Apollo spacecraft

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 was scanned by the Talosians as they reviewed the library computer files on board USS Enterprise (NCC-1701) in 2254. ( remastered)

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. 

Commodore Maxwell Forrest had a model of the Apollo Command/Service Module in his office at Starfleet Command in 2143. 

Wesley Crusher had a model of the Apollo Command/Service Module in his quarters at Starfleet Academy in 2368. 

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. 

In the year 2000, Shannon O'Donnell had a model of the Apollo Lunar Module suspended from the rear-view mirror of her Ford Motor Company LTD Country Squire. 

In an illusion created by Barash for William T. Riker, Riker, who was the captain of the USS Enterprise (NCC-1701-D), had a model of the Apollo Lunar Lander in his ready room.
