The science from every Moon rock sample, lunar dataset, and discovery produced through NASA’s Artemis program will be shared by the agency with the global scientific community. That commitment is upheld by all 71 countries that have signed the Artemis Accords, a set of principles for safe and transparent civil space exploration.

NASA put those principles into practice by hosting a two-part virtual workshop series that began July 28 and concluded Sept. 8, focusing on one key tenet of the Artemis Accords: the timely release of scientific data to the public and the international scientific community.

“As we return humans to the Moon, our Artemis efforts will help us unlock the full potential of scientific discovery through transparency, collaboration, and accessibility,” said Jacob Bleacher, chief exploration scientist at NASA. “We are making data, tools, and results freely available, and inviting the Artemis Accords partners to innovate with us and share their data as well, accelerating our understanding of lunar processes and laying the groundwork for human space exploration for the Moon, Mars and beyond.”  

The two recent workshops added to discussions led by the ISRO (Indian Space Research Organisation) in May, when signatories first explored ways to advance open data practices and created common ground for deeper conversations on open data. NASA split its follow‑on discussion about data sharing into two virtual sessions, so technical experts around the world could take part.

The agency hosted its first session on open science principles and implementation practices. It promoted interoperability and collaboration among signatories and advanced reproducibility, accessibility, and transparency in scientific work, including in NASA’s Artemis program.

The second session focused on tools for open science, providing Artemis Accords signatories with a working model to reference as they build or refine their own data-sharing frameworks.

“NASA is committed to leading by example when it comes to open science,” said Andrew Mitchell, deputy chief science data officer for NASA’s Science Mission Directorate, whose office leads the agency’s open science efforts. “These workshops gave our Artemis Accords partners practical tools and a shared foundation to build on as we move forward together.”  

NASA presented the Planetary Data System, one of the agency’s primary archives for planetary science data, openly available lunar data, data visualization and analysis tools, and the system’s data information model standard, offering a real-world example of how NASA structures, curates, and shares scientific data with the world.

Across both sessions, NASA shared practices developed over years of stewarding scientific data and opened the floor to technical experts across the Artemis Accords community, reflecting a deliberate effort to build alignment at the working level.

“Advances in technology help enable open science, but technology alone is insufficient,” said Mitchell. “Open science requires a shift to a more transparent and collaborative scientific process, which will increase the pace and quality of scientific progress. Scientific processes and results should be as open and repeatable as possible to encourage further study.”

In 2020, NASA and the State Department joined with seven other founding nations to establish the Artemis Accords in response to the growing interest in lunar activities by both governments and private companies. They introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars, and beyond, committing nations to:

• explore peaceably and transparently
• render aid to those in need
• enable access to scientific data
• ensure activities do not interfere with those of others
• preserve historically significant sites and artifacts by developing best practices

By signing the Artemis Accords, nations open the door to opportunities for future lunar exploration with NASA, advancing humanity’s return to the Moon, and shaping the Golden Age of space exploration and innovation.

During a ceremony hosted by NASA Administrator Jared Isaacman at the agency’s headquarters in Washington on Monday, the Republic of Türkiye signed the Artemis Accords, joining the growing international coalition of like-minded nations dedicated to peaceful, transparent space exploration.

“It is my privilege to welcome the Republic of Türkiye as the 71st signatory of the Artemis Accords,” said Isaacman. “Last year, President Trump directed NASA to accelerate its return to the lunar surface and establish humanity’s first enduring presence on another world, a Moon Base, as well as lay the foundation for the manned exploration of Mars. NASA never undertakes these grand endeavors alone. On the Moon Base, we’re taking the Artemis Accords principles and putting them into practice on the lunar surface. NASA has invited every signatory to take part in this endeavor, creating opportunities for nations to contribute major pieces of hardware, scientific payloads, technology demonstrations, CubeSats, and other capabilities to future Artemis missions.”

Turkish Minister of Industry and Technology Mehmet Fatih Kacır signed on behalf of Türkiye. The President of the Turkish Space Agency Yusuf Kıraç, and the U.S. Deputy Assistant Secretary of State for Space and Environment Connor Tomlinson, also participated in the event.

Türkiye’s recent achievements in human spaceflight underscore its commitment to space exploration. In 2024, the country’s first astronaut, Alper Gezervaci, traveled to the International Space Station on Axiom Mission 3 and conducted scientific research alongside NASA astronauts. That same year, a second Turkish astronaut, Tuva Atasever, flew on Virgin Galactic 07 suborbital mission, conducting experiments and physiology research.

Türkiye will soon launch its first lunar mission, AYAP-1, joining the small but growing group of countries building and launching their own satellites to the Moon.

The country’s signing also comes as the country prepares to host the International Astronautical Congress in Antalya this October. Dozens of Artemis Accords signatories are expected to attend to discuss the future of peaceful and transparent space exploration.

For the first time in decades, NASA has rolled out one of its iconic astronaut training aircraft with a bold, new look.

The space agency debuted a new livery on one of its T-38 jets in celebration of its program to return astronauts to the Moon. The Artemis design retains nods to what made the "white rocket" immediately recognizable, but adds a new colorway and painted graphics to make clear where NASA is headed.

"This new 'Artemis' livery has a black and white paint scheme with blue and red stripes that separate those two paint schemes," said Sean Brady, who proposed and designed the new livery while serving as the T-38 project pilot in NASA's Aircraft Operations Division (AOD), part of the Flight Operations Directorate at Johnson Space Center in Houston. "The Artemis program logo in the back and a picture of the Moon is on the left and right side of the rear fuselage."

EDITOR’S NOTE: This story, originally published in December, was revised Aug. 26, 2026 with an update on a new phase of testing, including video from a recent test run and new images.

To help NASA and commercial partners better understand the science of lunar landings, specifically the hazards that may occur when a lander’s engine plumes blast away at lunar dust, soil, and rocks, a team at NASA’s Langley Research Center in Hampton, Virginia, has initiated a series of plume-surface interaction tests inside a massive 60-foot spherical vacuum chamber.

As NASA works to return humans to the Moon starting with Artemis IV in 2028 and develop a Moon Base, the tests will provide a trove of data for researchers to use to improve predictive models and influence the design of space hardware.

“This plume-surface interaction ground test is the most complex test of its kind to be undertaken in a vacuum chamber,” said Ashley Korzun, testing lead at NASA Langley. “If I’m in a spacecraft and I’m going to move all that regolith while landing, some of that’s going to hit my lander. Some of it’s going to go out toward other things — payloads, science experiments, eventually rovers and other assets. Understanding those physics is pivotal to ensuring crew safety and mission success.”

The campaign involves multiple NASA centers, academic institutions, and commercial entities both small and large.

Korzun’ s team will test two types of propulsion systems in the vacuum sphere. For the first round of tests, they are using an ethane plume simulation system designed by NASA’s Stennis Space Center near Bay St. Louis, Mississippi, and built and operated by Purdue University. The ethane system generates a maximum of about 100 pounds of thrust — imagine the force necessary to lift or support a 100-pound person. It heats up but doesn’t burn.

The team recently began firing the system into a roughly six-and-a-half-foot diameter, one-foot-deep bin of simulated lunar regolith, called Black Point-1, that has jagged, cohesive properties similar to actual lunar regolith.

A number of different instruments, including a version of the Stereo Cameras for Lunar Plume Surface Studies system that imaged the plume-surface interaction when Firefly’s Blue Ghost Mission-1 landed on the Moon in 2025, are capturing data and imagery from the tests, which will only last about six seconds each. The instruments are measuring things such as crater formation, angle and height of the ejecta sheet, spatial distribution of solid ejecta, and the speed of the regolith particles as they get blasted out of the bin.

Later this year, a second round of tests will involve a 14-inch, 3D-printed hybrid rocket motor developed at Utah State University in Logan, Utah, and tested at NASA’s Marshall Space Flight Center in Huntsville, Alabama. It produces around 35 pounds of thrust, igniting both solid propellant and a stream of gaseous oxygen to create a hot, powerful stream of rocket exhaust, simulating a real rocket engine but at smaller scale for this test series.
Researchers will test both propulsion systems at various heights.

“It gives us a huge range of test conditions,” Korzun said, “to be able to talk about spacecraft of all different kinds going to the Moon, and for us to understand what they’re going to do as they land or try to take back off from the surface.”

Korzun sees this test campaign as more than a one-shot, Moon-specific thing. The entire operation is modular by design and also can prepare NASA for missions to Mars. The lunar regolith simulant can be replaced with a Mars simulant that’s more like sand. Pieces of hardware and instrumentation can be unbolted and replaced to represent future Mars landers. Rather than take the vacuum sphere down to really low pressure like on the Moon, it can be adjusted to a pressure that simulates the atmosphere on the Red Planet.

“Mars has always been in our road maps,” Korzun said.

But for now, the Moon looms large.

“This test campaign is one of the most flight-relevant and highly instrumented plume-surface interaction test series NASA has ever conducted,” said Daniel Stubbs, an engineer with the Human Landing Systems plume and aero environments team at NASA Marshall. “The data from these tests at NASA Langley will be critical in developing and validating models to predict the effects of plume-surface interaction for landing on the Moon and even Mars, ensuring mission success for the human landing systems and the safety of our astronauts.”

Through the Artemis program, NASA will send astronauts on increasingly complex missions to explore the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and to build on our foundation for the first crewed missions to Mars.

NASA’s 737 aircraft was painted this week in Oklahoma as it progresses with modifications for use as a reduced gravity test aircraft for the agency. NASA’s Armstrong Flight Research Center in Edwards, California, took ownership of the aircraft from the United States Air Force in June. 

The aircraft will perform lunar-gravity parabolic flights to validate astronaut lunar suits and associated crew systems required to support Artemis mission objectives. These flights will happen at NASA’s Johnson Space Center in Houston for reduced-gravity operations, with NASA Armstrong oversight.

In addition, the aircraft will serve as a key asset for systems‑integration research for flight testing autonomy, sensors, and other digital systems.

As a young girl raised in Worcester, Massachusetts, Lindsey Waitt dreamed of working for NASA. Her dream is now a reality as she embarks on her role as a NASA test project engineer with the Artemis launch team – an integral part of the agency’s missions that will enable humans to return to the surface of the Moon after launching from NASA’s Kennedy Space Center in Florida.

When she was in middle school in the late 1990’s, Waitt recalls meeting NASA Space Shuttle astronauts Michael Lopez-Alegria and Albert Sacco, Jr., a former professor at the college, during a visit to Worcester Polytechnic Institute (WPI) in Worcester, Massachusetts. She was inspired while listening to them recount their spaceflight experiences including an experiment on conducting research for growing cells on the Moon. She even posed for a picture and got their autographs. Little did young Waitt know, these would not be the only astronauts she would meet.

Her passion for learning about all things space and engineering led Waitt back to WPI where she studied engineering, absorbing different disciplines. She received her Bachelor of Science degree in Mechanical Engineering with a concentration in aerospace engineering and she left the school fueled by her passion to be a part of America’s space agency.

After graduation, she worked as a systems engineer on radar flight test missions for a defense contractor, and while excelling in her role, she realized it wasn’t the aerospace engineering field that she desired.

“It was an exciting program, and it was meaningful to be a part of a project focused on protecting the country from enemy attacks. But it wasn’t space,” Waitt said.

As the wife of a now retired sergeant first class officer in the United States Army, Waitt and her family traveled around the world during her husband’s enlistment, and she continued to follow NASA missions from around the globe. While Waitt was dedicated to raising her three young boys, she simultaneously pursued her master’s degree in Space Operations from the University of Colorado in Colorado Springs. Twelve years later, she made the courageous decision to fully return to her first career passion – working for NASA – despite nay-sayers suggesting too much time had passed for her to return to the industry.

Waitt vividly remembers watching NASA astronauts Doug Hurley and Bob Behnken soar skyward during NASA’s first commercial crew mission to the International Space Station in 2020. Watching alongside her family, she even set up a rocket-shaped tent, and she and her children pretended to blast off from their yard as they cheered excitedly as the astronauts lifted off from what would be her future place of work.

After moving to Florida in 2022 to work at a small satellite company in Cape Canaveral, as a systems engineer and program manager, she continued to search for opportunities to work for the agency. Waitt vividly remembers watching Artemis I with her family. They had just moved to the Sunshine State, and she woke up in the early hours of the morning to watch the historic launch, having no idea she would be working on the next Artemis mission – the first time NASA sent humans around the Moon in over 50 years!

In 2024, Waitt began her career at Kennedy working for a contractor as a test project engineer during the Artemis II launch. As “problem-solvers,” test project engineers are the main hub of experts for technical tests and launch activities and they work to coordinate resolutions across the different subsystems that may arise during the dynamic operations associated with a rocket launch. Leading up to the Artemis II launch in April, Waitt quickly became certified to sit on the launch console during the dynamic pre and post-launch operations for the massive SLS (Space Launch System) rocket and Orion spacecraft and she eagerly watched from outside Kennedy’s Launch Control Center as the four crew members lifted off the launch pad towards the Moon.

When NASA announced its insourcing initiative earlier this year, Waitt seized the opportunity to fully realize her dream. She applied for a position and is now a NASA civil servant supporting the Artemis launch team as a test project engineer for NASA– a core position for the agency’s launch team. With Artemis III in front of her, Lindsey will see the buildup of launch operations from start to finish.

As the only female of the 14 test project engineers who work on the Artemis launch team, Waitt said she was fully embraced by the colleagues she stands beside.

“Everybody’s very open and welcoming,” Waitt said. “I’ve worked on teams before, but it’s never been like this. Everyone is so passionate about the mission, and everybody is working together to get things done quickly, but safely – that’s always first priority.  We Are Going.”

This opportunity didn’t happen by chance. Waitt is embracing life’s journey and focused on making her dream come true, one launch at a time. “The sky is not the limit – it’s wide open now,” Waitt said. “The universe is the limit.”

NASA has declared “wrenches down” on the first completed payload designed for Artemis astronauts to deploy on the Moon’s surface. Engineers working on NASA’s Lunar Environment Monitoring Station, or LEMS, have completed hardware development and testing and the payload is ready for its permanent home near the lunar South Pole. With the hardware complete, LEMS is ready to support one of the Artemis program’s core goals: enabling sustained lunar science and exploration.

The LEMS instrument package contains two highly sensitive seismometers that will monitor ground vibrations from moonquakes and meteorite impacts, providing scientists with insights into the Moon’s interior and the seismic hazards astronauts might encounter at the surface. Its modular design allows the system to be adapted or expanded to host new instruments in the future, creating a reusable platform that can evolve as scientific priorities grow.

The payload will remain in a clean room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where it was built, until it is assigned to an Artemis mission for deployment to the lunar surface.

“The completion of the LEMS scientific instrument is a major step in a new era of lunar surface science. Innovative science experiments will uncover, measure, and reveal the Moon’s secrets while astronauts open new frontiers for discovery,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “And, behind the scenes, countless teams across NASA and our partners are pushing the boundaries of what surface instruments can do, building the tools that will make future exploration possible and safer.”

The LEMS payload builds on a legacy of lunar seismic tracking. Apollo astronauts deployed a network of seismometers on the Moon’s nearside equatorial region between 1969 and 1972. Those instruments operated until 1977, recording about 13,000 moonquakes and other ground vibrations that helped scientists begin to understand the composition of the Moon’s interior. For decades, researchers have hoped to spread more seismometers, updated with new technologies, across the lunar surface.

Now, LEMS will carry the first seismometers to be deployed by future astronauts to listen for faint ground vibrations, collecting new clues to the Moon’s internal structure and ongoing seismic activity. The sensors will be the most compact, sensitive, and energy-efficient seismometers ever built for planetary exploration.

LEMS itself is about the size of a small suitcase, weighing 11 pounds in the Moon’s low-gravity environment. It will carry not just these seismic sensors, but everything it needs to function independently of humans after deployment. LEMS is built to manage its own power production via a lightweight, flexible solar array that conforms to the shape of the LEMS unit. It also will manage its operational activities to ensure continuous data collection based on a preset plan, and monthly data transmission to Earth. The payload will do all this while maintaining a stable internal temperature throughout the massive day-to-night temperature swings of the South Pole region.

“When we conceived of LEMS, we weren’t just thinking about the next mission, we were thinking about the next generation of lunar exploration,” said Mehdi Benna, a University of Maryland Baltimore County scientist who leads LEMS from NASA Goddard. “Our vision was to create a scientific buoy for the Moon. Like an ocean buoy on Earth, LEMS is designed to be easy to build, adaptable to different scientific objectives, and capable of operating independently for years.”

Before any surface science could happen, Benna and his team had to ensure that LEMS could survive the trip to the Moon and the harsh environment of its surface. Over the past five months, LEMS and its components have been subjected to a demanding series of environmental and operational tests. Engineers verified LEMS can endure the violent shaking of launch, the journey to the lunar surface, and the Moon’s temperature and radiation environment. The team also showed that the instrument package’s mechanical and electrical design is safe for astronaut handling.

The LEMS payload was built to operate through the lunar night, which lasts two Earth weeks, without external power assistance or a heat source. Past lunar surface instruments relied on radioisotope heaters for warmth and power. But LEMS instead will withstand temperatures that dip to minus 400 degrees Fahrenheit in some areas by using advanced insulation materials, low-thermal-conductivity cables that minimize heat loss, and a thermal regulator that conducts heat away during the day to prevent overheating and helps retain heat at night.

These innovations reduce mass and power needs, setting the stage for lighter, energy-efficient instruments that can operate continuously at future Artemis landing sites and the NASA-led Moon Base.

The LEMS payload is led by University of Maryland Baltimore County and University of Maryland College Park. Technical implementation is led by NASA Goddard. The University of Arizona, in partnership with Silicon Audio, Inc., supplied LEMS’ two state-of-the-art seismometers. Morehead State University in Kentucky provided LEMS’ telecommunication system and will operate the instrument on the surface. Washington University in St. Louis will manage the instrument’s data processing and dissemination to the larger scientific community.

As NASA sets its sights on long-term exploration of the Moon and Mars, the agency is increasing the cadence of its Artemis missions. Helping bring these plans to fruition is Tom Percy, manager of systems engineering and integration for NASA’s Human Landing System Program.

Percy serves as a focal point in working with providers SpaceX and Blue Origin to accelerate and streamline systems designs, manufacturing, testing, and certification. He ensures the crewed landers that SpaceX and Blue Origin are developing for Artemis are designed, built, tested, and will operate with other NASA exploration assets safely and effectively.

“You might say that all human landing system integration work lands on my desk. And with the rest of my talented, hard-working systems engineering and integration team, we’re working to make it all happen,” Percy said.

A native of North Easton, Massachusetts, Percy earned a bachelor’s degree in mechanical engineering from the Rochester Institute of Technology in Rochester, New York, where he first got hands-on experience working on designs that could be applied to NASA’s sustainable lunar architecture.

“As an undergrad, I served as president of the Rochester Institute of Technology’s chapter of the American Society of Mechanical Engineers. To get some real-world engineering experience, we decided to participate in the Great Moonbuggy Race,” Percy said. “Now called the Human Exploration Rover Challenge, the competition is held annually at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

“At the time, I had never heard of Marshall Space Flight Center,” said Percy. “But our student team designed and built a rover and traveled to Huntsville for the race. That’s when I learned about some of the projects in Marshall’s diverse portfolio that the center works for NASA. And that’s when I began planning to make my way to NASA Marshall for my career.”

Percy chose to move south and earn a master’s degree in aerospace engineering from the Georgia Institute of Technology in Atlanta. His research in the advanced propulsion lab and courses in space systems design culminated in a spacecraft design course and the chance to work directly with engineers at Marshall.

Since landing at Marshall in 2003, Percy has been involved in evaluating transportation architecture options for human deep space exploration, including missions to land astronauts on the Moon and Mars. He also has expertise in space transportation, including advanced propulsion technology development; trajectory analysis; and spacecraft and mission concept development. Percy earned a doctorate in aerospace systems engineering from the University of Alabama in Huntsville.

The range of experience comes together in his current role as manager of human landing systems engineering and integration.

“The world watched the amazing success of Artemis II. NASA and our commercial providers are looking forward to flying again soon and executing increasingly complex Artemis missions,” Percy said.

Through the Artemis program, NASA will send astronauts on increasingly complex missions to explore more of the Moon for scientific discovery, economic benefits, establish an enduring human presence on the lunar surface, and to build on our foundation for the first crewed missions to Mars.
