BREVARD COUNTY, Fla. — The launch of a United Launch Alliance Vulcan rocket carrying 40 Amazon internet satellites was delayed Friday following a power interruption at an off-site supply plant.
ULA has moved the launch to a backup window, confirming that the rocket and spacecraft remain healthy.
The mission, designated Vulcan Leo 1, was originally scheduled to lift off Friday, Nov. 13, at 12:54 p.m.
The launch is now set for 12:32 p.m. on Saturday.
The mission uses a Vulcan VC6L rocket carrying the first batch of 40 production satellites for the Amazon Leo constellation into low-Earth orbit.
This flight represents the first of 38 contracted Vulcan rockets dedicated to launching Amazon’s advanced satellites, building on nine previous successful launches using Atlas rockets.
Amazon Leo is a low Earth orbit satellite network designed to provide fast, reliable internet service to customers beyond the reach of existing networks.
The company plans to construct the full network using a constellation of more than 3,000 satellites in low Earth orbit.
Saturday’s flight will also utilize an improved nozzle design to address a solid rocket booster anomaly experienced on previous Vulcan launches.
ULA’s integrated team identified several potential contributors to the issue and mitigated them through design and process updates to the booster nozzle.
