United Launch Alliance and Blue Origin are expressing concerns about SpaceX's plans to launch its massive Starship rocket from Florida, filing documents with the FAA outlining potential impacts on their own operations. Blue Origin is urging limitations on the number of Starship launches, test-firings, and specific operating times. Elon Musk of SpaceX criticized Blue Origin's actions as obstructive. The FAA and SpaceX are conducting environmental reviews for Starship flights from Launch Complex 39A and Space Launch Complex 37, which may not conclude until 2025. ULA and Blue Origin are apprehensive about the environmental impact of regular Starship flights on existing launch providers at Kennedy Space Center and Cape Canaveral Space Force Station. SpaceX's ambitious launch schedule, including Starlink satellites, customer payloads, and NASA missions, raises logistical challenges and safety concerns for neighboring facilities, according to ULA. The future of Starship operations in Florida remains uncertain, pending further assessments and negotiations to mitigate potential risks.
