A SpaceX rocket has once again failed to launch from Nasa's Kennedy Space Center today, due to high winds.
The Falcon 9, which was supposed to carry the EchoStar 23 communications satellite into orbit, should have taken off at 5:34am GMT this morning (March 14) but the launch was cancelled just 40 minutes before the scheduled lift-off.
The mission has previously been delayed many times, having been originally scheduled to take off late last year.
Instead it will now be launched this Thursday (March 16) at 5:35am GMT. SpaceX representatives say this is the earliest available opportunity.
The launch will also be streamed live on the SpaceX website if it goes ahead, news outlet Space said.
SpaceX, which aims to commercialise space travel, faced a firestorm of criticism last September when one of its Falcon 9 rockets, carrying a $200 million Facebook satellite, exploded on the launchpad.
The explosion grounded the SpaceX fleet for four months and prompted SpaceX to undertake a root-and-branch review of its technology.
