Artemis II will be launching from Florida on April 1st at 22:24 UTC. Watch on NASA's broadcast

The Artemis II astronauts, now suited up for launch, are headed to the launch pad.

The crew includes NASA astronauts Astro Reid, Victor Glover, and Christina H Koch, and CSA ASC astronaut Jeremy R. Hansen.

The Artemis II crew is boarding Orion. 

Reid, Victor, Christina, and Jeremy are taking their seats atop the most powerful manned rocket ever built. They have trained for years for this moment, and now they are preparing to execute a mission that will take us back around the Moon and begin the next chapter of human space exploration.

The hatch is now closed.

The Artemis II astronauts are now strapped into their seats and ready for launch.

Science is a key part of Artemis II

Watch as NASAScience’s Dr. Nicky Fox, breaks down the science of this historic mission that will pave the way for future human exploration of the Moon, Mars, & beyond.

Teams are troubleshooting an issue with a LAS (launch abort system) battery on the vehicle being outside the acceptable range. If unresolved, this could trigger an abort criteria closer to launch. The range remains green and the timeline is progressing towards Artemis 2.

Europe keeps a close eye on the countdown to the Artemis II launch too.

At European Space Agency's facilities in the Netherlands, teams from the European Service Module are already on console for the 10-day mission.

All systems are GO from the Eagle room, Europe’s mission evaluation hub.

Artemis II update from NASA summarised:
• Vehicle successfully configured for flight
• Issue with battery won't affect launch
• Weather is 90% go for launch

NASA has not set a new T-0 but the Artemis II mission will not launch at 6:24 pm ET today. “A little more work” to do.
