JAKARTA - The Orion spacecraft in one hour will ride the giant Space Launch System (SLS) rocket, making history on the Artemis I mission to the Moon.
To show it worldwide, NASA broadcasts its preparations and launches live through NASA TV's YouTube channel.
It was seen in a live broadcast how the SLS and Orion, which had the engine started first, then the Artemis I control room, further examined how the rocket was doing.
From starting to refuel, then stabilizing the engine, adjusting the rocket lane so that it can achieve its goals and others.

However, while filling the liquid hydrogen tank and liquid oxygen tank, the hydrogen refill valve leaks as the top stage is refueling.
Not long after, NASA deployed a Red Crew capable of repairing the leak by tightening the bolts on the valve. This crew is specially trained to carry out operations inside and around the tank launch vehicle.
Then the Red Crew stopped the flow of liquid hydrogen tanks due to leaks, it also stopped the disposal of the liquid hydrogen engine for 90 minutes.
After the discussion, it only took 45 minutes to stop it, now the SLS has met the launch requirements.
Meanwhile, the liquid hydrogen charging valve has been repaired and flow to the core-stage liquid hydrogen tank has resumed. The crew is simultaneously working to configure the upper stages to continue refueling.
After the leak is repaired, they then leave the runway. If nothing goes wrong again, in an hour this SLS rocket will take Orion to explore the orbit of the moon, pass the Moon and then come back again after a 25-day mission.
