On May 24, 2022, the core stage production team moved the Space Launch System (SLS) rocket engine section for Artemis II to the core stage final integration area at NASA’s Michoud Assembly Facility in New Orleans. While there, the engine section team is completing installation of the main propulsion systems, finishing integration of the electrical and avionics systems, and preparing for functional testing of the various systems. During final integration, the team also will install remaining internal thermal protection systems and prepare to position the engine section from vertical to horizontal so that it can be joined with the rest of the core stage. The engine section is located at the bottom of the core stage and includes the rocket’s main propulsion systems that connect to the core stage’s four RS-25 engines that will help launch the Artemis II lunar mission. This fall, the engine section will be horizontally integrated with the previously-joined forward assembly and liquid hydrogen tank to complete the core stage. NASA and core stage lead contractor Boeing are building core stages for the next three Artemis missions. The 212-foot core stage with its RS-25 engines will provide more than 2 million pounds of thrust at launch. With Artemis, NASA will land the first woman and the first person of color on the Moon and establish long-term 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. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

Technicians at NASA’s Michoud Assembly Facility in New Orleans moved the engine section of NASA’s Space Launch System (SLS) rocket for Artemis II, the first crewed mission to the Moon, into position for the final join of the core stage Feb. 22. The engine section is the bottom-most portion of the 212-foot-tall core stage. It is the last of five major elements that is needed to connect the stage into one major structure. In addition to its miles of cabling and hundreds of sensors, the engine section is a crucial attachment point for the four RS-25 engines and two solid rocket boosters that produce a combined 8.8 million pounds of thrust at liftoff and flight. During launch and flight, liquid propellants from the liquid hydrogen tank and liquid oxygen tanks are delivered through the engine section to the four RS-25 engines. The engine section also includes the avionics that help steer the engines after liftoff. Next, teams will join the engine section to the core stage for the second SLS rocket. After the join is complete, teams will begin to add each of the four RS-25 engines one by one to complete the stage. The completely assembled stage with its four RS-25 engines will be shipped to NASA’s Kennedy Space Center in Florida later this year. The SLS rocket is the only rocket capable of carrying astronauts in Orion around the Moon in a single mission.

Technicians transported the assembled upper part of the Artemis II core stage to the final assembly area inside the factory at NASA’s Michoud Assembly Facility in New Orleans. On Jan 10, the forward assembly, left was moved next to the Artemis II liquid hydrogen tank, which has been undergoing assembly. Next, Boeing, the lead core stage contractor, will join the forward assembly and the liquid hydrogen tank to complete most of the core stage for the Space Launch System (SLS) rocket that will send the first crew on an Artemis mission. The core stage consists of five major structures that are built, outfitted, and then connected to form the final stage. The forward skirt, liquid oxygen and intertank were connected and tested to form the 66-foot forward assembly. After the forward assembly is joined with the 130-foot liquid hydrogen tank, only the engine section, the fifth piece of the stage, will need to be added to complete the Artemis II core stage. The core stage serves as the backbone of the rocket, supporting the weight of the payload, upper stage, and crew vehicle, as well as the thrust of its four RS-25 engines and two five-segment solid rocket boosters attached to the engine and intertank sections. On Artemis II, the SLS rocket will launch the Orion spacecraft and a crew, sending them into lunar orbit, in preparation for later Artemis missions that will enable the first woman and first person of color to land on the Moon.

NASA finished assembling and joining the main structural components for the largest rocket stage the agency has built since the Saturn V that sent Apollo astronauts to the Moon. Engineers at the agency’s Michoud Assembly Facility in New Orleans connected the last of the five sections of the Space Launch System (SLS) rocket core stage Sept. 19. The stage will produce 2 million pounds of thrust to send Artemis I, the first flight SLS and NASA’s Orion spacecraft to the Moon. The engine section is located at the bottom of the 212-foot-tall stage and houses the four RS-25 engines. The core stage’s two liquid propellant tanks and four RS-25 engines will produce more than 2 million pounds of thrust to send the SLS rocket and Orion on the Artemis lunar missions. The engine section houses the four RS-25 engines and includes vital systems for mounting, controlling and delivering fuel form the propellant tanks to the rocket’s engines. 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. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission.

On Jan 10, the forward assembly, left was moved next to the Artemis II liquid hydrogen tank, which has been undergoing assembly. Next, Boeing, the lead core stage contractor, will join the forward assembly and the liquid hydrogen tank to complete most of the core stage for the Space Launch System (SLS) rocket that will send the first crew on an Artemis mission. The core stage consists of five major structures that are built, outfitted, and then connected to form the final stage. The forward skirt, liquid oxygen and intertank were connected and tested to form the 66-foot forward assembly. After the forward assembly is joined with the 130-foot liquid hydrogen tank, only the engine section, the fifth piece of the stage, will need to be added to complete the Artemis II core stage. The core stage serves as the backbone of the rocket, supporting the weight of the payload, upper stage, and crew vehicle, as well as the thrust of its four RS-25 engines and two five-segment solid rocket boosters attached to the engine and intertank sections. On Artemis II, the SLS rocket will launch the Orion spacecraft and a crew, sending them into lunar orbit, in preparation for later Artemis missions that will enable the first woman and first person of color to land on the Moon.

This image shows technicians and engineers moving the liquid oxygen tank (LOX) into position as they continue the process of the forward join on the core stage of NASA’s Space Launch System rocket for Artemis II, the first crewed mission of NASA’s Artemis program at NASA’s Michoud Assembly Facility. The forward join connects the forward skirt, the liquid oxygen tank (LOX) and the intertank structures to form the top part of the SLS rocket’s core stage. 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. 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. Image credit: NASA/Jared Lyons

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.

On May 24, 2022, the core stage production team moved the Space Launch System (SLS) rocket engine section for Artemis II to the core stage final integration area at NASA’s Michoud Assembly Facility in New Orleans. While there, the engine section team is completing installation of the main propulsion systems, finishing integration of the electrical and avionics systems, and preparing for functional testing of the various systems. During final integration, the team also will install remaining internal thermal protection systems and prepare to position the engine section from vertical to horizontal so that it can be joined with the rest of the core stage. The engine section is located at the bottom of the core stage and includes the rocket’s main propulsion systems that connect to the core stage’s four RS-25 engines that will help launch the Artemis II lunar mission. This fall, the engine section will be horizontally integrated with the previously-joined forward assembly and liquid hydrogen tank to complete the core stage. NASA and core stage lead contractor Boeing are building core stages for the next three Artemis missions. The 212-foot core stage with its RS-25 engines will provide more than 2 million pounds of thrust at launch. With Artemis, NASA will land the first woman and the first person of color on the Moon and establish long-term 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. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

The core stage liquid hydrogen tank for the Artemis III mission completed proof testing, and technicians returned it to the main factory building at NASA’s Michoud Assembly Facility in New Orleans where it will undergo more outfitting. As part of proof testing, technicians apply a simple soap solution and check for leaks by observing any bubble formation on the welds. The technician removed the bubble solution with distilled water and then dried the area of application to prevent corrosion. To build the Space Launch System (SLS) rocket’s 130-foot core stage liquid hydrogen tank, engineers use robotic tools to weld five-barrel segments. This process results in a tank with around 1,900 feet, or more than six football fields, of welds that must be tested by hand. After the leak tests, the core stage lead, Boeing, pressurized the SLS tank to further ensure there were no leaks. After it passed proof testing, technicians moved the Artemis III liquid hydrogen tank to Michoud’s main factory. Soon, the technicians will prime and apply a foam-based thermal protection system that protects the tank during launch. Later, the tank will be joined with other parts of the core stage to form the entire 212-foot rocket stage with its four RS-25 engines that produce 2 million pounds of thrust to help launch the rocket. Artemis III will land the first astronauts on the lunar surface.

These images 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.

Technicians at NASA’s Michoud Assembly Facility in New Orleans moved the engine section of NASA’s Space Launch System (SLS) rocket for Artemis II, the first crewed mission to the Moon, into position for the final join of the core stage Feb. 22. The engine section is the bottom-most portion of the 212-foot-tall core stage. It is the last of five major elements that is needed to connect the stage into one major structure. In addition to its miles of cabling and hundreds of sensors, the engine section is a crucial attachment point for the four RS-25 engines and two solid rocket boosters that produce a combined 8.8 million pounds of thrust at liftoff and flight. During launch and flight, liquid propellants from the liquid hydrogen tank and liquid oxygen tanks are delivered through the engine section to the four RS-25 engines. The engine section also includes the avionics that help steer the engines after liftoff. Next, teams will join the engine section to the core stage for the second SLS rocket. After the join is complete, teams will begin to add each of the four RS-25 engines one by one to complete the stage. The completely assembled stage with its four RS-25 engines will be shipped to NASA’s Kennedy Space Center in Florida later this year. The SLS rocket is the only rocket capable of carrying astronauts in Orion around the Moon in a single mission.

No other rocket can send astronauts in Orion around the Moon in a single mission.

This image highlights the liquid hydrogen tank that will be used on the core stage of NASA’s Space Launch System rocket for Artemis II, the first crewed mission of NASA’s Artemis program. The tank is being built at NASA’s Michoud Assembly Facility in New Orleans. 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 hydrogen tank holds 537,000 gallons of liquid hydrogen cooled to minus 423 degrees Fahrenheit and sits between the core stage’s intertank and engine section. The liquid hydrogen hardware, along with the liquid oxygen tank, will provide propellant to the four RS-25 engines at the bottom of the cores 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.

NASA finished assembling and joining the main structural components for the largest rocket stage the agency has built since the Saturn V that sent Apollo astronauts to the Moon. Engineers at the agency’s Michoud Assembly Facility in New Orleans connected the last of the five sections of the Space Launch System (SLS) rocket core stage Sept. 19. The stage will produce 2 million pounds of thrust to send Artemis I, the first flight SLS and NASA’s Orion spacecraft to the Moon. The engine section is located at the bottom of the 212-foot-tall stage and houses the four RS-25 engines. The core stage’s two liquid propellant tanks and four RS-25 engines will produce more than 2 million pounds of thrust to send the SLS rocket and Orion on the Artemis lunar missions. The engine section houses the four RS-25 engines and includes vital systems for mounting, controlling and delivering fuel form the propellant tanks to the rocket’s engines. 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. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission.

Technicians transported the assembled upper part of the Artemis II core stage to the final assembly area inside the factory at NASA’s Michoud Assembly Facility in New Orleans. On Jan 10, the forward assembly, left was moved next to the Artemis II liquid hydrogen tank, which has been undergoing assembly. Next, Boeing, the lead core stage contractor, will join the forward assembly and the liquid hydrogen tank to complete most of the core stage for the Space Launch System (SLS) rocket that will send the first crew on an Artemis mission. The core stage consists of five major structures that are built, outfitted, and then connected to form the final stage. The forward skirt, liquid oxygen and intertank were connected and tested to form the 66-foot forward assembly. After the forward assembly is joined with the 130-foot liquid hydrogen tank, only the engine section, the fifth piece of the stage, will need to be added to complete the Artemis II core stage. The core stage serves as the backbone of the rocket, supporting the weight of the payload, upper stage, and crew vehicle, as well as the thrust of its four RS-25 engines and two five-segment solid rocket boosters attached to the engine and intertank sections. On Artemis II, the SLS rocket will launch the Orion spacecraft and a crew, sending them into lunar orbit, in preparation for later Artemis missions that will enable the first woman and first person of color to land on the Moon.

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.

The engine section is located at the bottom of the core stage and includes the rocket’s main propulsion systems that connect to the core stage’s four RS-25 engines that will help launch the Artemis II lunar mission. This fall, the engine section will be horizontally integrated with the previously-joined forward assembly and liquid hydrogen tank to complete the core stage. NASA and core stage lead contractor Boeing are building core stages for the next three Artemis missions. The 212-foot core stage with its RS-25 engines will provide more than 2 million pounds of thrust at launch. With Artemis, NASA will land the first woman and the first person of color on the Moon and establish long-term 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. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission.

This image highlights the liquid hydrogen tank that will be used on the core stage of NASA’s Space Launch System rocket for Artemis II, the first crewed mission of NASA’s Artemis program. The tank is being built at NASA’s Michoud Assembly Facility in New Orleans. 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 hydrogen tank holds 537,000 gallons of liquid hydrogen cooled to minus 423 degrees Fahrenheit and sits between the core stage’s intertank and engine section. The liquid hydrogen hardware, along with the liquid oxygen tank, will provide propellant to the four RS-25 engines at the bottom of the cores 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.

Technicians at NASA’s Michoud Assembly Facility move the intertank of NASA’s Space Launch System rocket for Artemis III to Cell G to await application of the thermal protection system. Thermal protection systems protect space vehicles from aerodynamic heating during entry to planet atmosphere and re-entry to earth atmosphere. The intertank lays between the liquid hydrogen tank and liquid oxygen tank. Together with the engine section and the forward skirt, they comprise the SLS core stage. The liquid hydrogen tank and liquid oxygen tank hold 733,000 gallons of propellant to power the stage’s four RS-25 engines needed for liftoff and Artemis missions to the Moon and future missions to Mars.

This image shows the forward skirt that will be used on the core stage of NASA’s 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 hardware is located at the top of the 212-foot-tall core stage and connects the upper part of the rocket to the core stage. Soon, technicians will ready the forward skirt for the first of three core stage assembly mates called the forward join. The forward join consists of three main parts -- the forward skirt, liquid oxygen tank, and intertank – to create the top, or forward part, of the core stage. 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.

This photo shows all four RS-25 engines attached to the core stage for NASA’s Space Launch System rocket for the agency’s Artemis I mission to the Moon. To complete assembly of the rocket stage, engineers and technicians at NASA’s Michoud Assembly Facility in New Orleans are now integrating the propulsion and electrical systems within the structure. The completed core stage with all four RS-25 engines attached is the largest rocket stage NASA has built since the Saturn V stages for the Apollo Program that first sent Americans to the Moon. The stage, which includes two propellant tanks, provides more than 2 million pounds of thrust to send Artemis I to the Moon. Engineers and technicians attached the fourth RS-25 engine to the rocket stage Nov. 6 just one day after structurally mating the third engine. The first two RS-25 engines were structurally mated to the stage in October. After assembly is complete, crews will conduct an integrated functional test of flight computers, avionics and electrical systems that run throughout the 212-foot-tall core stage in preparation for its completion later this year. This testing is the first time all the flight avionics systems will be tested together to ensure the systems communicate with each other and will perform properly to control the rocket’s flight. Integration of the RS-25 engines to the recently completed core stage structure is a collaborative, multistep process for NASA and its partners Boeing, the core stage lead contractor, and Aerojet Rocketdyne, the RS-25 engines lead contractor. 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. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission.

Technicians at NASA’s Michoud Assembly Facility move the engine section of NASA’s Space Launch System rocket for Artemis IV out of Cell G after weld priming. 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.

Technicians transported the assembled upper part of the Artemis II core stage to the final assembly area inside the factory at NASA’s Michoud Assembly Facility in New Orleans. On Jan 10, the forward assembly, left was moved next to the Artemis II liquid hydrogen tank, which has been undergoing assembly. Next, Boeing, the lead core stage contractor, will join the forward assembly and the liquid hydrogen tank to complete most of the core stage for the Space Launch System (SLS) rocket that will send the first crew on an Artemis mission. The core stage consists of five major structures that are built, outfitted, and then connected to form the final stage. The forward skirt, liquid oxygen and intertank were connected and tested to form the 66-foot forward assembly. After the forward assembly is joined with the 130-foot liquid hydrogen tank, only the engine section, the fifth piece of the stage, will need to be added to complete the Artemis II core stage. The core stage serves as the backbone of the rocket, supporting the weight of the payload, upper stage, and crew vehicle, as well as the thrust of its four RS-25 engines and two five-segment solid rocket boosters attached to the engine and intertank sections. On Artemis II, the SLS rocket will launch the Orion spacecraft and a crew, sending them into lunar orbit, in preparation for later Artemis missions that will enable the first woman and first person of color to land on the Moon.

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.

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.

The core stage liquid hydrogen tank for the Artemis III mission completed proof testing, and technicians returned it to the main factory building at NASA’s Michoud Assembly Facility in New Orleans where it will undergo more outfitting. As part of proof testing, technicians apply a simple soap solution and check for leaks by observing any bubble formation on the welds. The technician removed the bubble solution with distilled water and then dried the area of application to prevent corrosion. To build the Space Launch System (SLS) rocket’s 130-foot core stage liquid hydrogen tank, engineers use robotic tools to weld five-barrel segments. This process results in a tank with around 1,900 feet, or more than six football fields, of welds that must be tested by hand. After the leak tests, the core stage lead, Boeing, pressurized the SLS tank to further ensure there were no leaks. After it passed proof testing, technicians moved the Artemis III liquid hydrogen tank to Michoud’s main factory. Soon, the technicians will prime and apply a foam-based thermal protection system that protects the tank during launch. Later, the tank will be joined with other parts of the core stage to form the entire 212-foot rocket stage with its four RS-25 engines that produce 2 million pounds of thrust to help launch the rocket. Artemis III will land the first astronauts on the lunar surface.
