Astronomers leverage Starlink decay to build real-time atmospheric barometer
An astronomer is utilizing the orbital decay of Starlink satellites to create a 'planetary barometer' that measures Earth's upper atmospheric density. By tracking how quickly satellites sink due to atmospheric drag, researchers can generate real-time data on space weather conditions. This method addresses significant inaccuracies in current orbit prediction models and enhances collision avoidance capabilities in increasingly crowded low Earth orbit.
