SpaceX cancels its mission to the ISS due to hardware issues

Just 60 seconds before it was supposed to launch for a cargo resupply mission to the ISS, SpaceX aborted the mission for its Falcon 9 rocket. This launch wouldn’t have been SpaceX’s first mission to the ISS, but the return mission would’ve involved an unprecedented attempt at safely landing the rocket on a barge out at sea. Unfortunately, an issue with the “thrust vector control actuator” forced the mission to be placed on hold.
