Apollo 11 was a spaceflight conducted by the United States from July 16 to July 24, 1969. It marked the first time in history that humans landed on the Moon. Commander Neil Armstrong and Lunar Module Pilot Buzz Aldrin landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC, and Armstrong became the first person to step onto the Moon's surface six hours and 39 minutes later, on July 21 at 02:56 UTC. Aldrin joined him 19 minutes later, and they spent about two and a quarter hours together exploring the site they had named Tranquility Base upon landing. Armstrong and Aldrin collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth as pilot Michael Collins flew the Command Module Columbia in lunar orbit, and were on the Moon's surface for 21 hours, 36 minutes before lifting off to rejoin Columbia.
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 from 1968 to 1972. 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.
Apollo 13 was the seventh crewed mission in the Apollo space program and the third meant to land on the Moon. The craft was launched from Kennedy Space Center on April 11, 1970, but the lunar landing was aborted after an oxygen tank in the service module (SM) ruptured two days into the mission, disabling its electrical and life-support system. The crew, supported by backup systems on the lunar module (LM), instead looped around the Moon in a circumlunar trajectory and returned safely to Earth on April 17. The mission was commanded by Jim Lovell, with Jack Swigert as command module (CM) pilot and Fred Haise as lunar module (LM) pilot. Swigert was a late replacement for Ken Mattingly, who was grounded after exposure to rubella.
Apollo 7 was the first crewed flight in NASA's Apollo program, and saw the resumption of human spaceflight by the agency after the fire that had killed the three Apollo 1 astronauts during a launch rehearsal test on January 27, 1967. The Apollo 7 crew was commanded by Walter M. Schirra, with command module pilot Donn F. Eisele and lunar module pilot R. Walter Cunningham.
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.
Moon landing conspiracy theories claim that some or all elements of the Apollo program and the associated Moon landings were hoaxes staged by NASA, possibly with the aid of other organizations. The most notable claim of these conspiracy theories is that the six crewed landings (1969–1972) were faked and that twelve Apollo astronauts did not actually land on the Moon. Various groups and individuals have made claims since the mid-1970s that NASA and others knowingly misled the public into believing the landings happened, by manufacturing, tampering with, or destroying evidence including photos, telemetry tapes, radio and TV transmissions, and Moon rock samples.
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.
Edgar Dean "Ed" Mitchell was a United States Navy officer and aviator, test pilot, aeronautical engineer, ufologist, and NASA astronaut. As the Lunar Module Pilot of Apollo 14 in 1971 he spent nine hours working on the lunar surface in the Fra Mauro Highlands region, and was the sixth person to walk on the Moon. He was the second Freemason to set foot on the Moon, after Buzz Aldrin.
Fred Wallace Haise Jr. is an American former NASA astronaut, engineer, fighter pilot with the U.S. Marine Corps and U.S. Air Force, and a test pilot. He is one of 24 people to have flown to the Moon, having flown as Lunar Module pilot on Apollo 13. He was slated to become the 6th person to walk on the Moon, but the Apollo 13 landing mission was aborted en route.
Dennis Anthony Tito is an American engineer and entrepreneur. During mid-2001, he became the first space tourist to fund his own visit to space, when he spent nearly eight days in orbit as a crew member of ISS EP-1, a visiting mission to the International Space Station. This mission was launched by the spacecraft Soyuz TM-32, and was landed by Soyuz TM-31.
Eugene Francis Kranz is an American aerospace engineer who served as NASA's second Chief Flight Director, directing missions of the Mercury, Gemini, and Apollo programs, including the first lunar landing mission, Apollo 11. He directed the successful efforts by the Mission Control team to save the crew of Apollo 13, and was portrayed in the 1995 film of the same name by actor Ed Harris. He characteristically wore a close-cut flattop hairstyle and the dapper "mission" vests (waistcoats) of different styles and materials made by his wife, Marta Kranz, for his Flight Director missions.
Richard Francis "Dick" Gordon Jr. was an American naval officer and aviator, test pilot, and NASA astronaut, and a football executive. He was one of 24 people to have flown to the Moon, as command module pilot of the Apollo 12 mission, which orbited the Moon 45 times. Gordon had already flown in space as the pilot of the 1966 Gemini 11 mission.
Alfred Merrill Worden was an American test pilot, engineer and NASA astronaut who was command module pilot for the Apollo 15 lunar mission in 1971. One of 24 people to have flown to the Moon, he orbited it 74 times in the command module (CM) Endeavour.
