Automated excerpt

Today, our prototype satellite for Project Suncatcher, built in partnership with Planet, launched into orbit aboard the Transporter-18 rideshare mission with SpaceX. Our team has confirmed contact with the satellite and it is operating as expected. This is the first step in a long-term research moonshot exploring whether space could one day host scalable machine learning infrastructure. Over the coming weeks, we'll gather in-orbit data on how our TPUs handle the physical stress of spaceflight and the radiation and thermal extremes of space. Our peer-reviewed paper is now available in Joule, detailing the research behind this mission.
