Live coverage: Vega rocket launches with LISA Pathfinder

Two Russian cosmonauts and a NASA astronaut flying to the International Space Station for a fourth time lifted off Friday at 2126 GMT (5:26 p.m. EDT) from the Baikonur Cosmodrome in Kazakhstan. The trio reached the orbiting research complex less than six hours later at 0309 GMT (11:09 p.m. EDT).

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.

The Italian PRISMA Earth observation satellite is set to ride a Vega launcher into a 382-mile-high (615-kilometer) orbit Thursday night from French Guiana on a mission that will take less than one hour from liftoff until spacecraft separation.
