Artemis II Launch Now Expected April 1st

NASA announced on March 12th the successful completion of the Flight Readiness Review (FRR) for Artemis II. This final verification process certified the readiness of the mission's systems and teams, with all lead personnel giving their "go." The Space Launch System (SLS) rocket will now be returned to the Kennedy Space Center launch pad for final preparations.

The rollout to Launch Complex 39B is scheduled for March 19th. The first launch opportunity is set for April 1st in Florida. The launch window will open at 22:22 UTC on April 1st, which will be 00:22 AM on April 2nd in Italy.

Crew Preparations

The mission's crew virtually participated in the FRR. NASA confirmed the astronauts are flight-ready, and their quarantine will commence on March 18th, exactly 14 days before launch. They will transfer to Kennedy Space Center on March 27th for final preparations before boarding Orion and SLS on April 1st.

Furthermore, NASA stated that a new Wet Dress Rehearsal (WDR) with the rocket on the pad is not planned. The vehicle will be fueled with propellants directly during the launch attempt.

During the review, a technical issue concerning the helium flow system was addressed. Engineers removed and analyzed a suspected component, revealing that a seal had obstructed the passage of helium through a quick disconnect. The problem was successfully replicated and precisely identified.

The component was modified by removing the problematic seal and reinforcing another, designed to be less prone to displacement or detachment. Program officials deem the adopted solution adequate and do not foresee the need to replace other seals in the hydrogen fueling system once the rocket is back on the pad.

Artemis II will be the first crewed mission of the Artemis program and marks humanity's return to cislunar space exploration after over fifty years since the Apollo missions. The Orion capsule will carry four astronauts into an orbit around the Moon, without landing, with the objective of testing the complete system under operational conditions before future crewed lunar missions.
