Editing List of Apollo astronauts (section)

== Apollo astronauts who walked on the Moon ==
Twelve men walked on the [[Moon]] during six [[Moon landing]]s of the [[Apollo program]] between July 1969 and December 1972. All landed on the surface only once, and five missions consisted of two or more surface [[extravehicular activity|extravehicular activities (EVAs)]]. Four of them are alive {{As of|2025|1|lc=y}} with an average age of {{Rounddown|(0

years. Most astronauts at that time came from the military services and were considered to be on active duty during their NASA service. The few exceptions were considered civilian NASA astronauts, regardless of any prior military service.

On the last of their three Apollo 17 EVAs, [[Harrison Schmitt]] stepped out of the [[Apollo Lunar Module]] onto the surface of the Moon after [[Gene Cernan]], and is therefore the 12th and most recent person to have stepped out onto the Moon. When they re-entered the lunar module Cernan stepped in last, and is therefore 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. [[Charles 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 an explosion in the spacecraft [[service module]] en route to the Moon. Haise was again scheduled to walk on the Moon as commander of Apollo 19, but [[Canceled Apollo missions#Follow-on lunar missions|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 he was replaced by Schmitt on the primary crew for [[Apollo 17]]. Schmitt had previously been crewed with [[Apollo 12]] [[Apollo Command/Service Module#Command Module (CM)|Command Module]] pilot [[Richard F. Gordon Jr.|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.
