Live coverage: 400th Proton rocket takes off with Russian satellite

The first Soyuz launch from Kazakhstan carrying a full load of more than 30 Florida-built satellites for OneWeb’s broadband Internet network has slipped from December to mid-to-late January, OneWeb officials said.

A United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral today at 7:42 p.m. EST (0042 GMT) to deploy the U.S. military’s SBIRS GEO Flight 3 observatory, equipped with advanced telescopic infrared vision to spot enemy missile launches, for early warning surveillance.

Running nearly a month late because of work to repair a damaged cable, a Russian Soyuz spacecraft was primed for launch early Wednesday to carry two cosmonauts and a NASA astronaut to the International Space Station, boosting the lab’s crew back to six.
