Google to Test AI Chips in Space for the First Time Next Week

Google has announced that it will conduct its first test of AI chips in space next week as part of its research project called “Project Suncatcher.” The company plans to send a prototype satellite into orbit to study whether space could eventually be used for large-scale artificial intelligence computing data centers.

The mission will be launched through SpaceX’s Transporter-18 rideshare mission. Google has partnered with satellite company Planet Labs for the project.

The satellite will carry Google’s Tensor Processing Units (TPUs), which are designed for AI computing. The test will examine how the chips perform in the harsh conditions of space, including intense radiation, extreme temperatures and the physical stress experienced during launch.

Google will also test a new cooling system for the AI chips. Traditional air-based cooling is not possible in space, so the company plans to use a system combining heat pipes and radiators to manage the heat produced by the processors.

According to Google, the AI chips have already been tested at the University of California. However, testing them in orbit will provide a more realistic assessment of how they perform in the actual space environment.

Google is not the only company exploring the idea of data centers in space. Companies including SpaceX and Starcloud are also working on concepts for establishing computing infrastructure in Earth’s orbit. The idea could allow companies to make use of continuous sunlight for energy while reducing reliance on limited electricity supplies on Earth.

Experts say that space-based data centers are still several years away from becoming commercially practical. High launch costs, complex engineering requirements and challenges in producing large numbers of satellites remain major obstacles to the development of the technology.
