CU ��ý�� faculty and students have been part of than 24 small satellite projects. Find out more about all of our missions.

Three ��ý�� small satellites are ready to rocket into space.

Designed, built, and tested on campus, all three projects are led by Robert Marshall, an associate professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences.

“We’ve designed and built each of these missions completely from scratch. I’m very proud of the entire team. I don’t know how to describe it, going from the idea of a mission, to a proposal, then construction, resolving problems along the way, and now getting to launch,” Marshall said.

The satellites, AEPEX, CANVAS, and COSMO, will serve separate missions, but each are CubeSats, so-named for their small size. CANVAS is roughly the size and shape of a loaf of bread. The two other satellites are the size of a large shoebox.

Satellite building used to exclusively be the domain of major aerospace companies, often costing hundreds of millions of dollars each and weighing in at thousands of pounds. Advancing technology has made CubeSats’ much smaller profiles practical.

They have more limited missions, but also radically reduce costs; COSMO is the most expensive of the three, at $6.4 million. Additionally, as university projects, they offer the chance for students to be heavily involved.

“Students bring a lot of excitement,” Marshall said. “We’ve had over 60 students involved in developing these missions, including undergrads, masters, and PhDs.”

Jacob Mesley, a 2nd year aerospace master’s student, has been part of that COSMO team.

“I’m just so grateful for this opportunity, sometimes I can still hardly believe it. If you told me three years ago that I would end up working on hardware that’s going to be orbiting Earth so soon, I would have likely not believed you,” Mesley said.

All of the CubeSats will launch from Vandenberg Space Force Base in California. AEPEX and COSMO are slated for the same SpaceX rocket, likely to take off in late March. CANVAS will follow a few weeks later, aboard a Northrop Grumman rocket.

Once in space, the next phase for the satellites begins.

“The real mission research doesn’t happen until after the launch. We develop the satellites, but the ultimate goal is the science you can do with them in orbit,” Marshall said.

Each satellite has a very different science mission:

AEPEX (Atmospheric Effects of Precipitation through Energetic X-rays) – Will investigate highly energetic electrons that fall into Earth’s atmosphere from the Van Allen radiation belts by measuring X-rays that are produced in the atmosphere. These electrons impact atmospheric ozone balance and satellite communications.
CANVAS (Climatology of Anthropogenic and Natural VLF wave Activity in Space) – Will map the transmission into space of Very Low Frequency energy generated by lightning strikes and ground-based radio transmitters, which have a significant impact on the near-Earth radiation environment.
COSMO (COmpact Spaceborne Magnetic Observatory) – Will conduct high accuracy measurements of Earth’s magnetic field, providing essential information for navigation.

“It’s very exciting to get to this point. The science missions last from six months to three years, and we hope to extend some of them if we’re able to get funding. More data is always better to improve our understanding,” Marshall said.

Additional key leadership on all three satellites came from Conor Cunningham, Siwani Regmi, and Sebastian Wankmueller, all professional research associates in Marshall’s lab, as well as the SmallSat team at the Laboratory for Atmospheric and Space Physics (LASP), who have led aspects of the spacecraft design and will operate each of the spacecraft once in orbit.

CU ��ý�� team earns second in Capture the Satellite Challenge

CU ��ý�� team earns second in Capture the Satellite Challenge Jeff Zehnder Tue, 02/17/2026 - 09:22

Afrah Ghedira, Lorenzzo Mantovani and Mark Stephenson

A team of three aerospace PhD students were awarded second place in an autonomous satellite systems competition.

Afrah Ghedira, Lorenzzo Mantovani and Mark Stephenson competed in the 2026 Capture the Satellite Challenge organized by the American Institute of Aeronautics and Astronautics.

The goal? To design an automated approach for a simulated maneuvering satellite during non-cooperative space operations. It is a well-known game theory application for orbital dynamics called a “lady, bandit, guard problem.”

“Your satellite is the bandit. You’re trying to get as close as possible to the lady satellite, but the guard satellite is trying to keep you away,” Stephenson said.

Critically, the satellites had to act completely on their own. Once programmed and unleashed, no human intervention was allowed.

All three students are studying under Hanspeter Schaub, distinguished professor and chair of the Ann and H.J. Smead Department of Aerospace Engineering Sciences. Schaub’s lab focuses on complex orbital mechanics and created Basilisk, an open-source program for space guidance, estimation and control solutions.

Reinforcement Learning

Using the software, the team developed algorithms, based on the rules of the game, to model both their satellite and potential guard behaviors.

“We had to train our agent against a wide range of possible guards,” Mantovani said. “It’s the hardest part of any game. You need to have good behavior for yourself and also the other side. It’d be easy to play chess with someone if you knew what their move would be.”

Through the reinforcement learning aspect, they ran thousands of simulations for the agent to improve performance.

Unexpected Results

During those repeat simulations, their agent developed an unexpected approach. The premise of the game was to rendezvous for an extended period with the lady satellite, as though for maintenance, but the formal rules were more general, requiring only a momentary approach.

“Our agent learned kind of a funny strategy,” Ghedira said. “If you’re near the lady for too long, it gives lots of opportunity for the guard to come close. So, our agent would fake out the guard, fly far away and then apply full thrust to zoom close by the lady really fast and keep flying away.”

Through the reinforcement learning, their model realized something the team members had not.

“Initially we thought something was wrong, but based on the scoring, getting close to the guard was more penalized than getting close to the lady was rewarded, so it was a pretty reasonable strategy,” Ghedira said.

Fifty-two teams registered for the AIAA competition, which used the Kerbal Space Program, a computer game highly regarded for accuracy in simulating challenging orbital dynamics situations.

“This is a realistic environment. With any sort of autonomy and reinforcement learning project, the big question is can it work in an environment you don’t control. In our lab, we had a lot of the tooling to approach this problem in a really interesting way,” Mantovani said.

Future View

The use of autonomy in orbiting satellites is still in its infancy, and Stephenson said the competition was a good opportunity to experiment in a new domain.

“I’ve been looking at industry research proposals that are adjacent to this kind of problem and am glad to get experience on this type of thing. The industry is just opening its eyes to autonomy and what we can do if we enable these technologies for space like is being done on Earth in robotics and self-driving cars,” Stephenson said.

The competition was held during the 2026 AIAA SciTech Conference in Orlando, Florida, on Jan. 12-16.

Naval grant to improve ionospheric research over the open ocean

Naval grant to improve ionospheric research over the open ocean Jeff Zehnder Mon, 10/27/2025 - 16:27

Jeff Zehnder

Brian Breitsch is improving our understanding of the upper atmosphere in some of the most isolated places on Earth.

A research associate in the Ann and H.J. Smead Department of Aerospace Engineering Sciences, Breitsch is leading an $840,000 U.S. Office of Naval Research project to study the ionosphere, which spans from roughly 50-1000 km (31-621 mi) in altitude above the Earth.

It is an area where solar flares and other space weather can wreak havoc with high frequency communications and radar signals.

“This region of the atmosphere is ionized due to the sun’s radiation. There are all these free electrons and ions floating around, otherwise known as plasma, and the structure of this plasma impacts radio signals that travel through it. We want to be able to better see what’s going on in this region,” Breitsch said.

Day-to-day ionosphere forecasting works fairly well over populated continents, thanks to a broad network of ground sensors. However, there is much less data covering areas over the ocean. Although few people live on the water, such regions are crucial to Naval communications and operations. It is this region, specifically at equatorial latitudes, where Breitsch’s work will focus.

“We don’t have many sensors at the surface here, since they’d have to be deployed on boats or buoys. Instead, we want to use satellite-based reflectometry, which roughly mimics the type of measurement geometry we’d get from ground receivers,” he said.

Breitsch is an alumnus of CU ��ý��, earning his aerospace engineering sciences PhD in Professor Jade Morton’s lab in 2021. A leader in the remote sensing field, Morton is also involved in Breitsch’s grant.

The research process involves GPS satellites and other similar global navigation satellite systems (GNSS). The signals from these satellites continuously blanket the planet. When beamed down, some of that signal reflects off the surface and bounces back into space, where it can be picked up by other satellites in low Earth orbit.

When those signals travel through the ionosphere, they undergo subtle changes that can be used to measure the plasma structure.

“We’re at the forefront of processing those signals and using them to estimate the ionosphere. Reflectometry gives us geometries of measurement over the ocean that we wouldn’t otherwise have,” Breitsch said.

That data is already being collected and is available to researchers, but it is extremely difficult to analyze.

“We only get coherent reflections when the sea is calm. One of the main things we’re trying to do in this project is work with noncoherent reflections from rough seas. To do that, we need to analyze data over longer timespans. It’s much more challenging,” he said.

Over the next three years, Breitsch will work with graduate students to develop signal processing techniques to extract useful information from the data. They will also validate and integrate this data with other measurements from other sources, including radio occultation receivers, ground-based radars, and Android phone GPS receivers.

“This is a tough estimation problem, but the ionosphere and the science of it all is really cool. These techniques we’re working on might be the future of GNSS reflectometry for ionosphere observation,” Breitsch said.

In addition to Breitsch, researchers on the grant include PhD student Jiawei Xu and two co-investigators, Morton and Smead Aerospace Distinguished Professor Penina Axelrad.

New endowed professorship in space policy and law to expand frontiers of global collaboration

Jeff Zehnder — Tue, 24 Jun 2025 20:31:51 +0000

New endowed professorship in space policy and law to expand frontiers of global collaboration Jeff Zehnder Tue, 06/24/2025 - 14:31

$2.5 million investment will support teaching, research in cutting-edge field.

Through a generous investment in the future of space governance, CU ��ý�� donors Dale and Patricia Hatfield have given $2.5 million to establish the Hatfield Endowed Professorship in Space Policy & Law.

Underscoring the university’s commitment to leadership in this fast-evolving field, the professorship will drive teaching and research on space policy and law, with broad implications for national security, global communications, navigation, weather forecasting and international collaboration.

This interdisciplinary position will rotate every two years between the College of Engineering and Applied Science, the Leeds Schools of Business and Silicon Flatirons, supporting faculty whose teaching and research advance this work. Professor Marcus J. Holzinger of aerospace engineering sciences is the inaugural Hatfield Endowed Professor, bringing expertise in space policy, domain awareness, development and strategy.

“As humanity ventures beyond our planet, space law and policy have emerged as a new frontier, offering vast opportunities to shape the future of space exploration and utilization,” Dale Hatfield said. “The realm of space beckons a new generation to establish the legal and policy frame that will govern our cosmic endeavors.”

Building on strengths for greater impact

The Ann & H.J. Smead Department of Aerospace Engineering Sciences building

With this position, CU ��ý�� will help address the legal and policy challenges of space activities — advancing critical knowledge and preparing the next generation of leaders in outer space governance.

The university already boasts strengths in aerospace engineering, public policy and international law, with powerful research and industry partnerships across these areas. The addition of a dedicated, endowed professorship — along with the new Colorado Space Policy Center — will unify and elevate these efforts, helping to attract and retain top researchers, as well as distinguish the campus as a leader in outer space governance.

As the first appointment to the Hatfield Endowed Professorship, Holzinger will use his policy research — combining astrodynamics and geopolitics — to build a future in space that’s based on democratic norms.

“The Third Space Age presents a choice: Will we build a future in space guided by proven values and foresight, or will we extend old conflicts into this new arena?” said Holzinger. “Space is already deeply integrated into our global society, but traditional approaches to preventing conflict don’t meet our emerging needs in this complex environment. My research confronts these emerging challenges directly.

“By combining the physics of space with the dynamics of international strategy, we are charting new frameworks. The objective is to craft fresh views on deterrence and cooperation, establishing norms for responsible conduct that will safeguard our expanding human enterprise, on Earth and beyond.”

In addition to direct funding for the holder of the professorship, the endowment will fund research, course development, conference attendance and related efforts that strengthen the university’s work in space policy and law.

This flexible funding model will give Holzinger and future holders the tools they need to explore big ideas and offer students valuable learning opportunities.

“The Hatfield Endowed Professorship will directly facilitate my research,” Holzinger said. “It will enable and encourage engagement in national and international policy debates and facilitate network-building with key decision-makers essential for shaping sound space strategy.”

Furthermore, the rotating structure of the position is specifically designed to encourage collaboration across engineering, law and business — mirroring the real-world intersections shaping today’s space landscape.

The power of philanthropy

Dale and Pat Hatfield

Dale Hatfield, a pioneer in telecommunications policy, is known for his leadership in both government and academia. He began his career as chief of the Office of Plans and Policy at the Federal Communications Commission (FCC) in Washington, D.C., before moving to the National Telecommunications and Information Administration. He then founded a ��ý��-based consulting firm before rejoining the FCC as chief technologist, eventually serving as chief of the Office of Engineering and Technology. He now serves as a distinguished advisor at Silicon Flatirons and an adjunct professor at CU ��ý��.

Dale and his wife, Patricia, have supported the university for years, including an endowed professorship and scholarship fund for the ATLAS Institute, scholarships for the Lattice Scholars program and support for Colorado Law. Their latest investment exemplifies how private philanthropy can catalyze new areas of research, teaching and discovery.

By establishing this endowed professorship, the Hatfields are making a commitment to a future defined by innovation, cooperation and responsible exploration — where a new generation of space leaders can make their mark.

Dale summed it up by saying, “As Horace Greeley once urged pioneers to ‘go West,’ today we encourage young visionaries to go into space policy and law, to explore and to find the legal and policy landscapes of our new frontier beyond Earth.”

Silicon Flatirons to Host Inaugural Space and Spectrum Policy Conference

Silicon Flatirons to Host Inaugural Space and Spectrum Policy Conference Jeff Zehnder Tue, 06/17/2025 - 14:48

In theory, space is infinite. In practice, it is not.

Practical and physical limitations of the space environment are now evident as stakeholders wish to use resources in space. As barriers to entry in space continue to fall, and resource conflicts emerge, this begs the question: what is the correct way to regulate space?

On June 24 and 25, Silicon Flatirons will aim to examine this urgent question at the inaugural Space and Spectrum Policy Conference hosted at Colorado Law. The event, titled “Challenges in Sustaining Space as a Resource,” will highlight the challenges of space sustainment, and explore technical, regulatory, and cultural issues that must be addressed.

“The increasing exploitation of space is obvious to even the casual observer,” said Keith Gremban, Senior Fellow at Silicon Flatirons and Research Professor at the ��ý��’s Colorado Center for Astrodynamics Research (CCAR). “Any area that is growing so quickly is bound to stretch the borders of existing technology, regulations, and policy. Space also has the property of being international, which opens up an additional range of regulatory and policy concerns.”

"This conference examines urgent issues as commercial space activity quickly outruns existing space regulations,” said Brad Bernthal, Executive Director of Silicon Flatirons. “This is what Silicon Flatirons does best. We convene top experts, and different opinions, to tackle tough questions in technology policy.”

Conference topics will range from addressing the challenges of maintaining orbital space as a resource to issues like managing radio frequencies to keep satellite communications from interfering with each other or with terrestrial communications. Sessions include “Historical Lessons for Governing the Final Frontier,” “Contemporary Challenges in Space Governance,” and “Resolving Spectrum Conflicts Between Active Users in Space and on Earth.”

“Exploitation of space can be a huge benefit for the U.S. and the entire world if managed appropriately,” Gremban explained. “However, as with any other natural resource, inappropriate actions can have drastic consequences for everyone. It’s time to draw attention to the challenges of regulating space in order to maintain it as a global resource. As we know, regulation can stifle or encourage innovation.”

Colorado Law serves as a superb launch point for the conference. The state itself is a hub for the space industry and is already home to a number of existing and startup space companies such as Lockheed Martin and Raytheon, as well as newcomers Kayhan Space and Capella Space. Additionally, CU houses one of the largest aerospace engineering departments in the U.S. along with the Laboratory for Atmospheric and Space Physics (LASP), one of the premier academic institutes exploring space.

Keynote speakers include Anna Gomez, FCC Commissioner; David Goldman, Vice President of Satellite Policy at SpaceX; and Adam Cassady, Principal Deputy Assistant Secretary and Deputy Administrator at the National Telecommunications and Information Administration (NTIA). In addition to the three keynote addresses, participants will hear from more than 25 different speakers across seven sessions. The results of the conference discussions will be documented in a report.

“A particularly interesting discussion will be on so-called “dark and quiet skies,” meaning keeping the skies clear for radio and optical astronomy, for amateur star-gazing, and to preserve the legends, myths, and religions that reside in the visible stars,” Gremban said. “There are a number of designated dark sky locations around the world, but that won’t matter if brightly reflecting satellites obscure the constellations.”

Registration for the conference is now open, and a remote option will be available. Additionally, CLE credits for Colorado attorneys are pending. Visit the Silicon Flatirons website for more details.
