Scientists use the motions of 1,200 Starlink satellites to map more precisely the upper atmosphere

Scientists at Kyoto University in Japan have used the precise and known orbits of 1,200 Starlink satellites to more precisely map the Earth s thermosphere, a layer of the atmosphere from 60 to 600 miles altitude. The Kyoto University team treated the Starlink constellation as a vast network of moving atmospheric sensors. As each satellite traveled through the thermosphere, drag
