United Launch Alliance initiated the countdown for an Atlas V rocket launch to deploy 29 advanced broadband satellites for Amazon Leo.

PlanCapabilityValue 4.0May 29, 2026RT by @GewoonLukas_: RT by @GewoonLukas_: United Launch Alliance has initiated the countdown for today's launch of the Atlas V rocket to deploy 29 advanced broadband satellites into space for Amazon Leo. Our launch opportunity opens at 7:33:30 p.m. EDT (2333:30 UTC) for liftoff from Cape Canaveral Space Force Station in Florida. The launch countdown is a tightly scripted sequence of procedures and steps over the next seven hours that will complete pre-launch testing, fill the rocket with propellants and put systems into flight mode. Our live status blog begins at 4:30 p.m. EDT (2030 UTC) prior to the start of fueling operations and the livestream starts 20 minutes before launch.
