Mitchell High grad Noah Larson, SDSU team impress NASA with moon rover prototype
Noah Larson, a 2024 graduate of Mitchell High School and a freshman at South Dakota State University, was part of a team of fellow students from Brookings who secured the Best Prototype Award at the Revolutionary Aerospace Systems — Academic Linkage (RASC-AL), an annual contest sponsored by NASA and administered by the National Institute of Aerospace for undergraduate and graduate students.
The competition took place in Cocoa Beach, Florida, in June.
"It's a competition that NASA puts on yearly. Basically, they will give a theme for the year, or multiple themes," Larson told the Mitchell Republic in a recent interview. "And then schools across the country are welcome to submit proposals for how they'd solve that issue."
The theme Larson's team chose was a small lunar rover. Dubbed NOVA for Next-gen Operations Virtual Assistant, the team had to come up with a design for a rover that would be able to do minor repairs, maintenance, and make connections to help set up lunar infrastructure for a lunar base that would be put on the moon by 2038.
NASA earlier this year had announced 14 finalist teams in multiple categories. Among those teams were engineering university mainstays like Virginia Tech and the Massachusetts Institute of Technology. NOVA was among two teams from SDSU at the competition, where teams had 25 minutes to explain their projects to judges and then took another 20 minutes of questions.
The NOVA team, made up of seven freshmen and two juniors, set out on creating their rover late last year.
"It had to be under 500 kilograms and be able to lift certain capacities for payloads on the moon," said Larson, who is studying mechanical engineering with a specialization in aerospace engineering. "There is a lot of cutting as much weight as possible while making sure it will still hold under weight."
They submitted their proposal and began working on their prototype design right away. The rover prototype is one-sixth scale and equipped to perform a selected number of tasks chosen by the team, so the team chose tasks that could be readily shown off during the competition. All told the rover measured about two-feet by two-feet by two-feet.
Larson said the team had focused on making functional the forklift system on the back, which was designed to handle heavier payloads, and the arm on the front to manipulate smaller objects with precision.
One challenge that came with the project was implementing designs to help the rover survive working in moon regolith, essentially moon dust that gets anywhere and everywhere and can cause damage to manmade equipment.
"It's basically just moon dust, but there is no atmosphere on the moon, so it doesn't degrade. So lunar regolith is basically just little saw blades," Larson said. "So anything on the moon has to be able to take care of dust before it shreds itself apart. The judges really hammered home on how you are going to protect your systems from being destroyed on the moon."
Arguably the ace in the hole for the NOVA team was the fact that their prototype actually functioned, at least on a limited scale. While other teams presented models that would represent their designs, the team from SDSU brought an actual, functioning prototype for review.
The novelty of seeing the rover moving around and showing off its functions appeared to be enough for the judges to give the award to the NOVA team.
"It felt really good to be getting an award like that, especially because a lot of people show up with kind of a model of how their prototype is supposed to look. Some people do show up with a semi-working prototype. So it feels good to actually have something that we designed that can function and we can see work," Larson said.
Traditionally, not every team even brings a prototype to the competition, but this year 13 of the 14 finalists did. Having the lone functioning prototype helped the NOVA team stand out, Larson said.
With the competition over and the team now returned home, the prototype rover is set to be used as part of a master's thesis project of another SDSU mechanical engineering student. Larson, in the meantime, has returned to Mitchell to take a break from academics and to work at his summer job.
Larson has aspirations of working in the aerospace industry, perhaps with military jets or in the realm of space. He has also considered working with Aerofly, a Brooking startup founded by SDSU graduate advisers. A summer job there would be a great way to get experience in the industry, he said.
But for now he'll concentrate on his studies and next year's event. There was some concern that recent funding issues would mean the end of the RASC-AL competition, but Larson said he learned recently that the contest is indeed on again for next year. It won't be long before the organizers release the theme for next year's contest.
When they do, Larson and his fellow budding engineers will be ready.
"The theme should be released in about a month," Larson said. "So once we get that, we'll get to work again."

NASA intern stole $21M of Lunar to use during sex to have ‘sex on the moon'
He promised her the Moon — and meant it. More than 23 years ago, NASA intern Thad Roberts hatched a daring plan to steal 17 pounds of moon rocks and a meteorite from Houston's Johnson Space Center — priceless samples from every Apollo mission, locked in a 600-pound safe and valued at $21 million, according to the FBI. Only 24 years old with a triple major in physics, geology, and geophysics at the University of Utah, with a wife he was supporting back in Utah, and financially struggling, Roberts thought his plan was foolproof. The first step was finding a buyer. With help from friend Gordon McWhorter, Roberts connected online with a potential Belgian purchaser willing to pay $1,000 to $5,000 per gram. The buyer, however, grew suspicious and alerted the FBI, who instructed him to keep talking while they investigated. Around this time, he met Tiffany Fowler, a 22-year-old NASA intern conducting stem cell research. Their friendship quickly became romantic, and after three weeks, they moved in together. When Roberts revealed his plan, Fowler agreed to help. They recruited another NASA intern, Shae Saur, and one night the trio used their NASA IDs to slip into the Johnson Space Center, making off with the entire safe. Back at the hotel, they cracked it open with a power saw. On July 20, 2002—the 33rd anniversary of the first moon landing—Roberts and Fowler drove to Orlando to meet family members of the Belgian buyer. While waiting, Roberts placed moon rocks beneath the bed covers, later claiming the couple had 'sex on the moon' as a symbolic gesture. 'I take some of the moon rocks and I put them underneath the blanket on the bed… I never said anything but I'm sure she could feel it,' he told CBS News in 2012. 'It was more about the symbol of what we were doing, basically having sex on the moon. It's more uncomfortable than not, but it wasn't about the comfort at that point. It was about the expression. And no one had ever had sex on the moon before. I think we can safely say that.' When they met with the supposed buyers, they were instead greeted by undercover FBI agents. The moon rocks were recovered from their hotel room, though the FBI reported they were now 'virtually useless to the scientific community' and that the heist destroyed three decades of handwritten research notes by a NASA scientist. After his arrest, Roberts admitted to also stealing dinosaur bones and fossils from the Natural History Museum in Salt Lake City. When asked why he stole the moon rocks, Robert told CBS News he 'wasn't' looking at it like stealing at the time. 'We weren't going to take this money we were getting from it to go buy a yacht or lots of cars or a big house. We were gonna live just the small kind of lifestyle we were, but fund science that might change the world, you know?' he said. In the end, Roberts, Fowler, and Saur all pleaded guilty to conspiracy to commit theft and interstate transportation of stolen property. Roberts was sentenced to eight years in federal prison, serving six. Fowler and Saur each received 180 days of house arrest and 150 hours of community service. McWhorter, convicted at trial, was given six years in prison. Roberts and Fowler never saw each other again. Solve the daily Crossword

NASA launches second phase of moon recycling competition
Aug. 11 (UPI) -- NASA is launching the second phase of its moon recycling competition to clean up trash in space. The space agency's LunaRecycle Challenge is looking for the brightest minds to figure out a way to recycle plastics, foams and metals left behind by ongoing activity and building in space. "NASA is eager to see how reimagining these materials can be helpful to potential future planetary surface missions," said Jennifer Edmunson, acting program manager for Centennial Challenges at NASA's Marshall Space Flight Center in Alabama. "I'm confident focusing on the most critical trash items -- and integration of the prototype and digital twin competition tracks -- will yield remarkable solutions," Edmunson added, "that could enable a sustainable human presence off-Earth and transform the future of space exploration." As the United States discusses replacing the International Space Station and placing a small nuclear reactor on the moon, the potential for increased waste in space is growing. LunaRecycle's Phase 1 competition attracted record-breaking interest with more than 1,200 registrations. Seventeen teams, from five countries and nine U.S. states, were named winners in that challenge. For Phase 2, only U.S. individuals and teams may participate and must build a physical prototype to manage a year's worth of trash. The challenge estimates a crew of four astronauts would produce more than 4,600 pounds of single-use waste to include food packaging and discarded clothing. The goal for competitors is to recycle the waste, while minimizing crew time and any hazards. Submissions for NASA's LunaRecycle milestone round, which is being administered by the University of Alabama, are open now and due January 2026. Finalists from that round will be announced in February with up to 20 finalists competing in the challenge's in-person prototype demonstrations next August. Successful solutions in both rounds could net winners cash prizes totaling $2 million. Solve the daily Crossword

NASA is putting a nuclear reactor on the moon. It could reshape space governance
The first space race was about flags and footprints. Now, decades later, landing on the moon is old news. The new race is to build there, and doing so hinges on power. In April 2025, China reportedly unveiled plans to build a nuclear power plant on the moon by 2035. This plant would support its planned international lunar research station. The United States countered in August, when acting NASA Administrator Sean Duffy reportedly suggested a U.S. reactor would be operational on the moon by 2030. While it might feel like a sudden sprint, this isn't exactly breaking news. NASA and the Department of Energy have spent years quietly developing small nuclear power systems to power lunar bases, mining operations, and long-term habitats. As a space lawyer focused on long-term human advancement into space, I see this not as an arms race but as a strategic infrastructure race. And in this case, infrastructure is influence. A lunar nuclear reactor may sound dramatic, but it's neither illegal nor unprecedented. If deployed responsibly, it could allow countries to peacefully explore the moon, fuel their economic growth, and test out technologies for deeper space missions. But building a reactor also raises critical questions about access and power. The legal framework already exists Nuclear power in space radioisotope generators that use small amounts of radioactive elements—a type of nuclear fuel— to power satellites, Mars rovers, and the Voyager probes. The United Nations' 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space, a nonbinding resolution, recognizes that nuclear energy may be essential for missions where solar power is insufficient. This resolution sets guidelines for safety, transparency, and international consultation. Nothing in international law prohibits the peaceful use of nuclear power on the moon. But what matters is how countries deploy it. And the first country to succeed could shape the norms for expectations, behaviors, and legal interpretations related to lunar presence and influence. Why being first matters The 1967 Outer Space Treaty, ratified by all major spacefaring nations including the U.S., China, and Russia, governs space activity. Its Article IX requires that states act with 'due regard to the corresponding interests of all other States Parties.' That statement means if one country places a nuclear reactor on the moon, others must navigate around it, legally and physically. In effect, it draws a line on the lunar map. If the reactor anchors a larger, long-term facility, it could quietly shape what countries do and how their moves are interpreted legally, on the moon and beyond. Other articles in the Outer Space Treaty set similar boundaries on behavior, even as they encourage cooperation. They affirm that all countries have the right to freely explore and access the moon and other celestial bodies, but they explicitly prohibit territorial claims or assertions of sovereignty. At the same time, the treaty acknowledges that countries may establish installations such as bases—and with that, gain the power to limit access. While visits by other countries are encouraged as a transparency measure, they must be preceded by prior consultations. Effectively, this grants operators a degree of control over who can enter and when. Building infrastructure is not staking a territorial claim. No one can own the moon, but one country setting up a reactor could shape where and how others operate—functionally, if not legally. Infrastructure is influence where ice found in perpetually shadowed craters could fuel rockets and sustain lunar bases. These sought-after regions are scientifically vital and geopolitically sensitive, as multiple countries want to build bases or conduct research there. Building infrastructure in these areas would cement a country's ability to access the resources there and potentially exclude others from doing the same. Critics may worry about radiation risks. Even if designed for peaceful use and contained properly, reactors introduce new environmental and operational hazards, particularly in a dangerous setting such as space. But the U.N. guidelines do outline rigorous safety protocols, and following them could potentially mitigate these concerns. Why nuclear? Because solar has limits The moon has little atmosphere and experiences 14-day stretches of darkness. In some shadowed craters, where ice is likely to be found, sunlight never reaches the surface at all. These issues make solar energy unreliable, if not impossible, in some of the most critical regions. A small lunar reactor could operate continuously for a decade or more, powering habitats, rovers, 3D printers, and life-support systems. Nuclear power could be the linchpin for long-term human activity. And it's not just about the Moon—developing this capability is essential for missions to Mars, where solar power is even more constrained. A call for governance, not alarm The United States has an opportunity to lead not just in technology but in governance. If it commits to sharing its plans publicly, following Article IX of the Outer Space Treaty and reaffirming a commitment to peaceful use and international participation, it will encourage other countries to do the same. The future of the moon won't be determined by who plants the most flags. It will be determined by who builds what, and how. Nuclear power may be essential for that future. Building transparently and in line with international guidelines would allow countries to more safely realize that future. A reactor on the moon isn't a territorial claim or a declaration of war. But it is infrastructure. And infrastructure will be how countries display power—of all kinds—in the next era of space exploration. Michelle L.D.
