Live coverage: Falcon 9 disintegrates after launch

A two-stage Northrop Grumman Antares booster lifted off Nov. 2 from the Mid-Atlantic Regional Spaceport on Virginia’s Eastern Shore with a Cygnus cargo freighter on the way to the International Space Station.

SpaceX’s first Crew Dragon spacecraft, fixed to the forward end of a Falcon 9 rocket, emerged Thursday from the company’s hangar at the Kennedy Space Center in Florida for the quarter-mile journey to its launch mount at pad 39A, where liftoff is scheduled early Saturday on a critical test flight before astronauts strap into the ship later this year.

The first launch of Orbital ATK’s redesigned Antares rocket since an engine failure doomed a mission in 2014 will likely be delayed more than one month until August to complete analysis of data acquired during a first stage hotfire test, officials said.
