KENNEDY SPACE CENTER, FL — March 13, 2026 — NASA has officially greenlit the first crewed mission to the Moon in over 50 years. Following a high-stakes Flight Readiness Review (FRR) held yesterday, March 12, agency leaders announced that all systems are “go” for an April 1 launch of the Artemis II mission.
The decision marks a major victory for the agency after a month of technical setbacks that threatened to push the historic flight further into 2026. The mission will send four astronauts—Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen—on a 10-day journey around the lunar far side.
Solving the Helium Crisis
The path to this “go” decision was not easy. In late February, following a successful “wet dress rehearsal,” engineers detected an interruption in the flow of helium to the Space Launch System (SLS) rocket’s upper stage. Helium is vital for maintaining pressure in the fuel tanks as propellant is consumed.
The issue forced a dramatic “rollback” of the 322-foot-tall rocket from the launch pad to the Vehicle Assembly Building (VAB).
-
The Culprit: Technicians traced the fault to a dislodged seal within a “Quick Disconnect” (QD) connection.
-
The Fix: Over the last week, teams removed the QD assembly, reseated the seal, and redesigned an auxiliary seal to ensure it remains stationary under the high pressures required for liftoff.
-
Secondary Work: While inside the VAB, NASA also replaced the batteries for the Flight Termination System (FTS), ensuring the rocket can be safely destroyed if it veers off course during launch.
The Road to Liftoff
With the repairs complete and certified, the countdown to launch has effectively begun.
-
March 18: The crew enters official pre-flight medical quarantine at Johnson Space Center.
-
March 19: The SLS rocket and Orion spacecraft will begin their slow, four-mile journey back to Launch Pad 39B atop the crawler-transporter.
-
March 27: The four-person crew will fly to the Kennedy Space Center for final preparations.
-
April 1 (6:24 PM EDT): The primary launch window opens. If delayed, backup windows are available between April 2 and April 6.
Mission Profile: Beyond Apollo
While the Apollo missions landed on the lunar surface, Artemis II is a “free-return” test flight designed to verify the Orion spacecraft’s life-support systems for humans. The crew will travel roughly 10,300 km (6,400 miles) beyond the far side of the Moon, venturing further into deep space than any human in history.
“We had extremely thorough discussions. We talked a lot about our risk posture and how we’re mitigating those risks,” said Lori Glaze, NASA’s acting associate administrator. “It’s a test flight, and it is not without risk, but our team and our hardware are ready.”
