Launched on October 1, the prototype completed its commissioning checklist, including early machine learning tests. The first prompt, sent to the onboard Gemma 4 open model, produced a poem downlinked during a pass over Svalbard, Norway. Google will now test how its TPUs withstand thermal stress and radiation in orbit, ahead of twin interconnected satellites planned for 2027. The project explores powering AI compute in space.
