Mockup Development Facility

    The Mockup Development Facility is utilized to develop low-to-medium fidelity full-scale mockups of space vehicles and habitats.  Mockups developed to date include a horizontal axis cylindrical habitat module, a toroidal habitat module, a lander translation tunnel test article, a descent stage mockup (partially complete), and—most recently—a vertical axis cylindrical habitat demonstration test article.  Testing of these mockups can be performed in place at the Building 220 facility or can, in some cases, be performed at analog field test sites or in reduced-gravity aircraft.
