Elon Musk's SpaceX launched its sixth Starship test flight to space on Tuesday from Texas, eyeing an array of improvements on the rocket as U.S. President-elect Donald Trump watched in person, Paralel.Az reports citing Reuters.

The roughly 400-foot-tall (122-meter-tall) rocket system, designed to land astronauts on the moon and ferry crews to Mars, lifted off at 4 p.m. CT (2200 GMT) from SpaceX's sprawling rocket development site in Boca Chica, Texas.

The first stage, called Super Heavy, unexpectedly made a splashdown in the Gulf of Mexico instead of attempting to return to its launchpad, indicating something went wrong.

Starship, in space, will travel around Earth for a planned daytime splashdown in the Indian Ocean some 90 minutes later.
