Join The Museum of Flight, representatives from the local aerospace community, and fellow Seattle space fans to celebrate the live launch* of Artemis II, NASA's first crewed mission around the Moon in over 50 years. Four astronauts will venture around the Moon as the next step to establishing a long-term presence at the Moon for science and exploration through Artemis. The 10-day flight will test NASA's foundational human deep space exploration capabilities, the SLS rocket, Orion spacecraft, for the first time with astronauts.

Registration includes: 

  • Live broadcast of the Artemis II Launch 
  • An official Artemis II Mission Sticker for the first 50 attendees
  • Remarks from the local space community

FAQs

Is a live launch guaranteed? 
No. Launch decisions are at the sole discretion of NASA and will not be made for an attempt to launch until system checks are complete. As teams evaluate the rocket, spacecraft, ground systems, and crew, they will gain the information necessary to formalize a date in the available windows. Launch opportunities also depend on orbital mechanics; the Moon must be in just the right position for the mission’s planned trajectory. 

What happens if the launch is postponed?
If NASA and Artemis Flight Operations scrub the launch for the designated date and time, a launch attempt will be made the following evening according to the launch windows determined by NASA.

What happens to my RSVP if the launch is postponed?
Registrations will automatically roll over to the next launch window’s date and time. Please watch your email for any correspondence from marketing@museumofflight.org. 

Is this event family-friendly?
Yes, this event is for space fans of all ages. 

Will I receive updates if plans change?
Yes, those who have registered will receive updates via email and on-site announcements when information becomes available. 

Will the Museum’s galleries be open during the launch party?
The Watch Party is free to attend, though pre-registration is requested. If the Watch Party occurs during the Museum's public hours, paid admission will be required to tour the galleries. Because the event is subject to change, the location of where the Watch Party takes place inside the Museum may also change. We will share if exploration of exhibits will be available if the event occurs after public hours in the Know Before You Go email and at check-in.

Will there be astronauts present at the Watch Party?
As with the launch timing, details are subject to change. We are finalizing the guest list of aerospace representatives and will update this page as participants are confirmed.
