Future designs of our satellites will every carry dozens of TPU chips whereas orbiting the Earth in clusters. To keep up the bandwidth essential to course of AI, each satellite tv for pc has to know each its personal place and the place it sits relative to its neighbors. To do that, the satellites will talk by way of lasers.
The know-how in area already exists, however most state-of-the-art programs are optimized for low bandwidth throughout massive distances, whereas our lasers must function at very excessive bandwidth over extraordinarily brief distances. Sustaining the required connection requires extraordinary precision, just like hitting a coin-size goal from miles away whereas each factors are in movement. We’ll check our work on this in 2027 once we put two satellites in orbit.
Just the start
Exploring area as a viable location for scalable AI compute gained’t occur abruptly. It takes methodical engineering, beginning with proving our {hardware} can deal with the bodily and unpredictable realities of working in orbit. This primary launch is about seeing what works, figuring out factors of failure, and making use of these findings to future missions.
Each transformative know-how we’ve constructed at Google started with an audacious objective — and the self-discipline of working backward to unravel laborious issues all alongside the best way. As our newest moonshot heads to the launchpad, our workforce is happy to share what we study and the science driving this work ahead.
