Thirty-two "astronauts were assigned to fly in the "Apollo manned lunar landing program. Twenty-four of them left "Earth's orbit and flew around the "Moon on nine missions. (Of the other manned missions, "Apollo 1 did not launch and "Apollo 7 and "Apollo 9 were "low Earth orbit spacecraft testing missions). In addition, nine astronauts flew Apollo spacecraft in the Apollo Applications Programs "Skylab and "Apollo–Soyuz Test Project.

Twelve of these astronauts walked on the Moon's surface, and six of those drove "Lunar Roving Vehicles on the Moon. While three astronauts flew to the Moon twice, of which two landed, none landed on the Moon more than once. The nine Apollo missions to the Moon occurred between December 1968 and December 1972.

Apart from these twenty-four people who visited the Moon, no human being has gone beyond "low Earth orbit. They have, therefore, been farther from the Earth than anyone else. They are also the only people to have directly viewed the "far side of the Moon. The twelve who walked on the Moon are the only people ever to have set foot on an "astronomical object other than the Earth.

Of the twenty-four astronauts who flew to the Moon, two went on to command a Skylab mission, one commanded Apollo–Soyuz, one flew as commander for "Approach and Landing Tests of the "Space Shuttle, and two went on to command orbital Space Shuttle missions. A total of twenty-four NASA astronauts from the Apollo era flew on the Space Shuttle.


Prime crew members[edit]

NASA's Director of Flight Crew Operations during the "Gemini and Apollo programs was "Donald K. "Deke" Slayton, one of the original "Mercury Seven astronauts, who was medically grounded in September 1962 due to a minor cardiac arrythmia – paroxysmal atrial fibrillation. Slayton was responsible for making all Gemini and Apollo crew assignments. In March 1972, Slayton was restored to flight status, and flew on the 1975 "Apollo–Soyuz Test Project mission.

The prime crew members selected for actual missions are here grouped by their NASA astronaut selection groups, and within each group in the order selected for flight.

From the Mercury Seven[edit]

From "Astronaut Group 2[edit]

All of these astronauts flew on Gemini, and except for White, each commanded one Gemini and one Apollo mission:

From "Astronaut Group 3[edit]

NASA Astronaut Group 3

This was the first class of astronauts for which test pilot experience was not required, but military jet fighter pilot experience was acceptable.

Five of this group got their first spaceflight experience as second seat on Gemini:

The remaining six members of this group were selected for their first space flights on Apollo:

From "Astronaut Group 4[edit]

Harrison Schmitt (seated, center) became NASA's first scientist astronaut to fly in space.

In June 1965, NASA named a group of five scientist astronauts, the first group qualified by doctorate degrees rather than test or military fighter pilot experience.[4] Geologist "Harrison H. "Jack" Schmitt participated heavily in the geological training of the lunar landing astronauts, as well as assisting in the analysis of returned samples and the preparation of mission reports. In 1970, he was selected as Lunar Module Pilot for the Apollo 15 backup crew, and prime crew on Apollo 18. When program cutbacks canceled missions 18 through 20, NASA's lunar geological community insisted on having a geologist on the Moon, so Slayton reassigned Schmitt to "Apollo 17.

From "Astronaut Group 5[edit]

NASA Astronaut Group 5

NASA named a group of 19 more astronauts in April 1966. None had spaceflight experience before their Apollo mission.

Other astronauts who trained for Apollo but did not fly[edit]

Apollo astronauts who walked on the Moon[edit]

Twelve people have walked on the "Moon. Four of them are still living as of May 2018. All manned "lunar landings took place between July 1969 and December 1972 as part of the "Apollo program.

On each of the Apollo 17 "extravehicular activities (EVAs), "Harrison Schmitt was the second person out of, and the first person back into, the "lunar module. Schmitt is thus the 12th and last person to have stepped onto the Moon. "Eugene Cernan, as the second person to enter the lunar module on the final EVA, was the last person to have walked on the Moon.

Alan Shepard was the oldest person to walk on the Moon, at age 47 years and 80 days. "Charlie Duke was the youngest, at age 36 years and 201 days.

Jim Lovell and Fred Haise were scheduled to walk on the Moon during the "Apollo 13 mission, but the lunar landing was aborted following a major malfunction en route to the Moon. Haise was again scheduled to walk on the Moon as commander of Apollo 19, but "Apollo 18 and Apollo 19 were canceled on September 2, 1970.

"Joe Engle had trained on the backup crew for "Apollo 14 to explore the Moon with Cernan, but Engle was replaced by Schmitt on the primary crew for "Apollo 17. Schmitt had previously been crewed with "Apollo 12 "command module pilot "Dick Gordon in anticipation of Apollo 18, but Schmitt replaced Engle on Apollo 17 after the cancellation of Apollo 18 and Apollo 19, leaving Gordon as the last Apollo astronaut to train extensively for lunar exploration without ever landing on the Moon.

Apollo astronauts who flew to the Moon without landing[edit]

Besides the 12 people who have walked on the Moon, 12 more have flown to within 0.001 "lunar distance of its surface. During each of the six missions with successful lunar landings, one astronaut remained in lunar orbit while the other two landed. In addition, the three-person crews of "Apollo 8 and "Apollo 10 also entered lunar orbit, and the crew of "Apollo 13 looped around the Moon on a "free-return trajectory.

All nine manned missions to the Moon took place as part of the "Apollo program over a period of just under four years, from 21 December 1968 to 19 December 1972. The 24 people who have flown to the Moon are the only people who have travelled beyond "low Earth orbit. Twelve of them are still living as of May 2018.

"Jim Lovell, "John Young, and "Eugene Cernan are the only three people to have flown to the Moon twice. Young and Cernan each set foot on it during their respective second lunar missions, while Lovell is the only person to have flown to the Moon twice without landing.

During Cernan's first lunar mission on Apollo 10, he tied the present record set by "Bill Anders on Apollo 8 as the youngest person to fly to the Moon. Each was 35 years and 65 days old on his launch date and 35 years and 68 days old when he entered lunar orbit. The oldest person to fly to the Moon was "Alan Shepard, who walked on its surface during the "Apollo 14 mission. Shepard was 47 years and 74 days old on his launch date and 47 years and 78 days old when he entered lunar orbit.

Because of Apollo 13's free-return trajectory, Lovell, "Jack Swigert and "Fred Haise flew higher above the Moon's "180° meridian (opposite Earth) than anyone else has flown (254 km/158 mi). Coincidentally, due to the Moon's distance from Earth at the time, they simultaneously set the present record for humans' greatest distance from Earth, reaching an altitude of 400,171 km (248,655 mi) above sea level at "0:21 UTC on 15 April 1970.
