Credits: NASA/Josh Litofsky NASA’s Artemis campaign aims to return humans to the Moon, develop a sustainable presence there, and lay the groundwork for the first crewed missions to Mars. As the agency prepares for longer stays on and around the Moon, engineers are working diligently to understand the complex behavior of lunar dust, the sharp, jagged particles that can cling to spacesuits and jam equipment.
Lunar dust has posed a problem since astronauts first encountered it during the Apollo missions. Ahead of more frequent and intense contact with dust, NASA is developing new strategies to protect equipment as astronauts travel between the Moon and spacecraft like Gateway, humanity’s first lunar space station.
Josh Litofsky, systems engineer at NASA’s Johnson Space Center, scoops material designed to behave like lunar dust to test how it adheres to Gateway materials. NASA/Bill Stafford Unlike Apollo-era spacecraft that faced lunar dust exposure just once, Gateway will encounter it each time a Human Landing System spacecraft returns to the space station from the lunar South Pole region. Dust could enter Gateway’s environment, risking damage to science instruments, solar arrays, robotic systems, and other important hardware.
Josh Litofsky is the principal investigator and project manager leading a Gateway lunar dust adhesion testing campaign at NASA’s Johnson Space Center in Houston. His team tracks how the dust interacts with materials used to build Gateway.

NASA/Alberto Bertolin “The particles are jagged from millions of years of micrometeoroid impacts, sticky due to chemical and electrical forces, and extremely small,” Litofsky said. “Even small amounts of lunar dust can have a big impact on equipment and systems.”
Litofksy’s work seeks to validate the Gateway On-orbit Lunar Dust Modeling and Analysis Program (GOLDMAP), developed by Ronald Lee, also of Johnson Space Center. By considering factors such as the design and configuration of the space station, the materials used, and the unique conditions in lunar orbit, GOLDMAP helps predict how dust may move and settle on Gateway’s external surfaces.

NASA/Bill StaffordNASA/Bill Stafford Early GOLDMAP simulations have shown that lunar dust can form clouds around Gateway, with larger particles sticking to surfaces.
The data from these tests and simulations will help NASA safeguard Gateway, to ensure the space station’s longevity during the next era of lunar exploration.
The lessons learned managing lunar dust and other harsh conditions through Gateway and Artemis will prepare NASA and its international partners for missions deeper into the cosmos

Credit: NASA With Finland’s signing of the Artemis Accords on Tuesday, NASA celebrates the 53rd nation committing to the safe and responsible exploration of space that benefits humanity. The signing ceremony took place on the margins of the Aalto University’s Winter Satellite Workshop 2025 in Espoo, Finland.
“Today, Finland is joining a community of nations that want to share scientific data freely, operate safely, and preserve the space environment for the Artemis Generation,” said NASA Associate Administrator Jim Free, who provided pre-recorded virtual remarks for the ceremony. “By signing the Artemis Accords, Finland builds on its rich history in space, excelling in science, navigation, and Earth observation. Forging strong partnerships between our nations and among the international community is critical for advancing our shared space exploration goals.”
Wille Rydman, Finland’s minister of economic affairs, signed the Artemis Accords in front of an audience of Finnish space officials and workshop attendees.
“Finland has been part of the space exploration community for decades with innovations and technology produced by Finnish companies and research institutions,” said Rydman. “The signing of the Artemis Accords is in line with Finland’s newly updated space strategy that highlights the importance of international cooperation and of strengthening partnerships with the Unites States and other allies. We aim for this cooperation to open great opportunities for the Finnish space sector in the new era of space exploration and in the Artemis program.”
NASA and Finland have a long history of collaboration, and most recently, Finland is contributing to the upcoming Intuitive Machines-2 delivery to the Moon under NASA’s Artemis campaign and CLPS (Commercial Lunar Payload Services) initiative. Intuitive Machines will deliver a lunar LTE/4G communications system developed by Finnish company, Nokia. Its U.S. subsidiary, Nokia of America, was selected as part of NASA’s Tipping Point opportunity through the agency’s Space Technology Mission Directorate, to advance a lunar surface communications system that could help humans and robots explore more of the Moon than ever before.
The Finnish Meteorological Institute also provided the pressure and humidity measurement instruments for the Environmental Monitoring Station instrument suite aboard the Curiosity Rover, operating on Mars now.
In 2020, the United States, led by NASA and the U.S. Department of State, and seven other initial signatory nations established the Artemis Accords, a set of principles promoting the beneficial use of space for humanity.
The Artemis Accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices for responsible behavior that NASA and its partners have supported, including the public release of scientific data.

Teams with NASA are gaining momentum as work progresses toward future lunar missions for the benefit of humanity as numerous flight hardware shipments from across the world arrived at the agency’s Kennedy Space Center in Florida for the first crewed Artemis flight test and follow-on lunar missions. The skyline at Kennedy will soon see added structures as teams build up the ground systems needed to support them.
Crews are well underway with parallel preparations for the Artemis II flight, as well as buildup of NASA’s mobile launcher 2 tower for use during the launch of the SLS (Space Launch System) Block 1B rocket, beginning with the Artemis IV mission. This version of NASA’s rocket will use a more powerful upper stage to launch with crew and more cargo on lunar missions. Technicians have begun upper stage umbilical connections testing that will help supply fuel and other commodities to the rocket while at the launch pad.
In summer 2024, technicians from NASA and contractor Bechtel National, Inc. completed a milestone called jack and set, where the center’s mega-mover, the crawler transporter, repositioned the initial steel base assembly for mobile launcher 2 from temporary construction shoring to its six permanent pedestals near the Kennedy’s Vehicle Assembly Building.
Teams at Bechtel National, Inc. use a crane to lift Module 4 into place atop the mobile launcher 2 tower chair at its park site on Jan. 3, 2025, at Kennedy Space Center in Florida. Module 4 is the first of seven modules that will be stacked vertically to make up the almost 400-foot launch tower that will be used beginning with the Artemis IV mission.Betchel National Inc./Allison Sijgers “The NASA Bechtel mobile launcher 2 team is ahead of schedule and gaining momentum by the day,” stated Darrell Foster, ground systems integration manager, NASA’s Exploration Ground Systems Program at NASA Kennedy. “In parallel to all of the progress at our main build site, the remaining tower modules are assembled and outfitted at a second construction site on center.”
As construction of the mobile launcher 2’s base continues, the assembly operations shift into integration of the modules that will make up the tower. In mid-October 2024, crews completed installation of the chair, named for its resemblance to a giant seat. The chair serves as the interface between the base deck and the vertical modules which are the components that will make up the tower, and stands at 80-feet-tall.
In December 2024, teams completed the rig and set Module 4 operation where the first of a total of seven 40-foot-tall modules was stacked on top of the chair. Becthel crews rigged the module to a heavy lift crane, raised the module more than 150-feet, and secured the four corners to the tower chair. Once complete, the entire mobile launcher structure will reach a height of nearly 400 feet – approximately the length of four Olympic-sized swimming pools placed end-to-end.
On the opposite side of the center, test teams at the Launch Equipment Test Facility are testing the new umbilical interfaces, which will be located on mobile launcher 2, that will be needed to support the new SLS Block 1B Exploration Upper Stage. The umbilicals are connecting lines that provide fuel, oxidizer, pneumatic pressure, instrumentation, and electrical connections from the mobile launcher to the upper stage and other elements of SLS and NASA’s Orion spacecraft.
“All ambient temperature testing has been successfully completed and the team is now beginning cryogenic testing, where liquid nitrogen and liquid hydrogen will flow through the umbilicals to verify acceptable performance,” stated Kevin Jumper, lab manager, NASA Launch Equipment Test Facility at Kennedy. “The Exploration Upper Stage umbilical team has made significant progress on check-out and verification testing of the mobile launcher 2 umbilicals.”

The new umbilical interface will be used beginning with the Artemis IV mission. Credit: LASSO Contract LETF Video Group The testing includes extension and retraction of the Exploration Upper Stage umbilical arms that will be installed on mobile launcher 2. The test team remotely triggers the umbilical arms to retract, ensuring the ground and flight umbilical plates separate as expected, simulating the operation that will be performed at lift off.

By NASA
To put boots on the Moon—and keep them there—will require bold thinkers ready to tackle the challenges of tomorrow.
That’s why NASA’s Office of STEM Engagement at Johnson Space Center in Houston is on a mission to empower the next generation of explorers in science, technology, engineering, and mathematics (STEM).
Through the High School Aerospace Scholars (HAS) program, Texas juniors have the opportunity to immerse themselves in space exploration through interactive learning experiences.
“HAS is such an important program because we introduce students to the multitude of careers and experiences that contribute to space exploration,” said NASA HAS Activity Manager Jakarda Varnado. “We go beyond asking students who they want to be when they grow up and ask what problems they want to solve.”
Meet Former HAS Student Madeline King
Madeline King always knew she wanted a career in STEM, with a dream of working at NASA influencing her decision to pursue a degree in Engineering.
Before joining HAS, King thought scientists mainly worked in labs and engineers focused on design. But the HAS program revealed a different reality—scientists and engineers often collaborated on interdisciplinary projects, sometimes even sharing roles.
Official portrait of Madeline King.NASA The program broadened King’s perspective on the diverse paths a STEM degree can lead to. It showed her that careers at NASA offer opportunities across various fields and disciplines.
King said participating in HAS helped to strengthen her problem-solving skills and ability to think creatively. The program required students to tackle complex technical tasks independently, emphasizing self-directed learning. King describes HAS as fun, challenging, and engaging, which helped her excel in technical roles.
“Learning to digest and internalize this information is a skill I continue to use when getting up to speed in new groups or taking on projects outside my current skill set,” said King.
Though King joined HAS during COVID-19, which limited in-person interactions, the experience still made an impact. Her mentors also offered insights into graduate school options, helping her weigh the benefits of advanced degrees against gaining hands-on experience at NASA.
The program opened doors to internships at Johnson in the Engineering Robotics and the Avionics Systems Integration Division. Now, she is studying mechanical engineering at the University of Houston, bringing passion and experience in electronics, robotics, education, project management, and aviation.
“Early on in my internship journey, HAS shined on my resume,” she said. “It demonstrated that I already had experience with NASA’s culture, values, and mission.”
Looking forward, King envisions herself as a flight controller, contributing to both the International Space Station Program and the Artemis campaign. Driven by her passion for NASA’s mission, King is just beginning her journey and is eager to be part of the future of space exploration.
“My internships since HAS have allowed me to make small contributions to both of these missions, and I’m excited to specialize as a full-time engineer,” said King.
Meet Caroline Vergara
As a first-generation student, Caroline Vergara lacked the resources to fully explore her interests in aerospace engineering, let alone envision what that career might look like. That all changed when she was accepted into NASA’s HAS program.
“The exposure to real-world innovation ignited my desire to be part of something bigger, something that pushes the boundaries of human knowledge and capability,” she said.
Caroline Vergara announces the launch of the model rocket she built during her time in the HAS program. NASA/David DeHoyos Touring NASA facilities and watching engineers work on projects opened her eyes to the possibilities in STEM. Today, Vergara is a propulsion design engineering intern at United Launch Alliance, contributing to the Vulcan rocket as a Brooke Owens Fellow.
Vergara initially thought working in STEM was mostly about writing equations or running simulations but HAS showed her it is so much more. “A STEM career is about curiosity, collaboration, and the power to change the world,” she said.
During the program, Vergara joined a team of students to tackle a mission simulation project. They called themselves “Charlie and the Rocket Factory” and designed a prototype rocket together. Working with peers from all over the country showed her the power of diverse perspectives. She experienced firsthand what it was like to be part of a team with a shared vision, working toward something bigger than themselves.
Vergara also discovered her love for 3D printing and computer-aided design through HAS. She spent hours fine-tuning designs, fascinated by the process of turning digital models into physical reality.
Her experience with HAS also sparked a desire to give back. She returned to her hometown to share her story and encourage other students to pursue STEM. Partnering with Johnson Community Engagement Lead Jessica Cordero, she organized video conferences with NASA engineers on International Women in Engineering Day to inspire a new wave of students to be part of space exploration.
“The aerospace industry is entering a new space age, and we have the unique opportunity to put humans back on the Moon and explore beyond,” she said.
Her advice to the Artemis Generation is: “Go for it! You could be part of the generation that changes humanity’s destiny.”
Caroline Vergara, University of Houston Class of 2025. As a mechanical engineering honors student at the University of Houston and chief engineer of Space City Rocketry, Vergara envisions contributing to the Artemis campaign and advancing NASA’s mission to explore the cosmos.
“My dream is to contribute to space exploration efforts that put humans back on the Moon and beyond, and to one day work in Mission Control Center, where I can help guide those historic missions into the future.”
Meet Iker Aguirre
For Iker Aguirre, the spark that ignited his journey toward a career in aerospace was lit by a passing conversation during his freshman year of high school. A senior classmate described the HAS program as a once-in-a-lifetime experience that cemented his passion for aerospace. That moment stayed with Aguirre, and when the opportunity arose, he did not hesitate to apply.
Iker Aguirre inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. “HAS showed me that in order to accomplish something as complex as Artemis, you need a well-rounded set of teams and individuals,” he said. “You don’t need to study aerospace to be in the aerospace industry!”
In 2020, Aguirre participated during the remote-only version of HAS, but he recalls that the program still gave him a much deeper understanding of the spaceflight industry.
Despite already being interested in aerospace, Aguirre says HAS broadened his horizons, showing him the diverse pathways into the field. Through collaborative projects with peers across Texas, he discovered that solving the challenges of space exploration requires more than just aerospace engineers.
The program’s emphasis on teamwork left a lasting impression. During his time with HAS, Aguirre found himself working alongside students from different backgrounds, each bringing unique perspectives to problem-solving. It introduced him to dedicated and passionate people with various personalities and cultures who all shared similar dreams and aspirations as him.
Aguirre credits HAS with not only refining his technical skills but also shaping his approach to innovation and teamwork. That experience paid off as he moved through his academic and professional journey, including Pathways program internships with NASA’s Johnson Space Center in Houston and Marshall Space Flight Center in Huntsville, Alabama.
“Getting connections at NASA through HAS helped me open many doors so far,” said Aguirre. “I met many good friends through HAS and my internship at Johnson, which I value to this day.”
Now pursuing a degree in rocket propulsion, with a focus on turbomachinery design, Aguirre remains committed to advancing space exploration. He hopes to contribute to humanity’s mobility in space, tackling challenges in rocket engine feed systems.
