Live coverage: SpaceX’s next Falcon 9 rocket test-fired in Florida

SpaceX called off a try Sunday to launch a package of Orbcomm communications satellites from Cape Canaveral, eyeing a better chance to land the Falcon 9 rocket’s first stage booster Monday, according to Elon Musk, the company’s billionaire founder.

With two veteran test pilots at the controls, Virgin Galactic’s SpaceShipTwo rocket plane climbed to the edge of space for the first time Thursday in a major achievement for Richard Branson’s long-sought ambition to begin regular commercial hops with space tourists, and the first piloted flight by a U.S. vehicle above an altitude of 50 miles since the last space shuttle mission in 2011.

The result of last week’s inaugural test flight of Rocket Lab’s Electron satellite launcher from New Zealand, which reached space but was unable to enter orbit, positions the company for two more demonstration missions in the coming months before the privately-operated booster enters commercial service by the end of the year, Rocket Lab’s chief executive said.
