Elon Musk's SpaceX has applied to launch one million satellites into Earth's orbit to power artificial intelligence (AI). The application claims that 'orbital data centres' are the most cost and energy-efficient way to meet the growing demand for AI computing power. Traditionally, such centres are large warehouses full of powerful computers processing and storing data, but Musk's aerospace firm argues that processing needs due to the expanding use of AI are already outpacing 'terrestrial capabilities.' These satellites would join SpaceX's Starlink network, which provides high-speed internet through thousands of small satellites—though it has faced accusations of creating congestion in space, which Musk denies. According to the application submitted to the Federal Communications Commission, the new network could comprise up to one million solar-powered satellites, providing the computer capacity needed to serve billions of users globally. Musk also stated that this venture is a step towards becoming a Kardashev II-level civilization, a theoretical concept that refers to a society capable of harnessing the energy directly from its star. The satellites would operate in low-Earth orbit at altitudes between 500-2,000 km (310-1,242 miles), and SpaceX believes they would be a greener alternative to traditional data centres, which consume significant power and water for cooling. However, experts warn of the high costs of launching hardware into orbit and the rising risk of space debris collisions affecting these satellites.
