NASA is preparing to launch its Artemis II mission in early April, marking the first crewed flight around the Moon in more than five decades. The launch was initially scheduled for March but was delayed due to a helium leak, which prompted the rocket to be returned to the Vehicle Assembly Building for repairs.
NASA confirmed that the issue has been resolved. The rocket is set to return to the launchpad on 19 March, with the earliest possible launch date of 1 April.
Artemis II Crew and Mission Details
The mission will carry four astronauts:
-
Reid Wiseman
-
Victor Glover
-
Christina Koch
-
Jeremy Hansen
They will be the first humans to fly on NASA’s Space Launch System (SLS) and aboard the Orion spacecraft. During the 10-day mission, the crew will travel around the far side of the Moon and return safely to Earth.
Mission Safety and Risks
John Honeycutt, chair of the Artemis II Mission Management Team, highlighted the mission’s risks. He said NASA carefully evaluates every potential issue to maximize success.
“Over the history of building new rockets, success rates start around 50%, but we are in a much stronger position now,” he said. “We mitigate risk and implement controls to manage challenges effectively.”
NASA officials confirmed they will not perform another wet dress rehearsal, a pre-launch test where the rocket is fueled and countdown procedures are simulated. The next fueling will occur during the actual launch attempt.
Launch Timeline and Delays
Acting Associate Administrator Lori Glaze said NASA is aiming for April 1 as the first possible launch opportunity, but final preparations at the assembly building and launchpad are still ongoing. The team will proceed only when the hardware is fully ready.
The Artemis II mission has faced multiple delays, including a two-year postponement after heat shield issues on the first Artemis mission. That flight tested the Space Launch System and Orion capsule without a crew.
NASA remains focused on launching Artemis II in April 2026, as previously committed.
