Watch replay of Falcon 9 launch as seen from the press site

Rocket Lab’s light-class Electron launcher is set to take off on its fifth flight from New Zealand, aiming for a 264-mile-high (425-kilometer) orbit with DARPA’s R3D2 technology demonstration satellite.

A Falcon 9 rocket core recovered after last week’s launch of a Thai communications satellite returned to port in Florida on Thursday as SpaceX preps a separate rocket structure for tests to prove it can withstand multiple missions and mulls pricing of a previously-flown rocket, targeting a re-flight of a used booster by the end of the summer.

Blaming a technical glitch encountered during a preflight test, officials said Thursday the launch of SpaceX’s next Dragon cargo capsule to the International Space Station has been delayed to early January.
