In reality, the SpaceHab allows for the expansion of crew capability while in space.   It can be used for living quarters, experiments, transport, etc.   The modular design allows for it to be configured off site and installed into the shuttle just as any other payload would be.   This design may be typical for Orion/ CEV when that program matures.

 

WonderWorks built the first first ergonomic study module for SpaceHab many years ago.   Our Rental Spacehab Module shown on these pages was first built for the UK reality show Space Cadets.   Our rental splits in half lengthwise for ease of shipping and filming.   The two halves can be placed end to end thus increasing the visual length when shot from the side.
