Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Stennis Space Center enjoyed an active 2024, marking several milestones and engaging in frontline activities in several key areas. A compilation video offers a look at 2024 highlights in such areas of work as propulsion testing, autonomous systems, range operations, community outreach, and STEM engagement. NASA’s Stennis Space Center near Bay St. Louis, Mississippi, celebrated propulsion testing and site operations milestones in 2024, all while inspiring the Artemis Generation and welcoming new leadership that will help NASA Stennis innovate and grow into the future.
Featured highlights show a year of progress and vision, as NASA Stennis accelerates the exploration and commercialization of space, innovates to benefit NASA and industry, and leverages assets to grow as an impactful aerospace and technology hub.
“These highlights are just a small snapshot of 2024 at NASA Stennis that show the future is bright,” Bailey said. “We have an incredibly talented and committed team of employees – and all of Mississippi can be proud of the work they do here at NASA Stennis. Together, with the Artemis Generation leading the way, we are returning to the Moon. Together, we are a part of something great.”
New Center Leadership
NASA Stennis Director John Bailey, right, and NASA Stennis Deputy Director Christine Powell stand near the United States Capitol during a visit to Washington, D.C. on Sept. 18. It marked the first visit to Capitol Hill for the center leaders since being named to their current roles. NASA/Stennis NASA Administrator Bill Nelson named John Bailey as director of NASA Stennis in April. Bailey had been serving as acting director since January 2024. “So much of NASA runs through Stennis,” said Nelson. “It is where we hone new and exciting capabilities in aerospace, technology, and deep space exploration. I am confident that John will lead the nation’s largest and premier propulsion test site to even greater success.”
Four months later in August, Bailey announced that longtime propulsion engineer/manager Christine Powell had been selected as deputy director of NASA Stennis.
Powell, the first woman selected as NASA Stennis deputy director, began her 33-year agency career as an intern at the center in 1991. She previously worked in multiple Engineering and Test Directorate roles, and most recently served as manager of the NASA Rocket Propulsion Test Program Office.
Propulsion Activity
NASA achieves a major milestone for future Artemis missions with successful completion of the second – and final – RS-25 engine certification test series April 3 on the Fred Haise Test Stand at NASA’s Stennis Space Center. NASA/Danny Nowlin NASA achieved major milestones for future Artemis missions at NASA Stennis in 2024. The NASA Stennis test team successfully completed a second – and final – RS-25 engine certification test series in April. The mission-critical series verified engine upgrades designed to enhance efficiency and reliability for future SLS (Space Launch System) missions.
NASA Stennis crews also completed a safe lift and installation of the interstage simulator component in October needed for future testing of NASA’s exploration upper stage in the B-2 position of the Thad Cochran Test Stand. The component will function during Green Run testing like the SLS interstage section that helps protect the upper stage during Artemis launches.
The test complex milestones support NASA’s goal of returning humans to the Moon and paving the way for future Mars exploration through Artemis missions.
Commercial Testing
NASA Stennis commercial tenant Rocket Lab completes a successful hot fire test of its Archimedes engine in its onsite test complex in the second half of 2024. Rocket Lab is one of numerous customers conducting test campaigns at NASA Stennis during the most recent year. Rocket Lab Already the nation’s largest multiuser propulsion test site, NASA Stennis aims to continue fueling growth of the commercial space market even further by working with aerospace companies to support a range of testing needs. In 2024, NASA Stennis supported work conducted by commercial companies such as Boeing, Blue Origin, Evolution Space, Launcher (a Vast company), Relativity Space, Rocket Lab, and Rolls-Royce.
Officials from NASA Stennis and Roll-Royce also broke ground in June for a test pad located in the NASA Stennis E Test Complex. Rolls-Royce will conduct hydrogen testing for the Pearl 15 engine, which helps power the Bombardier Global 5500 & 6500 aircraft.
ASTRA Mission Success
Members of the NASA Stennis Autonomous Systems Laboratory team monitor the center’s in-space satellite payload from the onsite ASTRA (Autonomous Satellite Technology for Resilient Applications) Payload Operation Command Center. The ASTRA payload launched aboard the Sidus Space LizzieSat-1 small satellite in March 2024, with the NASA Stennis team announcing in July that it had achieved primary mission objectives. In September, the team announced the ASTRA mission would continue during the satellite’s planned four-year mission.NASA/Danny Nowlin In July, NASA Stennis and commercial partner Sidus Space Inc. announced primary mission success for the center’s historic in-space mission – an autonomous systems payload aboard an orbiting satellite.
ASTRA (Autonomous Satellite Technology for Resilient Applications) is the on-orbit payload mission developed by NASA Stennis. The NASA Stennis ASTRA technology demonstrator is a payload rider aboard the Sidus Space premier satellite, LizzieSat-1 (LS-1) small satellite. Partner Sidus Space is responsible for all LS-1 mission operations, including launch and satellite activation, which allowed the NASA Stennis ASTRA team to complete its primary mission objectives.
NASA Stennis announced in September it will continue the center’s in-space autonomous systems payload mission through a follow-on agreement with Sidus Space Inc.
Range Operations
The Skydweller Aero solar-powered, autonomous aircraft flies above the Thad Cochran Test Stand (B-1/B-2) at NASA’s Stennis Space Center during a September 2024 test operation. Skydweller Aero has an ongoing airspace agreement with NASA Stennis to conduct test flights of its aircraft in the area. Skydweller Aero During 2024, NASA Stennis entered into an agreement with Skydweller Aero Inc. for the company to operate its solar-powered autonomous aircraft in the site’s restricted airspace, a step towards achieving a strategic center goal.
The agreement marked the first Reimbursable Space Act agreement between NASA Stennis and a commercial company to utilize the south Mississippi center’s unique capabilities to support testing and operation of uncrewed systems.
The company announced in October it had completed an initial test flight campaign of the aircraft, including two test excursions totaling 16 and 22.5 hours.
NASA Engagement
NASA Stennis representatives inspire the Artemis Generation at the NAS Pensacola Blue Angels Homecoming Air Show on Nov. 1-2. NASA’s exhibits at the air show honored 55th anniversary of the Apollo 11 lunar landing and showcased the agency’s mission to inspire the world through discovery. NASA/Stennis NASA representatives participated in a variety of outreach activities during the past year to create meaningful connections with the Artemis Generation.
The NASA ASTRO CAMP® Community Partners program, which originated at the south Mississippi NASA center, surpassed previous milestone marks in fiscal year 2024 by partnering with 373 community sites, including 50 outside the United States, to inspire youth, families, and educators.
NASA Stennis also supported STEM (science, technology, engineering, and mathematics) engagement during the year. It once again joined with NASA’s Robotics Alliance Project and co-sponsor Mississippi Power to support the second annual For the Inspiration and Recognition of Science and Technology (FIRST) Robotics Magnolia Regional Competition in Laurel, Mississippi. The event attracted 37 high school teams from eight states and one from Mexico.
The center also supported NASA activities during the 2024 total solar eclipse. In addition, it hosted informational efforts and exhibits at high-visibility events such as the 51st Annual Bayou Classic, and Essence Fest in New Orleans.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Knowing whether or not a planet elsewhere in the galaxy could potentially be habitable requires knowing a lot about that planet’s sun. Sarah Peacock relies on computer models to assess stars’ radiation, which can have a major influence on whether or not one of these exoplanets has breathable atmosphere.
Name: Sarah Peacock
Title: Assistant Research Scientist
Formal Job Classification: Astrophysicist
Organization: Exoplanets and Stellar Astrophysics Laboratory, Astrophysics Division, Science Directorate (Code 667)
Sarah Peacock is a research scientist with the Exoplanets and Stellar Astrophysics Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Md.Courtesy of Sarah Peacock What do you do and what is most interesting about your role here at Goddard?
My overarching research goal is to find habitable planets in other solar systems. To do this, I study the high-energy radiation that specific stars produce to help determine if life can exist on any earthlike planets that orbit them.
What is your educational background?
In 2013, I received a Bachelor of Arts in astrophysics from the University of Virginia. I received both my master’s and doctorate degrees from the Lunar and Planetary Laboratory at the University of Arizona in 2016 and 2019, respectively.
What drew you to study the stars?
In high school, I took an astronomy class. We had a planetarium in our school and I had a wonderful teacher who inspired me to fall in love with the stars. She also showed us how many of the Harry Potter characters are drawn from the constellations and that spoke to my heart because I am a Harry Potter fan!
How did you come to Goddard?
I started at Goddard as a NASA post-doctoral fellow in July 2020, but I first saw the center the day before Goddard shut down due to COVID.
How does high-energy radiation show you what planets outside our solar system might be habitable?
High-energy radiation can cause a planet to lose its atmosphere. If a planet is exposed to too much high-energy radiation, the atmosphere can be blown off, and if there is no atmosphere, then there is nothing for life as we know it to breathe.
We cannot directly measure the specific radiation that I study, so we have to model it. The universe has so many stars, and almost all stars host a planet. There are approximately 5,500 confirmed exoplanets so far, with an additional 7,500 unconfirmed exoplanets.
I help identify systems that either have too much radiation, so planets in the habitable zone (the region around a star where liquid water could exist on a planet’s surface) are probably lifeless, or systems that have radiation levels that are safer. Ultimately, my research helps narrow down the most likely systems to host planets that should have stable atmospheres.
Sarah Peacock research goal is to find habitable planets in other solar systems.Courtesy of Sarah Peacock Where does your data come from?
I predominately use data from the Hubble Space Telescope and from the now-retired spacecraft GALEX. My work itself is more theory-focused though: I create a modeled stellar spectrum across all wavelengths and use observations to validate my modeling.
What other areas of research are you involved in?
I am working with a team analyzing data from the James Webb Space Telescope to see if earthlike planets around M-type stars (a star that is cooler and smaller than the Sun) have atmospheres and, if so, what the composition of those atmospheres is. An exciting result from this work is that we may have detected water in the atmosphere of a rocky planet for the first time ever. However, we cannot yet distinguish with our current observations if that water comes from the planet or from spots on the star (starspots on this host star are cold enough for water to exist in gas form).
I am also helping manage a NASA Innovative Advance Concept (NIAC) study led by my mentor, Ken Carpenter, to work on the Artemis Enabled Stellar Imager (AeSI). If selected for further development, this imager would be an ultraviolet/optical interferometer located on the South Pole of the Moon. With this telescope, we would be able to map the surface of stars, image accretion disks, and image the centers of Active Galactic Nuclei.
As a relatively new employee to Goddard, what have been your first impressions?
Everyone who I have met, especially those in my lab, are incredibly friendly and welcoming. Starting during the pandemic, I was worried about feeling isolated, but instead, I was blown away by how many folks in my lab reached out to set up calls to introduce themselves and suggest opportunities for collaboration. It made me feel welcome.
Who is your mentor and what did your mentor advise you?
Ken Carpenter is my mentor. He encourages me to pursue my aspirations. He supports letting me chart my own path and being exposed to many different areas of research. I thank Ken for his support and encouragement and for including me on his projects.
“Everyone who I have met, especially those in my lab, are incredibly friendly and welcoming.”Courtesy of Sarah Peacock What do you do for fun?
I am a new mom, so my usual hobbies are on pause! Right now, fun is taking care of my baby and introducing life experiences to him.
As a recently selected member of the Executive Committee for NASA’s Exoplanet Exploration Program Analysis Group (ExoPAG), what are your responsibilities?
The NASA ExoPAG is responsible for soliciting and coordinating scientific community input into the development and execution of NASA’s exoplanet exploration program. We solicit opinions and advice from any scientist who studies exoplanets. We are a bridge between NASA’s exoplanet scientists and NASA Headquarters in Washington.
What is a fun fact about yourself?
I got married the same day I defended my Ph.D. I had my defense in the morning and got married in the afternoon at the courthouse.
Who is your favorite author?
I love to read; I always have three books going. My favorite author is Louise Penny, who writes mysteries, but I read all genres. Right now, I am reading a biography about Marjorie Merriweather Post.
What is your favorite quote?
“The most that can be expected from any model is that it can supply a useful approximation to reality: All models are wrong; some models are useful.” —Box and Draper 1987
