Watch live: ULA Atlas 5 rocket launches from Cape Canaveral with 29 Amazon Leo satellites

Watch live coverage of the launch of a United Launch Alliance Atlas 5 rocket with a batch of 29 satellites for Amazon's Leo internet service on Friday, May 29, 2026. Liftoff is scheduled during a 29-minute launch window that opens at 7:33 p.m. EDT (2333 UTC). The rocket will take a north-easterly trajectory on departure from Florida's Space Coast. Amazon’s LEO satellite internet constellation, originally called Project Kuiper, is designed to rival others, like SpaceX’s Starlink and Eutelsat's OneWeb. The Leo 7 mission features the most powerful Atlas 5 configuration, the 551, equipped with five solid rocket boosters from Northrop Grumman. Commentary will be provided by Spaceflight Now's Will Robinson-Smith, starting approximately one hour prior to liftoff. Videos like this are made possible by the support of our members.
