Technicians at Michoud Assembly Facility in New Orleans lift the core stage that will help launch the first crewed flight of NASA’s SLS (Space Launch System) rocket for the agency’s Artemis II mission. Teams at Michoud lifted the core stage on Thursday, July 11, 2024, onto NASA’s Multi-Purpose Transportation System, designed to transport SLS vehicle segments by waterway and roadway. It is tasked with transporting the vehicle from where it is manufactured to its intermediate test location and final launch destination. The core stage was lifted in preparation for its move onto the agency’s Pegasus barge, where it will be ferried to NASA’s Kennedy Space Center in Florida. Pegasus is maintained at Michoud. The core stage for the SLS mega rocket is the largest stage NASA has ever produced. At 212 feet tall, the stage consists of five major elements, including two huge propellant tanks that collectively hold more than 733,000 gallons of super chilled liquid propellant to feed four RS-25 engines at its base. During launch and flight, the stage will operate for just over eight minutes, producing more than 2 million pounds of thrust to help send a crew of four astronauts inside NASA’s Orion spacecraft onward to the Moon. All the major structures for every SLS core stage are fully manufactured at NASA Michoud. NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft and Gateway in orbit around the Moon and commercial human landing systems, next-generation space, next-generational spacesuits, and rovers on the lunar surface. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. Image credit: NASA/Michael DeMocker

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.

A supermoon rises over Huntsville, Alabama, home to NASA’s Marshall Space Flight Center, Aug. 19. Visible through Wednesday, Aug. 21, the full Moon is both a supermoon and a Blue Moon. Supermoons are the biggest and brightest full Moons of the year because the Moon is within 90% of its closest point to Earth. While not blue in color, the third full Moon in a season with four full Moons is called a “Blue Moon.” Huntsville is known as the “Rocket City” because of its proximity to NASA Marshall, which manages vital propulsion systems and hardware, launch vehicles, engineering technologies, and cutting-edge science for the agency.

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. 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.

Technicians at NASA’s Michoud Assembly Facility in New Orleans on Feb. 22 prepare elements that will form part of the midbody for the future exploration upper stage for the SLS (Space Launch System) rocket. The midbody struts, or V-struts, will create the midbody’s cage-like outer structure to connect the upper stage’s larger liquid hydrogen tank to its smaller liquid oxygen tank. Manufacturing flight and test hardware for the future SLS upper stage is a collaborative effort between NASA and Boeing, the lead contractor for EUS and the SLS core stage. Beginning with Artemis IV, SLS will evolve to its more powerful Block 1B configuration with the advanced exploration upper stage that gives the rocket the capability to launch 40% more to the Moon along with Artemis astronauts inside NASA’s Orion spacecraft. The evolved in-space stage for SLS will use a combination of liquid oxygen and liquid hydrogen propellants to help power the engines to send large cargo and crew inside Orion to the Moon.

NASA astronaut Victor Glover views the core stage of the SLS (Space Launch System) rocket that will help power Artemis II at NASA’s Michoud Assembly Facility in New Orleans July 15. Glover will pilot Artemis II, the first crewed mission of NASA’s Artemis campaign. Crews moved the 212-foot-tall core stage with its four RS-25 engines to Building 110 at NASA Michoud prior to rolling it out to NASA’s Pegasus barge July 16 for delivery to NASA’s Kennedy Space Center in Florida. The core stage has two giant propellant tanks that collectively hold more than 733,000 gallons of super cold liquid propellant to feed the stage’s four RS-25 engines. Together, the engines produce more than 2 million pounds of thrust to help send astronauts inside NASA’s Orion spacecraft to venture around the Moon for Artemis II. NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

This image shows teams at NASA’s Michoud Assembly Facility lifting a completed dome off of a robotic weld tool on Nov. 21. The dome, which will cap off the aft end of the liquid hydrogen tank, will be used on the core stage of the SLS (Space Launch System) rocket for the agency’s Artemis IV mission. Later, technicians from Boeing – NASA’s prime contractor for SLS – will join the aft dome with five barrels and a forward dome to complete the liquid hydrogen tank. Artemis IV is the first flight of SLS in its Block 1B configuration. The SLS core stage liquid hydrogen tank holds 537,000 gallons of super-cooled propellant and is one of five unique elements that make up the SLS core stage. Together with the forward skirt, liquid oxygen tank, intertank, and engine section, 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.

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.

A supermoon rises over Huntsville, Alabama, home to NASA’s Marshall Space Flight Center, Aug. 19. Visible through Wednesday, Aug. 21, the full Moon is both a supermoon and a Blue Moon. Supermoons are the biggest and brightest full Moons of the year because the Moon is within 90% of its closest point to Earth. While not blue in color, the third full Moon in a season with four full Moons is called a “Blue Moon.” Huntsville is known as the “Rocket City” because of its proximity to NASA Marshall, which manages vital propulsion systems and hardware, launch vehicles, engineering technologies, and cutting-edge science for the agency.

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 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.
