America's first manned space program was best summed up by Deputy Administrator, Hugh L. Dryden in the foreword to the book, Project Mercury: A Chronology (NASA SP-4001) where he wrote “ Project Mercury is now history In its short span of four years, eight months, and one week as the Nation's first manned space flight program, Mercury earned a unique place in the annals of science and technology. The culmination of decades of investigation and application of aerodynamics, rocket propulsion, celestial mechanics, aerospace medicine, and electronics, Project Mercury took man beyond the atmosphere into space orbit and confirmed the potential for man's mobility in his universe. It remains for Projects Gemini and Apollo to demonstrate that potential.” There are many fine books on Project Mercury, you can use your computer's search function to find them or go to your local library.
