ULA postpones Atlas V launch try
First up, ULA's Amazon Leo 5 mission is scheduled to lift off from Launch Complex 41 at 3:53 a.m., with a 29-minute launch window extending to 4:22 a.m. The Atlas V will launch to the northeast about three hours before sunrise, carrying 29 broadband satellites. No Central Florida sonic booms should occur.
However, ULA officials announced a looming threat of high winds and cumulus clouds only give this mission a 10% chance of "go for launch weather." Those forecast odds jump up to 70% during the backup launch window, which is scheduled 24 hours later.
Amazon boosts investment in Cape launch facilities
Sunday's mission will occur days after Amazon Leo officials announced plans to double the growing constellation's annual launch rate. The company has launched more than 200 satellites — and has six more stacked payloads awaiting launch at its 100,000-square-foot satellite processing facility at NASA's Kennedy Space Center.
"We’ve also invested more than $200 million in infrastructure and service upgrades at ULA launch facilities at Cape Canaveral Space Force Station in Florida. These include a dedicated vertical integration facility for Amazon Leo (VIF-A), a new rail system and second mobile launch platform to transport the stacked rocket to the pad, and a second transport ship for carrying rocket boosters from ULA's factory in Alabama to Cape Canaveral," an Amazon press release said.
"The improvements will allow ULA to double their launch capacity and reduce turnaround time between launches, benefiting Amazon Leo and other ULA government and commercial customers operating from Space Launch Complex 41," the press release said.
ULA's Amazon Leo 4 mission lifted off from Launch Complex 41 at 3:28 a.m. Dec. 16. That Atlas V with five boosters carried 27 satellites into low-Earth orbit.

ATLAS V TO LAUNCH AMAZON LEO 5


ULA's Atlas V rocket will deliver another batch of satellites into low Earth orbit for Amazon Leo, the broadband constellation. Its mission is to provide fast, reliable internet to customers around the world, including those in unserved and underserved communities, using a network of more than 3,000 LEO satellites.

(Cape Canaveral Space Force Station, Fla., March 28, 2026) – Due to predicted inclement weather, the fifth launch of the United Launch Alliance (ULA) Atlas V 551 rocket carrying the next batch of production satellites for Amazon Leo, Leo 5, has been delayed. The launch vehicle and spacecraft are healthy. A new launch date will be provided upon finalization of range approvals and deconfliction with the NASA Artemis II launch.
