Only a handful of men have stood on the moon and looked up at Earth. NASA landed six missions and 12 astronauts on the moon during the Apollo program. Six others remained in lunar orbit aboard their Apollo spacecraft command modules. One mission, Apollo 13, was aborted in mid-flight. Here is a snapshot of NASA's six successful moon-landing crews and where they are now:
Neil Armstrong: Commander, Apollo 11, the first manned moon landing flight, which landed on the lunar surface on July 20, 1969. Armstrong was a Navy aviator and later a test pilot for NASA's precursor agency, the National Advisory Committee for Aeronautics, where he tested the X-15 rocket plane, among other experimental aircraft. He joined NASA in 1962 and commanded the Gemini 8 mission in 1966 to perform the first space docking in orbit. Armstrong left NASA in 1971 to teach aerospace engineering at the University of Cincinnati and chair an electronic systems company. Armstrong died Aug. 25, 2012, of complications related to recent surgery at age 82. [Photos: Neil Armstrong — American Icon Remembered]
Buzz Aldrin: Lunar module pilot, Apollo 11. A U.S Air Force pilot before joining NASA in 1963, Aldrin first launched into space on the Gemini 12 mission in 1966 to test spacewalking procedures, including new restraints attached to the outside of the space capsule, and new training techniques. After becoming the second man to walk on the moon, Aldrin resigned from NASA in July 1971. Post-NASA, he has written numerous books, given lectures around the world, and even participated in the reality television show "Dancing With the Stars." Aldrin is currently the president of Starcraft Enterprise, a company he founded to promote his vision for the future of space exploration.
Michael Collins: Command module pilot, Apollo 11. Collins stayed on the Columbia command module while Armstrong and Aldrin took the Eagle lunar lander down to the moon's surface. Apollo 11 was Collins' second spaceflight, after the Gemini 10 mission in 1966. On that flight, Collins served as pilot during a successful rendezvous and docking with a separately launched unmanned spacecraft called Agena. Before joining NASA in 1963, Collins was an experimental flight test officer in the U.S. Air Force, logging approximately 5,000 hours flying time. He retired as a brigadier general from the Air Force, and left NASA in 1970 to work for the U.S. State Department, and then to become the director of the Smithsonian's National Air & Space Museum. In 1980, Collins left the Smithsonian, joining the LTV Aerospace company, and then started his own consulting firm in 1985. He has written several books and paints watercolors.
Charles "Pete" Conrad: Commander, Apollo 12. Conrad headed up the second lunar landing mission, Apollo 12, in November 1969. Conrad became the third person to walk on the moon, and spent more than a day exploring the lunar surface. Apollo 12 was Conrad's third spaceflight, following his turns on the Gemini 5 and Gemini 11 missions. A test pilot for the U.S. Navy, Conrad joined NASA in 1962, and retired in 1973 after commanding the Skylab 2 mission on the first American space station. After his military and NASA career, Conrad worked at the American Television and Communications Corporation (ATC) and the McDonnell Douglas Corporation. He died in 1999, following a motorcycle accident in Ojai, Calif.
Alan Bean: Lunar module pilot, Apollo 12. Bean's first spaceflight was Apollo 12, during which he spent more than a day on the surface of the moon with Pete Conrad. A captain the U.S. Navy, Bean joined NASA in 1963, and followed up Apollo 12 as commander of the Skylab 3 mission in 1973. He retired from NASA in 1981 to concentrate on painting, saying he was inspired to communicate his space experiences through art. In 2009, to celebrate the 40th anniversary of the first moon landing, many of Bean's works were displayed at the Smithsonian National Air and Space Museum in Washington, D.C. Bean died May 26, 2018, after an illness. He was 86.
Richard F. "Dick" Gordon: Command module pilot, Apollo 12. On Apollo 12, Gordon stayed inside the command module Yankee Clipper, photographing potential future lunar landing sites while Conrad and Bean walked on the moon. Gordon, a captain in the U.S. Navy, was selected as an astronaut in 1963, and served as pilot for the Gemini 11 mission in September 1966. He retired from NASA and the Navy in 1972, and went on to work for the New Orleans Saints Professional Football Club; Energy Developers, Limited (EDL); Resolution Engineering and Development Company (REDCO); and Astro Sciences Corporation. Gordon died November 6, 2017. He was 88. [NASA's 17 Apollo Moon Missions in Pictures]
Alan Shepard: Commander, Apollo 14. Prior to commanding Apollo 14 in 1971, Shepard became the first American to reach space when he rode in the Freedom 7 spacecraft on May 5, 1961, under NASA's Mercury program. Apollo 14 marked his second spaceflight, following a stint as chief of NASA's astronaut office, a job he resumed after his moon mission. During his walk on the moon, he famously hit two golf balls and watched them soar in the low lunar gravity. Shepard, a rear admiral of the U.S. Navy, left NASA and the Navy in 1974. After NASA, Shepard wrote a book about his space experiences, served on the boards of various corporations, and helped lead the Mercury Seven Foundation, which awarded college scholarships for science. He died in 1998 of leukemia. [Photos: Freedom 7, America's First Manned Spaceflight]
Edgar Mitchell: Lunar module pilot, Apollo 14. Mitchell's first flight to space on Apollo 14 sent him to the moon with Alan Shepard for a total of 216 hours and 42 minutes in space. The U.S. Navy captain retired from NASA and the Navy after that mission in 1972, going on to found the Institute of Noetic Sciences, dedicated to the study of consciousness. He wrote books on mystical experiences and psychic exploration. Mitchell died February 4, 2016.
Stuart Roosa: Command module pilot, Apollo 14. On his first and only trip to space, Roosa piloted the command module Kitty Hawk, making observations of the moon from orbit while Shepard and Mitchell walked on the lunar surface. Roosa joined NASA in 1966 from the U.S. Air Force, and worked on the space shuttle program after the Apollo flights ended. After his retirement from NASA in 1976, Roosa then worked for U.S. Industries, Inc., for a commercial real estate firm called Charles Kenneth Campbell Investments, and was president and owner of Gulf Coast Coors, Inc., a beer distributor. Roosa died in 1994, due to complications of pancreatitis.
David Scott: Commander, Apollo 15. During the fourth manned moon-landing mission, Apollo 15, Scott and Irwin became the first people to drive a lunar rover around the surface of the moon. When he commanded the mission in 1971, Scott was already a space veteran, having served aboard the Gemini 8 mission in 1966 with Neil Armstrong, and then the Apollo 9 mission in 1969. After joining NASA in 1963, Scott eventually logged a total of 546 hours and 54 minutes in space. Following his work as an astronaut, Scott served as director of NASA's Dryden Flight Research Center at Edwards, California. He is a retired colonel in the U.S. Air Force.

James Irwin: Lunar module pilot, Apollo 15. Irwin's first and only flight to space was on Apollo 15, during which he walked around the moon's Hadley Rille and Apennine Mountains, collecting 171 lbs. (77.5 kilograms) of moon rocks with Scott. Irwin, a retired colonel in the U.S. Air Force, joined NASA in 1966. He left the space agency after his Apollo 15 flight in 1972, to become a preacher, and formed a religious organization called High Flight Foundation in Colorado Springs, Colo. Irwin died in 1991 of a heart attack.
Alfred Worden: Command module pilot, Apollo 15. As a test pilot, Worden was selected as an astronaut by NASA in 1966. He piloted Apollo 15's command module Endeavour while Scott and Irwin walked on the moon's surface. Following his space flight, Worden worked as a scientist at NASA's Ames Research Center in California, and ultimately retired from NASA in 1975. He went on to work at Maris Worden Aerospace, Inc., and BG Goodrich Aerospace.
John W. Young: Commander, Apollo 16. Young led the fifth manned moon landing mission, Apollo 16, in April 1972, when he and Charlie Duke explored the lunar highlands at Descartes, collected 200 lbs. (90.7 kg) of moon rocks, and drove more than 16 miles (24.75 kilometers) in the lunar rover. Young joined NASA in 1962 as a pilot in the U.S. Navy, and flew on six separate space missions. He flew on the first manned Gemini mission, Gemini 3, in 1965, and then on the Gemini 10 mission in 1966. Young then served as command module pilot of Apollo 10, which orbited the moon in 1969, but did not land. Following the Apollo program, Young went on to fly on two space shuttle missions, STS-1 — the first ever space shuttle flight — in 1981 and STS-9 in 1983. Overall, Young logged 835 hours in space, and worked at NASA until retiring in 2004. He died January 5, 2018.
Charles Duke: Lunar module pilot, Apollo 16. A retired brigadier general in the U.S. Air Force, Charlie Duke joined NASA in 1966 and flew on one space mission, Apollo 16, before retiring from NASA in 1975. During the Apollo 16 mission, Duke and Young deployed a cosmic ray detector and an ultraviolet camera on the lunar surface. After NASA, Duke pursued business opportunities, founding the Duke Investments Charlie Duke Enterprises firms. He is also president of the Duke Ministry for Christ.
Thomas "Ken" Mattingly: Command module pilot, Apollo 16. Mattingly joined NASA in 1966 and was due to make his first flight to space on the Apollo 13 mission, but was removed from the crew 72 hours before launch because he had been exposed to the German measles. Mattingly was reassigned to the Apollo 16 mission. Mattingly piloted the command module Casper, working on photographic and geochemical mapping of a belt around the lunar equator. Following Apollo 16, Mattingly flew on two space shuttle flights, STS-4 and STS-51C, before retiring from NASA in 1985.
Eugene Cernan: Commander, Apollo 17. Cernan had made two flights to space — on Gemini 9 in 1966 and on Apollo 10 in 1969 — before leading the sixth and last lunar landing mission, Apollo 17, in December 1972. This excursion to the moon marked the longest lunar landing flight, with Cernan and Harrison Schmitt spending more than three days on the moon's surface. Cernan was the last man to leave his footprints on the surface of the moon. A captain in the U.S. Navy, he retired from NASA and the military in 1975. He worked at Coral Petroleum, Inc., and then founded his own consulting company, the Cernan Corporation. He also served as Chairman of the Board of Johnson Engineering Corporation, which has helped NASA design trainers and equipment for space exploration. He died on January 16, 2017.
Harrison Schmitt: Lunar module pilot, Apollo 17. Schmitt, a trained geologist, was the only astronaut without military experience to walk on the moon, and helped train all Apollo moonwalking crews in geology. He was selected by NASA as a scientist-astronaut in 1965. Apollo 17 was Schmitt's only flight to space, but he continued to work at NASA after the Apollo program as chief of the scientist-astronauts and then as NASA assistant administrator for energy programs. In 1975, Schmitt resigned from NASA to run for election in the U.S. Senate in New Mexico, where he won as a Republican and served a six-year term.
Ronald Evans: Command module pilot, Apollo 17. While Cernan and Schmitt walked on the lunar surface, Evans stayed in lunar orbit aboard the command module America. During the flight, he completed a spacewalk to retrieve three camera cassettes and make an inspection of the capsule's equipment bay area. He still holds the record of more time spent in lunar orbit than anyone else in the world. Evans became an astronaut in 1966. In 1976, he retired as a captain in the U.S. Navy, but stayed on at NASA working on the space shuttle program in the operations and training group and within the astronaut office. He retired from NASA in 1977 to work as an executive in the coal industry. Evans died in 1990 of a heart attack.
