CAPE CANAVERAL, Fla. -- Thick clouds prompted SpaceX to call off Thursday’s planned launch of four astronauts to the International Space Station for NASA. The countdown was halted at the one-minute, 7-second mark. SpaceX's next launch attempt from Kennedy Space Center is Friday, although the weather forecast is less favorable.

The Crew 11 flight includes three fliers headed for space after reassignments in the wake of problems with Boeing's Starliner capsule.
