This is pretty fun. This was sort of an early find your own adventure book. You would spin the dial and follow the story of a visit to Cape Kennedy, learning all about space flight. The story follows a boy exploring various aspects of astronaut training and the space program. After reading each section you spin to find out which of 5 possible sections you go to next.
Sorry there are not more scans, one of those books I need to dig out of the archives and re-scan.
