Gemini 2 (Gemini-Titan 2; GT-2) was the second spaceflight of the American human spaceflight program Project Gemini.
 Gemini 2, like Gemini 1, was an unmanned mission intended as a test flight of the Gemini spacecraft.
 Unlike Gemini 1, which was placed into orbit, Gemini 2 made a suborbital flight, primarily intended to test the spacecraft's heat shield.
 It was launched on a Titan II GLV rocket.
 The spacecraft used for the Gemini 2 mission was later refurbished, and was subsequently launched on another suborbital flight, along with OPS 0855, as a test for the US Air Force Manned Orbital Laboratory.
 Gemini 2 was the first craft to make more than one spaceflight since the X-15, and the only one until Space Shuttle "Columbia" flew its second mission in 1981.
Gemini 5 (officially Gemini V) was a 1965 manned spaceflight in NASA's Gemini program.
 It was the third manned Gemini flight, the eleventh manned American flight, and the nineteenth spaceflight of all time, including two X-15 flights above 100 km .
 It was also the first time an American manned space mission held the world record for duration, set on August 26, 1965, by breaking the Soviet Union's previous record set by Vostok 5 in 1963.
Soyuz 9 (Russian: Союз 9 , "Union 9") was a 1970 Soviet manned space flight.
 The two-man crew of Andrian Nikolayev and Vitali Sevastyanov broke the five-year-old space endurance record held by Gemini 7, with their nearly 18-day flight.
 The mission paved the way for the Salyut space station missions, investigating the effects of long-term weightlessness on crew, and evaluating the work that the cosmonauts could do in orbit, individually and as a team.
 It was also the last flight of the first-generation Soyuz 7K-OK spacecraft, as well as the first manned space launch to be conducted at night.
 To date, Soyuz 9 marks the longest manned flight by a solo spacecraft.
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.
Barry Eugene "Butch" Wilmore (born December 29, 1962) is a NASA astronaut and United States Navy test pilot.
 He has had two spaceflights, the first of which was an 11-day Space Shuttle mission in November 2009, to the International Space Station.
 There were five other crew members launched with him on Space Shuttle "Atlantis" for the mission STS-129; Wilmore was designated as pilot.
 He most recently served as part of Expedition 41 to the International Space Station.
STS-95 was a Space Shuttle mission launched from Kennedy Space Center, Florida on 29 October 1998, using the orbiter "Discovery".
 It was the 25th flight of "Discovery" and the 92nd mission flown since the start of the Space Shuttle program in April 1981.
 It was a highly publicized mission due to former Project Mercury astronaut and United States Senator John H. Glenn, Jr.'s return to space for his second space flight.
 At age 77, Glenn became the oldest person, to date, to go into space.
 This mission is also noted for inaugurating ATSC HDTV broadcasting in the U.S., with live coast-to-coast coverage of the launch.
 In another first, Spain's Pedro Duque became the first Spaniard in space.
Soyuz 18 (Russian: Союз 18 , "Union 18") was a 1975 Soviet manned mission to Salyut 4, the second and final crew to man the space station.
 Pyotr Klimuk and Vitali Sevastyanov set a new Soviet space endurance record of 63 days and the mark for most people in space simultaneously (seven) was tied during the mission.
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.
Frank Frederick Borman II (born March 14, 1928), (Col, USAF, Ret.)
, is a retired United States Air Force pilot, aeronautical engineer, test pilot, and NASA astronaut, best remembered as the Commander of Apollo 8, the first mission to fly around the Moon, making him, along with crew mates Jim Lovell and Bill Anders, the first of only 24 humans to do so.
 Before flying on Apollo, he set a fourteen-day spaceflight endurance record on Gemini 7, and also served on the NASA review board which investigated the Apollo 1 fire.
 After leaving NASA, he was the Chief Executive Officer (CEO) of Eastern Air Lines from 1975 to 1986.
 Borman is a recipient of the Congressional Space Medal of Honor.
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.
