A SpaceX rocket headed for the International Space Station was grounded at the last minute - well, technically the last two minutes.
- The launch was cancelled two minutes before liftoff due to an issue with the engine ignition system.
- The rocket was carrying four astronauts - two from the U.S., one from Russia, and one from UAE - to the ISS to replace the current crew.
- SpaceX has not announced when the next launch attempt will take place.
