december 1972
evans was selected as an astronaut by nasa as part of astronaut group 5 in 1966 and made his only flight into space as command module pilot aboard apollo 17 in december, 1972, the last crewed mission to the moon, with commander eugene cernan and lunar module pilot harrison schmitt. during the flight, he and five mice orbited the moon a record 75 times as his two crewmates descended to the surface. consequently, he is the last person to orbit the moon alone and holds the record for the most time spent in lunar orbit at 148 hours. in 1975 evans served as backup command module pilot for the apollo-soyuz test project mission.

preparations for a mission started a month in advance with the selection of the primary and back-up astronaut; they would practice together for the mission. for three days prior to launch, the astronaut went through a special diet to minimize his need for defecating during the flight. on the morning of the trip he typically ate a steak breakfast. after having sensors applied to his body and being dressed in the pressure suit, he started breathing pure oxygen to prepare him for the atmosphere of the spacecraft. he arrived at the launch pad, took the elevator up the launch tower and entered the spacecraft two hours before launch. once the astronaut was secured inside, the hatch was bolted, the launch area evacuated and the mobile tower rolled back. after this, the launch vehicle was filled with liquid oxygen. the entire procedure of preparing for launch and launching the spacecraft followed a time table called the countdown. it started a day in advance with a pre-count, in which all systems of the launch vehicle and spacecraft were checked. after that followed a 15-hour hold, during which pyrotechnics were installed. then came the main countdown which for orbital flights started 6½ hours before launch (t – 390 min), counted backwards to launch (t = 0) and then forward until orbital insertion (t + 5 min).
