Video: Atlas 5 rocket launches space station cargo mission

A NASA official said Friday that SpaceX’s Crew Dragon spacecraft could be ready to ferry astronauts Doug Hurley and Bob Behnken to the International Space Station as soon as early March, pending the results from a major demonstration of the ship’s launch abort system this weekend, a pair of parachute drop tests, and space station crew schedules.

SpaceX’s launch team fueled up a Falcon 9 rocket on a California launch pad Thursday, fired the booster’s nine Merlin engines, and passed a key preflight test for the first time since a Falcon 9 exploded during a similar practice countdown in September.

NASA is moving forward with a crucial test-firing of the core stage of the first Space Launch System heavy-lift rocket as soon as Jan. 17 after engineers were satisfied with the results of a fueling test last month.
