               Introducing NASA's New Spaceship 
                 
                
                 
                 
                NASA's new spaceship is the key to making the Vision for Space 
                Exploration a reality. The Vision, announced by President Bush 
                in January 2004, will extend humanity's presence across the solar 
                system, starting with a return to the moon by the end of the next 
                decade, followed by journeys to Mars and beyond.  
                 
                Building on the best of Apollo and shuttle technology, NASA's 
                21st century exploration system will be affordable, reliable, 
                versatile and safe. The centerpiece of this system is a new craft 
                designed to carry four astronauts to and from the moon, support 
                up to six crew members on future missions to Mars, and deliver 
                crew and cargo to the international space station.  
                 
                Mockup Provides Early Glimpse of New Exploration Vehicle 
                 
                 
                As NASA's next generation spacecraft matures, engineers will document 
                its design with today's electronic equivalent to the blueprint. 
                But diagrams, three-dimensional or not, only go so far in helping 
                engineers understand what layouts best suit the job at hand and 
                the humans involved.  
                 
                That's why Johnson Space Center in Houston has started building 
                a full-sized mockup of the new craft's cockpit in its Space Vehicle 
                Mockup Facility.  
                 
                The new spaceship -- known as the Crew Exploration Vehicle -- 
                is the key to making NASA's Vision for Space Exploration a reality. 
                A quick glance at the mockup reveals the resemblance to the original 
                Apollo crew capsule. But the new capsule will be three times larger 
                and is designed to carry four astronauts to and from the Moon, 
                support up to six crew members on future missions to Mars and 
                deliver crew and supplies to the International Space Station. 
                 
                 
                Inside, the mockup remains largely unfinished. A temporary floor 
                foreshadows the location for launch and entry seating, and a large 
                hatch dominates the top of the cone. The hatch is wide enough 
                for a human to pass through easily and will be the point where 
                the crew capsule will dock with a lunar lander for the first trip 
                back to the Moon, currently targeted for 2018.  
                 
                The mockup represents the first leg of a three-step design philosophy. 
                In stage one, design teams discuss various theories over how best 
                to utilize cockpit space and commit their ideas to paper. Then 
                engineers use computer design programs to produce working 3-D 
                models of the crew’s space. While work continues on these stages, 
                team members simultaneously use the mockup to experiment with 
                physical relationships in a real-world environment.  
                 
                "You discover new things during each stage of the design process," 
                said Jeff Fox, lead cockpit engineer on the spacecraft. "But your 
                brain needs the input of physically standing inside the real volume 
                of the interior space to get a true feeling of what should be 
                the right layout."  
                 
                Workers are making changes to ensure the current model matches 
                the inner measurements of the most recent design. Once that's 
                finished, the team will start working on how to arrange seats 
                and where to put the spacecraft's controls.  
                 
                The team is already working on plans to arrange cockpit seating 
                in three-, four- and six-person configurations. In the early phases, 
                simple foam-core boxes will serve as substitutes for real-world 
                hardware such as computers and cargo.  
                 
                The stand-ins will gradually give way to more accurate versions 
                of the real thing, helping the designers visualize what the computers 
                can't show. As Fox puts it, "there’s just no substitute for reality."
