TLDR: Terafab will produce two chip types; one for Tesla and Optimus, and a space-hardened D3 variant for orbit. Solar panels in space run five times more efficiently, making orbital AI cheaper to operate than ground-based systems. A lunar electromagnetic mass driver could slash payload launch costs from $1,200 per pound to just dollars in electricity. One entity now controls the rockets, chips, robots, and satellites needed to build an off-planet AI supply chain. Terafab, a semiconductor facility developed by Tesla, SpaceX, and xAI, has officially broken ground. Elon Musk unveiled the project Saturday night at a decommissioned power plant in Austin, Texas. The facility targets one terawatt of AI compute annually, roughly double the total electricity capacity of the United States. Around 80% of its chip output is set for space deployment. Musk framed the effort as the start of what he called a galactic civilization. Terafab’s Chip Strategy and Space-Bound AI Infrastructure Terafab will produce two distinct types of chips. One type supports Optimus robots and Tesla vehicles. The other, designated D3, is hardened specifically for space. Most of the facility’s output, roughly 80%, is directed toward orbital deployment. The remainder supports ground-based AI applications and consumer devices. Musk expects Optimus robot production to reach 10 to 100 times the volume of car manufacturing. That points to billions of chips being produced annually. The scale makes Terafab central to both commercial and space operations. No existing facility currently targets this combined level of output. Musk told the Austin audience that solar panels in space operate five times more efficiently than on Earth. Milk Road AI reported this as a central part of its cost argument for orbital AI. The most powerful AI company on Earth just announced it is leaving Earth. Elon Musk stood in a decommissioned power…
