Project Mercury was the first
human spaceflight program of the
United States, running from 1958 through 1963. An early highlight of the
Space Race, its goal was to put a human into Earth
orbit and return the person safely, ideally before the
Soviet Union. Taken over from the
U.S. Air Force by the newly created civilian space agency
NASA, it spanned twenty unmanned developmental missions involving test animals, and successful missions completed by six of
the seven selected Mercury astronauts.
The Space Race had begun with the 1957 launch of the Soviet satellite Sputnik 1. This came as a shock to the American public, and led to the creation of NASA to expedite existing U.S. space exploration efforts, and place most of them under civilian control. After the successful launch of the Explorer 1 satellite in 1958, manned spaceflight became the next goal.
The program took its name from the wing-footed, fleet god of travel in Roman mythology, and is estimated to have cost $2.24 billion (current prices) and to have involved the work of 2 million people. The astronauts were collectively known as the "Mercury Seven", and each spacecraft was given a name ending with a "7" by its pilot.
After a slow start riddled with humiliating mistakes, the Mercury Project gained popularity, its missions followed by millions on radio and TV around the world. Its success laid the groundwork for Project Gemini, which carried two astronauts in each capsule and perfected space docking maneuvers essential for lunar travel, and the subsequent Apollo Moon-landing program announced a few weeks after the first manned Mercury flight. However, they were unable to beat the Soviet space program to the goal of the first man in space, and emerged from the program still behind the Soviet Union.
Joseph Francis Shea (September 5, 1925 – February 14, 1999) was an
American aerospace engineer and
NASA manager. Born in the
New York City borough of
the Bronx, he was educated at the
University of Michigan, receiving a
Ph.D. in
Engineering Mechanics in 1955. After working for
Bell Labs on the radio
inertial guidance system of the
Titan I intercontinental ballistic missile, he was hired by NASA in 1961. As Deputy Director of NASA's Office of Manned Space Flight, and later as head of the Apollo Spacecraft Program Office, Shea played a key role in shaping the course of the
Apollo program, helping to lead NASA to the decision in favor of
lunar orbit rendezvous and supporting "all up" testing of the
Saturn V rocket. While sometimes causing controversy within the agency, Shea was remembered by his former colleague
George Mueller as "one of the greatest
systems engineers of our time".
Deeply involved in the investigation of the 1967 Apollo 1 fire, Shea suffered a nervous breakdown as a result of the stress that he suffered. He was removed from his position and left NASA shortly afterwards. From 1968 until 1990 he worked as a senior manager at Raytheon in Lexington, Massachusetts, and thereafter became an adjunct professor of aeronautics and astronautics at MIT. While Shea served as a consultant for NASA on the redesign of the International Space Station in 1993, he was forced to resign from the position due to health issues.
