Artist concept illustrating of Skylab Rescue Command Module

An artist's concept illustrating a cutaway view of the general arrangement of the Skylab Rescue Command Module (CM). The standard Skylab CM accommodates a crew of three with storage lockers on the aft bulkhead for resupply of experiment film and other equipment as well as the return of exposed film, data tapes and experiment samples. To convert the standard CM to a rescue vehicle, the storage lockers are removed and replaced with two crew couches in order to seat five crewmen. The rescue CM would then be launched with a crew of two.
