The Center for Space Environmentalism filed formal opposition with the FCC to Blue Origin's plan to operate a 51,600-satellite network, demanding an environmental review of collision and night-sky impacts. The filing is real and documented — the linked comment shows the April 20, 2026 submission to the FCC. Megaconstellations of this scale do pose genuine collision risks and threaten astronomical observation, concerns shared by the International Astronomical Union and multiple observatories. What's worth knowing: the FCC process typically balances space industry growth against environmental concerns, and approval timelines for large constellations often stretch 12-18 months with public comment periods still ongoing.
