• Google launched four TPUs into low Earth orbit.
• Project Suncatcher tests AI chips in space.
• The project aims to study technical requirements for running machine learning infrastructure on satellites.
• Google estimates satellites can generate up to eight times more solar power than comparable ground installations.

This experiment may indicate Google's interest in developing alternative infrastructure models for data centres, which could potentially reduce energy consumption and costs. The use of AI chips in space suggests a focus on scalable machine learning infrastructure, which could have significant implications for the future of computing.
