After several postponements, the Space Launch System (SLS) and its capsule Orion are finally ready to take off. The NASA successfully passed the test wet dress rehearsal, a kind of dress rehearsal that goes from the filling of the tanks to the countdown. After 50 hours of testing and a small hydrogen leak, NASA confirms that everything is ready for takeoff. The SLS will return to the VAB hangar (Vehicle Assembly Building) next week.
Engineers will then have a little more time to repair the small hydrogen problem and prepare the rocket for launch. Once these preparations have been made, NASA will specify the launch date; on this subject, the American space agency will give a press conference today.
As a reminder, the Artemis 1 mission will last 1 month and will consist of sending the SLS into orbit around the Moon. Astronauts will settle in the Orion capsule from the Artemis 2 mission.
