Live coverage: SpaceX’s next Falcon 9 rocket set for launch Sunday

SpaceX launched a Korean communications satellite from Florida on Monday aboard the company’s third Falcon 9 rocket flight of the month. Liftoff from NASA’s Kennedy Space Center occurred at 3:34 p.m. EDT (1934 GMT), and the Falcon 9’s first stage landed on a floating barge in the Atlantic Ocean a few minutes later.

The Russian Soyuz MS-03 crew transport spacecraft is launched from the Baikonur Cosmodrome with three passengers on a two-day trek to the International Space Station.

An electrical problem on one of the Ariane 5 rocket’s two solid rocket boosters led to an on-pad launch abort Tuesday, likely delaying liftoff with two U.S.-built communications satellites until around the end of September, Arianespace officials said.
