The Smithsonian's National Air and Space Museum holds the world's largest collection of aviation and spaceflight artefacts, from the 1903 Wright Flyer and the Spirit of St. Louis to the Bell X-1, John Glenn's Friendship 7 capsule and the Apollo 11 command module Columbia. Gyo Obata's 1976 building — four marble-clad blocks strung together by glass atria — has just emerged from a $360-million, eight-year renovation that refaced the exterior, redesigned all 20 galleries and added a new portico entrance on Jefferson Drive. Five reimagined galleries opened on 1 July 2026, the building's 50th birthday, including TEXTRON How Things Fly and the new Flight and the Arts Center. Two final galleries, At Home in Space and Modern Military Aviation, open in autumn 2026 to complete the project.
