Source: Google

Google said its Project Suncatcher prototype satellite, built with Planet, reached orbit on SpaceX’s Transporter-18 rideshare and is operating as expected. Over the following weeks Google will collect data on how its TPUs handle launch stress and the radiation and temperature extremes of space, and use the results to refine designs. It describes the launch as the first step in a long-term research effort on whether space could host scalable machine-learning infrastructure, and cites a peer-reviewed paper in Joule on the research behind the mission. No power, compute or satellite-count figures were given.

Why it matters

Google is testing whether its AI chips can work in orbit, the first step in research on hosting machine-learning infrastructure in space.
