The Skylab (SL) was a
manned, orbiting spacecraft
composed of five parts, the
Apollo telescope mount
(ATM), the multiple
docking adapter (MDA),
the airlock module (AM),
the instrument unit (IU),
and the orbital workshop
(OWS). The Skylab was in
the form of a cylinder, with
the ATM being positioned
90 deg from the
longitudinal axis after
insertion into orbit. The
ATM was a solar
observatory, and it
provided attitude control and experiment pointing for the rest of the cluster. It was
attached to the MDA and AM at one end of the OWS. The retrieval and installation of
film used in the ATM was accomplished by astronauts during extravehicular activity
(EVA). The MDA served as a dock for the command and service modules, which served
as personnel taxis to the Skylab. The AM provided an airlock between the MDA and the
OWS, and contained controls and instrumentation. The IU, which was used only during
launch and the initial phases of operation, provided guidance and sequencing functions
for the initial deployment of the ATM, solar arrays, etc. The OWS was a modified Saturn
4B stage suitable for long duration manned habitation in orbit. It contained provisions
and crew quarters necessary to support three-person crews for periods of up to 84 days
each. All parts were also capable of unmanned, in-orbit storage, reactivation, and reuse.
This addon is geared for Orbiter 2005 edition and the latest Beta of REDSHIFT.
