Live coverage: Kennedy Space Center to reopen Friday

Sierra Nevada Corp. has booked at least six launches on United Launch Alliance’s new Vulcan Centaur rocket to carry Dream Chaser supply ships into orbit on cargo runs to the International Space Station beginning in 2021, becoming the first confirmed customer for ULA’s next-generation launcher.

SpaceX is preparing for the next launch of a Falcon 9 rocket, set for blastoff from the Kennedy Space Center in Florida with the EchoStar 23 television broadcast satellite destined to cover Brazil. The rocket’s static fire test, a major milestone in any SpaceX launch campaign, was performed Thursday.

A television broadcasting satellite for Eutelsat launched Friday atop a Russian Proton rocket to begin a 15-year mission beaming TV programming into homes across Europe. The Proton rocket lifted off from the Baikonur Cosmodrome in Kazakhstan at 2220 GMT (5:20 p.m. EST) Friday.
