The Vertical Assembly Center rises inside the Michoud Assembly Facility, where major sections of NASA’s Space Launch System core stage are stacked and integrated. This multi-story structure supports the alignment and joining of large rocket elements, including propellant tanks and structural segments, into a single flight article. Built at Michoud and later transported for testing and launch, each core stage reflects the continuation of large-scale rocket manufacturing at a facility that has supported U.S. human spaceflight since the Saturn V program.
