Google is preparing to test its artificial intelligence chips in orbit through Project Suncatcher, while SpaceX is pursuing a broader plan to build computing infrastructure in space.
Google’s first mission will carry its Tensor Processing Units (TPUs) aboard a SpaceX rocket as part of the Transporter-18 rideshare, with a target launch date of October 1, 2026. The experiment will examine whether the chips can operate reliably under radiation, extreme temperatures and other space conditions.
Google plans additional missions in 2027 to test high-bandwidth laser links between satellites. The company is also exploring heat pipes and radiative cooling, since conventional air-based cooling does not work in the vacuum of space.
The project remains an engineering experiment, not a commercial orbital data center. Its focus is on testing hardware durability, heat management and satellite communications.
SpaceX has described a much larger vision based on orbital computing satellites powered by near-continuous solar energy. The company has set targets of roughly 1 gigawatt of annual orbital AI computing capacity by the end of 2027 and 100 gigawatts by 2030, according to the source.
SpaceX has also proposed a third-generation Starlink constellation of up to 100,000 satellites. The application has been accepted for review by the U.S. Federal Communications Commission, but has not received final approval.
The concept still faces major challenges, including launch costs, cooling, maintenance, communications and reliability. Musk’s forecast that space could eventually account for all computing should be viewed as an ambition, not a verified projection.
