Live coverage: Proton rocket blasts off on lengthy 15-hour mission

The next launch of a Soyuz spacecraft carrying three space station fliers has been delayed indefinitely after testing at the Baikonur Cosmodrome in Kazakhstan revealed an unspecified technical problem, the Russian space agency announced Saturday.

After several near-misses in tries to catch payload shrouds jettisoned from Falcon 9 rockets climbing into space, a high-speed boat tasked with retrieving the fairings for SpaceX to reuse has been upgraded and dispatched into the Pacific Ocean ahead of a launch Wednesday from Vandenberg Air Force in California.

A Soyuz booster vaulted into a sunset sky over French Guiana on Wednesday evening, arcing north from the jungle spaceport in South America with six satellites to inaugurate OneWeb’s global broadband network.
