NASA’s Artemis campaign will send astronauts, payloads, and science experiments into deep space on NASA’s SLS (Space Launch System) super heavy-lift Moon rocket. Starting with Artemis IV, the Orion spacecraft and its astronauts will be joined by other payloads atop an upgraded version of the SLS, called Block 1B. SLS Block 1B will deliver initial elements of a lunar space station designed to enable long term exploration of the lunar surface and pave the way for future journeys to Mars. To fly these advanced payloads, engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are building a cone-shaped adapter that is key to SLS Block 1B.
At NASA Marshall, the PLA engineering development unit is installed into the 4697-test stand for structural testing. It was then attached to the large cylindrical structure which simulates the Exploration Upper Stage interface. Load lines were then connected to the top of the PLA. The testing demonstrated that it can handle up to three times the expected load.NASA/Samuel Lott The payload adapter, nestled within the universal stage adapter sitting atop the SLS Block 1B’s exploration upper stage, acts as a connecting point to secure a large payload that is co-manifested – or flying along with – the Orion spacecraft. The adapter consists of eight composite panels with an aluminum honeycomb core and two aluminum rings.
Beginning with the Artemis IV mission, SLS Block 1B will feature a new, more powerful upper stage that provides a substantial increase in payload mass, volume, and energy over the first variant of the rocket that is launching Artemis missions I through III. SLS Block 1B can send 84,000 pounds of payload – including both a crewed Orion spacecraft and a 10-metric ton (22,046 lbs.) co-manifested payload riding in a separate cargo compartment – to the Moon in a single launch.
Artemis IV’s co-manifested payload will be the Lunar I-Hab, one of the initial elements of the Gateway lunar space station. Built by ESA (European Space Agency), the Lunar I-Hab provides expanded capability for astronauts to live, work, conduct science experiments, and prepare for their missions to the lunar surface.
Before the Artemis IV mission structure was finalized, NASA engineers needed to design and test the new payload adapter.
“With SLS, there’s an intent to have as much commonality between flights as possible,” says Brent Gaddes, Lead for the Orion Stage Adapter and Payload Adapter in the SLS Spacecraft/Payload Integration & Evolution Office at NASA Marshall.
However, with those payloads changing typically every flight, the connecting payload adapter must change as well.
“We knew there needed to be a lot of flexibility to the payload adapter, and that we needed to be able to respond quickly in-house once the payloads were finalized,” says Gaddes.
Working alongside the robots, NASA’s next generation of engineers are learning from experts with decades of manufacturing expertise as they prepare the metal honeycomb structure substrate. During production, the fingerprints of the engineers are imprinted where metal meets composite. Even after the finishing touches are applied, the right light at the right angle reveals the harmless prints of the adapter’s makers as it launches payloads on SLS that will enable countless discoveries.NASA/Samuel Lott A Flexible Approach
The required flexibility was not going to be satisfied with a one-size-fits-all approach, according to Gaddes.
Since different size payload adapters could be needed, Marshall is using a flexible approach to assemble the payload adapter that eliminates the need for heavy and expensive tooling used to hold the parts in place during assembly. A computer model of each completed part is created using a process called structured light scanning. The computer model provides the precise locations where holes need to be drilled to hold the parts together so that the completed payload adapter will be exactly the right size.
“Structured light has helped us reduce costs and increase flexibility on the payload adapter and allows us to pivot,” says Gaddes. “If the call came down to build a cargo version of SLS to launch 40 metric tons, for example, we can use our same tooling with the structured light approach to adapt to different sizes, whether that’s for an adapter with a larger diameter that’s shorter, or one with a smaller diameter that’s longer. It’s faster and cheaper.”
NASA Marshall engineers use an automated placement robot to manufacture eight lightweight composite panels from a graphite epoxy material. The robot performs fast, accurate lamination following preprogrammed paths, its high speed and precision resulting in lower cost and significantly faster production than other manufacturing methods.
At NASA Marshall, an engineering development unit of the payload has been successfully tested which demonstrated that it can handle up to three times the expected load. Another test version currently in development, called the qualification unit, will also be tested to NASA standards for composite structures to ensure that the flight unit will perform as expected.
“The payload adapter is shaped like a cone, and historically, most of the development work on structures like this has been on cylinders, so that’s one of the many reasons why testing it is so important,” says Gaddes. “NASA will test as high a load as possible to learn what produces structural failure. Any information we learn here will feed directly into the body of information NASA has pulled together over the years on how to analyze structures like this, and of course that’s something that’s shared with industry as well. It’s a win for everybody.”
With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of the Red Planet. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the human landing system, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

Artistic rendering of Intuitive Machines’ Nova-C lander on the surface of the Moon.Credit: Intuitive Machines NASA’s Polar Resources Ice Mining Experiment-1 (PRIME-1) is preparing to explore the Moon’s subsurface and analyze where lunar resources may reside. The experiment’s two key instruments will demonstrate our ability to extract and analyze lunar soil to better understand the lunar environment and subsurface resources, paving the way for sustainable human exploration under the agency’s Artemis campaign for the benefit of all.
Its two instruments will work in tandem: The Regolith and Ice Drill for Exploring New Terrains (TRIDENT) will drill into the Moon’s surface to collect samples, while the Mass Spectrometer Observing Lunar Operations (MSOLO) will analyze these samples to determine the gas composition released across the sampling depth. The PRIME-1 technology will provide valuable data to help us better understand the Moon’s surface and how to work with and on it.
“The ability to drill and analyze samples at the same time allows us to gather insights that will shape the future of lunar resource utilization,” said Jackie Quinn, PRIME-1 project manager at NASA’s Kennedy Space Center in Florida. “Human exploration of the Moon and deep space will depend on making good use of local resources to produce life-sustaining supplies necessary to live and work on another planetary body.”
The PRIME-1 experiment is one of the NASA payloads aboard the next lunar delivery through NASA’s CLPS (Commercial Lunar Payload Services) initiative, set to launch from the agency’s Kennedy Space Center no earlier than Wednesday, Feb. 26, on Intuitive Machines’ Athena lunar lander and explore the lunar soil in Mons Mouton, a lunar plateau near the Moon’s South Pole.
Developed by Honeybee Robotics, a Blue Origin Company, TRIDENT is a rotary percussive drill designed to excavate lunar regolith and subsurface material up to 3.3 feet (1 meter) deep. The drill will extract samples, each about 4 inches (10 cm) in length, allowing scientists to analyze how trapped and frozen gases are distributed at different depths below the surface.
The TRIDENT drill is equipped with carbide cutting teeth to penetrate even the toughest lunar materials. Unlike previous lunar drills used by astronauts during the Apollo missions, TRIDENT will be controlled from Earth. The drill may provide key information about subsurface soil temperatures as well as gain key insight into the mechanical properties of the lunar South Pole soil. Learning more about regolith temperatures and properties will greatly improve our understanding of the environments where lunar resources may be stable, revealing what resources may be available for future Moon missions.
A commercial off-the-shelf mass spectrometer, MSOLO, developed by INFICON and made suitable for spaceflight at Kennedy, will analyze any gas released from the TRIDENT drilled samples, looking for the potential presence of water ice and other gases trapped beneath the surface. These measurements will help scientists understand the Moon’s potential for resource utilization.
Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA is one of many customers on future flights. PRIME-1 was funded by NASA’s Space Technology Mission Directorate Game Changing Development program.

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.

Dr. Peyman Abbaszadeh poses outside Princeton University, where he is a postdoctoral research associate in the department of civil and environmental engineering. Peyman’s research area is computational hydrology and satellite data assimilation.u003cstrongu003eu003cemu003eCredits: Atieh Alipour / Courtesy of Peyman Abbaszadehu003c/emu003eu003c/strongu003e Editor’s Note: A revised version of this story was posted on February 17, 2023, to include the interviewee’s updated description of his work responsibilities and goals.
Name: Dr. Peyman Abbaszadeh
Title: Science Collaborator
Organization: Hydrological Sciences Laboratory, Sciences and Exploration Directorate (Code 617)
What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
I work with researchers at Goddard on developing a new generation of hydrologic data assimilation systems by integrating the NASA LIS (Land Information Systems) and ParFlow hydrologic model. My role at Goddard is especially interesting because I get to work with a team of researchers from all over to collaborate on this project. Our goal is to understand the interaction between the land surface and subsurface hydrologic processes and how this complex system is affected by human activities and the environment at different spatial and temporal scales. It is very exciting working closely with outstanding scientists at NASA on solving unknown problems. This is a great opportunity, and I am so excited about that.
Providing access to the information we generate empowers others in the scientific community to use it in their own field studies. Like a recipe, we post all our models and analyses on GitHub with instructions, so that users can utilize them efficiently.
What is your background?
I got my bachelor’s in civil engineering at the University of Tabriz in Iran. Later I moved to Tehran to study hydrology at Tehran Polytechnic University. Later I moved to Tuscaloosa, Alabama, where I got my Ph.D. in water resources at the University of Alabama. Currently, I am continuing my postdoctoral research at Princeton University and reside in New Jersey.
Dr. Peyman Abbaszadeh, a science collaboration researcher at Goddard, discusses the importance of uncertainty in hydrologic studies with high school students in the Water and Climate Academy Week at Watershed Institute, Hopewell Township, New Jersey.u003cstrongu003eu003cemu003eCredits: Lisa Gallagher / Courtesy of Peyman Abbaszadehu003c/emu003eu003c/strongu003e Can you explain how these hydrologic models function?
Hydrologic models simplify the Earth’s surface and subsurface physical processes using a combination of mathematical equations. They are built to predict and estimate the ways in which water flows above and below the surface of the Earth. Knowing this is extremely important as it helps us to better manage water resources and irrigation systems in different locations with different hydroclimate regimes. Hydrologic models are utilized to enhance drought monitoring, flood forecasting, and other early warning systems by providing more accurate and reliable estimates of soil moisture, evapotranspiration, surface runoff, and subsurface water flow among others.
Why did you become a hydrology focused scientist?
I became a hydrologist to study how much water we have access to on Earth and how it moves and stores in the atmosphere, on the land surface, and below the ground while being affected by climate change. Along with conducting research, one of my top priorities is making sure that my research contributes to the education of younger generations. To achieve this, I am so happy that I got the chance to get involved in the outreach and education program at the IGWMC (Integrated GroundWater Modeling Center) at Princeton University, where we promote the education of K-12 students and teachers, as well as community members.
Can you explain why hydrological science is significant to current research?
As we know, climate change is now a climate crisis, as it is warming our planet and disturbing the water cycle by changing the hydrologic processes on the land surface and below the ground. Understanding how the hydrologic variables and fluxes — for example, soil moisture, evapotranspiration, river flow, and groundwater — change over time and interact helps us better prepare and plan for current conditions and accurately forecast future events, such as floods, droughts, wildfires, and heatwaves. These extreme events cause billions of dollars in damage annually in the US and globally. Hydrologic science contributes to a better understanding of the physics behind these processes and their interactions and paves the way for better estimating the likelihood of future events.
What inspires you?
I decided to apply for this position because during my Ph.D. study, there was a constant voice in the back of my head asking how I could apply the skills I had learned and contribute to society. I wanted to reapply my knowledge in the field to help solve real-world water-related problems and challenges. Working on this project helps me see the real footprint of my research.
What do you like to do in your free time?
I love to travel with my wife. Recently we had the opportunity to visit Vermont and New Hampshire, which have beautiful scenery. I also love hiking, so this recent trip was a blast!
How do you relax after a long day spent in the lab?
Card games are another passion of mine, particularly a good poker night. But it’s not a complete end of the day without a good TV show to unwind.

u0022The really interesting thing to me is how time theoretically acts strangely around black holes. According to Albert Einstein’s theory of gravity, black holes change the flow of time,u0022 said Jeremy Schnittman, Goddard research astrophysicist. u0022So much of how we experience the world is based on time, time marching steadily forward. Anything that changes that is a fascinating take on reality.u0022u003cstrongu003eu003cemu003eCredits: NASA’s Goddard Space Flight Center / Rebecca Rothu003c/emu003eu003c/strongu003e Name: Jeremy Schnittman
Formal Job Classification: Research astrophysicist
Organization: Gravitational Astrophysics Laboratory, Astrophysics Division (Code 663)
What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?
I try to understand the formation and properties of black holes. I also help develop ideas for new missions to study black holes.
What drew you to astrophysics?
I always liked science and math. The great thing about astrophysics is that it involves a little bit of everything – math, computer programming, physics, chemistry and even philosophy to understand the big picture, the enormity of space.
I have a B.A. in physics from Harvard, and a Ph.D. in physics from MIT. I came to Goddard in 2010 after two post-doctoral fellowships.
Explore how the extreme gravity of two orbiting supermassive black holes distorts our view. In this visualization, disks of bright, hot, churning gas encircle both black holes, shown in red and blue to better track the light source. The red disk orbits the larger black hole, which weighs 200 million times the mass of our Sun, while its smaller blue companion weighs half as much. Zooming into each black hole reveals multiple, increasingly warped images of its partner. Watch to learn more.

Download high-resolution video and images from NASA’s Scientific Visualization Studio As an astrophysicist, what do you think about?
I think of myself as a computational physicist as opposed to an experimental or observational physicist. I write many computer programs to do computer simulations of black holes. I also do a lot of theoretical physics, which is pencil and paper work. I think a lot about equations and math to understand black holes.
What is most philosophical about black holes to me is not so much what people most often think about, that their gravity is so strong that even light cannot escape. The really interesting thing to me is how time theoretically acts strangely around black holes. According to Albert Einstein’s theory of gravity, black holes change the flow of time. If you could get close enough to a black hole, theoretically you could go back and forth in time. All our experiments and observations seem to indicate that is how black holes might behave.
So much of how we experience the world is based on time, time marching steadily forward. Anything that changes that is a fascinating take on reality.
Related Link: Gravity Assist: Black Hole Mysteries, with Jeremy Schnittman What do you tell the people you mentor?
I mentor undergraduate, graduate, and post graduate students in astrophysics. Since we are working remotely, I have students from all over the country. I help them with their research projects which mostly relate to black holes in some way. I also offer career advice and help them with their work-life balance. When possible, family comes first.
There are more people coming out of graduate school in astrophysics than there are jobs, so there are going to be many people who will not work for NASA or as a professor. Fortunately, there are a lot of other fascinating, related jobs, and I help guide the students there.
What do you do for fun?
I have a woodshop in our basement where I build furniture, dollhouses, toys, and other items for gifts. As a theoretical physicist, I don’t get to work in a lab. So it is nice to have some hands on experience.
I do a lot of hiking and cycling to exercise. I also enjoy spending time with my family.
Who is your favorite author?
Andy Weir is probably my favorite sci-fi author. I also love the epic naval historical fiction by Patrick O’Brian.
Who inspires you?
My childhood hero, who is still my scientific hero, is Albert Einstein. The more I work in astrophysics, the more he impresses me. Every single one of his predictions that we have been able to test has proven true. It may be a while, but someday I hope we prove his theories about time travel.
Also, I admire Kip Thorne, an American physicist from Cal Tech and recent Nobel laureate, who is “the man” when it comes to black holes. He is also a really nice, good guy, a real mensch. Very humble and down-to-earth. He is always extremely patient, kind and encouraging especially to the younger scientists. He is a good role model as I transition from junior to more senior status.
What is your one big dream?
I make a lot of predictions, so it would be exciting if one of my theories was proven correct. Hopefully someday.
