Google's Space-Based Power Play: A New Era for AI Infrastructure

Google recently launched a prototype satellite carrying four Trillium TPUs to test their durability and performance in space. The satellite, part of Project Suncatcher, is not designed as a data center but rather as a survival test for these AI chips.

The primary goal of this experiment is to determine whether the chips can withstand the harsh conditions of space, including radiation and extreme temperatures. Google has already conducted some testing on Earth, where its Trillium TPUs demonstrated resistance to high levels of radiation.

However, launch remains a significant challenge for these components, with sustained acceleration up to 10 times the force of gravity during liftoff. This is in addition to individual chips facing forces of 50 to 100 g.

The real story behind this development is not about pushing AI compute into space but rather addressing a pressing concern, power availability on Earth. With launch costs expected to drop below $200 per kilogram by the mid-2030s, Google sees an opportunity to leverage near-constant sunlight in low Earth orbit for generating solar power.

This could potentially solve one of the hard limits on AI growth: energy consumption. Google's research suggests that construction costs could become comparable to those of some equivalent facilities on Earth.
