File:Skylab Payload Shroud Separation graphic (0101587).jpg

English: This artist's concept depicts the separation of the Skylab payload shroud. The payload shroud was both an environmental shield and an aerodynamic fairing. Attached to the forward end of the fixed airlock shroud, it protected the airlock, the docking adapter, and the solar observatory before and during launch. It also provided structural support for the solar observatory in the launch configuration. The payload shroud was jettisoned once Skylab reached orbit after separation of the S-II second stage of the Saturn V vehicle. Five major assemblies clustered together made up the orbiting space station called Skylab. The largest of these was the orbital workshop, that housed the crew quarters and a major experiment area. The airlock module, attached to the forward end of the workshop, enabled crewmembers to make excursions outside Skylab. The docking adapter, attached to the forward end of the airlock module, provided the docking port for the Apollo command and service module. The Apollo Telescope Mount was the first marned astronomical observatory designed for solar research from Earth orbit.
