Live coverage: Soyuz sends Russian and two Americans to space station

NASA ground crews at the Kennedy Space Center are continuing to stack segments of the Space Launch System’s side-mounted solid rocket boosters on a mobile launch platform inside the iconic Vehicle Assembly Building.

A prototype for China’s next-generation human-rated spacecraft — flying on a test flight without astronauts — is scheduled to ride a new version of the country’s heavy-lift Long March 5 rocket into orbit this week.

The French military’s newest sharp-eyed optical surveillance satellite lifted off at 1637 GMT (11:37 a.m. EST) Wednesday from French Guiana aboard a Russian-built Soyuz launcher, marking Arianespace’s 11th and final launch of 2018. The Soyuz rocket and Fregat upper stage will place the CSO 1 spacecraft into orbit around 500 miles (800 kilometers) above Earth. Managers delayed the launch from Tuesday due to unfavorable high-altitude winds.
