The 170-foot-tall, 78-foot-wide giant completes a world-class welding toolkit that will be used to build the core stage of America's next great rocket, the Space Launch System (SLS). SLS will be the most powerful rocket ever built for deep space missions, including to an asteroid and eventually Mars. The core stage, towering more than 200 feet tall (61 meters) with a diameter of 27.6 feet (8.4 meters), will store cryogenic liquid hydrogen and liquid oxygen that will feed the rocket's four RS-25 engines. <center><a href="http://www.collectspace.com/review/sls_verticalassemblycenter01-lg.jpg" target="AirLock"><img src="http://www.collectspace.com/review/sls_verticalassemblycenter01.jpg" width="400" height="603" border="0"></a></center> [i][b]Above[/b]: A 16mm fisheye lens was used to show a wide angle view of the Vertical Assembly Center at NASA’s Michoud Assembly Facility in New Orleans at a ribbon-cutting ceremony Sept 12.[/i] (NASA) "This rocket is a game changer in terms of deep space exploration and will launch NASA astronauts to investigate asteroids and explore the surface of Mars while opening new possibilities for science missions, as well," said NASA Administrator Charles Bolden during a ribbon-cutting ceremony at Michoud Friday. The Vertical Assembly Center is part of a family of state-of-the-art tools designed to weld the core stage of SLS. It will join domes, rings and barrels to complete the tanks or dry structure assemblies. It also will be used to perform evaluations on the completed welds. Boeing is the prime contractor for the SLS core stage, including avionics. "The SLS Program continues to make significant progress," said Todd May, SLS program manager. "The core stage and boosters have both completed critical design review, and NASA recently approved the SLS Program's progression from formulation to development. This is a major milestone for the program and proof the first new design for SLS is mature enough for production." Work is well underway on several additional welding tools. Engineers recently completed welding all the rings for the first flight of SLS using the Segmented Ring Tool. Ten barrels also have been welded for the SLS core stage using the Vertical Weld Center. The rings connect and provide stiffness between domes and barrels, which will make-up the five major core stage structures: the forward skirt, the liquid oxygen tank, the intertank, the liquid hydrogen tank and the engine section.</BLOCKQUOTE> <a name="090915a"></a>[/B][/QUOTE]
