Start Your Engines: NASA to Begin Critical Testing for Future Artemis Missions

NASA will begin a new RS-25 test series Oct. 5, the final round of certification testing ahead of production of an updated set of the engines for the SLS (Space Launch System) rocket. The engines will help power future Artemis missions to the Moon and beyond.

A series of 12 tests stretching into 2024 is scheduled to occur on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The tests are a key step for lead SLS engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to produce engines that will help power the SLS rocket, beginning with Artemis V.

“NASA and our industry partners continue to make steady progress toward restarting production of the RS-25 engines for the first time since the space shuttle era as we prepare for our more ambitious missions to deep space under Artemis with the SLS rocket,” said Johnny Heflin, liquid engines manager for SLS at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The upcoming fall test series builds off previous hot fire testing already conducted at NASA Stennis to help certify a new design that will make this storied spaceflight engine even more powerful.”

For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS rocket, producing more than 8.8 million pounds of thrust at liftoff. Following a “test like you fly” approach, all 12 tests in the new series are scheduled for at least 500 seconds, the same amount of time the engines must fire during an actual launch.

The 12-test series will use developmental engine E0525 to collect data for the final RS-25 design certification review. The engine features a second set of new key components, including a nozzle, hydraulic actuators, flex ducts, and turbopumps. The components match design features of those used during the initial certification test series completed at the south Mississippi site in June.

“Testing a second set of hardware during this next phase of our certification test series will give us repeatability to ensure we have sound processes for building our new engines,” said Mike Lauer, RS-25 deputy program manager at Aerojet Rocketdyne. “The successful testing of the brand-new certification engine proved our engineering was sound – that the new design is capable of meeting requirements at operating extremes and durations. This next test series will help confirm our manufacturing processes will reliably create production engines that will meet these same requirements.”

Operators will fire the engine at power levels varying between 80% and 113% to test performance in multiple scenarios. The first four Artemis missions are using modified space shuttle main engines that can power up to 109% of their rated level. New RS-25 engines will power up to the 111% level to provide additional thrust. Testing up to the 113% power level provides a margin of operational safety.

The longest test of the new series is planned for 650 seconds. Crews will conduct a gimbal test of the engine to ensure it can pivot as needed to help SLS maintain stability and trajectory during flight. The Oct. 5 test is scheduled for 550 seconds and will fire the RS-25 engine up to 111% power level.

Overall, a total of 6,350 seconds of hot fire is planned for the series. With completion of the campaign, it is anticipated all systems will be “go” to produce 24 new RS-25 engines using the updated design for missions beginning with Artemis V.

“Testing at the historic Fred Haise Test Stand is critical to ensure that our astronauts fly safely,” said Chip Ellis, project manager for RS-25 testing at NASA Stennis. “The test team takes great care to ensure these engines will operate as designed to launch NASA payloads and astronauts to the Moon and beyond.”

Through Artemis, NASA will use innovative technologies and collaborate with commercial and international partners to explore more of the Moon than ever. The agency will use what is learned on and around the Moon to take the next giant leap of sending the first astronauts to Mars.

NASA and Bastion: A Collaborative Teamwork Advancing Deep Space Exploration and Ensuring Safety in Missions  

As we continue to celebrate Hispanic Heritage Month, the NASA Office of Small Business Programs is pleased to share the contributions of Bastion Technologies Inc. (Bastion), a Hispanic-owned company that supports NASA’s missions. Their primary role is in Safety & Mission Assurance at NASA’s Marshall Space Flight Center in Huntsville, Alabama. This includes systems engineering, where they have worked on design and analysis activities for the International Space Station, space shuttle, and Artemis programs. 

Bastion engages in critical assessments to ensure the highest standards of safety and reliability in NASA missions. Their team provides mission assurance support for both crewed and uncrewed flight systems at various other NASA centers such as Stennis Space Center, Ames Research Center, Glenn Research Center, and NASA’s Jet Propulsion Laboratory. In addition to supporting the success of NASA missions, they have prioritized the safety of our astronauts and valuable payloads. As a result, Bastion has received the Marshall Space Flight Center Safety Award for maintaining an exemplary safety record, with 2 million work hours without any injuries.  

NASA has also recognized Bastion with the Space Flight Awareness Award for their role in multiple aspects of the Space Launch Program, particularly in ensuring the successful delivery and launch of the Artemis I launch vehicle.  During Artemis I, NASA’s SLS (Space Launch System), soared into the sky and sent the Orion spacecraft on a 1.4-million-mile journey beyond the Moon and back. The Space Launch System is NASA’s heavy-lift rocket and serves as the cornerstone for human exploration beyond Earth’s orbit. The SLS is the only rocket capable of sending the Orion spacecraft, four astronauts, and transporting extensive cargo directly to the Moon within a single mission.  

They have also aided in a 12-test series of the new RS-25 engines at the agency’s Stennis Space Center in Mississippi, which are integral to future SLS rocket missions. For over three decades, the RS-25 engine powered the space shuttle, completing 135 missions. This engine stands as one of the most rigorously tested large rocket engines in history, with over 3,000 starts and an accumulated firing time exceeding 1 million seconds through ground tests and flight. Throughout the Space Shuttle Program, the RS-25 underwent numerous design enhancements aimed at improving durability, reliability, safety, and performance. 

Furthermore, Bastion’s assistance in projects such as the Sample Cartridge Assembly and Copper Indium Sulfide Defect Growth  has been critical in completing the CISDG-C1 hardware for shipment and launch on the 28th SpaceX commercial resupply services mission for NASA. It launched to the International Space Station from the agency’s Kennedy Space Center in Florida on June 3, 2023.  On this mission, SpaceX’s Dragon spacecraft transported several thousand pounds of essential hardware,  scientific experiments, and technology demonstrations. It also encompassed research on plant stress adaptation, investigations into genetic structures known as telomeres, as well as the deployment of satellite projects designed by Canadian students.  

Lastly, Bastion’s contribution to the Life Science Glovebox payload has seen a significant increase, with them completing 2.5 times as many integrated safety assessments in 2023 as they did in 2022. The Life Sciences Glovebox is a sealed work area in the International Space Station  which provides bioisolation and waste control. Crew members can perform experimental procedures in cell, insect, aquatic, plant, and animal developmental biology. 

Jorge Hernandez, the CEO of Bastion Technologies Inc. shares how his unique identity as a Hispanic professional continues to influence his daily work with NASA and Bastion in profound ways.  “Growing up in a culturally rich and diverse background, I have brought a unique perspective to problem-solving and teamwork. I’ve learned to adapt to different challenges and appreciate the value of diversity in the workplace,” says Hernandez.   

He goes on to emphasize that Bastion actively supports mentorship and advocates for underrepresented minorities in STEM fields, aiming to inspire the next generation of diverse professionals to reach for the stars.  

“Bastion’s journey supporting NASA has been deeply influenced by my heritage, which has driven our company to excel and promote diversity within the agency. Bastion is proud to contribute to NASA’s mission and play our part in advancing our understanding of the universe.” – Jorge Hernandez
