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.
Sally Ride (May 26, 1951 – July 23, 2012) was an American
physicist and
astronaut.
Born in Los Angeles, she joined NASA in 1978 and became the first American woman in space in 1983. She remains the youngest American astronaut to have traveled to space, having done so at the age of 32. After flying twice on the Orbiter Challenger, she left NASA in 1987. She worked for two years at Stanford University's Center for International Security and Arms Control, then at the University of California, San Diego as a professor of physics, primarily researching nonlinear optics and Thomson scattering.
She served on the committees that investigated the Challenger and Columbia Space Shuttle disasters, the only person to participate on both.
Ride died following a 17-month-long battle with pancreatic cancer on July 23, 2012. Shortly before her death, she came out as a homosexual in a statement through her philanthropic enterprise, Sally Ride Science.
