UPDATE, 3:15 p.m. ET: United Launch Alliance says the Vulcan suffered an anomaly about 10 minutes into flight and failed to deliver the 40 Amazon Leo satellites to orbit. ULA confirmed the failure in a statement issued about 50 minutes after liftoff, saying it will work closely with Amazon and other organizations to find the cause, determine the corrective action and return to flight as quickly as possible. The company said it does not yet have the data to say what went wrong. It was the first total mission failure for ULA since the company was formed in 2006, and the flight was Vulcan’s first in nine months, its return to flight after a booster problem on a February national security mission. NASA Administrator Jared Isaacman offered his agency’s assistance with the investigation. The liftoff clip below shows the launch as it happened, before the anomaly.
United Launch Alliance’s Vulcan rocket lifted off from Cape Canaveral, Florida, at 12:40 p.m. ET on Sunday, November 15, 2026, on the Leo 1 mission, carrying 40 satellites for Amazon Leo, Amazon’s broadband internet constellation.
The launch had first been targeted for 12:11 p.m. ET, but the count was held before the range went green for a final attempt inside the afternoon window. Zark News carried the United Launch Alliance webcast live, and this 45-second clip follows the last ten seconds of the count, ignition and liftoff, the rocket clearing the tower, and the first seconds of ascent, through the roll maneuver call from mission control. The six solid rocket boosters separated a little over a minute and a half into the flight.
Amazon Leo is being built to bring fast, reliable internet to communities beyond the reach of existing networks, and the 40 satellites on this flight join a growing constellation already taking shape in orbit. Vulcan, ULA’s newest heavy-lift rocket, flew the mission from Space Launch Complex 41 at Cape Canaveral Space Force Station, climbing through a clear Florida sky as thousands watched the webcast live. The full webcast replay stays on the Zark News live page for this launch, and the liftoff clip above is cut from that official United Launch Alliance broadcast.
