Wikipedia should update its page dedicated to the word “ambition” to include Elon Musk’s photo. The tycoon has announced a megaproject according to which his two companies SpaceX and xAI will work together to launch a constellation of one million satellites that will function as data centers in orbit. The problem is that although the idea It has its advantages, it also has an impact potentially terrible for the future of our planet.
Energy efficiency. That is the great advantage of the space data centers that Musk proposes. In space, solar panels can perform optimally without the obstacles posed by Earth’s atmosphere and climate. According to SpaceX, the reduction in the cost of launching its rockets makes space a perfect alternative for AI data centers.
The plan. He project that has been presented to the US Federal Communications Commission (FCC) consists of placing these satellites in sun-synchronous orbits between 500 and 2,000 km high. That would allow the satellites to act as interconnected nodes among themselves and also with the satellites of the Starlink network through optical laser links. The plan, of course, will have to overcome important challenges like refrigeration. Dissipating the heat generated by millions of chips in the vacuum of space is complex, since satellites act as “natural thermoses.”
And radiation, what? The problem of cosmic radiation will also have to be solved. Advanced chips are very vulnerable to processing errors caused by energetic particles. It seems that AI processors are surprisingly resistant to this type of problembut the deployment of such chips on a massive scale in space could introduce new conflicts.
On-site repair, nothing. In today’s data centers, if a problem arises, a technician can physically travel if necessary to solve it. In space, physical repair is not feasible, which would force a strategy of assuming that those chips that become functionally damaged will be completely lost. SpaceX would have to continuously launch substitutes to compensate for this “mortality” of components, which complicates logistics and costs. There are optimistic perspectives in this regard, and for some the bills do work out.
Kessler syndrome. But above all there is a latent concern in the field of space security. Launching a million new satellites into already congested orbits multiplies the probability of chain collisions, validating the theory proposal in Kessler syndrome. A single major collision could generate a cloud of debris that would take decades to clear, further threatening climate monitoring missions or even global communications. There are already ideas to “regulate orbital traffic” by coordinating it, and SpaceX has its own “situational awareness” system, Stargazeto avoid problems, but of course, no system is completely perfect.
air pollution. Without forgetting that the atmospheric impact is equally worrying. Some are estimated 25,000 Starship flightsand the re-entry of satellites that end their life cycle or die prematurely would cause metals and particles to be released into the upper atmosphere. According to experts, these chemical residues could damage the ozone layer and cause uncertain climate consequences.
You can’t see anything. The astronomers, who They had already protested about Starlinkthey will have an even bigger problem with this new idea. The threat to astronomy is clear, because given the altitude and size of these satellites, it is likely that they form a bright band visible even to the naked eye, making scientific observation difficult and even changing the way we see the sunset. Orbital computing may have advantages, but before launching it we should remember that space—especially the space we see—is a shared and finite resource.
