The United States Astronaut Hall of Fame, located just south of Titusville, Florida, honors American astronauts and features the world's largest collection of their personal memorabilia, focusing on those astronauts who have been inducted into the Hall; as well as Sigma 7, the fifth manned Mercury spacecraft. Along with Sigma 7, outside of the building stands a full-scale replica of Space Shuttle Inspiration where visitors can enter the inside and view.
