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.

NASA’s X-59 quiet supersonic research aircraft completed its first maximum afterburner test at Lockheed Martin’s Skunk Works facility in Palmdale, California. This full-power test, during which the engine generates additional thrust, validates the additional power needed for meeting the testing conditions of the aircraft. The X-59 is the centerpiece of NASA’s Quesst mission, which aims to overcome a major barrier to supersonic flight over land by reducing the noise of sonic booms.Lockheed Martin Corporation/Garry Tice NASA completed the first maximum afterburner engine run test on its X-59 quiet supersonic research aircraft on Dec. 12. The ground test, conducted at Lockheed Martin’s Skunk Works facility in Palmdale, California, marks a significant milestone as the X-59 team progresses toward flight.
An afterburner is a component of some jet engines that generates additional thrust. Running the engine, an F414-GE-100, with afterburner will allow the X-59 to meet its supersonic speed requirements. The test demonstrated the engine’s ability to operate within temperature limits and with adequate airflow for flight. It also showed the engine’s ability to operate in sync with the aircraft’s other subsystems.
The X-59 is the centerpiece of NASA’s Quesst mission, which seeks to solve one of the major barriers to supersonic flight over land by making sonic booms quieter. The X-59’s first flight is expected to occur in 2025.
