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 which process and store data. But Musk's aerospace firm claims processing needs due to the expanding use of AI are already outpacing terrestrial capabilities.
The satellites would join SpaceX's Starlink network in orbit, which provides high-speed internet via thousands of small satellites. Musk has previously denied that this network contributes to congestion in space.
SpaceX's proposal indicates that the new network could consist of up to one million solar-powered satellites, although there is no specified timeline for the launch.
The system aims to deliver the computational capacity necessary to serve billions of users globally and is seen as a crucial step toward becoming a Kardashev II-level civilization, capable of fully harnessing the Sun's power.
Musk stated on his social media platform, X: The satellites will actually be so far apart that it will be hard to see from one to another. Space is so vast as to be beyond comprehension. The satellites would operate in low-Earth orbit at altitudes ranging from 500 to 2,000 km.
SpaceX argues that these orbital data centres would be greener than traditional data centers, which require massive amounts of power and water for cooling.
However, experts point out that launching hardware into orbit is costly, and the infrastructure for protecting, cooling, and powering these satellites can be complex. There is also growing concern over space debris, which poses risks to both the satellites and existing spacecraft.
Alongside these advancements, astronomers have raised concerns about the effects of satellite constellations on their research, expressing that light pollution and radio interference from the Starlink network hinder their observations.
Musk, who has faced criticism over overcrowding in low-Earth orbit, continues to advocate for his vision of an extensive satellite network to support global connectivity and AI advancements.
