SpaceX's proposal for a million-strong AI data center satellite megaconstellation would create an unprecedented category of electronic waste in orbit and the atmosphere. Given the roughly five-year lifespan of data center GPUs, about 200,000 of the 1 million proposed SpaceX AI1 satellites would be decommissioned annually. Per SpaceX's May 29 FCC filing, roughly 40,000 would deorbit and burn up, dispersing materials like aluminum through the atmosphere and potentially causing ozone depletion over decades, while the remaining 160,000 could be pushed into a distant disposal orbit, permanently removing valuable materials from Earth's material life cycle.

How many satellites would need to be decommissioned each year under SpaceX's proposed orbital AI data center constellation
Around 200,000 of the 1 million proposed SpaceX AI1 satellites would be decommissioned annually, based on a roughly five-year expected lifetime for data center GPUs. Per SpaceX's May 29 FCC filing, about 40,000 of those would deorbit and burn up in the atmosphere each year, while the remaining 160,000 could be pushed into a distant disposal orbit instead.

What happens to the materials from satellites that burn up in the atmosphere versus those moved to disposal orbits
Satellites that deorbit and burn up disperse their materials, including aluminum, throughout the atmosphere as a diffuse contaminant that slowly settles over the globe, potentially causing unknown levels of ozone depletion over decades. Satellites instead pushed into a distant disposal orbit are permanently lost from any material life cycle, similar to reverse asteroid mining.
