AST SpaceMobile’s BlueWalker 3 test satellite is seen in low Earth orbit. The satellite's large phased-array antenna that expands to nearly 700 square feet has raised concerns about the brightness of the satellite in the night sky.WASHINGTON – A prototype satellite known as BlueWalker 3 has riled the scientific community which declared this week that it, a man-made piece of communications equipment, is now one of the brightest objects visible in the night sky.
That array takes up about 690 square feet of space — and because those panels are reflective, it’s almost like BlueWalker 3 is a giant mirror continuously bouncing sunlight toward our eyes. “We are building the first and only space-based cellular broadband network designed to seamlessly connect everyday smartphones,” the AST spokesperson told Space.com. “By connecting people, we aim to alleviate poverty, spur economic development, foster a diverse digital society and save lives.”The light interferes with data collection. For instance, streaks of satellites could mask objects in the vicinity of Earth — like an asteroid, Eggl said.
