Through NASA’s Artemis campaign, astronauts will land on the lunar surface and use a new generation of spacesuits and rovers as they live, work, and conduct science in the Moon’s South Pole region, exploring more of the lunar surface than ever before. Recently, the agency completed the first round of testing on three commercially owned and developed LTVs (Lunar Terrain Vehicle) from Intuitive Machines, Lunar Outpost, and Venturi Astrolab at NASA’s Johnson Space Center in Houston.NASA/Bill Stafford Venturi Astrolab’s FLEX, Intuitive Machines’ Moon RACER, and Lunar Outpost’s Eagle lunar terrain vehicle – three commercially owned and developed LTVs (Lunar Terrain Vehicle) – are pictured at NASA’s Johnson Space Center in Houston in this photo from Nov. 21, 2024.
As part of an ongoing year-long feasibility study, each company delivered a static mockup of their vehicle to Johnson at the end of September, initiated rover testing in October and completed the first round of testing in December inside the Active Response Gravity Offload System (ARGOS) test facility. Lunar surface gravity is one-sixth of what we experience here on Earth, so to mimic this, ARGOS offers an analog environment that can offload pressurized suited subjects for various reduced gravity simulations.
See how these LTVs were tested.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Stennis Space Center near Bay St. Louis, Mississippi, is helping the Artemis Generation learn how to power space dreams with an interactive exhibit at INFINITY Science Center.
The engine test simulator exhibit at the official visitor center of NASA Stennis provides the chance to experience the thrill of being a NASA test engineer by guiding an RS-25 engine through a simulated hot fire test.
“It is an exhilarating opportunity to feel what it is like to be a NASA engineer, responsible for making sure the engine is safely tested for launch,” said Chris Barnett-Woods, a NASA engineer that helped develop the software for the exhibit.
Sitting at a console mirroring the actual NASA Stennis Test Control Center, users are immersed in the complex process of engine testing. The exhibit uses cutting-edge software and visual displays to teach participants how to manage liquid oxygen and liquid hydrogen propellants, and other essential elements during a hot fire.
A pair of young visitors to INFINITY Science Center carry out the steps of a simulated RS-25 engine hot fire on Dec. 19. The updated engine test simulator exhibit provided by NASA’s Stennis Space Center takes users through the hot fire process just as real engineers do at NASA Stennis.NASA/Danny Nowlin INFINITY Science Center, the official visitor center for NASA’s Stennis Space Center, has unveiled a new interactive simulator exhibit that allows visitors to become the test conductor for an RS-25 engine hot fire. NASA/Danny Nowlin Users follow step-by-step instructions that include pressing buttons, managing propellant tanks, and even closing the flare stack, just as real engineers do at NASA Stennis. Once the test is complete, they are congratulated for successfully conducting their own rocket engine hot fire.
The interactive exhibit is not just about pushing buttons. It is packed with interesting facts about the RS-25 engine, which helps power NASA’s Artemis missions as the agency explores secrets of the universe for the benefit of all. Visitors also can view real hot fires conducted at NASA Stennis from multiple angles, deepening their understanding of rocket propulsion testing and NASA’s journey back to the Moon and beyond.
NASA is currently preparing for the Artemis II mission, the first crewed flight test of the agency’s powerful SLS (Space Launch System) rocket and the Orion spacecraft around the Moon.
The first four Artemis missions are using modified space shuttle main engines tested at NASA Stennis. The center also achieved a testing milestone last April for engines to power future Artemis missions. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power NASA’s SLS rocket, producing more than 8.8 million pounds of total combined thrust at liftoff.
The revitalized exhibit, previously used when the visitor center was located onsite, represents a collaborative effort. It started as an intern project in the summer of 2023 before evolving into a full-scale experience. Engineers built on the initial concept, integrating carpentry, audio, and video to create the seamless experience to educate and inspire.
The best part might be that visitors to INFINITY Science Center can repeat the simulation as many times as they like, gaining confidence and learning more with each attempt.
“This exhibit was a favorite in the past, and with its new upgrades, the engine test simulator is poised to capture the imaginations of the Artemis Generation at INFINITY Science Center,” said NASA Public Affairs Specialist Samone Wilson. “This is one exhibit you will not want to miss.” INFINITY Science Center is located at 1 Discovery Circle, Pearlington, Mississippi.

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.

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.
