Abstract: The present invention provides an improved integrated translation tube for the movement of equipment and personnel through space modules, particularly for non-rigid type space modules such as the NASA Transhab module. In addition, the present invention provides an internal framework for the structural support of the space module itself, and the equipment installed internally to the space module. The present invention's arched shaped translation tube provides sufficient strength and rigidity to provide the required structural support, while simultaneously maximizing the uninterrupted interior volume of the space module.
