Artemis II: Details (step by step)

Wet Dress Rehearsal 1 (WDR1) (01-02-2026 to 03-02-2026)
01-02-2026 02:13 CET Countdown clock start (L-48 hours, 40 minutes).
03-02-2026 03:00 CET Simulated launch window opens
03-02-2026 07:00 CET Test expected to conclude
03-02-2026 T-5M15S: WDR 1 terminated (scrubbed) due to a liquid hydrogen leak at the interface of the tail service mast umbilical, which had experienced high concentrations of liquid hydrogen earlier in the countdown, as well. The launch control team is working to ensure the SLS (Space Launch System) rocket is in a safe configuration and begin draining its tanks.
03-02-2026 NASA will target March as the earliest possible launch opportunity for the flight test.
03-02-2026 Crew released from quarantine.
08-02-2026 Changes after WDR1:
- - Replaced seals at the tail service mast umbilical where higher-than-allowable liquid hydrogen concentrations were detected to fix the leak issue.
  - Drained cryogenic propellant safely from the SLS rocket and began immediate work to access and inspect the affected hardware interfaces.
  - Detached rocket and ground-side interface plates around the tail service mast to inspect and repair fueling line connections.
  - Analysis of removed seals and planning for additional testing to understand why the hardware did not seal properly.
  - Upcoming testing planned at NASA’s Stennis Space Center to evaluate repair dynamics and confirm hardware behavior before another WDR.
  - Updated test procedures for the next WDR with a focus on fueling operations.
  - Orion crew module hatch will be closed before the next rehearsal instead of during it to streamline operations.
  - Closeout crew will not deploy to the pad during the next rehearsal to prioritize fueling tests.
  - Crew access arm won’t be retracted during the next WDR, relying instead on the ground launch sequencer for that step.
  - Added extra time in planned countdown holds (two holds extended by 30 minutes each) to allow more troubleshooting without affecting overall crew timelines.
  - Launch date shifted to no earlier than March 2026 to allow time for repairs, data review, and a second WDR before confirming a launch window.
  - Astronauts continued training and mission preparedness while ground systems were addressed.

Confidence Test (12-02-2026)
12-02-2026 Operators partially filled the core stage liquid hydrogen tank to assess newly replaced seals in an area used to fill the rocket with propellant:
- - During the test, teams encountered an issue with ground support equipment that reduced the flow of liquid hydrogen into the rocket. Engineers will purge the line over the weekend to ensure proper environmental conditions and inspect the ground support equipment before replacing a filter suspected to be the cause of the reduced flow.

Wet Dress Rehearsal 2 (WDR2) (17-02-2026 to 20-02-2026)
17-02-2026 00:40 CET Launch controllers arrive at their consoles at NASA’s Kennedy Space Center to begin the nearly 50-hour countdown.20-02-2026 02:30 CET (Friday) Simulated launch time (start of the four-hour test window).
20-02-2026 02:30–06:30 CET Simulated launch window duration (4 hours).
- - 20-02-2026 Pause at T-1 minute and 30 seconds for up to three minutes, then resume until T-33 seconds before launch and pause again. After that, they will recycle the clock back to T-10 minutes and conduct a second terminal countdown to just inside of T-30 seconds before ending the sequence.
  - 20-02-2026 Engineers loaded more than 700,000 gallons of liquid propellant into the rocket, sent a closeout crew to the launch pad to demonstrate closing the Orion spacecraft’s hatches, and completed two runs of terminal count — the final phase of the launch countdown. The Artemis II crew also observed part of the test from the Launch Control Center at NASA Kennedy.
  - 20-02-2026 During the test, teams closely monitored liquid hydrogen fueling operations, which proved challenging during previous tests. Hydrogen gas concentrations remained under allowable limits, giving engineers confidence in new seals installed in an interface used to route fuel to the rocket.
  - 20-02-2026 Early in fueling operations, teams experienced a loss of ground communications in the Launch Control Center. Operators temporarily moved to backup communication methods to maintain safe propellant loading activities before normal communications channels were restored. Engineers isolated the equipment that caused the issue.
20-02-2026 Completed.
20-02-2026 While engineers review data from the test, the Artemis II crew enters quarantine late Friday, 20-02-2026 in Houston.
- - Over the next several days, technicians will use cranes to set up temporary access platforms on the mobile launcher. The platforms will allow them to reach the upper left and right segments of the SLS solid rocket boosters and core stage intertank to service the flight termination system and retest it to meet Eastern Range safety requirements. The platforms were developed based on lessons learned during Artemis I and enable NASA to complete end-to-end testing of the safety system while at the launch pad rather than rolling back to the Vehicle Assembly Building at NASA Kennedy for retesting.
  - The closeout crew also will practice closeout operations once more, adding to the team’s proficiency.
21-02-2026 NASA is taking steps to potentially rollback the Artemis II rocket and Orion spacecraft to the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida after overnight Feb. 21 observing interrupted flow of helium in the SLS (Space Launch System) rocket’s interim cryogenic propulsion stage. Helium flow is required for launch. Teams are actively reviewing data, and taking steps to enable rollback positions for NASA to address the issue as soon as possible while engineers determine the best path forward. In order to protect for troubleshooting options at both Pad B and the VAB, teams are making preparations to remove the pad access platforms installed yesterday, which have wind-driven constraints and cannot be removed during high winds, which are forecasted for tomorrow. This will almost assuredly impact the March launch window. NASA will continue to provide updates.
21-02-2026 Crew released from quarantaine.
25-02-2026 Rollback.
26-02-2026 Engineers have narrowed the issue preventing the helium flow to two potential components: a seal on the tubing’s quick disconnect and a check valve on the other end of that tubing.
08-03-2026 Florida to EDT (+1): Florida-Amsterdam +5 (UTC +1)
12-03-2026 Flight Readiness Review (FRR): Positive for launch attempt on 01-04-2026.

1. Rollout & Pad Operations (in DD-HH-MM-SS)

T-14:00:00:00 Crew in quarantaine. This period, called the health stabilization program, typically starts about 14 days before launch. Beginning quarantine now preserves flexibility as teams work toward potential opportunities in the February launch period. At this time, the agency still has not set an official launch date as testing continues for the rocket and spacecraft. Pending the outcome of the wet dress rehearsal or other operations considerations, the crew can come out of quarantine, and re-enter 14 days before any launch date.

3. Launch Day Countdown & Crew (in DD-HH-MM-SS)

T-00-00-00-29 Stop when Wet Dress Rehearsal (WDR) The first run will begin approximately 49 hours before launch when launch teams are called to their stations, to 1 minute 30 seconds before launch, followed by a planned three-minute hold and then countdown resumption to 33 seconds before launch – the point at which the rocket’s automatic launch sequencer will control the final seconds of the countdown. Teams then will recycle back to T-10 minutes and hold, then resume down to 30 seconds before launch as part of a second run.
