SpaceX delays Crew Dragon launch due to poor weather

Forecasts of gusty, onshore winds over Florida force reschedule to Sunday of first full mission carrying four astronauts

Nasa and SpaceX have announced a 24-hour weather delay of their planned launch of four astronauts into orbit for America's first fully fledged human mission using a privately owned spacecraft.

The liftoff time slipped from Saturday to Sunday evening due to forecasts of gusty, onshore winds over Florida - remnants of storm Eta - that would have jeopardised a return landing for the Falcon 9 rocket's reusable booster stage, Nasa officials said.
