This cue card directly from the Gene Cernan collection was flown to the lunar surface on 17 aboard the spacecraft Challenger and spent time on the moon in the Taurus-Littrow valley during the last Apollo lunar landing mission in December 1972.
The RCS / COMMON cue card would have been used if the astronauts had experienced a Reaction Control System failure in the Lunar Module during the mission. It contains failure indications, workarounds to solve for failures, and other operating information about the RCS system onboard the Lunar Module.
Cue cards like this one are critical to allowing the crew to react quickly and accurately to contingencies that arise during the mission.
