BUILDING THE TOOLS TO BUILD THE NEXT SPACECRAFT

Caption and Image Credit:  NASA.  World's Largest Spacecraft Welding Tool for Space Launch System-The largest spacecraft welding tool in the world, the Vertical Assembly Center, officially is open for business at NASA's Michoud Assembly Facility in New Orleans. 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 RS-25 engines.

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.
