Question:  Charles "Pete" Conrad Jr., an American astronaut, set an eight-day space endurance record along with his Command Pilot Gordon Cooper, one of the seven original astronauts in the first manned space program of the United States called what?

full_context: Document 1: Project Mercury: 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 U.S. Air Force by the newly created civilian space agency NASA, it conducted twenty unmanned developmental flights (some using animals), and six successful flights by astronauts. The program, which took its name from Roman mythology, cost $277 million in 1965 US dollars, and 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.
Document 2: Gordon Cooper: Leroy Gordon "Gordo" Cooper Jr. (March 6, 1927 – October 4, 2004), (Col, USAF), better known as Gordon Cooper, was an American aerospace engineer, test pilot, United States Air Force pilot, and one of the seven original astronauts in Project Mercury, the first manned space program of the United States.
Document 3: Mercury-Atlas 7: Mercury-Atlas 7, launched May 24, 1962, was the fourth flight of Project Mercury, the first manned space program of the United States. The Mercury spacecraft, named Aurora 7, made three Earth orbits, piloted by astronaut Scott Carpenter. He was the sixth human and the fourth American in space.
Document 4: Mercury Seven: The Mercury Seven were the group of seven Mercury astronauts announced by NASA on April 9, 1959. They are also referred to as the Original Seven or Astronaut Group 1. They piloted the manned spaceflights of the Mercury program from May 1961 to May 1963. These seven original American astronauts were Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard, and Deke Slayton.
Document 5: Alan Bean: Alan LaVern Bean (born March 15, 1932), (CAPT, USN, Ret.), is an American former naval officer and Naval Aviator, aeronautical engineer, test pilot, and NASA astronaut; he was the fourth person to walk on the Moon. He was selected to become an astronaut by NASA in 1963 as part of Astronaut Group 3. He made his first flight into space aboard Apollo 12, the second manned mission to land on the Moon, at the age of thirty-seven years in November 1969. He made his second and final flight into space on the Skylab 3 mission in 1973, the second manned mission to the Skylab space station. After retiring from the United States Navy in 1975 and NASA in 1981, he pursued his interest in painting, depicting various space-related scenes and documenting his own experiences in space as well as that of his fellow Apollo program astronauts.
Document 6: Pete Conrad: Charles "Pete" Conrad Jr. (June 2, 1930 – July 8, 1999), (Captain, USN), was an American NASA astronaut, naval officer and aviator, test pilot, and during the Apollo 12 mission became the third man to walk on the Moon. He set an eight-day space endurance record along with his Command Pilot Gordon Cooper on the Gemini 5 mission, and commanded the Gemini 11 mission. After Apollo, he commanded the Skylab 2 mission (the first manned one), on which he and his crewmates repaired significant launch damage to the Skylab space station. For this, President Jimmy Carter awarded him the Congressional Space Medal of Honor in 1978.
Document 7: Russell Colley: Russell Colley was a U. S. mechanical engineer who played a role in creating the spacesuits worn by the Project Mercury astronauts, including fitting Alan B. Shepard Jr. for his historic ride as America's first man in space on May 5, 1961.
Document 8: Mercury-Redstone 3: 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 manned flight of Project Mercury, the objective of which was to put an astronaut into orbit around the Earth and return 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.
Document 9: Apollo 12: Apollo 12 was the sixth manned flight in the United States Apollo program and the second to land on the Moon (an H type mission). It was launched on November 14, 1969, from the Kennedy Space Center, Florida, four months after Apollo 11. Mission commander Charles "Pete" Conrad and Lunar Module Pilot Alan L. Bean performed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit. The landing site for the mission was located in the southeastern portion of the Ocean of Storms.
Document 10: Wally Schirra: Walter Marty "Wally" Schirra Jr. (March 12, 1923 – May 3, 2007), (CAPT, USN), was an American naval officer and aviator, aeronautical engineer, test pilot, and one of the original seven astronauts chosen for Project Mercury, United States first effort to put humans in space. He flew the six-orbit, nine-hour Mercury-Atlas 8 mission on October 3, 1962, becoming the fifth American, and the ninth human, to ride a rocket into space. In the two-man Gemini program, he achieved the first space rendezvous, station-keeping his Gemini 6A spacecraft within 1 ft of the sister Gemini 7 spacecraft in December 1965. In October 1968, he commanded Apollo 7, an 11-day low Earth orbit shakedown test of the three-man Apollo Command/Service Module. He was the first person to go into space three times, and the only person to have flown in Mercury, Gemini, and Apollo, logging a total of 295 hours and 15 minutes in space. He retired from the U.S. Navy at the rank of Captain and from NASA after his Apollo flight, becoming a consultant to CBS News for its coverage of the subsequent Apollo flights. He joined Walter Cronkite as co-anchor for the seven Moon landing missions.
Document 11: Richard F. Gordon Jr.: Richard Francis "Dick" Gordon Jr. (born October 5, 1929), (Capt, USN, Ret.), is a former American naval officer and aviator, chemist, test pilot, and NASA astronaut. He is one of only 24 people to have flown to the Moon, as the Command Module Pilot for the Apollo 12 mission.
Document 12: Deke Slayton: Donald Kent "Deke" Slayton (March 1, 1924 – June 13, 1993), (Major, USAF) was an American World War II pilot, aeronautical engineer, test pilot who was selected as one of the original NASA Mercury Seven astronauts, and became NASA's first Chief of the Astronaut Office.
Document 13: Pete Conrad: Charles "Pete" Conrad Jr. (June 2, 1930 – July 8, 1999), (Captain, USN), was an American NASA astronaut, naval officer and aviator, test pilot, and during the Apollo 12 mission became the third man to walk on the Moon. He set an eight-day space endurance record along with his Command Pilot Gordon Cooper on the Gemini 5 mission, and commanded the Gemini 11 mission. After Apollo, he commanded the Skylab 2 mission (the first manned one), on which he and his crewmates repaired significant launch damage to the Skylab space station. For this, President Jimmy Carter awarded him the Congressional Space Medal of Honor in 1978.
Document 14: Michael Collins (astronaut): Michael Collins (born October 31, 1930) (Major General, USAF, Ret.), is an American former astronaut and test pilot. Selected as part of the third group of fourteen astronauts in 1963, he flew into space twice. His first spaceflight was on Gemini 10, in which he and Command Pilot John Young performed two rendezvous with different spacecraft and Collins undertook two extra-vehicular activities (EVAs). His second spaceflight was as the Command Module Pilot for Apollo 11. While he stayed in orbit around the Moon, Neil Armstrong and Buzz Aldrin left in the Lunar Module to make the first manned landing on its surface. He is one of 24 people to have flown to the Moon.
Document 15: Gus Grissom: Lieutenant Colonel Virgil Ivan "Gus" Grissom (April 3, 1926 – January 27, 1967) was one of the original NASA Project Mercury astronauts, a United States Air Force test pilot, and a mechanical engineer.
