ULA delays Vulcan rocket launch at Cape Canaveral after 'power interruption'

CAPE CANAVERAL, Fla. - United Launch Alliance has delayed the launch of its Vulcan rocket after a power interruption at a plant that pumps fuel into the rocket. 

The launch was initially scheduled for Friday, but, hours before the launch window opened, it encountered an issue.

ULA said power interruption was detected at the Air Liquide gaseous nitrogen plant, resulting in the loss of high-pressure pumps.

The launch has been rescheduled to lift off from Launch Complex 41 at Cape Canaveral Space Force Station on Saturday during a launch window that opens at 12:32 p.m.

ULA Vulcan returns with Leo 1 mission

The Vulcan rocket will carry a payload of 40 Amazon Leo broadband satellites into low-Earth orbit.

This launch will mark a return for ULA's Vulcan, which has been grounded since February after it experienced a mid-flight anomaly.

How to watch the ULA Vulcan rocket launch

ULA will provide live coverage of the launch.

A livestream will be available on the company's YouTube channel.

More Vulcan launches planned

ULA said the launch is the first of 38 planned Vulcan launches for the Amazon Leo project. 

The company has launched satellites for Amazon before. ULA sent 29 Amazon Leo satellites into orbit in July, but the company used its Atlas V rocket for that mission. 

What is Amazon Leo?

Amazon is building a satellite network to compete with SpaceX's Starlink service.

Amazon Leo, formerly known as Project Kuiper, is the company's broadband satellite network that is designed to provide fast internet to customers around the world.  

The company has deployed hundreds of satellites into low-Earth orbit as it grows its network. Eventually, the network will have more than 3,000 satellites.
