New measurements of AST SpaceMobile satellites show an average brightness seven times higher than the mitigation targets cited in the company's FCC filings, with peak brightness over 200 times above the International Astronomical Union's recommended threshold of magnitude 7. Astronomers say the findings raise fresh concerns about the impact of large satellite constellations on night-sky observations, as the company prepares further deployments.
