Goals: Demonstrate the capabilities of astronauts, space vehicle, and mission-support facilities during a lunar mission and to evaluate lunar-module performance in the lunar environment. The mission was a full "dry run" for the Apollo 11 mission, in which all operations except the actual lunar landing were performed.
Commander: Thomas P. Stafford
Command module (Charlie Brown) pilot: John W. Young
Lunar module (Snoopy) pilot: Eugene A. Cernan
Accomplishments: All primary objectives were achieved. Apollo 10 conducted a full dress rehearsal for the upcoming Apollo 11 lunar-landing mission. In addition, the mission enabled the Manned Space Flight Network to provide a more accurate description of the irregular lunar gravitational field by tracking the spacecraft as it orbited the moon.
