Live coverage: Soyuz MS-14 docks at space station

In one of its final preflight tests, a SpaceX Falcon 9 rocket ignited at pad 39A in Florida for several seconds Thursday, ramping up to full throttle in an end-to-end checkout of the booster before liftoff next week on a space station resupply flight.

The 50th flight of an Indian Polar Satellite Launch Vehicle delivered 10 spacecraft from five nations into orbit Wednesday, including a new Indian radar surveillance platform and a batch of small commercial Earth observation satellites.

Two newly arrived space station astronauts, both veteran spacewalkers, suited up and ventured outside the lab complex Thursday to install additional wireless communications gear, to replace a balky camera and its pan-and-tilt mechanism and to remove two suspect hoses in the station’s ammonia coolant system.
