The Apollo spacecraft was a type of 20th century Earth spacecraft used by the United States of America during the 1960s and 1970s. The Apollo spacecraft, which consisted of three primary components, was propelled into space by means of a rocket. In the Apollo program, it was responsible for successfully placing a man in orbit of Earth and the moon, as well as conducting several successful moon landings. After the last mission on Luna, the spacecraft was responsible for transporting astronauts to the space station Skylab.
Several images depicting the various Apollo spacecraft components (such as the ascent engine cover, aft equipment bay, cabin heat exchanger shutter and cabin pressure relief valve control) was scanned by the Talosians as they reviewed the library computer files on board USS Enterprise in 2254.

Apollo Command/Service Module
The Apollo Command/Service Module (or CSM) was the primary mode of transportation for shuttling the astronauts between the Earth and moon, or for transporting astronauts to Skylab. The Command Module provided a compartment for the crew and the mission's equipment, while the Service Module provided the spacecrafts power and propulsion. The mission insignias for Apollo 1, Apollo 7, Apollo 9, Apollo 10, the Skylab program, and Skylab II included the command/service module in their designs.

Apollo Lunar Module
The Apollo Lunar Module (or LM) was a two person landing craft that was attached to the Command/Service Module, and when detached, was used to transport the crew to and from the surface of the moon. Lunar modules were first used with Apollo 9. The mission insignias for Apollo 9 and Apollo 10 included the lunar module in their designs. (ENT: "First Flight") The ascent and descent stages of the module carried fuel tanks filled with Aerozine 50.
