    The part I find wilder than cooling is the formation flying. If I remember their paper right, it's 81 satellites inside a 1 km radius, neighbours 100 to 200 m apart, because the optical links only get datacenter bandwidth over short distances. The ISS is about 110 m across, so that's satellites roughly an ISS-length apart, all doing 7.5 km/s
