Terafab's real job: refilling the sky with chips that last five years

What's the story? A MegaBuilds explainer argues that the sheer size of SpaceX and Tesla's planned Terafab chip complex in Grimes County, Texas, comes down to one constraint: SpaceX told the FCC it expects each orbital data-centre satellite to last about five years. "That turns every chip launched into a consumable with an expiration date," the video says, and once the first batch retires, "every chip Texas sends up would simply replace one being retired."

The scale: The site is planned at about 100 million square feet, which the video puts at roughly 15 Pentagons of floor space. Up to 80% of Terafab's targeted 1 terawatt of yearly compute is meant for space. The video quotes Elon Musk saying "All of the fabs on Earth only provide 2% of what we need for the Terafab project", and notes that Intel signed on to the project on 7 April.

The catch: Citing ABI Research analyst Andrew Cavalier, the video says heat, radiation and repair are the three hard limits for orbital compute, and that ABI's rough model found running a GPU in space for a year costs at least 10 times more than on Earth. It also points out that SpaceX's county agreement requires only $5 billion of investment by 2030 and lets the company walk away with 30 days' notice. A small-scale version already exists: Starcloud launched a satellite with an Nvidia H100 in November 2025 and trained an AI model in orbit.
