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.
Sergey Pavlovich Korolyov (December 30, 1906 - January 14, 1966) was a Soviet rocket engineer and is widely regarded as the founder of the Soviet space program. In July 1932, Korolev was appointed chief of Jet Propulsion Research Group, GIRD, one of the earliest state-sponsored centers for rocket development in the USSR. In 1933, the group was reorganized into the Jet Propulsion Research Institute, RNII, where Korolyov worked as Deputy Chief of the institute. At RNII, Korolyov led the development of cruise missiles and of a manned rocket-powered glider. He also participated in the development of the Tu-2 bomber, a major aircraft of the Soviet Air Force during World War II. In 1945, he was commissioned into the Red Army, with a rank of colonel and, along with other rocket experts, he was flown to Germany to gather information on the German V-2 rocket. Korolyov worked on the R-1 missile which was a replica of the German V-2 ballistic missile. In 1947 the NII-88 group under Korolyov began working on more advanced designs, with improvements in range and throw weight. This led to the R-2 and R-3 ballistic missiles and finally the R-7 ICBM. He successfully convinced the Soviet leaders to fund the Sputnik program. The actual development of Sputnik was performed in less than a month. Finally on 4 October 1957, launched on a rocket that had only successfully launched once, the satellite was placed in orbit. This was followed by the launch of Sputnik 2 and 3. Korolyov's planning for a manned mission had begun back in 1958, when design studies were made on the future Vostok spacecraft. After the success of Vostok, Korolyov planned to move forward with Soyuz spacecraft that would be able to dock with other craft in orbit and exchange crews. For the moon race, Korolyov's staff designed the immense N1 rocket. He also had in work the design for the Soyuz manned spacecraft, as well as the Luna vehicles that would soft land on the Moon and unmanned missions to Mars and Venus. But, unexpectedly, he was to die before he could see his various plans brought to fruition. (Full article...)
