Astronomers say AST SpaceMobile satellites far exceed brightness limits

Astronomers report that new measurements show satellites averaging seven times brighter than mitigation targets cited in FCC filings, with peak brightness more than 200 times above the International Astronomical Union's recommended threshold. The findings raise concerns as AST SpaceMobile prepares further deployments that could worsen light pollution affecting ground-based astronomy.
Why now: AST SpaceMobile's expected deployment of more satellites is renewing debate over their impact on astronomical observations.
