Artemis II: Destination Moon
KENNEDY SPACE CENTER, Fla. (AP) — NASA rolled back its Space Launch System rocket from Launch Pad 39B on Feb. 24, 2026, to repair a helium flow issue in the upper stage, delaying preparations for the Artemis II mission that aims to send four astronauts on a lunar flyby in April, officials said. This would mark NASA's first crewed flight to the moon since Apollo 17 in 1972.
The rollback addresses a glitch found after the rocket's initial rollout from the Vehicle Assembly Building on Jan. 17, 2026, NASA said. The crew includes commander Reid Wiseman, pilot Victor Glover, mission specialist Christina Koch and mission specialist Jeremy Hansen, the first Canadian to travel beyond low-Earth orbit to the moon. The 10-day mission will test the SLS rocket and Orion spacecraft for deep-space operations without a lunar landing.
NASA targets an April 2026 launch from Kennedy Space Center, with April 1 cited in some agency documents, sources said. The mission builds on the uncrewed Artemis I flight in 2022, which validated the hardware in deep space. Officials called the helium repair routine, expected to take up to 12 hours over a 4-mile distance using a crawler-transporter.
Hansen's role highlights international collaboration through the Canadian Space Agency, NASA and CSA officials said. He will join the U.S. astronauts in orbiting the moon, marking a milestone for Canada in the Artemis program. The CSA noted Hansen's participation as part of broader partnerships with NASA, including contributions to lunar exploration technology.
The crew features veteran NASA astronaut Wiseman as commander, Glover as pilot, Koch as mission specialist and Hansen as mission specialist, according to NASA. Backups are Andre Douglas and Jenni Gibbons. NASA selected the prime crew in 2023 for this test flight.
Artemis II aims to demonstrate life support, navigation and other systems needed for future missions, NASA said. "Artemis II builds on the success of the uncrewed Artemis I in 2022, and will demonstrate a broad range of capabilities needed on deep space missions," the agency stated on its website. Data from the flyby will inform Artemis III, targeted for a lunar landing in 2027.
Recent events included crew photos during the January rollout, part of public outreach. Boeing, a key SLS contributor, donated $190,000 for STEM education tied to a "Destination Moon" student competition, the company said. These efforts aim to inspire interest in space exploration.
Delays have plagued the Artemis program, with the rollback following inspections that revealed the helium issue. NASA held a flight readiness review in recent weeks to assess mission status, sources said. The agency says the April window remains viable after repairs.
The SLS rocket, assembled in the Vehicle Assembly Building, provides NASA's heavy-lift capability for deep-space travel. The Orion capsule will carry the astronauts on a trajectory looping around the moon before returning to Earth, with splashdown planned in the Pacific Ocean.
Artemis II revives human lunar flights after a 54-year gap since Apollo 17, crewed by Eugene Cernan, Harrison Schmitt and Ronald Evans — the last to land on the moon. Artemis seeks sustainable exploration, focusing on the lunar south pole for resources like water ice.
Broader goals include a long-term lunar presence to support Mars missions, NASA said. "The first crewed Artemis flight marks a key step toward long-term return to the Moon and future missions to Mars," the agency noted. International partners include the European Space Agency and Japan's JAXA.
Canada's involvement stems from the Artemis Accords, signed by multiple nations for cooperative exploration. Hansen, a colonel in the Royal Canadian Air Force, has trained with his NASA counterparts for over two years. His selection highlights crew diversity, with Koch set to become the first woman to fly beyond low-Earth orbit to the moon.
Public interest has surged on Florida's Space Coast, where launch schedules draw crowds. Local reports noted increased activity at Kennedy Space Center, though no delays beyond the helium repair were confirmed. NASA offers real-time tracking and mission updates on its platforms.
Unresolved details include the post-repair rollout timeline and potential launch shifts. NASA plans updates after fixes and stressed that such setbacks are common in complex missions.
Artemis II fits into a U.S. space renaissance, alongside private efforts like SpaceX's. The program includes missions through the 2030s, with projected economic benefits from lunar resources and commercial opportunities.
Crew training continues at NASA's Johnson Space Center, emphasizing emergency procedures and spacecraft operations. The astronauts have run simulations for challenges like radiation exposure and communication delays.
As repairs advance, NASA eyes the spring launch to push human spaceflight forward. Success would enable crewed landings and deeper solar system exploration.
