It is commonly referred to by its primary function—for example the "command module" used in the Apollo lunar missions. More recently, the term has been used to describe a distinct pressurized, crewed section of an orbiting spacecraft, suitable for conducting science, applications, and technology activities. An example of this would be the Spacelab module in the Space Transportation System.

Early Use of Modules

Modular construction was used in many early piloted spacecraft to minimize the size and weight of the re-entry vehicle and to ease assembly of the spacecraft. Modules can be constructed and tested independently of other sections and then integrated into the rest of the spacecraft at a later stage. Completion of the International Space Station (ISS) depends on this technique of modular construction, as...
