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.

Federal Reserve Chair Jerome Powell says he will remain on the central bank's board of governors after his current term expires next month. The announcement comes amid sustained pressure from President Trump, who has repeatedly called for Powell's removal and pushed for lower interest rates, making the question of Powell's future a focal point of debate over the Fed's independence.
