No foolin’! The Artemis 2 mission is back on track for launch!
With repairs to the Orion spacecraft and Space Launch System rocket now completed, NASA has officially set April 1, 2026, as the next opportunity to launch the Artemis 2 mission to the Moon.
Two weeks ago, on February 25, ground crews at Kennedy Space Center in Florida rolled Orion and SLS away from Launch Complex 39B, returning them to the Vehicle Assembly Building to address issues with the rocket’s fuel system that were discovered shortly after the Wet Dress Rehearsal on Feb. 19.

Although the run-through of the prelaunch sequence was deamed a success, the next night, crews noted interruptions in the flow of liquid helium through the SLS upper stage fuel system. Since the helium is critical for keeping the rocket’s oxygen and hydrogen fuels in liquid form, this issue was considered serious enough to call off any planned launch attempts in March. The rocket was then rolled back to the VAB to give the ground crew full access to all of its systems, to assess and address the problem.
“Engineers determined a seal in the quick disconnect, through which helium flows from the ground systems to the rocket, was obstructing the pathway,” the agency reported in a March 3 mission update. The seal has now been repaired, and ground crews took the opportunity to perform maintanence on the rocket, including replacing a seal on the liquid oxygen line feed system.
NASA is now preparing to roll Orion and the SLS back to Launch Complex 39B. Subject to changes in the weather, the next opportunity for the rollout will be on March 19. If that goes as planned, it opens up the first launch window for Artemis 2 on April 1, 2026.

During a briefing on March 12, NASA officials also announced the addition of one more day to the potential launch windows. Previously, the available dates in April were the 1st, 3rd, 4th, 5th, 6th, and 30th. Now, they have added a window for April 2, which opens at 7:22 p.m. EDT.
