The first mission of the Artemis program is Artemis 1. It will launch an uncrewed capsule on a journey to the moon.

There were problems with the launch of Artemis 1 on two separate occasions. The mission team replaced two seals at the site of the liquid hydrogen propellant leak and then disconnected the SLS core stage from the mobile launch tower.

The team detected a leak but was able to bring it down to manageable levels. NASA officials wrote in an update on Thursday that "teams are fine- tuning procedures for the next launch opportunity, targeted for no earlier than September 27th."

The mission team's plans will be given more detail in today's press conference.

The plans are contingent on a number of things. NASA applied for a Waiver from the U.S. Space Force to extend the certification of the Artemis 1 flight terminated system, which is designed to destroy the SLS if something goes wrong during launch. The Eastern Range is overseen by the Space Force.

The deadline for certification was 25 days. NASA will have to roll the Artemis 1 stack off its launch pad in Florida back to the facility's huge Vehicle Assembly Building if the Waiver isn't granted.

The weather is always a concern on the Space Coast.
