Air & Space/Smithsonian magazine is a bimonthly magazine put out by the National Air and Space Museum. Because the museum is a part of the Smithsonian Institution, which puts out its own Smithsonian magazine, the magazine's full title is Air & Space/Smithsonian. Therefore, the word "Smithsonian" appears on the cover, just beneath "AIR&SPACE", in a much smaller size. Articles in the magazine involve topics related to aviation, space travel, and space-related physics.
