Watch a Soyuz rocket launch dozens of OneWeb internet satellites early Thursday

The internet satellite provider OneWeb is poised to launch a new fleet to join its growing megaconstellation in orbit early Thursday (Oct. 14) and you can watch the liftoff live.

The OneWeb satellites will ride to space atop a Russian-built Soyuz rocket operated by French company Arianespace, which is scheduled to lift off from Baikonur Cosmodrome in Kazakhstan Thursday at 5:40 a.m. EDT (0940 GMT). You can watch the action live on this page, courtesy of Arianespace, or directly via the company. 

The spacecraft will deploy from the Soyuz into a near-polar orbit with an altitude of 280 miles (450 kilometers), Arianespace representatives wrote in a mission description. These deployments will occur in four-satellite batches, the last of which will take place about 3 hours and 51 minutes after liftoff.

The solar-powered satellites will then make their own way to their operational orbit, which lies 746 miles (1,200 km) above Earth. They’ll have lots of company up there; the constellation already consists of 322 spacecraft, all of which were lofted by Arianespace.

And many more will join this group over the coming weeks and months. The London-based OneWeb is building a constellation of 648 satellites, which will beam broadband internet service to people around the globe.

“Once deployed, the OneWeb constellation will enable user terminals that are capable of offering 3G, LTE, 5G and Wi-Fi coverage, providing high-speed access globally — by air, sea and land,” Arianespace representatives wrote in the mission description.

OneWeb plans to start providing such service to northern regions of the planet by the end of this year, with global coverage expected to follow in 2022.

The company will have some competition for this product. For example, SpaceX has already launched more than 1,700 of its Starlink broadband satellites (with many more the come) and is currently beta-testing the network’s service. And Amazon plans to loft its own internet-satellite constellation, though none of these spacecraft have left the ground to date.
