2022 Satellite Launch Creates Light Pollution Concerns for Astronomers

BlueWalker3, a prototype satellite launched by AST SpaceMobile, has become one of the brightest objects in the night sky, highlighting the growing problem of satellite swarms in low-Earth orbit. With over 8,600 artificial satellites currently circling the planet and an estimated 100,000 constellation satellites expected by 2030, the lack of regulations governing outer space is causing concerns for astronomers and the environment. BlueWalker3's brightness and delayed listing in satellite catalogs after jettisoning its Launch Vehicle Adapter (LVA) pose hazards for collision avoidance and ground-based observations. Researchers urge satellite companies to conduct impact assessments and implement measures to mitigate the harm caused by their satellites.
