These photos and videos show how crews at NASA’s Marshall Space Flight Center in Huntsville, Alabama, moved and installed the payload adapter that will be used in the Block 1B configuration of the SLS (Space Launch System) rocket from Building 4708, where it was manufactured, into Structural Test Stand 4697 at NASA’s Marshall Space Flight Center on March 13. Teams at Marshall will begin structural testing the engineering development unit of the payload adapter – an exact replica of the flight version of the hardware – this spring. The cone-shaped payload adapter is about 8.5 feet tall and features two metal rings and eight composite panels. The adapter, which will debut on NASA’s Artemis IV mission, is an evolution from the Orion stage adapter used in the Block 1 configuration of the first three Artemis missions. It will be housed inside the universal stage adapter atop the rocket’s more powerful in-space stage, called the exploration upper stage. The payload adapter, like the launch vehicle stage adapter and the Orion stage adapter, is fully manufactured and tested at Marshall, which manages the SLS Program. 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-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.

These photos show how technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have applied the thermal protection system material to the launch vehicle stage adapter (LVSA) of NASA’s SLS (Space Launch System) rocket for Artemis III, which will land astronauts on the Moon to advance long-term lunar exploration and scientific discovery and inspire the Artemis Generation. The LVSA is a cone-shaped element that connects the mega rocket’s core stage to its interim cryogenic propulsion stage (ICPS), partially enclosing it and protecting its avionics and electrical systems from the extreme pressures, sounds, and temperatures during launch and flight. Teams at Marshall began applying the thermal protection system material in the spring of 2023. Unlike other parts of the SLS rocket, the thermal protection system material for the LVSA is applied entirely by hand using a spray gun. During application, the technicians use a thin measuring rod to gauge the proper thickness. Once the thermal protection system has cured, certain areas are sanded down to meet parameters. The entire process takes several months. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Group’s ESSCA contract. The LVSA for Artemis III is the last of its kind as future SLS rockets will transition to its next, more powerful Block 1B configuration beginning with Artemis IV.

These photos and videos show how crews guided a test version of the universal stage adapter for NASA’s more powerful version of its SLS (Space Launch System) rocket to Building 4619 at the agency’s Marshall Space Flight Center in Huntsville, Alabama, Feb. 22. Built by Leidos, the lead contractor for the universal stage adapter, crews transported the hardware from a Leidos facility in Decatur, Alabama, the same day. The universal stage adapter will connect the SLS rocket’s upgraded in-space propulsion stage, called the exploration upper stage, to NASA’s Orion spacecraft as part of the evolved Block 1B configuration of the SLS rocket. It will also serve as a compartment capable of accommodating large payloads, such as modules or other exploration spacecraft. In Building 4619’s Load Test Annex High Bay at Marshall, the development test article will first undergo modal testing that will shake the hardware to validate dynamic models. Later, during ultimate load testing, force will be applied vertically and to the sides of the hardware. Unlike the flight hardware, the development test article has flaws intentionally included in its design, which will help engineers verity that the flight adapter can withstand the extreme forces it will face during launch and flight.

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.

These photos and videos show how NASA manufactured and prepared to transport the payload adapter in February inside Building 4708 at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Prior to moving the hardware for testing, teams installed the New Explorations Secondary Transport component, called the NEST, into the top of the engineering development unit. The NEST component will allow the hardware to hold a series of secondary payloads, or small satellites. The cone-shaped payload adapter is about 8.5 feet tall and features two metal rings and eight composite panels. The adapter, which will debut on NASA’s Artemis IV mission, is an evolution from the Orion stage adapter used in the Block 1 configuration of the rocket for the first three Artemis missions. It will be housed inside the universal stage adapter atop the rocket’s more powerful in-space stage, called the exploration upper stage. The payload adapter, like the launch vehicle stage adapter and the Orion stage adapter, is fully manufactured and tested at Marshall, which manages the SLS Program. 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-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.

These photos show the launch vehicle stage adapter (LVSA) of NASA’s SLS (Space Launch System) rocket for Artemis III before technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, applied the thermal protection system to it. Artemis III will land astronauts on the Moon to advance long-term lunar exploration and scientific discover and inspire the Artemis Generation. Teams at Marshall began applying the thermal protection system material in the spring of 2023. Unlike other parts of the SLS rocket, the thermal protection system material for the LVSA is applied entirely by hand using a spray gun. During application, the technicians use a thin measuring rod to gauge the proper thickness. Once the thermal protection system has cured, certain areas are sanded down to meet parameters. The entire process takes several months. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Group’s ESSCA contract. The LVSA for Artemis III is the last of its kind as future SLS rockets will transition to its next, more powerful Block 1B configuration beginning with Artemis IV.

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.

These images and videos show how crews in Alabama prepared the ICPS (interim cryogenic propulsion stage) for NASA’s SLS (Space Launch System) rocket for shipment to Florida between July 29-31. The ICPS in the photos and videos will help power NASA’s Artemis III mission to the Moon. The SLS upper stage is manufactured by United Launch Alliance at its facility in Decatur. Its RL10 engine is produced by Aerojet Rocketdyne, the SLS engines lead contractor, in West Palm Beach, Florida. ULA is working with Boeing, the SLS core stage and exploration upper stage lead contractor, to develop ICPS. ULA’s R/S RocketShip is transporting the flight hardware to its sister facility in Florida near NASA’s Kennedy Space Center for final checkouts. The ICPS for Artemis III is the last of its kind as SLS transitions to its next, more powerful Block 1B configuration with an upgraded upper stage beginning with Artemis IV.

These photos and videos show how crews guided a test version of the universal stage adapter for NASA’s more powerful version of its SLS (Space Launch System) rocket to Building 4619 at the agency’s Marshall Space Flight Center in Huntsville, Alabama, Feb. 22. Built by Leidos, the lead contractor for the universal stage adapter, crews transported the hardware from a Leidos facility in Decatur, Alabama, the same day. The universal stage adapter will connect the SLS rocket’s upgraded in-space propulsion stage, called the exploration upper stage, to NASA’s Orion spacecraft as part of the evolved Block 1B configuration of the SLS rocket. It will also serve as a compartment capable of accommodating large payloads, such as modules or other exploration spacecraft. In Building 4619’s Load Test Annex High Bay at Marshall, the development test article will first undergo modal testing that will shake the hardware to validate dynamic models. Later, during ultimate load testing, force will be applied vertically and to the sides of the hardware. Unlike the flight hardware, the development test article has flaws intentionally included in its design, which will help engineers verity that the flight adapter can withstand the extreme forces it will face during launch and flight.
