WASHINGTON, DC.- The Smithsonian’s National Air and Space Museum has announced the next phase of gallery openings at its flagship building in Washington, D.C. Five new exhibitions, the Lockheed Martin IMAX Theater and the museum’s redesigned entrance on Jefferson Drive along the National Mall will open Monday, July 28. The project to renovate the entire museum began in 2018 and will culminate next year when the remaining galleries open July 1, 2026, the 50th anniversary of the museum in Washington and in time for the United States’ 250th anniversary.

Thousands of artifacts will go back on display in the reopened galleries. Favorites such as the Spirit of St. Louis, the North American X-15, John Glenn’s Mercury Friendship 7 capsule, Apollo Lunar Module 2 and the touchable moon rock will be back on view. Several artifacts new to the building in Washington will include the Sopwith F.1 Camel, Virgin Galactic’s RocketMotorTwo, a Blue Origin New Shepard crew capsule mockup and a Goddard 1935 A series rocket.

Free timed-entry passes will still be required to visit the museum. Passes for the July 28 opening and beyond will be available on the museum’s website starting June 13.
