Nasa plans to launch its Artemis II mission in early April. This mission will send astronauts around the Moon for the first time in over 50 years.
The rocket was initially set for a March launch. However, a helium leak was found, requiring the rocket to return to the Vehicle Assembly Building in Cape Canaveral, Florida, for repairs.
Mission Preparations and Risks
Nasa is confident the leak is fixed. They plan to move the rocket back to the launchpad on March 19. The earliest possible launch date is April 1.

Nasa leaders have stressed the risks involved with this mission. John Honeycutt, chair of the Artemis II Mission Management Team, explained they are assessing all possible issues. He noted that historically, new rockets have a 50% success rate. However, he believes Nasa is in a much better position due to their focus on understanding and reducing risks.
The Artemis II crew includes three US astronauts: Reid Wiseman, Victor Glover, and Christina Koch. Canadian astronaut Jeremy Hansen will also join them. They will be the first humans to fly on Nasa's Space Launch System rocket and in the Orion spacecraft.
The mission will last 10 days. The crew will travel around the far side of the Moon, which is never visible from Earth, before returning home.
Looking Ahead to Launch
The Nasa team will not conduct another "wet dress rehearsal" once the rocket is on the launchpad. This test involves fueling the rocket and running through the countdown. Lori Glaze, acting associate administrator for Exploration Systems Development Mission Directorate, stated that little more would be gained from it. The next time the vehicle is fueled will be for the actual launch attempt.
Glaze added that there is still work to be done before a launch date is confirmed. She said Nasa is comfortable targeting April 1 as the first opportunity. However, she emphasized they will launch only when the hardware is ready.
Nasa is under pressure to launch Artemis II. The mission has already been delayed by two years. This was due to issues found with the heat shield on the first Artemis mission, which flew without a crew. In December 2024, Nasa set a deadline to launch Artemis II before the end of April 2026. Glaze confirmed they are currently very focused on the April target.
