Astronomer turns sinking Starlink satellites into planetary barometer

Original: Astronomer watches Starlink satellites sinking to build a 'planetary barometer'

An astronomer is tracking how Starlink satellites gradually sink in their orbits and using that data as a 'planetary barometer' to measure conditions in Earth's upper atmosphere. The idea is that changes in satellite orbital decay reveal atmospheric density, offering a novel scientific use for the thousands of SpaceX satellites in low Earth orbit.

Why now: People are discussing an unexpected scientific reuse of Starlink satellites, a subject that regularly draws attention.
