Rollout Set for March 19

Today I was in the press room at the Kennedy Space Center for NASA’s briefing following completion of the Artemis II Flight Readiness Review (FRR). The review represents one of the final major milestones before launch, bringing together engineering teams, mission managers, and flight operations leaders to determine whether the Space Launch System rocket, Orion spacecraft, and supporting ground systems are ready for flight.

The briefing featured (left to right in photo above) Lori Glaze, Acting Associate Administrator for NASA’s Exploration Systems Development Mission Directorate; John Honeycutt, Chair of the Artemis II Mission Management Team; Shawn Quinn, Manager of the Exploration Ground Systems Program; and Norm Knight, Director of NASA’s Flight Operations Directorate.

The key announcement from the briefing was that rollout of the Artemis II vehicle is scheduled for March 19, with the first launch opportunity targeted for April 1 at 6:24 p.m. Eastern.

NASA officials also noted that April 2 is another available launch opportunity, with additional possible launch dates including April 3 through April 6 and April 30, depending on trajectory requirements and mission constraints.

A Thorough Flight Readiness Review

Glaze described the FRR as an extensive evaluation of every aspect of mission preparedness. The discussions focused heavily on the mission’s overall risk posture and the efforts undertaken to mitigate potential risks.

According to Glaze, the discussions were complete and intense, with open and honest feedback from the teams responsible for the mission. The Artemis II astronauts also participated in the review virtually. At the conclusion of the process, each team was formally polled for readiness.

All reported “go” for flight.

Glaze emphasized, however, that the work continues. Thousands of people across NASA and its industry partners remain engaged in preparing the rocket, spacecraft, and ground infrastructure for launch.

When asked about possible launch dates in May, she acknowledged that additional windows exist later in the calendar but stressed that the team’s focus right now is on the April opportunities.

Resolving the Helium Flow Issue

A major topic during the briefing was the helium flow issue that prompted NASA to roll the rocket back to the Vehicle Assembly Building (VAB) earlier in the campaign. Shawn Quinn explained that the problem originated in a Quick Disconnect (QD) connection between the upper stage and the ground umbilical system.

Engineers removed the QD assembly and constructed a test configuration to simulate the connection. Through extensive testing, they determined that a seal could become dislodged under high pressure and block the helium flow.

To resolve the issue, the problematic seal was removed, and engineers redesigned another seal in the system to take over the required function. After numerous tests, the configuration was flight certified and reinstalled in the Artemis II upper stage.

While the vehicle was inside the VAB, teams also took the opportunity to complete additional work, including replacing the flight termination system batteries, charging them, and conducting further testing of the system.

Preparing for Launch Day

NASA teams also continued refining launch operations.

Quinn noted that the Crew Closeout Team, responsible for assisting astronauts as they board Orion on launch day, recently completed a full two-hour and forty-minute rehearsal and is ready for flight day operations.

Norm Knight provided an update on the readiness of the astronauts and the flight operations team.

“The astronauts are 100 percent ready,” Knight said, noting that they have full confidence in the rocket, spacecraft, and the integrated operations team supporting the mission.

The Flight Operations Directorate has completed more than 130 mission simulations, rehearsing both nominal operations and contingency scenarios.

Knight also noted that while NASA now has more than 25 years of human spaceflight experience in low Earth orbit with the ISS, missions to the Moon represent a very different operational challenge. Low Earth orbit operations, he said, do not fully prepare you for going to the Moon. That reality is why the Artemis II team has spent years preparing for this mission through simulations, testing, and careful review.

A Measured Confidence

John Honeycutt reflected on the philosophy guiding the review process, referencing what he called the danger of a “failure of imagination.” The mission team has worked to carefully examine potential risks and ensure they are mitigated wherever possible.

Despite the positive outcome of the Flight Readiness Review, Honeycutt emphasized that the team remains focused and cautious.

“A clean FRR is not the time to celebrate,” he said. “That will be when the astronauts are home safely.”

Key Milestones Ahead

If the schedule holds, several milestones will occur in the coming weeks:

• March 18 (L-14): Astronaut quarantine begins
• March 19 (L-13): Rollout to Launch Complex 39B
• March 27 (L-5): Crew arrival at Kennedy Space Center
• April 1: First launch opportunity – 6:24 p.m. ET

NASA officials also confirmed that no additional wet dress rehearsal is planned before launch.

With the Flight Readiness Review complete and hardware work progressing, Artemis II now enters the final phase of preparations for humanity’s first crewed mission beyond low Earth orbit in more than half a century.

From what we heard in yesterday’s briefing, the mission is in excellent shape and moving steadily toward launch.
