Space Launch System Corestage-1 (Artemis-1) in production at the Michoud Assembly Faclility in New Orleans.

This image highlights the liquid oxygen tank, which will be used on the core stage of NASA’ Space Launch System rocket for Artemis II, the first crewed mission of NASA’s Artemis program, at NASA’s Michoud Assembly Facility. The SLS core stage is made up of five unique elements: the forward skirt, liquid oxygen tank, intertank, liquid hydrogen tank, and the engine section. The forward skirt houses flight computers, cameras, and avionics systems. The liquid oxygen tank holds 196,000 gallons of liquid oxygen cooled to minus 297 degrees Fahrenheit. The LOX hardware sits between the core stage’s forward skirt and the intertank. Along with the liquid hydrogen tank, it will provide fuel to the four RS-25 engines at the bottom of the core stage to produce more than two million pounds of thrust to launch NASA’s Artemis missions to the Moon. Together with its four RS-25 engines, the rocket’s massive 212-foot-tall core stage — the largest stage NASA has ever built — and its twin solid rocket boosters will produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit to the Moon and, ultimately, Mars. Offering more payload mass, volume capability and energy to speed missions through space, the SLS rocket, along with NASA’s Gateway in lunar orbit, the Human Landing System, and Orion spacecraft, is part of NASA’s backbone for deep space exploration and the Artemis lunar program. No other rocket can send astronauts in Orion around the Moon in a single mission.

Teams move a liquid hydrogen tank for NASA’s SLS (Space Launch System) rocket out of a priming cell and into an adjacent cell on May 20 at the agency’s Michoud Assembly Facility in New Orleans. Inside the cell, the tank, which will be used on the core stage of NASA’s Artemis III mission, will receive its thermal protection system. The thermal protection system, or spray-on foam insulation, provides protection to the core stage during launch. It is flexible enough to move with the rocket yet can withstand the aerodynamic pressures as the SLS accelerates from 0 to 17,500 mph and soars to more than 100 miles above the Earth. This third-generation insulation is more environmentally friendly and keeps the cryogenic propellant, which powers the rocket’s four RS-25 engines, extremely cold (the liquid hydrogen must remain at minus 423 degrees Fahrenheit/253 degrees Celsius) to remain in its liquid state. When applied the thermal protection system is a light-yellow color, which “tans” once exposed to the Sun’s ultraviolet rays, giving the SLS core stage its signature orange color.

These photos show teams at NASA’s Michoud Assembly Facility in New Orleans preparing, moving, and loading the engine section boat-tail of NASA’s SLS (Space Launch System) rocket for the Artemis III mission for transportation to NASA’s Kennedy Space Center in Florida via the agency’s Pegasus barge. Inside the factory on Aug. 14 prior to the move, technicians covered the spaceflight hardware with a tarp to help protect it on its journey aboard NASA’s Pegasus barge. Crews then rolled out the hardware on Aug. 27 from the factory floor to the barge. Once in Florida, the boat-tail will be integrated with the engine section -- also manufactured at Michoud -- inside Kennedy’s Space Station Processing Facility. The engine section arrived at NASA Kennedy in Dec. 2022. Located at the bottom of the engine section, the aerodynamic boat-tail fairing channels airflow and protects the stage’s four RS-25 engines from extreme temperatures during launch. The engine section is one of five major elements that make up the 212-foot-tall rocket stage.

Teams at NASA’s Michoud Assembly Facility in New Orleans move a liquid oxygen tank for its SLS (Space Launch System) rocket to a cleaning cell inside the facility’s vertical assembly building on Oct. 11. The tank, which will be used on the core stage of the agency’s Artemis III mission, will undergo an internal cleaning before moving on to its next phase of production. Inside the cleaning cell, a solution is sprayed into the tank to remove particulates which may collect during the manufacturing process. Once a tank is cleaned, teams use mobile clean rooms for internal access to the tank to prevent external contaminates from entering the hardware. The propellant tank is one of five major elements that make up the 212-foot-tall rocket stage.

The tank, which will be used on the core stage of the agency’s SLS (Space Launch System) rocket for its Artemis III mission, will undergo an internal cleaning before moving on to its next phase of production. Inside the cleaning cell, a solution is sprayed into the tank to remove particulates which may collect during the manufacturing process. Once a tank is cleaned, teams use mobile clean rooms for internal access to the tank to prevent external contaminates from entering the hardware. The propellant tank is one of five major elements that make up the 212-foot-tall rocket stage. The core stage, along with its four RS-25 engines, produce more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis.

These photos and videos show teams at NASA’s Michoud Assembly Facility in New Orleans preparing, moving, and loading the engine section of a future SLS (Space Launch System) rocket to NASA’s Pegasus barge Aug. 28. The hardware will form the bottom-most section of the SLS core stage that will power NASA’s Artemis IV mission, which will be the first mission to the Gateway space station in lunar orbit under the Artemis campaign. The barge will transport the spaceflight hardware to NASA’s Kennedy Space Center in Florida via the agency’s Pegasus barge. Once in Florida, the engine section will undergo final outfitting inside Kennedy’s Space Station Processing Facility.

This image highlights the liquid oxygen tank, which will be used on the core stage of NASA’ Space Launch System rocket for Artemis II, the first crewed mission of NASA’s Artemis program, at NASA’s Michoud Assembly Facility. The SLS core stage is made up of five unique elements: the forward skirt, liquid oxygen tank, intertank, liquid hydrogen tank, and the engine section. The forward skirt houses flight computers, cameras, and avionics systems. The liquid oxygen tank holds 196,000 gallons of liquid oxygen cooled to minus 297 degrees Fahrenheit. The LOX hardware sits between the core stage’s forward skirt and the intertank. Along with the liquid hydrogen tank, it will provide fuel to the four RS-25 engines at the bottom of the core stage to produce more than two million pounds of thrust to launch NASA’s Artemis missions to the Moon. Together with its four RS-25 engines, the rocket’s massive 212-foot-tall core stage — the largest stage NASA has ever built — and its twin solid rocket boosters will produce 8.8 million pounds of thrust to send NASA’s Orion spacecraft, astronauts and supplies beyond Earth’s orbit to the Moon and, ultimately, Mars. Offering more payload mass, volume capability and energy to speed missions through space, the SLS rocket, along with NASA’s Gateway in lunar orbit, the Human Landing System, and Orion spacecraft, is part of NASA’s backbone for deep space exploration and the Artemis lunar program. No other rocket can send astronauts in Orion around the Moon in a single mission.

Teams at NASA’s Michoud Assembly Facility in New Orleans successfully completed hydrostatic proof testing of the core stage liquid oxygen tank for the agency’s Artemis III mission. The non-destructive evaluation method tests the structural integrity of the tank’s welds by filling the tank with water, simulating the propellant used during launch. The hardware was then moved to an adjacent cell for internal cleaning. Next, the tank will be readied for primer and application of its thermal protection system. The propellant tank is one of five major elements that make up the 212-foot-tall rocket stage. The core stage, along with its four RS-25 engines, produce two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis.

Teams move a liquid hydrogen tank for NASA’s SLS (Space Launch System) rocket out of a priming cell and into an adjacent cell on May 20 at the agency’s Michoud Assembly Facility in New Orleans. Inside the cell, the tank, which will be used on the core stage of NASA’s Artemis III mission, will receive its thermal protection system. The thermal protection system, or spray-on foam insulation, provides protection to the core stage during launch. It is flexible enough to move with the rocket yet can withstand the aerodynamic pressures as the SLS accelerates from 0 to 17,500 mph and soars to more than 100 miles above the Earth. This third-generation insulation is more environmentally friendly and keeps the cryogenic propellant, which powers the rocket’s four RS-25 engines, extremely cold (the liquid hydrogen must remain at minus 423 degrees Fahrenheit/253 degrees Celsius) to remain in its liquid state. When applied the thermal protection system is a light-yellow color, which “tans” once exposed to the Sun’s ultraviolet rays, giving the SLS core stage its signature orange color.
