Astronomers report that measurements of AST SpaceMobile satellites show an average brightness seven times above mitigation targets cited in FCC filings, with peak values more than 200 times brighter than the International Astronomical Union's recommended threshold of magnitude 7. The findings raise concerns as the company prepares to deploy more satellites, with researchers warning of growing interference with ground-based astronomy.
Why now: AST SpaceMobile is expected to expand its satellite constellation, renewing debate over light pollution from large satellite networks
