NASA's Project Mercury had three simple goals. First was to orbit a crewed spacecraft about the Earth, second was to test human ability to function in space, and third was the successful re-entry and recovery of the crewed orbital spacecraft. Initial tests of Project Mercury were uncrewed and in some cases carried primates to test the effects of weightlessness prior to crewed spaceflight missions. Project Mercury was highly successful with six crewed flights in a two year period (1961-1963).
The first crewed Mercury flight (5 May 1961) launched the Freedom 7 spacecraft, piloted by Alan Shepard, on a suborbital test flight. Shepard landed safely in the Atlantic Ocean, giving the United States its critical first human spaceflight experience. The flight, though short, was a huge relief. At the time the Soviet Union had orbited a cosmonaut (12 April 1961), Yuri Gagarin, about the Earth while the United States was having problems getting rockets off the pad without an explosion. The American public was deeply concerned that the United States had indeed fallen behind the Soviet Union in the realm of rocketry, and technology development in general. Today it is hard for most people to comprehend the mighty decades-long struggle between the Western Allies and the Warsaw Pact, but space exploration was one of the most important fronts in the Cold War. Shepard's short flight was perceived as a tentative affirmation of the American way of life. It was not until nine months later (2 February 1962) that John Glenn orbited the Earth in his Mercury spacecraft Friendship 7, but America was still lagging behind the Soviet Union.
Less than three weeks after Shepard's flight (25 May 1961) President Kennedy challenged America "to send a man to the Moon and return him safely to Earth" by the end of the decade. With only fifteen minutes of human spaceflight experience to build upon, sending a human to the Moon in this short time frame was an audacious goal. Project Mercury was followed by the successful Project Gemini and then, of course, the Apollo Program, which fulfilled Kennedy's challenge. Today the other crewed and uncrewed Mercury flights are mostly forgotten. However each flight played a critical role in NASA's early efforts to learn to fly in space. These high resolution scans of the original Mercury flight films bring these historic flights to life.
