Live coverage: Proton fires into space with Eutelsat 9B

Built and financed by China, a $258 million Laotian communications satellite project launched Friday aboard a Long March 3B rocket to better connect the mountainous Southeast Asia nation and surrounding regions.

A Soyuz rocket lifted off Sunday from Vostochny Cosmodrome in Russia’s Far East with 36 internet satellites built on Florida’s Space Coast for OneWeb, bringing the company’s fleet to 182 spacecraft, more than a quarter of the way to building out a constellation of nearly 650 orbiting relay nodes. 

Arianespace is returning an Ariane 5 rocket — loaded with three U.S.-built satellites — back to its final assembly building in French Guiana to replace a suspect sensor on the vehicle that prompted officials to cancel a launch attempt Friday. Arianespace said Monday that the swap will delay the launch until around Aug. 14.
