Joseph Richard "Joe" Tanner (born January 21, 1950) is an American instructor at the University of Colorado Boulder, mechanical engineer, a former naval officer and aviator, and a former NASA astronaut.
 He was born in Danville, Illinois.
 He is unusual among astronauts as he did not have a background in flight test nor did he earn any advanced academic degrees.
 Typically those who did not do military flight test have an M.D. or Ph.D., if not a master's, whereas Tanner's path to becoming an astronaut followed operational military flying and then into NASA for operational jet training before being selected into the NASA Astronaut Corps in 1992, following an unsuccessful application in 1987.
Charles Gordon Fullerton (October 11, 1936 – August 21, 2013) was a United States Air Force colonel, a USAF and NASA astronaut, and a research pilot at NASA's Dryden Flight Research Facility, Edwards, California.
 His assignments included a variety of flight research and support activities piloting NASA's B-52 launch aircraft, the Boeing 747 Shuttle Carrier Aircraft (SCA), and other multi-engine and high performance aircraft.
 Fullerton, who logged more than 380 hours in space flight, was a NASA astronaut from September 1969 until November 1986 when he joined the research pilot office at Dryden.
 In July 1988, he completed a 30-year career with the U.S. Air Force and retired as a colonel.
 He continued in his position of NASA research pilot as a civilian.
 Fullerton and his wife and their two children lived in Lancaster, California.
Andrew "Andy" Sydney Withiel Thomas, AO (born 18 December 1951 in Adelaide, South Australia) is an Australian-born American aerospace engineer and a NASA astronaut.

Theodore Cordy "Ted" Freeman (February 18, 1930 – October 31, 1964), was an American aeronautical engineer, U.S. Air Force officer, test pilot, and NASA astronaut.
 Selected in third group of NASA astronauts in 1963, he was killed a year later in the crash of a T-38 jet, marking the first fatality among the NASA Astronaut Corps.
 At the time of his death, he held the rank of captain.

 He was born in Lorain, Ohio, but considered Westlake, Ohio his hometown.
 Overmyer was selected by the United States Air Force as an astronaut for its Manned Orbiting Laboratory in 1966.
 Upon cancellation of this program in 1969, he became a NASA astronaut and served support crew duties for the Skylab program and Apollo-Soyuz Test Project.
 In 1976, he was assigned to the Space Shuttle program, and flew as pilot on STS-5 in 1982, and as commander on STS-51-B in 1985.
 He was selected as a lead investigator into the Space Shuttle "Challenger" disaster, and retired from NASA in 1986.
 Ten years later, Overmyer died in Duluth, Minnesota while testing the Cirrus VK-30 composite homebuilt aircraft.
Steven Ray Swanson (born December 3, 1960 in Syracuse, New York) is an American engineer and a retired NASA astronaut.
 He is married and has three children.
 He has received numerous awards and honors.

 Prior to becoming a NASA astronaut, Swanson worked for GTE in Phoenix, Arizona, as a software engineer.
 Swanson has flown 2 shuttle flights, STS-117 and STS-119.
 He has logged over 643 hours in space and completed 4 spacewalks totaling 26 hours and 14 minutes.
 Swanson has also served in other roles at NASA, such as a CAPCOM for both International Space Station and Space Shuttle missions.
Randolph James "Komrade" Bresnik (born September 11, 1967) is an officer in the United States Marine Corps and a NASA astronaut.

 He completed his training on February 10, 2006 and was assigned to STS-119, which flew from March 15 to March 28, 2009 to deliver the final set of solar arrays to the International Space Station.
 Acaba served as a Flight Engineer aboard the International Space Station, having launched on May 15, 2012.
 He arrived at the space station on May 17 and returned to Earth on September 17, 2012 at 6:53am Moscow Standard Time when touchdown was officially recorded by the Russian Federal Space Agency.
 Acaba returned to the International Space Station in 2017 as a member of Expedition 53/54.
