Teams at NASA’s Michoud Assembly Facility in New Orleans move a liquid hydrogen tank for the agency’s SLS (Space Launch System) rocket into the factory’s final assembly area on April 22. Having recently completed application of the thermal protection system, teams will now continue outfitting the 130-foot-tall tank with critical systems to ready it for its designated Artemis III mission. 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.
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 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.

Teams at NASA’s Michoud Assembly Facility in New Orleans move the engine section flight hardware to the agency’s Pegasus barge Sunday, Dec. 4. The barge will ferry the engine section of NASA’s Space Launch System (SLS) rocket for Artemis III to the agency’s Kennedy Space Center in Florida. Once there, teams at Kennedy will finish outfitting the engine section, which comprises the tail-end of the rocket’s 212-foot-tall core stage, before integrating it to the rest of the stage. Beginning with production for Artemis III, NASA and core stage lead contractor Boeing will use Michoud, where the SLS core stages are currently manufactured, to produce and outfit the core stage’s five elements, and available space at Kennedy for final assembly and integration.

Move crews at NASA’s Michoud Assembly Facility in New Orleans perform “breakover” operations on a liquid oxygen tank in the facility’s vertical assembly building on Aug. 22, 2025. During the breakover, teams lifted the tank from its vertical configuration inside of a production cell and set it horizontally atop self-propelled mobile transporters for transfer to the final assembly production area. There, it will undergo integration of the forward dome by SLS (Space Launch System) prime contractor, Boeing. Eventually, the liquid oxygen tank will be moved back to the high bay where it will be mated with the intertank and forward skirt to complete the forward join of the Artemis III core stage.

These images/video show how teams rolled out, or moved, the completed core stage for NASA’s Space Launch System rocket from NASA’s Michoud Assembly Facility in New Orleans. Crews moved the flight hardware for the first Artemis mission to NASA’s Pegasus barge on Jan. 8 in preparation for the core stage Green Run test series at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Pegasus, which was modified to ferry SLS rocket hardware, will transport the core stage from Michoud to Stennis for the comprehensive core stage Green Run test series. Once at Stennis, the Artemis rocket stage will be loaded into the B-2 Test Stand for the core stage Green Run test series. The comprehensive test campaign will progressively bring the entire core stage, including its avionics and engines, to life for the first time to verify the stage is fit for flight ahead of the launch of Artemis I. Assembly and integration of the core stage and its four RS-25 engines has been a collaborative, multistep process for NASA and its partners Boeing, the core stage lead contractor, and Aerojet Rocketdyne, the RS-25 engines lead contractor. Together with 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 and Orion, is part of NASA’s backbone for deep space exploration and the Artemis lunar program.

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 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.

These images/video show how teams rolled out, or moved, the completed core stage for NASA’s Space Launch System rocket from NASA’s Michoud Assembly Facility in New Orleans. Crews moved the flight hardware for the first Artemis mission to NASA’s Pegasus barge on Jan. 8 in preparation for the core stage Green Run test series at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Pegasus, which was modified to ferry SLS rocket hardware, will transport the core stage from Michoud to Stennis for the comprehensive core stage Green Run test series. Once at Stennis, the Artemis rocket stage will be loaded into the B-2 Test Stand for the core stage Green Run test series. The comprehensive test campaign will progressively bring the entire core stage, including its avionics and engines, to life for the first time to verify the stage is fit for flight ahead of the launch of Artemis I. Assembly and integration of the core stage and its four RS-25 engines has been a collaborative, multistep process for NASA and its partners Boeing, the core stage lead contractor, and Aerojet Rocketdyne, the RS-25 engines lead contractor. Together with 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 and Orion, is part of NASA’s backbone for deep space exploration and the Artemis lunar program.
Teams at NASA’s Michoud Assembly Facility in New Orleans move a liquid hydrogen tank for the agency’s SLS (Space Launch System) rocket into the factory’s final assembly area on April 22. Having recently completed application of the thermal protection system, teams will now continue outfitting the 130-foot-tall tank with critical systems to ready it for its designated Artemis III mission. 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 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. 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.

Beginning with production for Artemis III, NASA and core stage lead contractor Boeing will use Michoud, where the SLS core stages are currently manufactured, to produce and outfit the core stage’s five elements, and available space at Kennedy for final assembly and integration.
