NASA is set to move its Artemis 2 moon rocket to the launch pad next week, aiming for a possible liftoff on April 1, 2026. This mission will send four astronauts on a nine-day journey around the moon. Following a flight readiness review, NASA officials confirmed that all teams are prepared for the launch, pending the completion of final preparations.
Lori Glaze, associate administrator of Exploration Systems Development at NASA, stated, “All the teams polled ‘go’ to launch and fly Artemis 2 around the moon, pending completion of some of the work before we roll out to the launch pad.” She emphasized that while the mission is a test flight fraught with risks, the team and equipment are ready for the challenge.
Timing for the launch is critical. Based on the complex dynamics of the positions of the moon and Earth, NASA must launch Artemis 2 by April 6 to avoid further delays. A liftoff on April 1 is targeted for 18:24 EDT, with a planned splashdown in the Pacific Ocean nine days later.
Originally, NASA planned to launch the mission in early February, but the schedule was pushed back due to hydrogen fuel leaks and issues with the rocket’s upper stage propellant pressurization system. To address the hydrogen leaks, technicians replaced seals in the umbilical system connecting the rocket to its fuel lines. However, engineers were unable to access the upper stage at the launch site, necessitating a return to the Vehicle Assembly Building.
Inside the assembly facility, engineers quickly identified and replaced a displaced seal in a helium quick-disconnect fitting, resolving the pressurization issue. Additional work included replacing batteries in the rocket’s self-destruct system and charging batteries in the Orion capsule’s launch abort system. NASA managers confirmed that these tasks are nearing completion, allowing for the rocket’s rollout to launch pad 39B next Thursday evening.
Shawn Quinn, manager of Artemis ground systems, expressed pride in the team’s efficient resolution of the helium pressurization problem. “So far, the VAB processing has gone very well,” he noted.
During the flight readiness review, discussions about mission risk were prevalent. Although Glaze and John Honeycutt, chairman of NASA’s Artemis mission management team, refrained from disclosing specific risk figures, they acknowledged the inherent challenges. A report from NASA’s Office of Inspector General previously suggested that the risk threshold for an Artemis moon mission, based on the use of a SpaceX lander, was around 1-in-40 during lunar operations, with overall mission risk estimated at 1-in-30 from launch to splashdown.
Artemis 2 will not involve a lunar landing, but it represents the first piloted flight of the Space Launch System (SLS) rocket and the Orion capsule following an uncrewed test flight in 2022. Given the limited flight history and the long intervals between launches, Glaze and Honeycutt pointed out the difficulty in establishing a reliable risk assessment.
NASA’s Artemis program, initiated during the first Trump administration, aims to return astronauts to the lunar surface. Originally scheduled for 2024, the timeline has faced multiple delays due to budget constraints, the COVID-19 pandemic, and various technical challenges, pushing the first moon landing back to 2028.
The Artemis 2 mission will be followed by Artemis 3 in the next year, which will involve astronauts aboard an Orion capsule docking with lunar landers developed by SpaceX and Blue Origin. This step will allow NASA to test spacecraft and procedures in preparation for actual landings.
Assuming the mission proceeds as planned, Artemis 2’s crew will fly within approximately 4,100 miles of the moon’s surface. This journey will take them farther from Earth—around 252,800 miles—than any humans have traveled before. The crew, including commander Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen, will spend the initial day of their mission checking the Orion’s flight control, communications, navigation, and life support systems in both low and high Earth orbit before making their approach to the moon.
As the countdown to April 1 continues, NASA remains focused on ensuring a successful mission, marking another significant step in its ambitious Artemis program.
