Artemis II moon flight delayed to March, Canada’s Jeremy Hansen on the crew
NASA has postponed the Artemis II crewed lunar flyby by at least a month after a fuelling rehearsal. The earliest new launch date is March 6; crew travel plans are on hold.

NASA has pushed back the Artemis II launch, moving the earliest possible liftoff from February to March. The change follows a day-long fuelling exercise, and the agency said it needs more time to review data and run a second dress rehearsal.
The crew for Artemis II includes Canadian Space Agency astronaut Jeremy Hansen. The mission will send four astronauts on a crewed flyby around the moon, the first such crewed mission in NASA’s Artemis programme.
Why NASA delayed the launch
NASA conducted a full fuelling rehearsal in February at Kennedy Space Center in Florida. After reviewing telemetry and procedure data from that exercise, the agency concluded that teams require additional time to assess results and carry out another dress rehearsal before committing to a launch date.

The delay affects the original February launch window. NASA now lists March 6 as the earliest possible launch date, though that date could shift again depending on the findings from the extra rehearsal and subsequent checks.
What this means for the crew and schedule
Crew members had been scheduled to travel to Kennedy Space Center this week. That movement has been postponed, and NASA released the astronauts from pre-flight quarantine in Houston. Ground teams will use the additional time to analyse rehearsal data and address any between-system issues identified during the fuelling operations.
Delays are not unusual on complex human spaceflight missions. Systems checks, propellant handling, and integrated dress rehearsals are designed to surface issues on the ground rather than during a launch attempt.
Artemis II: what the mission will do
Artemis II is planned as a crewed lunar flyby, carrying four astronauts around the moon and back to Earth. The mission will test Orion spacecraft systems with humans aboard, including life-support, navigation, and communications, ahead of later missions intended to return humans to the lunar surface.
Canada’s involvement includes astronaut Jeremy Hansen, who brings experience from previous astronaut training and missions. The flight represents a milestone in international partnership within the Artemis programme.
Key dates and next steps
- Original earliest launch window: February 8
- New earliest possible launch date: March 6
- Immediate next step: second dress rehearsal and further data review
- Crew movement: postponed, astronauts released from Houston quarantine
NASA and partner agencies will provide updates as teams complete the additional rehearsal and verify any corrective actions. Mission controls will only set a firm launch date once the agency is satisfied with all checkouts and safety margins.
What to watch for
Watch for official status updates from NASA and the Canadian Space Agency. Those updates will announce a firm launch date, the outcome of the second dress rehearsal, and any adjustments to crew schedules. Media briefings typically follow major milestone checks.
Observers and supporters in Canada can expect further announcements about Hansen’s public engagements and any mission-related outreach once the launch timeline is finalised.
The Artemis II delay is a reminder of the complexity of crewed spaceflight. Teams are prioritising additional testing now to reduce the risk of problems during launch and transit, keeping the focus on safety as the programme prepares for its next major milestone.
