The American space agency Nasa has deployed its new rocket system for the first time at the Cape Canaveral spaceport.

The huge rocket left the assembly hall of the Kennedy Space Center in the US state of Florida on Thursday with a special transporter.

NASA estimated eleven hours for the six-kilometer journey to launch pad 39B.

About 10,000 people gathered to watch the maneuver.

"Ladies and gentlemen, here is the most powerful rocket ever," Nasa boss Bill Nelson presented the rocket to the crowd.

Together with an Orion space capsule, the rocket is 98 meters high, higher than the Statue of Liberty in New York.

The rocket is scheduled to undergo a series of tests on the launch pad for about two weeks.

Then a dress rehearsal of the processes before the rocket launch is planned.

For this purpose, the rocket is to be refueled with three million liters of fuel on April 3rd, but the engines are not to be switched on.

With the final draining of the fuel, a safe take-off abort should then be practiced.
