BREVARD COUNTY, Fla. — United Launch Alliance is preparing to launch its first Vulcan mission for Amazon Leo from Space Launch Complex-41 Sunday afternoon.
United Launch Alliance’s Vulcan rocket entered the final minute of the countdown at Cape Canaveral with the Eastern Range reporting green conditions for launch.
In the final seconds, the rocket’s systems will complete readiness checks, the launch pad water deluge system will activate and the main engines will throttle to full power. The solid rocket motors will then ignite for liftoff.
The launch window is scheduled to open at 12:11 p.m. and run through 12:40 p.m. EST.
The mission will use ULA’s VC6L Vulcan configuration to deliver Amazon Leo satellites into low Earth orbit. Amazon’s planned broadband constellation will eventually include more than 3,000 satellites designed to provide internet service to customers beyond the reach of existing networks.
The rocket stands 215 feet tall and features six solid rocket boosters, a Centaur V upper stage and a 70-foot payload fairing.
As of 11:16 a.m., ULA reported that weather conditions at Space Launch Complex-41 remained green across the board, with another weather assessment expected ahead of launch.
