Lunar dust may seem unimposing, but it presents a significant challenge for space missions. Its abrasive and jagged particles can damage equipment, clog devices, and even pose health risks to astronauts. This project addresses such issues by developing advanced coatings composed of crumpled nano-balls made from atomically thin 2D materials such as MoS₂, graphene, and MXenes. By crumpling these nanosheets—much like crumpling a piece of paper—we create compression and aggregation resistant particles that can be dispersed in sprayable solutions. As a thin film coating, these crumpled nano-balls form corrugated structures that passively reduce dust adhesion and surface wear. The deformable crumpled nano-ball (DCN) coating works by minimizing the contact area between lunar dust and surfaces, thanks to its unique nano-engineered design. The 2D materials exhibit exceptional durability, withstanding extreme thermal and vacuum environments, as well as resisting radiation damage. Additionally, the flexoelectric and electrostatically dissipative properties of MoS₂, graphene, and MXenes allow the coating to neutralize and dissipate electrical charges, making them highly responsive to the charged lunar dust environment. The project will be executed in three phases, each designed to bring the technology closer to real-world space applications. First, we will synthesize the crumpled nano-balls and investigate their adhesion properties using advanced microscopy techniques. The second phase will focus on fundamental testing in simulated lunar environments, where the coating will be exposed to extreme temperatures, vacuum, radiation, and abrasion. Finally, the third phase will involve applying the coating to space-heritage materials and conducting comprehensive testing in a simulated lunar environment, targeting up to 90% dust clearance and verifying durability over repeated cycles of dust exposure. This research aligns with NASA’s goals for safer, more sustainable lunar missions by reducing maintenance requirements and extending equipment lifespan. Moreover, the potential applications extend beyond space exploration, with the technology offering promising advances in terrestrial industries such as aerospace and electronics by providing ultra-durable, wear-resistant surfaces. Ultimately, the project contributes to advancing materials science and paving the way for NASA’s long-term vision of sustainable space exploration.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Aerostar Thunderhead balloon carries the STRATO payload into the sky to reach the stratosphere for flight testing. The balloon appears deflated because it will expand as it rises to higher altitudes where pressures are lower.Credit: Colorado Division of Fire Prevention and Control Center of Excellence for Advanced Technology Aerial Firefighting/Austin Buttlar NASA is participating in a collaborative effort to use high-altitude balloons to improve real-time communications among firefighters battling wildland fires.
The rugged and often remote locations where wildland fires burn mean cell phone service is often limited, making communication between firefighters and command posts difficult.
The flight testing of the Strategic Tactical Radio and Tactical Overwatch (STRATO) technology brought together experts from NASA’s Ames Research Center in California’s Silicon Valley, the U.S. Forest Service, high-altitude balloon company Aerostar, and Motorola to provide cell service from above. The effort was funded by the NASA Science Mission Directorate’s Earth Science Division Airborne Science Program and the agency’s Space Technology Mission Directorate Flight Opportunities program.
“This project leverages NASA expertise to address real problems,” said Don Sullivan, principal investigator for STRATO at NASA Ames. “We do a lot of experimental, forward-thinking work, but this is something that is operational and can make an immediate impact.”
Flying High Above Wildland Fires
Soaring above Earth at altitudes of 50,000 feet or more, Aerostar’s Thunderhead high-altitude balloon systems can stay in operation for several months and can be directed to “station keep,” staying within a radius of few miles. Because wildland fires often burn in remote, rugged areas, firefighting takes place in areas where cell service is not ideal. Providing cellular communication from above, from a vehicle that can move as the fire changes, would improve firefighter safety and firefighting efficiency.
The STRATO project’s first test flight took place over the West Mountain Complex fires in Idaho in August and demonstrated significant opportunities to support future firefighting efforts. The balloon was fitted with a cellular LTE transmitter and visual and infrared cameras. To transmit between the balloon’s cell equipment and the wildland fire incident command post, the team used a SpaceX Starlink internet satellite device and Silvus broadband wireless system.
When tested, the onboard instruments provided cell coverage for a 20-mile radius. By placing the transmitter on a gimbal, that cell service coverage could be adjusted as ground crews moved through the region.
The onboard cameras gave fire managers and firefighters on the ground a bird’s-eye view of the fires as they spread and moved, opening the door to increased situational awareness and advanced tracking of firefighting crews. On the ground, teams use an app called Tactical Awareness Kit (TAK) to identify the locations of crew and equipment. Connecting the STRATO equipment to TAK provides real-time location information that can help crews pinpoint how the fire moves and where to direct resources while staying in constant communication.
Soaring Into the Future
The next steps for the STRATO team are to use the August flight test results to prepare for future fire seasons. The team plans to optimize balloon locations as a constellation to maximize coverage and anticipate airflow changes in the stratosphere where the balloons fly. By placing balloons in strategic locations along the airflow path, they can act as replacements to one another as they are carried by airflow streams. The team may also adapt the scientific equipment aboard the balloons to support other wildland fire initiatives at NASA.
As the team prepares for further testing next year, the goal is to keep firefighters informed and in constant communication with each other and their command posts to improve the safety and efficiency of fighting wildland fires.
“Firefighters work incredibly hard saving lives and property over long days of work,” said Sullivan. “I feel honored to be able to do what we can to make their jobs safer and better.”

NASA Energy Program Manager for Facility Projects Wayne Thalasinos, left, stands with NASA Stennis Sustainability Team Lead Alvin Askew at the U.S. Department of Energy in Washington, D.C., on Oct. 30. The previous day, the Department of Energy announced NASA Stennis will receive a $1.95 million grant for an energy conservation project at the south Mississippi center. The Stennis Sustainability Team consists of NASA personnel and contract support. NASA members include Askew, Missy Ferguson and Teenia Perry. Contract members include Jordan McQueen (Synergy-Achieving Consolidated Operations and Maintenance); Michelle Bain (SACOM); Matt Medick (SACOM); Thomas Mitchell (SACOM); Lincoln Gros (SACOM), and Erik Tucker (Leidos). NASA Stennis NASA’s Stennis Space Center has been awarded a highly competitive U.S. Department of Energy grant to transform its main administration building into a facility that produces as much renewable energy as it uses.
Following an Oct. 29 announcement, NASA Stennis, located near Bay St. Louis, Mississippi, will receive $1.95 million through the Assisting Federal Facilities with Energy Conservation Technologies (AFFECT) Program. The grant will fund installation of a four-acre solar panel array onsite that can generate up to 1 megawatt of electricity.
“This is a flagship project for our NASA center,” said NASA Stennis Director John Bailey. “It will provide renewable energy to help reduce our carbon footprint, contributing to NASA’s agencywide goal of zero greenhouse gas emissions by 2030.”
The AFFECT Program awards grants to help the federal government achieve its goal of net-zero greenhouse gas emissions by all federal buildings by 2045. More than $1 billion in funding proposals was requested by federal agencies for the second, and final, phase of the initiative. A total of $149.87 million subsequently was awarded for 67 energy conservation and clean energy projects at federal facilities across 28 U.S. states and territories and in six international locations. NASA Stennis is the only agency in Mississippi to receive funding.
The site’s solar panel array will build on an $1.65 million energy conservation project already underway at the south Mississippi site to improve energy efficiency. The solar-generated electricity can be used in a number of ways, from powering facility lighting to running computers. The array also will connect to the electrical grid to allow any excess energy to be utilized elsewhere onsite.
“This solar panel addition will further enhance our energy efficiency,” said NASA Stennis Sustainability Team Lead Alvin Askew. “By locating the solar photovoltaic array by the Emergency Operations Center, it also has potential future benefits in providing backup power to that facility during outages.”
The NASA Stennis proposal was one of several submitted by NASA centers for agency consideration. Following an agency review process, NASA submitted multiple projects to the Department of Energy for grant consideration.
“This was a very competitive process, and I am proud of the NASA Stennis Sustainability Team,” NASA Stennis Center Operations Director Michael Tubbs said. “The team’s hard work in recent years and its commitment to continuous improvement in onsite energy conversation laid the groundwork to qualify for this grant. Mr. Askew, in particular, continues to be a leader in creative thinking, helping us meet agency sustainability goals.”
The NASA Stennis administration building was constructed in 2008 as a Leadership in Energy and Environmental Design-certified, all-electric facility and currently has net-zero emissions.

Dr. Annie Meier (second from left) and her team inside the Applied Chemistry Lab at NASA’s Kennedy Space Center in Florida began supplementing their normal workload in mid-2023 with efforts to improve the lab’s sustainable practices. In 2024, the laboratory became the first at NASA to receive certification from the non-profit My Green Lab for its efforts in sustainability.NASA/Kim Shiflett NASA’s Kennedy Space Center in Florida has a long record of achievements in sustainability and recently added another to the list when the spaceport’s Applied Chemistry Lab became the first in the agency to be certified for its environmentally conscious practices.
The My Green Lab Certification recognizes sustainability best practices in research facilities around the world. The certification program run by My Green Lab, a non-profit dedicated to creating a culture of sustainability through science, is considered a key measure of progress towards a zero-carbon future by the United Nations Race to Zero campaign.
“When I heard our lab achieved certification, I was so happy,” said Dr. Annie Meier, one of the laboratory’s chemical engineers. “It meant we could now make a conscious effort to share these green practices with all who work in our lab. We even added them to our training materials for new and incoming members in the lab.”
The lab performs research and technology development for a wide range of chemistry and engineering-related applications to solve the unique operational needs of NASA and outside partners. The lab primarily focuses on in-situ resource utilization and addressing technology gaps related to lunar and Martian sustainability. The lab’s scientists also provide expertise in the fields of logistics reduction, plasma science, hypergolic fuels, analytical instrumentation, and gas analysis.
While sustainability has long been a focus of the lab, the journey to the certification began when Riley Yager, a doctoral student from University of Alabama at Birmingham – where Meier was a technical monitor – shared her knowledge of the program after pursuing green lab practices at her university.
“I work as a sustainability ambassador at my university, so I knew of this program,” Yager said. “Sustainable practices are something woven into my everyday life, so naturally I wanted to bring those practices into my lab environments.”
After learning about the program from Yager and discovering the many other academic institutions and companies certified globally, Meier submitted a proposal to NASA and obtained funding to pursue certification for the Applied Chemistry Lab.
After a kickoff event hosted by My Green Lab in April 2023, the lab’s path to certification began with a self-assessment survey, in which members of the lab answered a series of questions about their practices in areas such as cold storage, green chemistry, infrastructure energy, resource management, waste reduction, and water. My Green Lab collected and analyzed the answers, providing a baseline assessment and recommendations to improve the lab’s sustainable practices.
“We took their initial survey and learned we had lots of room for improvements as a lab,” Meier said. “Then I worked with a few interns over the summer to spearhead the ‘green team’ to implement changes and get momentum from the entire lab.”
The lab began with minimizing purchases by improving efficiencies during the inventory process. The team also performed a waste audit of all seven of its laboratories. They adopted nitrile glove and pipette tip box recycling, reviewed the “12 principles of green chemistry” with the lab members, and installed stickers and signage about what can and cannot be unplugged to save energy. Additionally, they installed low-flow aerators on the lab tap sinks to reduce flow, and the lab now uses a recycling sink to save on water or solvents for cleaning parts.
As luck would have it, Yager ended up working at the Applied Chemistry Lab on a NASA fellowship and became a member of the green team.
“It was really fun to see that come full circle,” Meier said. “Almost all members of the lab, from our fellows to most senior members, used their self-motivation to get on the sustainability train.”
The green team continued to grow as the lab implemented changes to become more sustainable. Just over six months after the kickoff event, they completed another assessment survey. With possible certification levels of bronze, silver, gold, platinum, and green – the level that adheres closest to My Green Lab’s highest standards – the ACL was certified green, marking the first time any NASA center obtained a My Green Lab Certification.
“Our lab is looking to sustain these green practices and achieve the same status when we are reassessed in the future,” Meier said. “This effort could be a wonderful catalyst to inspire other work groups to lean towards more ‘green’ practices at the frontline in our laboratories.”
The NASA Kennedy lab joined over 2,500 labs in a range of sectors that received the My Green Lab certification. Maintaining the distinction will require recertification every two years.
