Marshall Space Flight Center maintained
a 1G trainer during the Skylab program. Upon the completion of the manned
portion of the program, the trainer was moved the the USSRC's Space Hall.
However, it was eventually moved outdoors sometime before my first visit in
July 2002 to make room for other exhibits.
The Orbital Workshop portion of the trainer was restored and moved
into the Davidson Center in time for the USSRC's Skylab 40th anniversary
commemoration in 2013.
Here we see, from left to right, the Multiple
Docking Adapter/Airlock Module, the Fixed
Airlock Shroud (short, black cylinder just barely peeking out), the lower
part of the Orbital Workshop, the Apollo
Telescope Mount, and upper part of the Orbital Workshop.
