A launch attempt on Monday or Tuesday is off the table following Saturday's large leak, NASA officials said.

NASA engineers will look at the rocket and determine if a launch window on Sept. 26 or Sept. 27 is a possibility, officials said during a Saturday press briefing.

The SpaceX launch on Oct. 5 that will send astronauts to the International Space Station will factor into the decision-making as well.

Mission management team will meet Saturday to see if there is still a possibility for a launch, or if they will have to roll back into the vehicle assembly building, NASA Administrator Bill Nelson said speaking on NASA TV.

If they decide to roll back into the vehicle assembly building, then it will be an October launch, more likely toward the middle of October.

Nelson said the launch will happen when it is ready, saying, "This is part of our space program; be ready for the scrubs."

The launch director has officially decided to scrub the launch scheduled for Saturday afternoon after NASA engineers detected several liquid hydrogen leaks.

NASA engineers encountered the leak while loading the propellant into the core stage of the Space Launch System rocket.

Multiple troubleshooting efforts to address the area of the leak did not fix the issue. NASA said engineers are continuing to gather additional data.

NASA has not yet said when it plans to make another launch attempt.

NASA engineers have detected a liquid hydrogen leak for the fourth time, despite three attempts to troubleshoot the leak. NASA said its teams are now discussing next steps.

A third leak occurred earlier in a cavity between the ground and flight side plates of a quick disconnect in the engine section. They attempted to warm up the quick disconnect to try to reset the seal then began flowing liquid hydrogen to the core stage.

NASA said the liquid oxygen tank of the core stage is full and is being replenished as some of the super-cooled propellant boils off.

Launch control gave an order for fuel loading operations for Artemis I to begin Saturday morning, ahead of the scheduled launch window.

Over the next few hours 760,000 gallons of liquid hydrogen and oxygen will be loaded into the Space Launch System (SLS) tank.

Engineers detected a liquid hydrogen leak in a quick disconnect cavity and stopped flowing the propellant to the core stage while they troubleshot, NASA had said earlier.

Launch controllers have resumed the flow of liquid hydrogen to the core stage.
