Live coverage: Ariane 5 successful in middle-of-the-night launch

Spaceflight Now members can watch a video replay of the static fire test of a SpaceX Falcon 9 rocket before the fourth launch dedicated to deploying the company’s Starlink broadband network.

SpaceX called off the launch of a Falcon 9 rocket from Cape Canaveral on Wednesday to make sure the booster’s supply of super-chilled cryogenic liquid oxygen is cold enough to support the delivery of the 5.8-ton SES 9 commercial communications satellite to an orbit nearly 25,000 miles above Earth.

The first Soyuz launch from Kazakhstan carrying a full load of more than 30 Florida-built satellites for OneWeb’s broadband Internet network has slipped from December to mid-to-late January, OneWeb officials said.
