The Apollo program, also known as Project Apollo, was the third United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which succeeded in preparing and landing the first humans 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) failed two days into the mission. The crew instead looped around the Moon 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 9 was the third human spaceflight in NASA's Apollo program. Flown in low Earth orbit, it was the second crewed Apollo mission that the United States launched via a Saturn V rocket, and was the first flight of the full Apollo spacecraft: the command and service module (CSM) with the Lunar Module (LM). The mission was flown to qualify the LM for lunar orbit operations in preparation for the first Moon landing by demonstrating its descent and ascent propulsion systems, showing that its crew could fly it independently, then rendezvous and dock with the CSM again, as would be required for the first crewed lunar landing. Other objectives of the flight included firing the LM descent engine to propel the spacecraft stack as a backup mode, and use of the portable life support system backpack outside the LM cabin.
Edward Higgins White II was an American aeronautical engineer, United States Air Force officer, test pilot, and NASA astronaut. He was a member of the crews of Gemini 4 and Apollo 1.
Gemini 3 was the first crewed mission in NASA's Project Gemini and was the first time two American astronauts flew together into space. On March 23, 1965, astronauts Gus Grissom and John Young flew three low Earth orbits in their spacecraft, which they nicknamed Molly Brown. It was the first U.S. mission in which the crew fired thrusters to change the size and shape of their orbit, a key test of spacecraft maneuverability vital for planned flights to the Moon. It was also the final crewed flight controlled from Cape Kennedy Air Force Station in Florida, before mission control functions were moved to a new control center at the newly opened Manned Spacecraft Center in Houston, Texas.
David Randolph Scott is an American retired test pilot and NASA astronaut who was the seventh person to walk on the Moon. Selected as part of the third group of astronauts in 1963, Scott flew to space three times and commanded Apollo 15, the fourth lunar landing; he is one of four surviving Moon walkers and the last surviving crew member of Apollo 15.
Russell Louis "Rusty" Schweickart is an American aeronautical engineer, and a former NASA astronaut, research scientist, U.S. Air Force fighter pilot, as well as a former business executive and government executive.
James Arthur Lovell Jr. is an American retired astronaut, naval aviator, test pilot and mechanical engineer. In 1968, as command module pilot of Apollo 8, he became, with Frank Borman and William Anders, one of the first three astronauts to fly to and orbit the Moon. He then commanded the Apollo 13 lunar mission in 1970 which, after a critical failure en route, circled the Moon and returned safely to Earth.
Clifton Curtis Williams Jr., was an American naval aviator, test pilot, mechanical engineer, major in the United States Marine Corps, and NASA astronaut, who was killed in a plane crash; he never went into space. The crash was caused by a mechanical failure in a NASA T-38 jet trainer, which he was piloting to visit his parents in Mobile, Alabama. The failure caused the flight controls to stop responding, and although he activated the ejection seat, it did not save him. He was the fourth astronaut from NASA's Astronaut Group 3 to have died, the first two having been killed in separate T-38 flights, and the third in the Apollo 1 fire earlier that year. The aircraft crashed in Florida near Tallahassee within an hour of departing Patrick AFB.
James Alton McDivitt is an American former test pilot, United States Air Force (USAF) pilot, aeronautical engineer, and NASA astronaut who flew in the Gemini and Apollo programs. He joined the USAF in 1951 and flew 145 combat missions in the Korean War. In 1959, after graduating first in his class with a Bachelor of Science degree in Aeronautical Engineering from the University of Michigan through the U.S. Air Force Institute of Technology (AFIT) program, he qualified as a test pilot at the Air Force Experimental Flight Test Pilot School and Aerospace Research Pilot School, and joined the Manned Spacecraft Operations Branch. By September 1962, McDivitt had logged over 2,500 flight hours, of which more than 2,000 hours were in jet aircraft. This included flying as a chase pilot for Robert M. White's North American X-15 flight on July 17, 1962, in which White reached an altitude of 59.5 miles (95.8 km) and became the first X-15 pilot to be awarded Astronaut Wings.
Project Gemini was NASA's second human spaceflight program. Conducted between projects Mercury and Apollo, Gemini started 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 3—'The Fourteen'—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.
Several planned missions of the Apollo crewed Moon landing program of the 1960s and 1970s were canceled for a variety of reasons, including changes in technical direction, the Apollo 1 fire, hardware delays, and budget limitations. After the landing by Apollo 12, Apollo 20, which would have been the final crewed mission to the Moon, was canceled to allow Skylab to launch as a "dry workshop". The next two missions, Apollos 18 and 19, were later canceled after the Apollo 13 incident and further budget cuts. Two Skylab missions also ended up being canceled. Two complete Saturn Vs ended up going unused and are currently on display in the United States.
The Apollo 15 postal covers incident, a 1972 NASA scandal, involved the astronauts of Apollo 15, who carried about 400 unauthorized postal covers into space and to the Moon's surface on the Lunar Module Falcon. Some of the envelopes were sold at high prices by West German stamp dealer Hermann Sieger, and are known as "Sieger covers". The crew of Apollo 15, David Scott, Alfred Worden, and James Irwin, agreed to take payments for carrying the covers; though they returned the money, they were reprimanded by NASA. Amid much press coverage of the incident, the astronauts were called before a closed session of a Senate committee and never flew in space again.
A mission patch is a cloth reproduction of a spaceflight mission emblem worn by astronauts and other personnel affiliated with that mission. It is usually executed as an embroidered patch. The term space patch is mostly applied to an emblem designed for a crewed space mission. Traditionally, the patch is worn on the space suit that astronauts and cosmonauts wear when launched into space. Mission patches have been adopted by the crew and personnel of many other space ventures, public and private.
Astrophilately is a branch of philately which deals with the collection of stamps and postmarked envelopes related to spaceflight. It is the intersection of space and postal history. Covers cancelled on the date and at a post office near the controlling agency are used in postal exhibits to share the development and conquest of the cosmos.
The United States Astronaut Hall of Fame, located inside the Kennedy Space Center Visitor Complex Heroes & Legends building on Merritt Island, Florida, honors American astronauts and features the world's largest collection of their personal memorabilia, focusing on those astronauts who have been inducted into the Hall. Exhibits include Wally Schirra's Sigma 7 space capsule from the fifth manned Mercury mission and the Gemini IX spacecraft flown by Gene Cernan and Thomas P. Stafford in 1966.
NASA Astronaut Group 7 was a group of seven astronauts accepted by the National Aeronautics and Space Administration (NASA) on August 14, 1969. It was the last group to be selected during the Project Apollo era, and the first since the Mercury Seven in which all members were active-duty military personnel, and all made flights into space.
The Personal Preference Kit (PPK) is a container used to carry the personal items of astronauts during the Gemini, Apollo, and Space Shuttle, and International Space Station programs. Items that astronauts choose to carry into space are approved by NASA management and stored in PPKs. Information on the contents of kits are usually kept private by the astronaut, although some contents have been put on display or given as awards to contributors to space programs.
