Astronomers and many others remain deeply concerned about the instability of satellite mega-constellations, and the interference they cause to ground based science.
“Tzu-Wei Fang, a scientist at the National Oceanic and Atmospheric Administration who specializes in predicting space weather, began collaborating with SpaceX after a disastrous launch in February 2022. SpaceX watched as 38 of its 49 newly deployed Starlink satellites burst into flames. Dr. Fang’s post-mortem documented how a minor geomagnetic storm had raised the density of the air at the altitudes where low-Earth orbits take place. So instead of sailing into orbit, the Starlink satellites smacked into dense, hot air and broke apart.”
