The Apollo program, also known as Project Apollo, was the United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which succeeded in preparing and landing the first men on the Moon in 1969. It was first conceived in 1960 during President Dwight D. Eisenhower's administration as a three-person spacecraft to follow the one-person Project Mercury, which put the first Americans in space. Apollo was later dedicated to President John F. Kennedy's national goal for the 1960s of "landing a man on the Moon and returning him safely to the Earth" in an address to Congress on May 25, 1961. It was the third US human spaceflight program to fly, preceded by the two-person Project Gemini conceived in 1961 to extend spaceflight capability in support of Apollo.
Human spaceflight is spaceflight with a crew or passengers aboard a spacecraft, often with the spacecraft being operated directly by the onboard human crew. Spacecraft can also be remotely operated from ground stations on Earth, or autonomously, without any direct human involvement. People trained for spaceflight are called astronauts, cosmonauts (Russian), or taikonauts (Chinese); and non-professionals are referred to as spaceflight participants or spacefarers.
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 man into Earth orbit and return him safely, ideally before the Soviet Union. Taken over from the US Air Force by the newly created civilian space agency NASA, it conducted 20 uncrewed developmental flights, and six successful flights by astronauts. The program, which took its name from Roman mythology, cost $2.68 billion. The astronauts were collectively known as the "Mercury Seven", and each spacecraft was given a name ending with a "7" by its pilot.
Virgil Ivan "Gus" Grissom was an American engineer and pilot in the United States Air Force, as well as one of the original men, the Mercury Seven, selected by the National Aeronautics and Space Administration for Project Mercury, a program to train and launch astronauts into outer space. Grissom was also a Project Gemini and Apollo program astronaut for NASA. As a member of the NASA Astronaut Corps, Grissom was the second American to fly in space in 1961. He was also the second American to fly in space twice, preceded only by Joe Walker with his sub-orbital X-15 flights.
John Herschel Glenn Jr. was an American Marine Corps aviator, astronaut, businessman, and politician. He was the third American in space and the first American to orbit the Earth, circling it three times in 1962. Following his retirement from NASA, he served from 1974 to 1999 as a U.S. Senator from Ohio; in 1998, he flew into space again at the age of 77.
Alan Bartlett Shepard Jr. was an American astronaut. In 1961, he became the second person and the first American to travel into space and, in 1971, he became the fifth and oldest person to walk on the Moon, at age 47.
The Space Race was a 20th-century competition between two Cold War rivals, the United States and the Soviet Union, to achieve superior spaceflight capability. It had its origins in the ballistic missile-based nuclear arms race between the two nations following World War II and had its peak with the more particular Moon Race to land on the Moon between the US moonshot and Soviet moonshot programs. The technological advantage demonstrated by spaceflight achievement was seen as necessary for national security and became part of the symbolism and ideology of the time. The Space Race brought pioneering launches of artificial satellites, robotic space probes to the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and ultimately to the Moon.
The Lyndon B. Johnson Space Center (JSC) is NASA's center for human spaceflight in Houston, Texas, where human spaceflight training, research, and flight control are conducted. It was renamed in honor of the late U.S. president and Texas native, Lyndon B. Johnson, by an act of the United States Senate on February 19, 1973.
Mercury-Redstone 3, or Freedom 7, was the first United States human spaceflight, on May 5, 1961, piloted by astronaut Alan Shepard. It was the first crewed flight of Project Mercury. The project had the ultimate objective of putting an astronaut into orbit around the Earth and returning him safely. Shepard's mission was a 15-minute suborbital flight with the primary objective of demonstrating his ability to withstand the high g-forces of launch and atmospheric re-entry.
Walter Marty Schirra Jr. was an American naval aviator, test pilot, and NASA astronaut. In 1959, he became one of the original seven astronauts chosen for Project Mercury, which was the United States' first effort to put humans into space. On October 3, 1962, he flew the six-orbit, nine-hour, Mercury-Atlas 8 mission, in a spacecraft he nicknamed Sigma 7, becoming the fifth American and ninth human to travel into space. In December 1965, as part of the two-man Gemini program, he achieved the first space rendezvous, station-keeping his Gemini 6A spacecraft within 1 foot (30 cm) of the sister Gemini 7 spacecraft. In October 1968, he commanded Apollo 7, an 11-day low Earth orbit shakedown test of the three-man Apollo Command/Service Module and the first crewed launch for the Apollo program.
Mercury-Atlas 10 (MA-10) was a cancelled early crewed space mission, which would have been the last flight in NASA's Mercury program. It was planned as a three-day extended mission, to launch in late 1963; the spacecraft, Freedom 7-II, would have been flown by Alan Shepard, a veteran of the suborbital Mercury-Redstone 3 mission in 1961. However, it was cancelled after the success of the one-day Mercury-Atlas 9 mission in May 1963, to allow NASA to focus its efforts on the more advanced two-man Gemini program.
Project Gemini was the second United States human spaceflight program to fly. Conducted after the first American crewed space program, Project Mercury, while the Apollo program was still in early development, Gemini was conceived in 1961 and concluded in 1966. The Gemini spacecraft carried a two-astronaut crew. Ten Gemini crews and 16 individual astronauts flew low Earth orbit (LEO) missions during 1965 and 1966.
NASA Astronaut Group 2 was the second group of astronauts selected by the National Aeronautics and Space Administration (NASA). Their selection was announced on September 17, 1962. The group augmented the Mercury Seven. President John F. Kennedy had announced Project Apollo, on May 25, 1961, with the ambitious goal of putting a man on the Moon by the end of the decade, and more astronauts were required to fly the two-man Gemini spacecraft and three-man Apollo spacecraft then under development. The Mercury Seven had been selected to accomplish the simpler task of orbital flight, but the new challenges of space rendezvous and lunar landing led to the selection of candidates with advanced engineering degrees as well as test pilot experience.

NASA Astronaut Group 3 was a group of fourteen astronauts selected by NASA for the Gemini and Apollo program. Their selection was announced in October 1963. Seven were from the United States Air Force, four from the United States Navy, one was from the United States Marine Corps and two were civilians. Four died in training accidents before they could fly in space. All of the surviving ten flew Apollo missions; five also flew Gemini missions. Buzz Aldrin, Alan Bean, Gene Cernan and David Scott walked on the Moon.
The Kennedy Space Center Visitor Complex is the visitor center at NASA's Kennedy Space Center on Merritt Island, Florida. It features exhibits and displays, historic spacecraft and memorabilia, shows, two IMAX theaters, and a range of bus tours of the spaceport. The "Space Shuttle Atlantis" exhibit contains the Atlantis orbiter and the Shuttle Launch Experience, a simulated ride into space. The center also provides astronaut training experiences, including a multi-axial chair and Mars Base simulator. The visitor complex also has daily presentations from a veteran NASA astronaut. A bus tour, included with admission, encompasses the separate Apollo/Saturn V Center. There were 1.7 million visitors to the visitor complex in 2016.
The Space Task Group was a working group of NASA engineers created in 1958, tasked with managing America's human spaceflight programs. Headed by Robert Gilruth and based at the Langley Research Center in Hampton, Virginia, it managed Project Mercury and follow-on plans. After President John F. Kennedy set the goal in 1961 for the Apollo Program to land a man on the Moon and bring him back safely to Earth, NASA decided a much larger organization and a new facility was required to perform the Task Group's function, and it was transformed into the Manned Spacecraft Center, located in Houston, Texas.
