Two geostationary communications satellites for India’s space agency and a Malaysian company will rocket into orbit from the jungle of South America on Wednesday...

OneWeb working with Arianespace, who owes the satellite internet firm six more Soyuz launches, to find a ride to orbit for more than 200 of its spacecraft left grounded by an embargo on Western payloads flying aboard Russian rockets. But with launch capacity constrained outside of China and SpaceX, a major OneWeb competitor, the commercial satellite internet provider is facing an inevitable delay in completing its constellation.

Russia's space agency said Wednesday it will not launch a batch of 36 OneWeb satellites this week unless the UK government gives up its stake in the satellite internet company, a prospect the UK business secretary later confirmed won't happen.

The James Webb Space Telescope slipped into orbit around a point in space nearly a million miles from Earth Monday where it can capture light from the first stars and galaxies to form in the aftermath of the Big Bang.

Thirty days outbound from Earth, the James Webb Space Telescope will slip into its parking orbit a million miles away Monday, an ideal spot to scan the heavens in search of faint infrared light from the first generation of stars and galaxies.

Still cruising toward its operating orbit nearly a million miles from Earth, the $10 billion James Webb Space Telescope completed a transformation into its final dimension Saturday with the last of some 50 post-launch deployments, the unfolding of the observatory's 21.3-foot (6.5-meter) primary mirror. Many engineers considered it the most complicated series of spacecraft deployments ever attempted.

The primary mirror of NASA’s James Webb Space Telescope unfolded into place Jan. 8, completing the major steps in the post-launch deployment of the giant observatory.

One of the two wings holding three of the James Webb Space Telescope’s gold-coated mirror segments folded into place Friday, setting the stage for positioning of the other wing Saturday to complete the nearly $10 billion observatory’s major deployments.

After its most active year in two decades capped by the launch of the James Webb Space Telescope for NASA, Arianespace is heading into a period of transition in 2022 marked by the introduction of new vehicles and a changing mix of customers.
