What was the name of NASA's geodesic-dome science exhibit for the 1976 U.S. Bicentennial?

NASA's geodesic-dome science and technology exhibit for the 1976 U.S. Bicentennial was called Third Century America.

NASA installed the exhibit in a series of geodesic domes in the parking area of the Vehicle Assembly Building at Kennedy Space Center. The presentation looked toward the nation's technological future as the United States commemorated two centuries of history.

The exhibit formed part of NASA's broader Bicentennial activities. The agency also placed an American flag and the Bicentennial emblem on the Vehicle Assembly Building, one of the most recognizable structures at the space center.

NASA originally planned for Viking 1 to land on Mars on July 4, 1976, which would have made the mission a spectacular anniversary event. The landing was delayed until July 20, the anniversary of Apollo 11's lunar landing. The name Third Century America reflected the transition from celebrating the past to imagining the nation's next century.
