The Orbital Maneuvering Vehicle (OMV) systems' performance coupled with its canti-levered payload capability provides an excellent orbital test bed for short- and intermediate-duration life support subsystem and subscale system experimental investigations. As an experiment carrier or support vehicle, the OMV can remove the experiment or engineering test bed from the National Space Transportation System (NSTS) or Space Station environmental influences. This paper explores both the primary OMV capability to support short-term experiments as well as intermediate-duration evaluations of life support system.
