MuSat2 at Vandenberg Air Force Base, prior to launch. MuSat2 leverages a dual-frequency science antenna developed with support from NASA to measure phenomena such as ocean wind speed. Muon Space A science antenna developed with support from NASA’s Earth Science Technology Office (ESTO) is now in low-Earth orbit aboard MuSat2, a commercial remote-sensing satellite flown by the aerospace company Muon Space. The dual-frequency science antenna was originally developed as part of the Next Generation GNSS Bistatic Radar Instrument (NGRx). Aboard MuSat2, it will help measure ocean surface wind speed—an essential data point for scientists trying to forecast how severe a burgeoning hurricane will become.
“We’re very interested in adopting this technology and pushing it forward, both from a technology perspective and a product perspective,” said Jonathan Dyer, CEO of Muon.
Using this antenna, MuSat2 will gather signals transmitted by navigation satellites as they scatter off Earth’s surface and back into space. By recording how those scattered navigation signals change as they interact with Earth’s surface, MuSat2 will provide meteorologists with data points they can use to study severe weather.
“We use the standard GPS signals you know—the navigation signals that work for your car and your cell phone,” explained Chris Ruf, director of the University of Michigan Space Institute and principal investigator for NGRx.
Ruf designed the entire NGRx system to be an updated version of the sensors on NASA’s Cyclone Global Navigation Satellite System (CYGNSS), another technology he developed with support from ESTO. Since 2016, data from CYGNSS has been a critical resource for people dedicated to forecasting hurricanes.
The science antenna aboard MuSat2 enables two key improvements to the original CYGNSS design. First, the antenna allows MuSat2 to gather measurements from satellites outside the U.S.-based GPS system, such as the European Space Agency’s Galileo satellites. This capability enables MuSat2 to collect more data as it orbits Earth, improving its assessments of conditions on the planet’s surface.
Second, whereas CYGNSS only collected cross-polar radar signals, the updated science antenna also collects co-polar radar signals. This additional information could provide improved information about soil moisture, sea ice, and vegetation. “There’s a whole lot of science value in looking at both polarization components scattering from the Earth’s surface. You can separate apart the effects of vegetation from the effects of surface, itself,” explained Ruf.
Hurricane Ida, as seen from the International Space Station. NASA-developed technology onboard MuSat2 will help supply the U.S. Air Force with critical data for producing reliable weather forecasts. NASA For Muon Space, this technology infusion has been helpful to the company’s business and science missions. Dallas Masters, Vice President of Muon’s Signals of Opportunity Program, explains that NASA’s investments in NGRx technology made it much easier to produce a viable commercial remote sensing satellite. According to Masters, “NGRx-derived technology allowed us to start planning a flight mission early in our company’s existence, based around a payload we knew had flight heritage.”
Dyer agrees. “The fact that ESTO proves out these measurement approaches – the technology and the instrument, the science that you can actually derive, the products from that instrument – is a huge enabler for companies like ours, because we can adopt it knowing that much of the physics risk has been retired,” he said.
Ultimately, this advanced antenna technology for measuring ocean surface wind speed will make it easier for researchers to turn raw data into actionable science products and to develop more accurate forecasts.
“Information is absolutely precious. When it comes to forecast models and trying to understand what’s about to happen, you have to have as good an idea as you can of what’s already happening in the real world,” said oceanographer Lew Gramer, an Associate Scientist with the Cooperative Institute For Marine And Atmospheric Studies and NOAA’s Hurricane Research Division.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Candeska Cikana Community College uses selective laser sintering, a type of 3D-printing in which heat and pressure form specific structures using layers of powdered material. Shown here, a student works to remove excess material, in this case a powdered form of nylon with carbon fibers, to reveal a prototype of the “Mapi Hapa,” or “sky shoe.” Candeska Cikana Community College Human exploration on the lunar surface is no small feat. It requires technologists and innovators from all walks of life to tackle many challenges, including feet.
From designing astronaut boots, addressing hazardous Moon dust, and researching new ways to land on Mars, NASA is funding valuable research through M-STAR (Minority University Research and Education Project’s (MUREP) Space Technology Artemis Research). The M-STAR program provides opportunities for students and faculty at Minority Serving Institutions to participate in space technology development through capacity building and research grants. With more than $11.5 million awarded since 2020, M-STAR aims to ensure NASA isn’t leaving any potential solution behind.
Best Foot Forward
Nicholas Bitner from Candeska Cikana Community College, left, and Jesse Rhoades from the University of North Dakota (UND), right, are pictured in UND’s BiPed lab, where their students test and capture motion data for the Mapi Hapa. Walter Criswell, UND Today Supportive boots are required for astronauts who will perform long duration Artemis missions on the Moon. With astronaut foot health in mind, students and faculty of North Dakota’s Candeska Cikana Community College in Fort Totten and the University of North Dakota in Grand Forks are designing a solution for extravehicular activity Moon boots. The project, called Mapi Hapa, proposes a 3D printed device that helps astronauts achieve the range of motion that takes place in the ankle when you draw your toe back towards the shin.
Candeska Cikana Community College is a tribal college that serves the Spirit Lake Nation, including the Dakota, Lakota, Sisseton, Wahpeton, and Yanktonai peoples.
Nicholas Bitner, an instructor at Candeska Cikana and graduate student at the University of North Dakota, notes the unique skills that tribal students possess. “Their perspective, which is unlike that of any other student body, thrives on building with their hands and taking time to make decisions.”
Bitner also attributes many opportunities and successes of their program to M-STAR and its partnership which exemplifies the dire importance of consistent funding.
“Given the relationships, we have been able to expand our capabilities and our lab, but it has also given us funding. We were able to hire all our students in the engineering department as lab technicians. So, they get paid to do the research that they are a part of, and not only do they have that psychological ownership, but they also have a good paying job that looks nice on their resumes.”
In addition to addressing astronaut foot health, M-STAR funding is helping develop solutions to combat lunar regolith, or Moon dust, which can damage landers, spacesuits, and human lungs, if inhaled.
Lunar Dust Development
With M-STAR, New Mexico State University in Las Cruces developed affordable, reliable lunar regolith simulants to help test lunar surface technologies. The team also designed testing facilities that mimic environmental conditions on the Moon.
New Mexico State has already started sharing their simulants, including with a fellow M-STAR awardee. An M-STAR project selected in 2023 from the University of Maryland Eastern Shore in Princess Anne uses the simulants to help test their experience in smart agriculture to test applications for crop production on the Moon.
University of Maryland, Eastern Shore explores the possibility of growing crops in lunar regolith by mixing varying proportions of lunar regolith simulant, horse manure, and potting soil. The lunar regolith simulant was provided by fellow M-STAR awardee at New Mexico State University in in Las Cruces.Stephanie Yeldell/NASA Douglas Cortez, associate professor in civil engineering at New Mexico State, believes different perspectives are essential to maximizing solutions.
“There are hundreds of people working at Minority Serving Institutions that are used to looking at the world in a completely different way,” said Cortez. “When they start looking at the same problem and parameters, they come up with very different solutions.”
As we look to sustainable presence on the Moon, NASA also has its sights set on Mars and M-STAR is helping develop technologies to inform crewed Martian exploration.
Stick the Landing
San Diego State University in California was awarded funding for research on Mars entry, descent, and landing technologies. The team aims to achieve optimal trajectory by developing onboard algorithms that guide vehicles to descent autonomously.
The M-STAR research opportunities have been invaluable to students like Chris Davami and his teammates working to develop improved methods to land on Mars.
Christopher Davami, who supported San Diego State University’s 2021 M-STAR project, is pictured here at NASA’s Langley Research Center, where he was selected for internships supporting research in aeroelasticity, atmospheric flight, and entry systems research.NASA “I would definitely not have been able to have these opportunities with NASA if it weren’t for M-STAR,” said Davami. “M-STAR helped pay for my education, which helped me save a lot in student loans. I probably wouldn’t be going to graduate school right now if I did not have this opportunity. This program enabled me to keep pursuing my research and continue doing what I love.”
Following his contributions to the M-STAR-funded project, Davami was awarded a NASA Space Technology Graduate Research Opportunity in 2023 on his work in autonomous end-to-end trajectory planning and guidance constrained entry and precision power decent.
Through efforts like M-STAR, NASA aims to seed the future workforce and prepare colleges and universities to win other NASA research opportunities. When it comes to the advancement of space technology, people of different backgrounds and skillsets are needed to achieve what was once known as impossible. Not only can the diversification of ideas spark fundamental innovations in space, but it can also help students apply these technological advancements to solving problems here on Earth.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Kathy Clark (left) and Ryan D. Brown have both served as chairs of NASA Glenn Research Center’s Disability Awareness Advisory Group, which works to help provide individuals with disabilities equal opportunities in all aspects of employment.Credit: NASA/Jef Janis Kathy Clark started her career at NASA’s Glenn Research Center in Cleveland straight out of high school, and when offered either a job as an accountant or a job in training, the choice was crystal clear.
“I started in training, I’ve stayed in training, and I’ll probably retire in training,” said Clark, now a human resources specialist and program manager of NASA Glenn’s mentoring program, Shaping Professionals and Relating Knowledge (SPARK). “I just love people.”
Celebrating 41 years at NASA this October, Clark has long been an advocate for employees. For over 12 years, she served as chair of the center’s Disability Awareness Advisory Group (DAAG), which works to help provide individuals with disabilities equal opportunities in all aspects of employment. The group also strives to identify and eliminate workplace barriers, raise awareness, and ensure accessible facilities.
After recently stepping down, Clark reflects on her legacy of creating change with the group and looks to the next generation of leadership, including longtime member and new chair Ryan D. Brown, to continue its important mission.
“Don’t Let a Disability Stop You”
Clark joined DAAG around 12 years into her career, after she was diagnosed with multiple sclerosis. She was later asked to serve as chair after she helped bring a traveling mural to the center that showcased Ohio artists with disabilities.
During Clark’s time as chair, the group helped secure reserved parking spaces for employees with disabilities, instead of just relying on a first-come first-serve system for accessible spots. She recalls DAAG championing other facility issues, such as fixing a broken elevator and faulty door that presented challenges for folks with disabilities. The group has also worked with human resources to compile best practices for interviews, hosted various speakers, and offered a space for members to share about their disabilities.
“I was honored to be the chair and just be there for the people and to try to make a difference, to let them know, if you need something, reach out,” Clark said. “Don’t let a disability stop you.”
“I was honored to be the chair and just be there for the people and to try to make a difference, to let them know, if you need something, reach out."

“Let’s Go Above and Beyond”
When it was time to choose Clark’s successor, she said, another supportive and vocal member stood out: Brown.
Thanks to an Ohio program for individuals with disabilities, Brown was placed at NASA as an intern in 2006, later completing a co-op that led to a full-time accounting position at the center, where he now works as a lead in the financial systems branch.
More than one in four adults in the United States have some type of disability, according to the U.S. Centers for Disease Control and Prevention, and some are not always easy to see, Brown says. For instance, Brown has an invisible disability: a learning disability related to reading and writing. After connecting with a coworker early in his career who was a member of DAAG, Brown reached out to Clark to join.
“Everyone has their challenges, regardless of if you have a disability or not, so making people comfortable talking about it and bringing it up is always good,” he said. “I think I’ve always liked speaking up for individuals and trying to spread that awareness, which has been great with DAAG.”
Now the chair, Brown has supported the group in developing a job aid to help employees understand how to self-identify as having a disability. They’ve also recently organized awareness events to help other employees understand the experiences and challenges of individuals with disabilities.
DAAG also continues to champion facility updates. For example, the group is currently working to get automatic door openers installed for bathrooms in buildings at the center where many employees gather.
“Let’s try to go above and beyond and really make it easier on individuals,” Brown said.

“Make a Difference”
Membership in the group is growing, and Clark looks forward to its future.
“I could not have turned over the chair role to a better person than Ryan,” she said.
Brown’s vision is to continue spreading the word that the group is available as a resource for employees, and for others throughout the center to be more aware of the experiences of individuals with disabilities. The work he does to help others inspires him every day, he says.
“We’re here for individuals that don’t want to speak up, we’re here for individuals if they run into issues – they can always contact us,” Brown said. “It’s all about getting up there and trying to make a difference.”
