Live coverage: Japanese cargo craft arrives at space station

Boeing has reshuffled a sequence of test flights planned for the company’s CST-100 Starliner capsule after stuck valves inside a test version of the ship’s service module caused a fuel spill in June, delaying the commercial spacecraft’s first unpiloted orbital demo mission until late this year or early 2019, and moving back the first crew launch to mid-2019, a company official said Wednesday.

The power and propulsion section of Orbital ATK’s next Cygnus supply ship, featuring new solar panel and fuel tank designs, arrived at NASA’s Kennedy Space Center in Florida on Wednesday to be joined with a cargo module for a Dec. 3 launch to the International Space Station.

The first Ariane 5 launch since a mission flew off course Jan. 25, deploying two communications satellites into an off-target orbit, is underway. Liftoff with the DSN 1/Superbird 8 and Hylas 4 communications satellites occurred on time at 2134 GMT (5:34 p.m. EDT).
