Imagine a world where sudden solar flares could knock out our power grids, cripple communication networks, and render GPS useless. Scary, right? But a team of bright undergraduate students is taking a bold step to protect us from this very threat, and they're doing it with a satellite they built themselves!
These aren't your typical classroom projects; this is a fully functional mini-satellite, known as a CubeSat, designed and constructed by a multidisciplinary team spanning three universities. Their mission? To venture into space and collect invaluable data in collaboration with NASA's Interstellar Mapping and Acceleration Probe (IMAP) mission. This collaboration is important because it allows for cross-validation of data, leading to more robust and reliable findings.
Mark your calendars! The launch is scheduled for no earlier than November 10, 2025, at 10:19 a.m. PST from Vandenberg Space Force Base in California. Strapped to a SpaceX rocket, this tiny powerhouse will journey to the outer reaches of our atmosphere to study the solar wind. For those unfamiliar, the solar wind is a stream of charged particles constantly emanating from the sun. Understanding its behavior is critical because it directly influences space weather.
The ultimate goal? To improve our ability to forecast space weather and safeguard the technologies we rely on every day – from communication networks and power grids to GPS systems. Large solar flares can unleash tremendous amounts of energy, potentially causing widespread damage and disruption. And this is the part most people miss: the economic impact of a major space weather event could be staggering, costing billions of dollars in repairs and lost productivity.
"This is an amazing opportunity for students to not only get hands-on technical experience but to also collaborate with other undergraduates across the country to design and build an entire space mission from the instrument to the software that will operate it in space and the antenna and radio to command the satellite once in space," explains Noé Lugaz, research professor in physics and astronomy at the University of New Hampshire. He emphasizes that "the experience is invaluable and can open doors to future opportunities in space-related or other science and engineering careers."
But here's where it gets controversial... some argue that CubeSats, while cost-effective for research and education, aren't robust enough to provide long-term, reliable space weather data compared to larger, more sophisticated satellites. What do you think? Is the trade-off between cost and capability worth it?
The team, comprised of 70 undergraduate students from the University of New Hampshire (UNH), Sonoma State University (SSU), and Howard University (HU), poured their hearts and minds into designing, developing, and building the satellite. They christened it 3UCubed, a name that reflects their mission of uplifting undergraduate students to study upwelling and a clever nod to the three participating universities. The name also highlights the collaborative spirit of the project, showcasing how students from diverse backgrounds can come together to achieve a common goal.
Selected as part of NASA's CubeSat Launch Initiative, the 3UCubed satellite will venture into the Earth's upper atmosphere, also known as the thermosphere. This is the same region where many other satellites and even the International Space Station orbit our planet. The satellite will meticulously measure atmospheric density (specifically, single oxygen atoms at that altitude) and electron precipitation from space onto the upper atmosphere. These measurements are vital for understanding how the thermosphere behaves under different conditions.
The data collected by the students will be meticulously analyzed in conjunction with data from IMAP. This combined analysis will help scientists gain a deeper understanding of how the thermosphere in the auroral and cusp regions (areas near the Earth's poles) responds to particle precipitation and the ever-changing conditions associated with the solar wind. This understanding is crucial for developing more accurate models of the thermosphere, which can then be used to improve space weather forecasting.
CubeSats represent a specific category of satellites: small, standardized, and cost-effective. Roughly the size of a loaf of bread, they offer a simpler and more accessible path to building and operating a satellite compared to their larger counterparts. This makes them an ideal platform for students to hone their skills and gain hands-on experience outside the traditional classroom setting. Think of it as a gateway to space exploration, empowering the next generation of scientists and engineers.
For five years, these dedicated students immersed themselves in every aspect of the project, from writing the software code that controls 3UCubed to meticulously soldering wires during the physical construction. Guided by professors and staff engineers, they conducted trade studies, analyzed orbits, selected vendors for various subsystems, managed budgets for mass, power, link, and telemetry, and developed the framework for the flight software and operations. The sheer scope of responsibilities provided invaluable real-world experience.
"At the time, I had a keen interest for the aerospace industry and saw this as a great opportunity to get valuable experience working with industry professionals," recalls Alex Chesley '22, a mechanical engineering graduate from UNH and a member of the 3UCubed team. "It was fascinating to learn about so many new subjects about space science and instrumentation that I had never studied before." His experience perfectly exemplifies how this project can ignite a passion for space science and engineering.
This hands-on experience is specifically designed to introduce, inspire, and prepare students for successful careers in fields like space science, computer science, engineering, and science education. Chesley, for example, designed the initial CAD model of the satellite and helped create the detailed specification list for the CubeSat's altitude control system. He now works as a configuration engineer at STS Aerospace, applying the skills he gained on the 3UCubed project to develop fluid distribution systems for the space, aeronautics, and defense industries. His story is a testament to the power of hands-on learning.
The 3UCubed satellite was fully assembled at UNH, and the two payload instruments within its structure were built, tested, and calibrated there as well. UNH students spearheaded the development of the instrument software, collaborating with SSU students on the flight software. This collaborative approach fosters a sense of teamwork and shared responsibility, crucial skills for success in any STEM field.
SSU took the lead in developing the software for the ground station, which will serve as the primary hub for the mission. The ground station will collect data from the satellite and send commands to the spacecraft, allowing it to adjust its orbit and operations once in space. UNH collaborated with HU to build the backup ground station, ensuring redundancy and reliability for the mission. This distributed architecture highlights the importance of collaboration and communication in complex engineering projects.
"The SSU CubeSat Project had a profound impact on my personal and professional growth," says Haley Joerger '24, a computer science graduate from SSU. "The mentorship I received was instrumental in building my confidence and guiding my development. Working on the CubeSat hardware provided me with valuable experience in instrumentation, a skill that I now apply in my role as an application engineer at Keysight Technologies. I am also deeply grateful for the lifelong friendships I formed with my teammates—connections that continue to enrich my life to this day." Her words underscore the transformative power of this project, not only in terms of technical skills but also in terms of personal growth and community building.
Students from Sonoma State University have also engaged with their region's amateur radio operators and Scout members to construct a ground station for them to communicate with the satellite. This outreach component demonstrates the project's commitment to education and community engagement, inspiring the next generation of space enthusiasts.
