Reflect Orbital's night-time lighting demo draws criticism from scientists and locals

US startup Reflect Orbital simulated its space-mirror concept near Lone Pine, California, using mobile lights to mimic sunlight reflected from orbit. The company plans 50,000 satellites with 59ft mirrors, and the FCC approved an initial demo satellite for next year. Environmentalists and astronomers asked the FCC to reconsider, citing harm to sleep, wildlife and the night sky.

• FCC approved a first satellite with a 59ft mirror and 3-mile-wide beam
• Company aims for 50,000 satellites at about 400 miles altitude
