The company waived off the launch attempt because of an issue with the launchpad’s ground system.Sunita Williams and Butch Wilmore have been stuck in space for nine months after a trip on Boeing's faulty Starliner. SpaceX called off the flight over a last-minute technical issue with the rocket's launchpad, officials said on a livestream of the launch countdown.It was not immediately clear when the next launch opportunity would be.
