On April 21, 1962 the Century 21 Exposition opened its gates in Seattle. The six-month Expo attracted some 10 million visitors and left an indelible vision of what the future would be like for a generation coming of age in the Space Age.
The Expo was developed during the early efforts to get humans into space. It featured the first pavilion ever by NASA, the United States’ space agency. It was funded in part by federal spending spurred by the Soviet’s launch of the satellite Sputnik. And it was built during the first successful manned space flights. John Glenn’s Friendship 7 space capsule, in which the astronaut orbited the earth, was exhibited at the Expo, which was also visited by astronauts and cosmonauts.
