to allow different processors to work in parallel.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In space-based systems, this would be achieved through closely spaced satellites communicating with one another using advanced multiplexing and high-frequency links.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Since most data movement occurs within the system itself, the bandwidth required to communicate with ground stations is relatively modest.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This mirrors terrestrial AI systems, where user queries require limited bandwidth compared to internal data transfers during model training.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Engineering Challenges in Space Deployment<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Despite the conceptual promise, several technical challenges remain. One major concern is exposure to solar and cosmic radiation.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Long-term radiation can degrade semiconductor components, affecting performance and reliability.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Initial tests conducted by Google indicate that some specialised AI chips can tolerate higher radiation levels than expected, but long-duration missions still pose risks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Thermal management presents another major challenge. On Earth, datacentres rely on air or liquid cooling systems.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In space, where there is no atmosphere, dissipating heat becomes significantly more complex.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Datacentres in orbit would continuously absorb solar radiation while lacking conventional cooling mechanisms, requiring advanced heat dissipation technologies.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Maintenance is also a critical issue. Unlike terrestrial facilities, repairing or replacing faulty hardware in space is expensive and logistically difficult.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This raises concerns about system resilience and long-term operational reliability.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>Economic Viability and Cost Considerations<\/strong><\/h2>\n<ul style=\"text-align: justify;\">\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The economic feasibility of space-based datacentres depends heavily on launch costs and hardware durability.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Currently, launching equipment into orbit is expensive, but projections suggest that satellite launch costs may decline substantially in the coming decades.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Google estimates that costs could fall to around $200 per kilogram by the mid-2030s, potentially improving the commercial viability of orbital datacentres.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">However, space-based solutions must remain competitive with rapidly advancing ground-based technologies.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Improvements in renewable energy integration, cooling efficiency, and energy storage on Earth could reduce the relative advantage of orbital systems.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Past experiments, such as underwater datacentres, demonstrated technical promise but were eventually discontinued due to economic constraints.<\/span><\/li>\n<\/ul>\n<h2 style=\"text-align: justify;\"><strong>India\u2019s Interest in Space-Based Datacentres<\/strong><\/h2>\n<ul>\n<li style=\"font-weight: 400;
