dormitory building, and contains a restaurant and offices. Building 4 is located south of the complex. It is an industrial workshop for the processing and application of spray-on insulation foam to SLS tank components. Space Shuttle external tank spares were also housed there. Adjacent to the main manufacturing building are more foam application workshops, power transformers for the arc furnace and other facilities, and large amounts of open space. In front of the South VAB, rocket parts are moved from this building to the side internal workshops across the plaza for inspection and checks. The SLS core stage test simulator (made of steel) is also located in this area. The former National Finance Center (NSF) - located west of the complex; housed offices for the U.S. Department of Agriculture, and contained several large conference rooms, a restaurant and a ballroom for NASA employees and visitor events. The building was badly damaged by a tornado in 2017, which rendered the building irreparable. It was subsequently demolished in 2019 and a new replacement is yet to be built. The shipping port is located 600 meters southwest of the main manufacturing building. Transporting vehicles carrying manufactured SLS components move down Saturn Blvd, past large open fields, to the pier - where the Pegasus Barge is docked. This is where the components are shipped to either their final destination - Kennedy Space Center, or rarely back to the main Marshall Space Flight Center in Huntsville, Alabama, or the John C. Stennis Space Center in Mississippi for testing. Other and future activities The Michoud Assembly Facility also houses other organizations such as the National Finance Center operated by the United States Department of Agriculture, the United States Coast Guard, and GE. The factory complex is open to the public (though through pre-booking in advance). Visitors must sign in at main reception and clear security. NASA planned to use the rocket factory to build the structure for several components of the cancelled Constellation program, including the Orion spacecraft, the Ares I Upper Stage, and the Ares V Core Stage. Under the Obama administration, the Constellation Program was cancelled in 2010, but was replaced with SLS a year later to continue space exploration efforts. NASA has an agreement in place to rent out a portion of the facility to Big Easy Studios, a New Orleans film studio. This deal has been criticized by competing studios as violating
