During missions to the Moon, RS-25 engines fire for about 500 seconds and up to the 111% power level to help launch SLS, with the Orion spacecraft, into orbit.
The engine arrived at the test stand from the L3Harris Engine Assembly Facility on the engine transport trailer before being lifted onto the vertical engine installer (VEI) on the west side deck. After rolling the engine into the stand, the team used the VEI to raise and secure it in place.
The upcoming acceptance test follows two certification test series that helped verify the new engine production process and components meet all performance requirements. Four RS-25 engines help launch SLS, producing up to 2 million pounds of combined thrust.
All RS-25 engines for Artemis missions are tested and proven flightworthy at NASA Stennis prior to use. RS-25 tests are conducted by a team of operators from NASA, L3Harris, and Syncom Space Services, prime contractor for site facilities and operations.

“We’re trying to tap into the community college talent pool to bring new students to the table for aeronautics,” said Steven Holz, who manages the USRC award process. “Innovation comes from everywhere, and people with different viewpoints, educational backgrounds, and experiences like those in our community colleges are also interested in aeronautics and looking to make a difference.”
Real World Research Awards
Through USRC, students interact with real-world aspects of the research ecosystem both in and out of the laboratory. They will manage their own research projects, utilize state-of-the-art technology, and work alongside accomplished aeronautical researchers. Students are expected to make unique contributions to NASA’s research priorities.
USRC provides more than just experience in technical research.
Each team of students selected receives a USRC grant from NASA – and is tasked with the additional challenge of raising funds from the public through student-led crowdfunding. The process helps students develop skills in entrepreneurship and public communication.
The new university teams and research topics are:
Cerritos Community College
“Project F.I.R.E. (Fire Intervention Retardant Expeller)” will explore how to mitigate wildfires by using environmentally friendly fire-retardant pellets dropped from drones. Cerritos Community College’s team includes lead Angel Ortega Barrera as well as Larisa Mayoral, Paola Mayoral Jimenez, Jenny Rodriguez, Logan Stahl, and Juan Villa, with faculty mentor Janet McLarty-Schroeder. This team also successfully participated with the same research topic in in NASA’s Gateway to Blue Skies competition, which aims to expand engagement between the NASA’s University Innovation project and universities, industry, and government partners.
Colorado School of Mines
The project “Design and Prototyping of a 9-phase Dual-Rotor Motor for Supersonic Electric Turbofan” will work on a scaled-down prototype for an electric turbofan for supersonic aircraft. The Colorado School of Mines team includes lead Mahzad Gholamian as well as Garret Reader, Mykola Mazur, and Mirali Seyedrezaei, with faculty mentor Omid Beik.

You would not expect to see NASA at a car show—but that’s exactly where Johnson Space Center employees were from Jan. 29 to Feb. 2, 2025, driving the future of space exploration forward.
At the Houston AutoBoative Show, a fusion of the auto and boat show, NASA rolled out its Artemis exhibit at NRG Center for the first time, introducing motor enthusiasts to the technologies NASA and commercial partners will use to explore more of the lunar surface than ever before.
Johnson Space Center employees present the Artemis exhibit at the 2025 Houston AutoBoative Show at NRG Center.NASA/Robert Markowitz The Artemis exhibit stood alongside some of the world’s most advanced cars and boats, offering visitors an up-close look at lunar terrain vehicle mockups from Astrolab, Intuitive Machines, and Lunar Outpost. Later this year, NASA will select the rover that will fly to the Moon as humanity prepares for the next giant leap.
In addition to the rovers, the exhibit featured a mockup of JAXA’s (Japan Aerospace Exploration Agency) pressurized rover, designed as a mobile habitat for astronauts, and Axiom Space’s lunar spacesuit, developed for Artemis III astronauts.
These capabilities will allow astronauts to explore, conduct science research, and live and work on the lunar surface.

NASA/Robert Markowitz Johnson Director Vanessa Wyche visited the Artemis exhibit to highlight the importance of these technologies in advancing lunar exploration. Every lesson learned on the Moon will help scientists and engineers develop the strategies, technologies, and experience needed to send astronauts to Mars.
“By bringing the excitement of lunar exploration to the AutoBoative Show, NASA aims to inspire the next generation of explorers to dream bigger, push farther, and help shape humanity’s future in space,” Wyche said.
NASA’s Artemis campaign is setting the stage for long-term human exploration, working with commercial and international partners to establish a sustained presence on the Moon before progressing to Mars.
To make this vision a reality, NASA is developing rockets, spacecraft, landing systems, spacesuits, rovers, habitats, and more.
Vanessa Wyche views Axiom Space’s lunar spacesuit at the exhibit. NASA/Robert Markowitz Some of the key elements on display at the show included:
The Orion spacecraft – Designed to take astronauts farther into deep space. Orion will launch atop NASA’s Space Launch System (SLS) rocket, carrying the crew to the Moon on Artemis missions and safely returning them to Earth. Lunar terrain vehicles – Developed to transport astronauts across the rugged lunar surface or be remotely operated. NASA recently put these rover mockups to the test at Johnson, where astronauts and engineers, wearing spacesuits, ran through critical maneuvers, tasks, and emergency drills—including a simulated crew rescue. Next-gen spacesuits and tools – Through Johnson’s Extravehicular Activity and Human Surface Mobility Program, astronauts’ gear and equipment are designed to ensure safety and efficiency while working on the Moon’s surface.

February’s Night Sky Notes: How Can You Help Curb Light Pollution?
Light pollution has long troubled astronomers, who generally shy away from deep sky observing under full Moon skies. The natural light from a bright Moon floods the sky and hides views of the Milky Way, dim galaxies and nebula, and shooting stars. In recent years, human-made light pollution has dramatically surpassed the interference of even a bright full Moon, and its effects are now noticeable to a great many people outside of the astronomical community. Harsh, bright white LED streetlights, while often more efficient and long-lasting, often create unexpected problems for communities replacing their old street lamps. Some notable concerns are increased glare and light trespass, less restful sleep, and disturbed nocturnal wildlife patterns. There is increasing awareness of just how much light is too much light at night. You don’t need to give in to despair over encroaching light pollution; you can join efforts to measure it, educate others, and even help stop or reduce the effects of light pollution in your community.
Before and after pictures of replacement lighting at the 6th Street Bridge over the Los Angeles River. The second picture shows improvements in some aspects of light pollution, as light is not directed to the sides and upwards from the upgraded fixtures, reducing skyglow. However, it also shows the use of brighter, whiter LEDs, which is not generally ideal, along with increased light bounce back from the road. City of Los Angeles Amateur astronomers and potential citizen scientists around the globe are invited to participate in the Globe at Night (GaN) program to measure light pollution. Measurements are taken by volunteers on a few scheduled days every month and submitted to their database to help create a comprehensive map of light pollution and its change over time. GaN volunteers can take and submit measurements using multiple methods ranging from low-tech naked-eye observations to high-tech sensors and smartphone apps.
Globe at Night citizen scientists can use the following methods to measure light pollution and submit their results:
Their own smartphone camera and dedicated app Manually measure light pollution using their own eyes and detailed charts of the constellations A dedicated light pollution measurement device called a Sky Quality Meter (SQM). The free GaN web app from any internet-connected device (which can also be used to submit their measurements from an SQM or printed-out star charts) Night Sky Network members joined a telecon with Connie Walker of Globe at Night in 2014 and had a lively discussion about the program’s history and how they can participate. The audio of the telecon, transcript, and links to additional resources can be found on their dedicated resource page.
Light pollution has been visible from space for a long time, but new LED lights are bright enough that they stand out from older street lights, even from orbit. The above photo was taken by astronaut Samantha Cristoforetti from the ISS cupola in 2015. The newly installed white LED lights in the center of the city of Milan are noticeably brighter than the lights in the surrounding neighborhoods. NASA/ESA DarkSky International has long been a champion in the fight against light pollution and a proponent of smart lighting design and policy. Their website (at darksky.org) provides many resources for amateur astronomers and other like-minded people to help communities understand the negative impacts of light pollution and how smart lighting policies can not only help bring the stars back to their night skies but make their streets safer by using smarter lighting with less glare. Communities and individuals find that their nighttime lighting choices can help save considerable sums of money when they decide to light their streets and homes “smarter, not brighter” with shielded, directional lighting, motion detectors, timers, and even choosing the proper “temperature” of new LED light replacements to avoid the harsh “pure white” glare that many new streetlamps possess. Their pages on community advocacy and on how to choose dark-sky-friendly lighting are extremely helpful and full of great information. There are even local chapters of the IDA in many communities made up of passionate advocates of dark skies.
DarkSky International has notably helped usher in “Dark Sky Places“, areas around the world that are protected from light pollution. “Dark Sky Parks“, in particular, provide visitors with incredible views of the Milky Way and are perfect places to spot the wonders of a meteor shower. These parks also perform a very important function, showing the public the wonders of a truly dark sky to many people who may have never before even seen a handful of stars in the sky, let alone the full, glorious spread of the Milky Way.
More research into the negative effects of light pollution on the health of humans and the environment is being conducted than ever before. Watching the nighttime light slowly increase in your neighborhood, combined with reading so much bad news, can indeed be disheartening! However, as awareness of light pollution and its negative effects increases, more people are becoming aware of the problem and want to be part of the solution. There is even an episode of PBS Kid’s SciGirls where the main characters help mitigate light pollution in their neighborhood!
Astronomy clubs are uniquely situated to help spread awareness of good lighting practices in their local communities in order to help mitigate light pollution. Take inspiration from Tucson, Arizona, and other dark sky-friendly communities that have adopted good lighting practices. Tucson even reduced its skyglow by 7% after its own citywide lighting conversion, proof that communities can bring the stars back with smart lighting choices.
