Large constellations of bright artificial satellites in low Earth orbit pose significant challenges to ground-based astronomy1. Current orbiting constellation have brightnesses between apparent magnitudes 4 and 6, whereas the near-infrared Ks band, they can reach magnitude 2 (ref. 2). Satellite operators, astronomers other users night sky are working on brightness mitigation strategies3,4. Radio emissions induce further potential risk radio telescopes that also need be evaluated. Here we...
Abstract Large constellations of bright artificial satellites in low Earth orbit pose significant challenges to ground-based astronomy [1]. Currently orbiting constellation have visual brightnesses between apparent magnitudes 4 and 6, satellite operators, astronomers, other users the night sky are working on brightness mitigation strategies [2,3]. Here we report outcome an international optical observation campaign a prototype satellite, AST Space Mobile’s “BlueWalker 3”. BlueWalker 3...
