At NASA’s Michoud Assembly Facility in New Orleans, technicians from Orion prime contractor Lockheed Martin have welded together three cone-shaped panels on Orion’s crew module for the Artemis III mission that will land the first woman and next man on the Moon. The crew module’s primary structure, the pressure vessel, is comprised of seven machined aluminum alloy pieces that are welded together through a weld process that produces a strong, air-tight habitable space for astronauts during the mission. The pressure vessel is designed to withstand the harsh and demanding environment of deep space, and is the core structure upon which all the other elements of Orion’s crew module are integrated. Infographic showing the seven pieces of Orion's underlying structure With welding complete on the crew module cone panels – one of which contains windows providing astronauts views of the Moon and Earth – work will begin joining the forward bulkhead to the tunnel to create the top of the spacecraft, followed by the barrel and aft bulkhead join to form the bottom of Orion. Last, the forward bulkhead will be welded to the top of the panels and, for the seventh and closeout weld, the bottom of the cone panels will be joined to the barrel to complete the pressure vessel. Once welding of the Artemis III crew module primary structure is complete, it will be shipped to NASA’s Kennedy Space Center in Florida where it will undergo further assembly beginning this fall. Orion, the Space Launch System, and Exploration Ground Systems programs are foundational elements of the Artemis program. Artemis I will be the first integrated flight test of Orion and SLS and is targeted to launch later this year. Artemis II will follow and is the first crewed mission, taking humans farther into space than ever before. Image credit: NASA/Michael DeMocker

NASA Flips Artemis II Engine Section, Prepares for Final Join
NASA has completed assembly of the upper, or forward, part of the core stage for the Space Launch System (SLS) rocket that will send the Artemis II crew on their lunar mission. Boeing, the lead core stage contractor, completed joining the forward part of the rocket, and then lifted it out of the assembly structure at NASA’s Michoud Assembly Facility in New Orleans. To construct this part of the core stage, the team first stacked three major parts of the stage—the forward skirt, the liquid oxygen tank, and the intertank. The forward skirt sits atop the rocket’s core stage, and it and the intertank are outfitted with the rocket’s flight computers and avionics systems that control SLS during launch and ascent. The liquid oxygen tank holds 196,000 gallons of liquid oxygen cooled to minus 297 degrees Fahrenheit. The entire upper part of the stage is around 66-feet tall. The fully-assembled, 212-foot-tall rocket stage consists of five hardware elements. As the team lifted it out of the assembly area, they completed a breakover maneuver, to put the forward assembly in a horizontal position. Then, they moved it to final assembly where the Artemis II liquid hydrogen tank is also undergoing outfitting. Here, teams will connect the liquid hydrogen tank to the upper part of the rocket and complete assembly of four of the five core stage parts. The last piece to be added will be the engine section, which is currently in a separate assembly area being outfitted with propulsion systems that connect to the engines.

At NASA’s Michoud Assembly Facility in New Orleans, technicians from Orion prime contractor Lockheed Martin have welded together three cone-shaped panels on Orion’s crew module for the Artemis III mission that will land the first woman and next man on the Moon. The crew module’s primary structure, the pressure vessel, is comprised of seven machined aluminum alloy pieces that are welded together through a weld process that produces a strong, air-tight habitable space for astronauts during the mission. The pressure vessel is designed to withstand the harsh and demanding environment of deep space, and is the core structure upon which all the other elements of Orion’s crew module are integrated. Infographic showing the seven pieces of Orion's underlying structure With welding complete on the crew module cone panels – one of which contains windows providing astronauts views of the Moon and Earth – work will begin joining the forward bulkhead to the tunnel to create the top of the spacecraft, followed by the barrel and aft bulkhead join to form the bottom of Orion. Last, the forward bulkhead will be welded to the top of the panels and, for the seventh and closeout weld, the bottom of the cone panels will be joined to the barrel to complete the pressure vessel. Once welding of the Artemis III crew module primary structure is complete, it will be shipped to NASA’s Kennedy Space Center in Florida where it will undergo further assembly beginning this fall. Orion, the Space Launch System, and Exploration Ground Systems programs are foundational elements of the Artemis program. Artemis I will be the first integrated flight test of Orion and SLS and is targeted to launch later this year. Artemis II will follow and is the first crewed mission, taking humans farther into space than ever before. Image credit: NASA/Michael DeMocker
Welding Underway on Orion for First Artemis Mission Landing Astronauts on the Moon
Technician’s at NASA’s Michoud Assembly Facility in New Orleans prepared the newly-welded Artemis III mission Orion pressure vessel for shipment to NASA’s Kennedy Space Center’s in Florida, where it later arrived on October 15 at Kennedy’s Neil A. Armstrong Operations and Checkout Building. The pressure vessel, which was joined together using state-of-the-art welding by technicians from lead contractor Lockheed Martin, is the Orion crew module primary structure – the core upon which all other elements of Orion’s crew module are integrated. The structure is a critical element for crew as it holds the pressurized atmosphere astronauts breathe and work in while in the vacuum of deep space. Once transported to Kennedy’s Vehicle Assembly Building high bay, teams will begin integration of the pressure vessel with the Orion spacecraft crew module adapter and other assembly.

NASA’s Space Launch System (SLS) team fully stacked three hardware elements together May 24 to form the top of the rocket’s core stage for the Artemis II mission. NASA and core stage prime contractor Boeing connected the forward skirt with the liquid oxygen tank and intertank flight hardware inside an assembly area at NASA’s Michoud Assembly Facility in New Orleans. Teams had previously stacked the liquid oxygen tank and intertank on April 28. The joining of the three structures together is the first major assembly of core stage hardware for Artemis II, the first crewed Artemis mission and second flight of the SLS rocket. Next, technicians will work to complete outfitting and integrating the systems within the upper structure. At 66 feet tall, the upper part of the stage is just a fraction of the entire core stage. The fully-assembled, 212-foot-tall rocket stage consists of five hardware elements, including two liquid propellant tanks and four RS-25 engines. The liquid oxygen tank in the upper portion of the stage will hold 196,000 gallons of liquid oxygen cooled to minus 297 degrees Fahrenheit. Meanwhile, the forward skirt and intertank house avionics, flight computer, and electronic systems for the rocket stage. Together, the core stage and its four RS-25 engines will provide more than 2 million pounds of thrust to help send Artemis II astronauts beyond Earth’s orbit to lunar orbit. With Artemis, NASA will land the first woman and the first person of color on the Moon and establish sustainable exploration in preparation for missions to Mars. SLS and NASA’s Orion spacecraft, along with the commercial human landing system and the Gateway in orbit around the Moon, are NASA’s backbone for deep space exploration.

EUS panel test weld at the VXC in Building 115 at the Michoud Assembly Facility on Tuesday, February 9, 2021. Technicians are manufacturing and testing the first in a series of initial weld confidence articles for the Exploration Upper Stage (EUS) for future flights of NASA’s Space Launch System (SLS) rocket at the agency’s Michoud Assembly Facility in New Orleans. The Exploration Upper Stage will be used on the second configuration of the SLS rocket, known as Block 1B, and will provide in-space propulsion to send astronauts in NASA’s Orion spacecraft and heavy cargo on a precise trajectory to the Moon. The Exploration Upper Stage weld confidence panels are first produced in the Vertical Weld Center at Michoud, then small sections of the panels are removed for mechanical testing and analysis in another area of the factory. Teams use weld confidence articles to verify welding procedures, interfaces between the tooling and hardware, and the structural integrity of the welds. Testing of the EUS weld confidence articles will help engineers and technicians validate welding parameters for manufacturing EUS hardware. The first three SLS flights of NASA’s Artemis program will use an interim cryogenic propulsion stage with one RL10 engine to send Orion to the Moon. The SLS Exploration Upper Stage for flights beyond Artemis III has larger propellant tanks and four RL10 engines. The evolution of the rocket to SLS Block 1B configuration with EUS enables SLS to launch 40% more cargo to the Moon along with the crew. Manufacturing the Exploration Upper Stage is a collaborative effort between NASA and Boeing, the lead contractor for EUS and the SLS core stage. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission. The SLS rocket, NASA’s Orion spacecraft, Gateway, and human landing system are part of NASA’s backbone for deep space exploration. Under the Artemis program, NASA is working to land the first woman and the next man on the Moon to pave the way for sustainable exploration at the Moon and future missions to Mars. (NASA)

NASA joined the Space Launch System rocket’s core stage forward assembly with the 130-foot liquid hydrogen tank for the Artemis II mission on March 18. This completes assembly of four of the five large structures that make up the core stage that will help send the first astronauts to lunar orbit on Artemis II. The 66-foot forward assembly consists of the forward skirt, liquid oxygen tank and the intertank, which were mated earlier. Engineers inserted 360 bolts to connect the forward assembly to the liquid hydrogen tank to make up the bulk of the stage. Only the engine section, which is currently being outfitted and includes the main propulsion systems that connect to the four RS-25 engines, remains to be added to form the final core stage. All parts of the core stage are manufactured by NASA and Boeing, the core stage lead contractor at the agency’s Michoud Assembly Facility in New Orleans. Currently, the team is building core stages for three Artemis missions. The first core stage is stacked with the rest of the SLS rocket, which will launch the Artemis I mission to the Moon this year. Together with its 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 Artemis missions and future deep space exploration. Image credit: NASA/Michael DeMocker
NASA Joins Four Major SLS Rocket Parts to Form Artemis II Core Stage
Technicians at NASA’s Michoud Assembly Facility prepare to move the engine section of NASA’s Space Launch System rocket for Artemis IV to the Vertical Assembly Building for the next step in production. This hardware is the first large piece manufactured for the Artemis IV mission and makes up the lowest portion of the 212-foot-tall core stage. When complete, the engine section will house the four RS-25 engines and include vital systems for mounting, controlling and delivering fuel from the propellant tanks to the rocket’s engines. Together with its four RS-25 engines and its twin solid rocket boosters, it 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 is capable of carrying astronauts in Orion around the Moon in a single mission. Photographed on Thursday, May 12, 2022. Image credit: NASA/Michael DeMocker

NASA Makes Progress on Artemis II Core Stage Assembly
At NASA’s Michoud Assembly Facility in New Orleans, technicians from Orion prime contractor Lockheed Martin have welded together three cone-shaped panels on Orion’s crew module for the Artemis III mission that will land the first woman and next man on the Moon. The crew module’s primary structure, the pressure vessel, is comprised of seven machined aluminum alloy pieces that are welded together through a weld process that produces a strong, air-tight habitable space for astronauts during the mission. The pressure vessel is designed to withstand the harsh and demanding environment of deep space, and is the core structure upon which all the other elements of Orion’s crew module are integrated. Infographic showing the seven pieces of Orion's underlying structure With welding complete on the crew module cone panels – one of which contains windows providing astronauts views of the Moon and Earth – work will begin joining the forward bulkhead to the tunnel to create the top of the spacecraft, followed by the barrel and aft bulkhead join to form the bottom of Orion. Last, the forward bulkhead will be welded to the top of the panels and, for the seventh and closeout weld, the bottom of the cone panels will be joined to the barrel to complete the pressure vessel. Once welding of the Artemis III crew module primary structure is complete, it will be shipped to NASA’s Kennedy Space Center in Florida where it will undergo further assembly beginning this fall. Orion, the Space Launch System, and Exploration Ground Systems programs are foundational elements of the Artemis program. Artemis I will be the first integrated flight test of Orion and SLS and is targeted to launch later this year. Artemis II will follow and is the first crewed mission, taking humans farther into space than ever before. Image credit: NASA/Michael DeMocker

The LOX tank holds 196,000 gallons of super-cooled liquid oxygen to help fuel four RS-25 engines. 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 liquid oxygen hardware, along with the liquid hydrogen tank will provide propellant to the four RS-25 engines to produce more than two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit 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 is capable of carrying astronauts in Orion around the Moon in a single mission. Photographed on Tuesday, May 10, 2022. Image credit: NASA/Michael DeMocker

NASA Readies Artemis II Liquid Hydrogen Tank for Next Phase of Manufacturing
These photos show how teams moved and prepared a liquid hydrogen tank for the SLS (Space Launch System) rocket for priming in the Vertical Assembly Building at NASA’s Michoud Assembly Facility in New Orleans Nov. 14, 2023. The hardware will form part of the core stage for the SLS rocket that will power Artemis III. To prepare the flight hardware for primer, the tank underwent internal cleaning in nearby Cell E in October. Internal cleaning is part of the manufacturing process for the core stage. After testing, both of the stage’s propellant tanks and its dry structures – the elements that do not hold fuel – are cleaned, primed, and readied for the next phase of production Technichians will next sand down and prepare the surface of the tank before coating it in a primer. Primer is applied to the barrel section of the tank by an automated robotic tool, whereas the forward and aft domes are primed manually. The propellant tank is the largest of the five major elements that make up the 212-foot-tall Moon 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.

NASA Rocket Liquid Hydrogen Tank Moved for Priming
NASA rolled out a key piece of space flight hardware for the SLS (Space Launch System) rocket for the first crewed mission of NASA’s Artemis campaign from Marshall Space Flight Center in Huntsville, Alabama, on Wednesday, Aug. 21 for shipment to the agency’s spaceport in Florida. The cone-shaped launch vehicle stage adapter connects the rocket’s core stage to the upper stage and helps protect the upper stage’s engine that will help propel the Artemis II test flight around the Moon, slated for 2025. Manufactured by prime contractor Teledyne Brown Engineering and the Jacobs Space Exploration Group’s ESSCA (Engineering Services and Science Capability Augmentation) contract using NASA Marshall’s self-reacting friction-stir robotic and vertical weld tools. Crews moved the adapter out of NASA Marshall’s Building 4708 to the agency’s Pegasus barge Aug. 21. The barge will ferry the adapter first to NASA’s Michoud Assembly Facility in New Orleans, where crews will pick up additional SLS hardware for future Artemis missions, before traveling to NASA Kennedy. Once in Florida, the adapter will join the recently delivered core stage. There, teams with NASA’s Exploration Ground Systems will prepare the adapter for stacking and launch.
