The Apollo 11 Command Module, "Columbia," was the living quarters for the three-person crew during most of the first manned lunar landing mission in July 1969. On July 16, 1969, Neil Armstrong, Edwin "Buzz" Aldrin and Michael Collins were launched from Cape Kennedy atop a Saturn V rocket. This Command Module, no. 107, manufactured by North American Rockwell, was one of three parts of the complete Apollo spacecraft. The other two parts were the Service Module and the Lunar Module, nicknamed "Eagle." The Service Module contained the main spacecraft propulsion system and consumables while the Lunar Module was the two-person craft used by Armstrong and Aldrin to descend to the Moon's surface on July 20, 1969. The Command Module is the only portion of the spacecraft to return to Earth.
The Command/Service Module (CSM) was one of two spacecraft, along with the Lunar Module, used for the United States Apollo program which landed astronauts on the Moon. It was built for NASA by North American Aviation. It was launched by itself into suborbital and low Earth orbit test missions with the Saturn IB launch vehicle, and three times by itself and nine times with the Lunar Module as part of the Apollo spacecraft assembly on the larger Saturn V launch vehicle, which was capable of sending it to the Moon.
