This image shows the latest progress NASA has made in manufacturing the liquid oxygen tank for the second core stage of NASA’s Space Launch System (SLS) rocket. The liquid oxygen tank will be used for the first crewed mission, Artemis II, of the agency’s Artemis program. Teams at NASA’s Michoud Assembly Facility in New Orleans recently completed internal cleaning of the liquid oxygen, or LOX, tank at the facility. Following the cleaning, crews prepared the propellant tank for the next phase of phase of assembly in a different area of the factory by moving, or breaking over, the tank from a vertical to horizontal position. The LOX tank is one of five major elements that make up the rocket’s massive 212-foot-tall core stage. The propellant tank holds 196,000 gallons of supercooled liquid oxygen to help fuel four RS-25 engines, and the internal cleaning ensures no contaminants make their way into the complex propulsion and engine systems of the deep space rocket. The stage, which includes a cluster of four RS-25, will produce more than 2 million pounds of thrust to help launch the SLS rocket and astronauts aboard NASA’s Orion spacecraft around the Moon for Artemis II. NASA is working to land the first woman and the next man on the Moon by 2024. The agency’s SLS rocket offers more payload mass, volume capability and energy to speed missions through deep space and enable NASA’s Artemis lunar program. SLS, along with Orion, the human landing system, and the Gateway in orbit around the Moon are NASA’s backbone for deep space exploration. No other rocket is capable of carrying astronauts in Orion around the Moon in a single mission.

The Space Launch System (SLS) rocket’s liquid oxygen tank structural test article was manufactured and stacked in June 2019 at NASA’s Michoud Assembly Facility in New Orleans. To construct the test article, Boeing technicians at Michoud moved the liquid oxygen tank to the Vertical Assemby Building stacking and integration area. Here, they added simulators to mimic the two structures that connect to the tank, the intertank and the forward skirt. This structural hardware for the SLS core stage for America’s new deep space rocket is structurally identical to the flight version of the tank. It will be shipped on the Pegasus barge to NASA’s Marshall Space Flight Center in Hunstville, Alabama, where it will undergo a series of tests that simulate the stresses and loads of liftoff and flight. These tests will help ensure designs are adequate for successful SLS missions to the Moon and beyond. The flight liquid oxygen tank along with the liquid hydrogen tank supplies more than 500,000 gallons of propellant to the core stages four RS-25 engines, which produce 2 million pounds of thrust to help send the SLS rocket to space.

These images show how the team rolled out 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.

The Space Launch System (SLS) rocket’s liquid oxygen tank structural test article was manufactured and stacked in June 2019 at NASA’s Michoud Assembly Facility in New Orleans. To construct the test article, Boeing technicians at Michoud moved the liquid oxygen tank to the Vertical Assemby Building stacking and integration area. Here, they added simulators to mimic the two structures that connect to the tank, the intertank and the forward skirt. This structural hardware for the SLS core stage for America’s new deep space rocket is structurally identical to the flight version of the tank. It will be shipped on the Pegasus barge to NASA’s Marshall Space Flight Center in Hunstville, Alabama, where it will undergo a series of tests that simulate the stresses and loads of liftoff and flight. These tests will help ensure designs are adequate for successful SLS missions to the Moon and beyond. The flight liquid oxygen tank along with the liquid hydrogen tank supplies more than 500,000 gallons of propellant to the core stages four RS-25 engines, which produce 2 million pounds of thrust to help send the SLS rocket to space.

These images show how the team rolled out 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.

CS2 Hardware Update

Technicians at NASA’s Michoud Assembly Facility in New Orleans moved the engine section for NASA’s Space Launch System (SLS) rocket to another part of the facility on Sept. 3 to prepare it for joining to the rest of the rocket’s core stage. The engine section, which comprises the lowest portion of the 212-foot-tall stage, is the last major component to be horizontally integrated to the core stage. Michoud crews completed assembly on the flight hardware that will be used for Artemis I, the first lunar mission of SLS and NASA’s Orion spacecraft, on Aug. 29. NASA and Boeing engineers removed the scaffolding surrounding the hardware to use a special tool to properly position the engine section for its attachment to the rest of the stage. 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.

These images show how teams at NASA’s Michoud Assembly Facility in New Orleans moved the core stage, complete with all four RS-25 engines, for NASA’s Space Launch System (SLS) rocket to Building 110 for final shipping preparations on Jan. 1. The SLS core stage includes state-of-the-art avionics, propulsion systems and two colossal propellant tanks that collectively hold 733,000 gallons of liquid oxygen and liquid hydrogen to power its four RS-25 engines. The completed stage, which will provide more than 2 million pounds of thrust to help power the first Artemis mission to the Moon, will be shipped via the agency’s Pegasus barge from Michoud to NASA’s Stennis Space Center near Bay St. Louis, Mississippi, later this month. 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.
