OneWeb launches 34 more satellites for growing internet constellation

Satellite operator OneWeb lofted 34 more spacecraft today (March 21) to beef up its burgeoning broadband constellation.

The satellites launched atop a Soyuz rocket from Baikonur Cosmodrome in Kazakhstan at 1:06 p.m. EDT (1806 GMT; 10:06 p.m. local Baikonur time). All 34 spacecraft were successfully deployed into low Earth orbit by 3 hours and 45 minutes after liftoff, OneWeb representatives said.

Deployment from the Soyuz, which is operated by French company Arianespace, occurred at about 280 miles (450 kilometers) above our planet. The 325-lb. (147 kilograms) satellites will now cruise up to their operational orbit, which lies at an altitude of 745 miles (1,200 km).

This was the third launch for OneWeb, which lofted six satellites in February 2019 and 34 more last month, also aboard Soyuz rockets. And many more missions are coming: The company, which has headquarters in London and Virginia, intends to build an initial network of 650 satellites, which will provide internet service to people around the world.

That service will begin soon, if everything goes according to plan.

"OneWeb's first customer demos are scheduled for the end of 2020, and availability of commercial services, for sectors such as maritime, aviation, government and enterprise, [is] scheduled for the end of 2021," company representatives wrote in a prelaunch statement.

That statement also revealed that OneWeb had dedicated this launch to cosmonaut Alexei Leonov, who in 1965 performed the first-ever spacewalk. Leonov died in October 2019 at the age of 85.

OneWeb isn't the only company with satellite-internet ambitions, of course. SpaceX has already launched 360 spacecraft for its Starlink broadband constellation, which could eventually harbor tens of thousands of satellites. And Amazon wants to loft several thousand internet craft of its own.

Such projects are fundamentally changing the orbital population — and also, many astronomers worry, the night sky. Humanity has launched just 9,300 objects to space in all of history, according to the United Nations Office for Outer Space Affairs, and Starlink may end up dwarfing that number all by itself.
