The Space Launch System (SLS) liquid hydrogen tank structural test article is loaded into Test Stand 4693 at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on Jan. 14, 2019. The 149-foot piece of test hardware is the largest piece of structural hardware for the SLS core stage for America’s new deep space rocket Itis structurally identical to the flight version of the tank. It will undergo a series of tests in Test Stand 4693 to 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.

Inside the Launch Abort System Facility (LASF) at NASA’s Kennedy Space Center in Florida, workers are completing the integration of a test version of the Orion crew module with the Launch Abort System (LAS) on May 18, 2019. The test vehicle and the LAS will be used for the Orion Ascent Abort-2 (AA-2) Flight Test. AA-2 is a full-stress test of the LAS, planned for July 2. AA-2 will launch from Space Launch Complex 46, carrying a fully functional LAS and a 22,000-pound Orion test vehicle to an altitude of 31,000 feet and traveling at more than 1,000 miles an hour. The test will verify the LAS can steer the crew module and astronauts aboard to safety if an emergency occurs during ascent on the Space Launch System (SLS) rocket. NASA's Orion and Exploration Ground Systems programs, contractors Jacob's, Lockheed Martin and Northrop Grumman, in conjunction with the Air Force Space and Missile Center's Launch Operations branch and the 45th Space Wing are performing flight operations for AA-2.

This collection of photos shows the steps NASA engineers took to lift the final structural test article for NASA’s Space Launch System (SLS) core stage into Test Stand 4697 at NASA’s Marshall Space Flight Center in Huntsville, Alabama, July 10, 2019. The liquid oxygen (LOX) tank is one of two propellant tanks in the rocket’s massive core stage that will produce more than 2 million pounds of thrust to help launch Artemis 1, the first flight of NASA’s Orion spacecraft and SLS, to the Moon. The nearly 70-foot-long liquid oxygen tank structural test article was manufactured at NASA’s Michoud Assembly Facility in New Orleans and delivered by NASA’s barge Pegasus to Marshall. Once bolted into the test stand, dozens of hydraulic cylinders will push and pull the tank, subjecting it to the same stresses and forces it will endure during liftoff and flight, to verify it is fit for flight.

Technicians at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are seen in these images taken April 17, 2025, moving the payload adapter test article from Building 4697 to Building 4705 for storage. This move marks the end of structural testing for the test article. Next, engineers will complete the qualification article and conduct additional for further testing before building the final flight hardware. Manufactured at Marshall, the test article underwent extensive and rigorous testing to validate the design before engineers finalized the configuration for the flight article. The newly completed composite payload adapter is an evolution from the Orion stage adapter to be used in the upgraded Block 1B configuration of the SLS (Space Launch System) rocket, debuting with Artemis IV.

This move marks the end of structural testing for the test article. Next, engineers will complete the qualification article and conduct additional for further testing before building the final flight hardware. Manufactured at Marshall, the test article underwent extensive and rigorous testing to validate the design before engineers finalized the configuration for the flight article.

The test version of Orion attached to the Launch Abort System for the Ascent Abort-2 (AA-2) flight test is moved by crane into the vertical integration facility at Space Launch Complex 46 at Cape Canaveral Air Force Station in Florida on May 23, 2019. The flight test article will be stacked atop the booster, which was procured by the U.S. Air Force and manufactured by Northrop Grumman. During AA-2, targeted for July 2, the LAS with Orion will launch on the booster more than six miles in altitude, where Orion’s launch abort system will pull the capsule and its crew away to safety if an emergency occurs during ascent on the Space Launch System rocket. AA-2 is a critical safety test that helps pave the way for Artemis missions near the Moon, and will enable astronauts to set foot on the lunar surface by 2024.

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.

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.

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.

Photo shows how the Space Launch Sysetm (SLS) rocket liquid oxygen tank failed during a structural qualification test at NASA’s Marshall Space Flight Center in Huntsville, Alabama. The photos show both the water flowing from the tank as it ruptured and the resultant tear left in the tank when it buckled during the test. Engineers pushed the liquid oxygen structural test article to the limits on purpose. The tank is a test article that is identical to tanks that are part of the SLS core stage that will produce 2 million pounds of thrust to help launch the rocket on the Artemis missions to the Moon. During the test, hydraulic cylinders were then calibrated and positioned along the tank to apply millions of pounds of crippling force from all sides while engineers measured and recorded the effects of the launch and flight forces. For the test, water used to simulate the liquid oxygen flows out of the tank after it ruptures. The structural test campaign was conducted on the rocket to ensure the SLS rocket’s structure can endure the rigors of launch and safely send astronauts to the Moon on the Artemis missions.

NASA’s Cross Flow Attenuated Natural Laminar Flow test article is mounted beneath the agency’s F-15 research aircraft ahead of the design’s high-speed taxi test on Tuesday, Jan. 12, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California. The 3-foot-tall scale model is designed to increase a phenomenon known as laminar flow and reduce drag, improving efficiency in large, swept wings like those found on most commercial aircraft.
