Technicians at NASA’s Michoud Assembly Facility in New Orleans completed the “forward join,” which connects structures to form the top part of NASA’s Space Launch System (SLS) rocket’s core stage. The first core stage will send Exploration Mission-1, the first integrated flight of SLS and NASA’s Orion spacecraft, out beyond the Moon. The forward join mated three structures: the forward skirt, liquid oxygen tank and intertank. This milestone marks the beginning of integration and assembly of the massive, 212-foot-tall SLS core stage, which will include the rocket’s four RS-25 rocket engines, propellant tanks and flight computers. Now, NASA and Boeing, the SLS prime contractor, will continue to integrate various systems inside the forward part of the core stage and prepare for structural joining of the liquid hydrogen tank and engine section to form the bottom of the stage. These two parts of the core stage will then be assembled to form the largest stage NASA has ever built.

NASA is preparing major pieces of the Space Launch System rocket’s core stage to be joined as part of assembling the core stage for the Artemis II mission that will send crews to lunar orbit. Crews will soon connect the forward assembly with the 130-foot liquid hydrogen tank in the final assembly area at NASA’s Michoud Assembly Facility in New Orleans. When this process is completed, four of the five large structures that make up the core stage will be joined. The 66-foot forward assembly consists of the forward skirt, liquid oxygen tank and the intertank, which were mated earlier. This forward assembly will be joined with the 130-foot liquid hydrogen tank, the largest part of the stage that holds more than 500,000 gallons of cryogenic propellant. To compete the Artemis II core stage, engineers will add the engine section, which is currently being outfitted and includes the main propulsion systems that connect to the four RS-25 engines, Together, with the SLS twin solid rocket boosters, the core stage will produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit to the Moon. The SLS rocket and the Orion spacecraft form the foundation for deep space exploration and the Artemis lunar program.

Crews at NASA’s Michoud Assembly Facility in New Orleans reinstalled the iconic NASA meatball logo to the side of the 43-acre factory following a months-long project to replace the corrugated asbestos paneling original to the building’s construction on the outer façade of the facility. The new paneling is an insulated metal sandwich panel, which provides an increased insulation R-value. The new fastening system can withstand significant wind loads, adding greater protection against hurricanes, tornados, and other storm-related events common to the area; and is critical to help protect vital hardware for the Space Launch System rockets and the Orion Spacecrafts manufactured at Michoud for NASA’s Artemis missions, which will land the first woman and first person of color on the moon.

Technicians at NASA’s Michoud Assembly Facility in New Orleans completed the “forward join,” which connects structures to form the top part of NASA’s Space Launch System (SLS) rocket’s core stage. The first core stage will send Exploration Mission-1, the first integrated flight of SLS and NASA’s Orion spacecraft, out beyond the Moon. The forward join mated three structures: the forward skirt, liquid oxygen tank and intertank. This milestone marks the beginning of integration and assembly of the massive, 212-foot-tall SLS core stage, which will include the rocket’s four RS-25 rocket engines, propellant tanks and flight computers. Now, NASA and Boeing, the SLS prime contractor, will continue to integrate various systems inside the forward part of the core stage and prepare for structural joining of the liquid hydrogen tank and engine section to form the bottom of the stage. These two parts of the core stage will then be assembled to form the largest stage NASA has ever built.
