SpaceX's 6th test launch of spacecraft...Trump is also on the lookout.

Tesla CEO Elon Musk's space company SpaceX launched the spacecraft "Starship," but the launch pad's robotic arm failed to hold onto the propellant.

In Starship's sixth test launch on Boca Chica Beach, Texas, on the 19th local time, the plan to capture the propellant was canceled four minutes after the flight, and the propellant crashed into the sea three minutes later.

U.S. President-elect Donald Trump also sat down with Musk to observe the launch.

Earlier, SpaceX tested Earth's orbit in a similar manner five times through April and November of last year, and March and June and October of this year.

During the fifth flight on the 13th of last month, the robot arm at the top of the launch pad succeeded in catching the returned first-stage propellant.
