NASA conducted another long-duration hot fire of an RS-25 engine May 10, continuing to pave the way for production of new engines for future deep space missions. Operators at the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, fired an RS-25 certification engine for more than 10 minutes (630 seconds). The test duration is longer than the 500 seconds the engines must fire to help launch the Space Launch System rocket on Artemis missions and helps provide a margin of operational safety. The engine also fired at 111% power level, the same level of thrust needed during launch, and at 113%, allowing operators to provide a margin of operational safety. The May 10 hot fire marked the seventh in a 12-test series designed to certify production of new RS-25 engines for future Artemis missions by lead contractor Aerojet Rocketdyne. Four RS-25 engines fire simultaneously, producing up to 2 million pounds of combined thrust, to help power each SLS launch.

The test on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, marked the eighth in a 12-test certification series that will support production of RS-25 engines by lead engine contractor Aerojet Rocketdyne for future Artemis missions, beginning with Artemis V. Engineers fired the RS-25 engine for almost eight-and-a-half minutes (500 seconds), the same amount of time it must operate to help send astronauts in the Orion spacecraft to space. The engine operated up to the 113% power level during the test, beyond the required 111% needed to get SLS to orbit. The increased power provides engineers with a margin of operational safety during testing.
Four RS-25 engines fire simultaneously to generate a combined 1.6 million pounds of thrust at launch and 2 million pounds of thrust during ascent to help power each SLS flight. Through Artemis, NASA will land the first woman and first person of color on the Moon and collaborate with commercial and international partners to establish the first long-term presence on the Moon. The agency will use what it learns on and around the Moon to then send the first astronauts to Mars.

Teams at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have completed applying a spray-on foam insulation to the launch vehicle stage adapter (LVSA) for the Artemis III mission. The LVSA is a cone-shaped piece of hardware that connects the SLS (Space Launch System) rocket’s upper and lower stages and partially encloses the engine of the interim cryogenic propulsion stage. The spray-on foam insulation is a type of thermal protection system that is used to protect the Moon rocket’s hardware from the extreme temperatures, forces, and sounds it’ll experience during launch and ascent. Unlike other parts of the mega rocket, the thermal protection system for the LVSA is applied entirely by hand using a tool similar to a spray gun. It is the largest piece of SLS hardware to be hand sprayed. Teams started applying the thermal protection system in March.
The LVSA in this video will be used for Artemis III, the mission that will land the first woman and first person of color on the lunar surface. The LVSA is fully manufactured at Marshall by NASA, lead contractor Teledyne Brown Engineering, and the Jacobs Space Exploration Group’s ESSCA contract.

Crews at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, worked April 19-20 to remove the first flight core stage of the agency’s Space Launch System rocket from the B-2 Test Stand in preparation for its transport to Kennedy Space Center in Florida. Operations required crews to lift the core stage from its vertical placement in the stand and lower it to a horizontal position on the B-2 Test Stand tarmac. The stage now will be loaded on NASA’s Pegasus barge for transport to Kennedy, where it will be prepared for launch of the Artemis I mission. Removal of the largest rocket stage ever built by NASA followed completion of a series of eight Green Run tests over the past year. During the Green Run series, teams performed a comprehensive test of the stand’s sophisticated and integrated systems. The series culminated in a hot fire of the stage’s four RS-25 engines on the B-2 stand March 18. During the hot fire, the four engines generated a combined 1.6 million pounds of thrust, just as during an actual launch. The test was the most powerful performed at Stennis in more than 40 years. NASA is building SLS, the world’s most powerful rocket, to return humans to deep space missions. As part of the backbone of NASA’s Artemis program, SLS will return humans, including the first woman and person of color, to the surface of the Moon to establish a sustainable presence and prepare for eventual missions to Mars.

NASA conducted its fourth RS-25 single-engine hot fire of the year May 20, a continuation of its seven-part test series to support development and production of engines for the agency’s Space Launch System (SLS) rocket on future missions to the Moon. The engine was fired for more than 8 minutes (500 seconds) on the A-1 Test Stand at Stennis Space Center near Bay St. Louis, the same amount of time RS-25 engines need to fire for launch of the SLS rocket. The test series is designed to provide valuable data to Aerojet Rocketdyne, prime contractor for the SLS engines, as it begins production of new engines for use after the first four SLS flights. Four RS-25 engines, along with a pair of solid rocket boosters, will help power SLS at launch. With testing of the engines for the rocket’s first four Artemis program missions to the Moon already completed, operators now are focused on collecting data to demonstrate and verify various engine capabilities while reducing operational risk. During the May 20 test, the team fired the engine at 111% of its original power level for a set duration of time, the same level that RS-25 engines are required to operate during launch. SLS is the most powerful rocket NASA has ever built and the only one capable of sending Orion, astronauts, and supplies to the Moon in a single mission. As part of the Artemis program, NASA will land the first woman and the first person of color on the Moon and establish sustainable exploration in preparation for missions to Mars. SLS and NASA’s Orion spacecraft, along with the commercial human landing system and the Gateway outpost in orbit around the Moon, are NASA’s backbone for deep space exploration. RS-25 tests at Stennis are conducted by a combined team of NASA, Aerojet Rocketdyne and Syncom Space Services operators. Syncom Space Services is the prime contractor for Stennis facilities and operations.

NASA conducted a long duration hot fire of an RS-25 certification engine March 21, continuing a key series of testing to support future Space Launch System (SLS) missions to deep space as part of Artemis missions as the agency continues to inspire the world through discovery.
Operators fired the certification engine for 10 minutes (600 seconds), longer than the 500 seconds engines must fire during an actual mission, on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Operators also fired the engine up to 113% power level, exceeding the 111% level needed during SLS launch. Hot fires of longer duration and higher power level allow operators to test the limits of engine performance and provide a margin of safety for flight operations. The March 21 hot fire was the fourth test in a series that began in early February to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne. The company is using advanced manufacturing techniques, such as 3D printing, to reduce the cost and time needed to build new engines for use on missions beginning with Artemis V. Four RS-25 engines help power SLS at launch, including on its Artemis missions to the Moon.
Through Artemis, NASA is returning humans, including the first woman and the first person of color, to the Moon to explore the lunar surface and prepare for flights to Mars. SLS is the only rocket capable of sending the agency's Orion spacecraft, astronauts, and supplies to the Moon in a single mission.

NASA conducted a long-duration RS-25 single-engine test April 28, continuing its seven-part test series to support development and production of engines for future missions of the agency’s Space Launch System (SLS) rocket. Operators fired the engine for almost 11 minutes (650 seconds) on the A-1 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi, providing valuable data to Aerojet Rocketdyne, lead contractor for the SLS engines, as it begins production of new engines for use after the first four SLS flights. Four RS-25 engines, along with a pair of solid rocket boosters, will help power SLS at launch. Engines for the rocket’s first four Artemis program missions to the Moon already have been tested. Operators now are focused on collecting data to demonstrate and verify various engine capabilities, evaluate new engine components manufactured with cutting-edge and cost-saving technologies, eliminate operating risks, and enhance engine production. The latest 650-second duration test represents the time three engines would have to fire to burn up propellant and power SLS to orbit, if the fourth engine shut down early during launch.

NASA conducted its sixth RS-25 single-engine hot fire Aug. 5 on the A-1 Test Stand at Stennis Space Center near Bay St. Louis, Mississippi, a continuation of its seven-part test series to support development and production of engines for the agency's Space Launch System (SLS) rocket on future missions to the Moon. Operators fired the engine for more than eight minutes (500 seconds), the same amount of time RS-25 engines need to fire for launch of the SLS rocket. Four RS-25 engines, with a pair of solid rocket boosters, will help power SLS at launch. NASA already has tested engines for the rocket's first four Artemis missions to the Moon, allowing operators to turn their focus towards collecting data to demonstrate and verify various engine capabilities for future engines. Along with providing performance data to Aerojet Rocketdyne, lead contractor for the SLS engines, the Aug. 5 test enabled the team to evaluate new engine components manufactured with cutting-edge and cost-saving technologies, eliminate operating risks, and enhance engine production. In addition to operating the engine at 109% of its original power level for extended periods during the hot fire, NASA verified new manufacturing processes while evaluating the performance of the engine's low-pressure fuel turbopump. The pump significantly boosts the pressure of liquid hydrogen delivered to the high-pressure fuel turbopump to help prevent cavitating, the forming of "bubbles" or "voids", which can collapse or cause shock waves that may damage machinery. NASA is building SLS as the world's most powerful rocket to send the agency's Orion spacecraft to the Moon.

The first four Artemis missions will use NASA’s 16 upgraded RS-25 engines that previously powered space shuttle flights. For future flights on the Space Launch System (SLS), NASA and prime contractor Aerojet Rocketdyne are changing the way they build major parts for the RS-25. Engineers and technicians are fabricating some of these parts using advanced manufacturing techniques that increase reliability while reducing both the cost and and time to build the engine.
The first RS-25 powerhead produced by Aerojet Rocketdyne in over a decade arrived at NASA’s Stennis Space Center near Bay St. Louis, Mississippi on Oct. 25. Here, it will be installed to a flight certification engine built specifically for testing newly designed parts for the latest production RS-25 engine that will power SLS flights beyond Artemis IV.
The powerhead serves as the structural backbone to the RS-25. It houses three highly complex injectors that produce the combustion to power the engine and acts as a junction for several critical parts, including both high pressure pumps and the main combustion chamber.

The fully stacked twin solid rocket boosters for NASA’s Space Launch System (SLS) rocket are mated atop the mobile launcher at the agency’s Kennedy Space Center in Florida as stacking and assembly activities for NASA’s Artemis I mission are underway. Crews from the spaceport’s Exploration Ground Systems and contractor Jacobs teams are currently preparing to lift the 188,000-pound core stage and place it in between the two solid rocket boosters. Teams will use a specialized crane to lift, place, and secure the core stage on the mobile launcher inside the spaceport’s iconic Vehicle Assembly Building (VAB).
The 212-foot-tall core stage, which will provide more than 2 million pounds of thrust at launch, arrived at Kennedy on April 27. Together with the two solid rocket boosters, the SLS rocket will provide more than 8.8 million pounds of thrust to launch the first of NASA’s next-generation Artemis Moon missions. Soon after the core stage activity, crews will stack and integrate other elements of the rocket needed for launch preparedness testing that occurs inside the VAB before final assembly of the rocket and the addition of the Orion spacecraft. The mobile launcher serves as a platform not just for stacking but as a key supplier of power, communications, coolants, and propellant for the rocket and spacecraft before launch.
With Artemis, NASA will land the first woman and the first person of color on the Moon and establish sustainable 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.

The rocket engine with one of the most storied histories in spaceflight, the RS-25, is returning to space for a second act – this time to send humans on the Artemis missions to explore the Moon.
As the space shuttle main engine, the RS-25 has a proven record of launching 135 missions spanning over three decades. At the end of the shuttle program in 2011, 16 RS-25 engines that helped build NASA’s International Space Station and deploy the Hubble Space Telescope, among other achievements, were stored away.
When NASA began scouting engines to power America’s next super heavy-lift rocket, the Space Launch System (SLS), the RS-25 offered an opportunity to forgo costs of developing a new engine, and the ability to leverage the assets, capabilities, and experience of the Space Shuttle Program.
Seen here in the RS-25 assembly deck at Aerojet Rocketdyne’s facility, located at NASA’s Stennis Space Center in Mississippi, are main engines 2057 and 2054, which will fly on the Artemis III crewed lunar mission.

The Space Launch System (SLS) rocket core stage for the Artemis I lunar mission has successfully completed its first four Green Run tests and is building on those tests for the next phase of checkout as engineers require more capability of the hardware before hot-firing the stage and its four powerful engines.
Green Run is a demanding series of eight tests and nearly 30 firsts: first loading of the propellant tanks, first flow through the propellant feed systems, first firing of all four engines, and first exposure of the stage to the vibrations and temperatures of launch.
Here, The Space Launch System (SLS) rocket is completing the Green Run test for the rocket’s core stage, shown installed on the top left side of the B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. For Green Run, the team is completing a series of eight tests culminating with Test 8, a full-up hot fire test that lasts eight minutes. Flames from the test will exit out of the yellow flame bucket shown here on the north side of the test stand. The B-2 test stand has dual positions and the right side of the stand is used for other testing. The SLS core stage is being tested for the first time testing prior to its use on the Artemis I lunar mission.

This week in 1968, the Saturn S-IC-6 arrived at the Mississippi Test Facility -- today’s NASA Stennis Space Center -- from the Michoud Assembly Facility. The S-IC, or first, stage of the Saturn rocket was powered by five F-1 engines, each producing 1.5 million pounds of thrust. The S-IC-6 was employed on the Apollo 11 Saturn V launch vehicle. Here, the S-IC-6 booster was lifted onto its mobile launcher in the Vehicle Assembly Building at Kennedy Space Center. Now through December 2022, NASA will mark the 50th anniversary of the Apollo Program that landed a dozen astronauts on the Moon between July 1969 and December 1972, and the first U.S. crewed mission -- Apollo 8 -- that circumnavigated the Moon in December 1968. The NASA History Program is responsible for generating, disseminating and preserving NASA's remarkable history and providing a comprehensive understanding of the institutional, cultural, social, political, economic, technological and scientific aspects of NASA 's activities in aeronautics and space.

NASA tested RS-25 engine No. 20001 on June 20, at the Fred Haise Test Stand at NASA’s Stennis Space Center at Bay St. Louis, Mississippi. Test teams fired the engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during a launch of an SLS (Space Launch System) rocket on Artemis missions to the Moon. The Artemis campaign will explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.
Four RS-25 engines, built by contractor L3Harris Technologies (formerly Aerojet Rocketdyne), help power each SLS launch, producing up to 2 million pounds of combined thrust. During the test, operators also fired engine No. 20001 up to the 111% power level, the same amount of thrust needed to launch an SLS rocket, carrying the Orion spacecraft, to orbit. The full-duration “hot fire” was the first test since NASA completed certification testing for new production RS-25 engines in 2024.

This week in 2017, NASA engineers completed the eighth and final RS-25 rocket engine hot fire test at NASA’s Stennis Space Center. The engine tested included a large 3D-printed part scheduled for use on future RS-25 flight engines that will power the core stage of NASA’S Space Launch System. The part was a beach ball-sized pogo accumulator assembly that acts as a shock absorber to dampen vibrations, or oscillations, caused by propellants as they flow between the vehicle and the engine. The hardware performed as expected, opening the door for more components scheduled for future tests. Today, NASA’s Marshall Space Flight Center is playing a vital role in the Artemis program by developing the SLS, the backbone of NASA’s exploration plans and the only rocket capable of sending humans to the Moon and Mars.

NASA Administrator Jim Bridenstine announced July 25 the agency will conduct an “Green Run” core stage test for the Space Launch System rocket ahead of the upcoming Artemis 1 lunar mission.
The first eight minutes of every Artemis mission with NASA’s Space Launch System (SLS) rocket will begin with core stage and solid rocket boosters producing 8.8 million pounds of thrust to launch the agency’s Orion spacecraft to the Moon. NASA will test the rocket’s 212-foot tall core stage -- the tallest rocket stage the agency has ever built -- with a “Green Run” test on Earth before launch day to help ensure mission success and pave the way for future Artemis missions carrying crew to the Moon. Missions at the Moon will be a stepping stone to prepare for human exploration of Mars.
The "Green Run" acceptance test of the core stage for NASA's Space Launch System (SLS) will be conducted at the B-2 Test Stand at NASA's Stennis Space Flight Center near Bay St. Louis, Mississippi. The historic test stand has been used to test stages for multiple programs, including the Saturn V and the space shuttle. Here, NASA's Space Launch System (SLS) core stage "Pathfinder" is positioned beside the B-2 Test Stand at NASA's Stennis Space Center near Bay St. Louis, Mississippi. The Pathfinder is the same shape, size and weight (without propellants loaded) as the actual SLS core stage.

The four women in charge of the effort to build and test the 212-foot-tall rocket stage that will enable NASA's first Artemis mission to the Moon watch as the first completed core stage for NASA's Space Launch System Program rolls out from the agency's Michoud Assembly Facility in New Orleans on Jan. 8, 2020. These key leaders are, from left, Lisa Bates, NASA Stages element deputy manager; Jennifer Boland-Masterson, Boeing Michoud production/operations manager; Julie Bassler, NASA Stages element manager; and, Noelle Zietsman, Boeing chief engineer. Each of these women manage the entire scope of design, development, testing and production of the complex core stage that will power the super heavy-lift rocket and the agency's Artemis lunar missions. Combined, the women have 90 years of experience in the aerospace and defense industries. Bassler and Bates previously held leadership positions within many NASA programs and projects, including International Space Station, space shuttle, microgravity experiments, robotic lunar landers and other launch vehicles. Â Manufacturing of the core stages for the SLS rocket is a multistep, collaborative process for NASA and Boeing, the core stage lead contractor. The first core stage for Artemis I is undergoing the core stage Green Run test series at NASA's Stennis Space Center near Bay St. Louis, Mississippi, ahead of the program's first launch. Michoud manufacturing teams are currently producing core stages for the second and third Artemis missions.
NASA is working to land the first woman and next man on the Moon by 2024. SLS is part of NASA’s backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon. SLS will be the most powerful rocket in the world and will send astronauts in the Orion spacecraft farther into space than ever before. No other rocket is capable of carrying astronauts in Orion around the Moon.
