Astronomer turns sinking Starlink satellites into planetary barometer
Original: Astronomer watches Starlink satellites sinking to build a 'planetary barometer'
An astronomer is tracking the gradual orbital decay of Starlink satellites to measure density changes in the upper atmosphere, effectively turning the satellite constellation into a global 'planetary barometer'. As satellites sink, the drag they experience reveals how the thin air at their altitude expands and contracts with solar activity. Space scientists are discussing the approach as a clever reuse of existing mega-constellation telemetry for atmospheric research.
Why now: The novel idea of repurposing thousands of Starlink satellites as scientific instruments for monitoring the atmosphere is generating discussion among space and science communities.
