The NASA logo illuminated on the side of the Michoud Assembly Facility in New Orleans, Louisiana. Established during World War II and later repurposed for the Apollo and Space Shuttle programs, the vast complex continues to play a central role in U.S. space manufacturing. Today, Michoud supports construction of major components for NASA’s Artemis missions, including the Space Launch System rocket and Orion spacecraft.

The forward skirt section of NASA’s Space Launch System is shown shortly after its final assembly at the Michoud Assembly Facility in New Orleans. This uppermost segment houses the rocket’s flight computers, avionics, and camera systems, forming the control center that guides the SLS during launch and ascent. Built for Artemis I (Exploration Mission-1), this structure would later be integrated into the core stage for its 2020 launch from Kennedy Space Center.

Inside NASA’s Michoud Assembly Facility in New Orleans, an advanced robotic welding system—developed by Genesis Systems Group and Boeing—assembles major components for the Space Launch System (SLS) core stage. Using friction stir welding, the robot precisely joins massive aluminum panels into the rocket’s fuel tanks and structural sections. The process ensures unmatched strength and reliability, critical for the launch vehicle that powers NASA’s Artemis missions to the Moon and beyond.

Precision barrel tooling used in the assembly of the Space Launch System (SLS) core stage stands on the production floor at NASA’s Michoud Assembly Facility in New Orleans. These fixtures hold massive aluminum panels in place during the friction stir welding process, ensuring perfect alignment and uniform curvature for the rocket’s cylindrical sections. Behind the tooling, the metallic structure of a completed barrel segment can be seen, ready for the next stage of integration.
