Preparations for Next Moonwalk Simulations Underway (and Underwater)
Note: The following article is part of a series highlighting propulsion testing at NASA’s Stennis Space Center. To access the entire series, please visit: https://www.nasa.gov/feature/propulsion-powering-space-dreams/.
Crews at NASA’s Stennis Space Center work Jan. 21-22, 2020, to install the first flight core stage of NASA’s powerful SLS (Space Launch System) rocket on the B-2 side of the Thad Cochran Test Stand for a Green Run test series. Operations required crews to lift the massive core stage from a horizontal position into a vertical orientation, a procedure known as “break over.” Once the stage was oriented in a horizontal position on the night of Jan. 21, crews tied it in place to await favorable wind conditions. The following morning, crews began the process of raising, positioning, and securing the stage on the stand. NASA/Stennis The future is now at NASA’s Stennis Space Center near Bay St. Louis, Mississippi – at least when it comes to helping power the next great era of human space exploration.
NASA Stennis is contributing directly to the agency’s effort to land the first woman, the first person of color, and its first international partner astronaut on the Moon – for the benefit of all humanity. Work at the nation’s largest – and premier – propulsion test site will help power SLS (Space Launch System) rockets on future Artemis missions to enable long-term lunar exploration and prepare for the next giant leap of sending the first astronauts to Mars.
“We play a critical role to ensure the safety of astronauts on future Artemis missions,” NASA Stennis Space Center Director John Bailey said. “Our dedicated workforce is excited and proud to be part of NASA’s return to the Moon.”
NASA Stennis achieved an RS-25 testing milestone in April at the Fred Haise Test Stand. Completion of the successful RS-25 certification series provided critical data for L3Harris (formerly known as Aerojet Rocketdyne) to produce new RS-25 engines, using modern processes and manufacturing techniques. The engines will help power SLS rockets beginning with Artemis V.
The first four Artemis missions are using modified space shuttle main engines also tested at NASA Stennis. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS rocket to produce more than 8.8 million pounds of total combined thrust at liftoff.
NASA’s powerful SLS rocket is the only rocket that can send the Orion spacecraft, astronauts, and cargo to the Moon on a single mission.
Following key test infrastructure upgrades near the Fred Haise Test Stand, NASA Stennis will be ready for more RS-25 engine testing. NASA has awarded L3Harris contracts to provide 24 new engines, supporting SLS launches for Artemis V through Artemis IX.
“Every RS-25 engine that launches Artemis to space will be tested at NASA Stennis,” said Joe Schuyler, director of the NASA Stennis Engineering and Test Directorate. “We take pride in helping to power this nation’s human space exploration program. We also take great care in testing these engines because they are launching astronauts to space. We always have safety in mind.”
NASA’s Stennis Space Center conducts a successful hot fire of the first flight core stage of NASA’s powerful SLS (Space Launch System) rocket on the B-2 side of the Thad Cochran Test Stand on March 18, 2021. NASA employees, as well as NASA astronauts Jessica Meir and Zena Cardman, watched the milestone moment. The hot fire of more than eight minutes marked the culmination of a Green Run series of tests on the stage and its integrated systems. NASA/Stennis In addition to RS-25 testing, preparations are ongoing at the Thad Cochran Test Stand (B-2) for future testing of the agency’s new exploration upper stage. The more powerful SLS second stage, which will send astronauts and cargo to deep space aboard the Orion spacecraft, is being built at NASA’s Michoud Assembly Facility in New Orleans.
Before its first flight, the NASA Stennis test team will conduct a series of Green Run tests on the new stage’s integrated systems to demonstrate it is ready to fly. Crews completed installation of a key component for testing the upper stage in October. The lift and installation of the 103-ton interstage simulator component, measuring 31 feet in diameter and 33 feet tall, provided crews best practices for moving and handling the actual flight hardware when it arrives to NASA Stennis.
The exploration upper stage Green Run test series will culminate with a hot fire of the stage’s four RL10 engines, made by L3Harris, the lead SLS engines contractor.
“All of Mississippi shares in our return to the Moon with the next great era of human space exploration going through NASA Stennis,” Bailey said. “Together, we can be proud of the state’s contributions to NASA’s great mission.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Jacquelyn Shuman visually assesses a prescribed fire at Ft. Stewart in Georgia, working with partner organizations as part of the Department of Defense Ft. Stewart 2024 Fire Research Campaign. USFS/Linda Chappell Jacquelyn Shuman, FireSense Project Scientist at NASA Ames Research Center, originally wanted to be a veterinarian. By the time she got to college, Shuman had switched interests to biology, which became a job teaching middle and high school science. Teaching pivoted to finance for a year, before Shuman returned to the science world to pursue a PhD.
It was in a forest ecology class taught by her future PhD advisor, Herman “Hank” Shugart, that she first discovered a passion for ecosystems and dynamic vegetation that led her into the world of fire science, and eventually to NASA Ames.
While Shuman’s path into the world of fire science was not a direct one, she views her diverse experiences as the key to finding a fulfilling career. “Do a lot of different things and try a lot of different things, and if one thing isn’t connecting with you, then do something different,” Shuman said.
Diving into the World of Fire
Shuman’s PhD program focused on boreal forest dynamics across Russia, examining how the forest changes in response to climate change and wildfire. During her research, she worked mainly with scientists from Russia, Canada, and the US through the Northern Eurasia Earth Science Partnership Initiative (NEESPI), where Shugart served as the NEESPI Chief Scientist. “The experience of having a highly supportive mentor, being a part of the NEESPI community, and working alongside other inspiring female scientists from across the globe helped me to stay motivated within my own research,” Shuman said.
After completing her PhD, Shuman wanted to become involved in collaborative science with a global impact, which led her to the National Center for Atmospheric Research (NCAR). There, she spent seven years working as a project scientist on the Next Generation Ecosystem Experiment NGEE-Tropics) on a dynamic vegetation model project called FATES (Functionally Assembled Terrestrial Ecosystem Simulator). As part of the FATES team, Shuman used computer modeling to test vegetation structure and function in tropical and boreal forests after wildfires, and was the lead developer for updating the fire portion of the model.
This figure shows fire characteristics from an Earth system model that uses vegetation structure and interactive fire. The FATES model captures the fire intensity associated with burned land and grass growth in the Southern Hemisphere. Shuman et al. 2024 GMD Fire has also played a powerful role in Shuman’s personal life. In 2021, the Marshall Fire destroyed neighborhoods near her hometown of Boulder, Colorado, causing over $513 million of damage and securing its place as the state’s most destructive wildfire. Despite this, Shuman is determined to not live in fear. “Fire is part of our lives, it’s a part of the Earth system, and it’s something we can plan for. We can live more sustainably with fires.” The way to live safely in a fire-inclusive ecosystem, according to Shuman, is to develop ways to accurately track and forecast wildfires and smoke, and to respond to them efficiently: efforts the fire community is continuously working on improving.
The Fire Science Community
Collaboration is a critical element of wildland fire management. Fire science is a field that involves practitioners such as firefighters and land managers, but also researchers such as modelers and forecasters; the most effective efforts, according to Shuman, come when this community works together. “People in fire science might be out in the field and carrying a drip torch and marching along in the hilltops and the grasslands or be behind a computer and analyzing remote sensing data,” Shuman said. “We need both pieces.”
Protecting communities from wildfire impacts is one of the most fulfilling aspects of Shuman’s career, and a goal that unites this community. “Fire research poses tough questions, but the people who are thinking about this are the people who are acting on it,” Shuman said. “They are saying, ‘What can we do? How can we think about this? What information do we need? What are the questions?’ It’s a special community to be a part of.”
Looking to the Future of Fire
Currently at NASA Ames Research Center, Shuman is the Project Scientist for FireSense: a project focused on delivering NASA science and technology to practitioners and operational agencies. Shuman acts as the lead for the project office, identifying and implementing tools and strategies. Shuman still does ecosystem modeling work, including implementing vegetation models that forecast the impact of fire, but also spends time traveling to active fires across the country so she can help partners implement NASA tools and strategies in real time.

“Right now, many different communities are all recognizing that we can partner to identify the best path forward,” Shuman said. “We have an opportunity to use everyone’s strengths and unique perspectives. It can be a devastating thing for a community and an ecosystem when a fire happens. Everyone is interested in using all this collective knowledge to do more, together.”
