As an undergraduate researcher, Gael Gonzalez is already contributing to the future of space-based astronomy. Supported by a Sigma Xi Grants in Aid of Research (GIAR) award, Gonzalez is working on the development of a CubeSat—a small, cube-shaped microsatellite— equipped with a specialized ultraviolet (UV) camera designed to study binary star systems. The multi-stage mission began with a precursor deployment to the International Space Station on April 8, 2026, with a full CubeSat launch planned in June in collaboration with partners in Chile. It's an ambitious project that bridges engineering, astrophysics, and experimental science.
At the heart of the mission is a goal to better understand how stars interact with their surrounding environments, particularly the planets that orbit them. By capturing photometric measurements of stellar activity in the UV spectrum, the CubeSat will help researchers refine models of stellar evolution, improve predictions about exoplanet atmospheric loss, and sharpen methods for identifying habitable zones. These questions build on a legacy of space-based observation, from Hubble Space Telescope—which revolutionized ultraviolet and visible-light astronomy—to more recent exoplanet-focused missions like Transiting Exoplanet Survey Satellite and James Webb Space Telescope.
Beyond the technical achievements, Gonzalez emphasizes how transformative the experience has been in shaping his identity as a researcher. “This project revealed how much behind-the-scenes work goes into science that often goes unnoticed,” he says. Equally important has been the hands-on nature of the project. From testing instrumentation to conducting performance analyses—such as simulating photometric drift caused by satellite motion—Gonzalez has gained a deeper appreciation for the meticulous effort required to bring a scientific concept to life.
The GIAR application process itself proved to be a critical learning opportunity. Writing and refining a proposal required him to translate complex scientific ideas into clear, persuasive language—an often overlooked but essential skill in research. Managing the awarded funds also introduced him to the practical realities of scientific work, including budgeting and prioritizing equipment needs. For future student applicants to the GIAR program, Gonzalez offers straightforward advice: “Fully understand every aspect of your project and be able to explain it to a wide range of audiences.” He also emphasizes the importance of collaboration and mentorship, adding that “curiosity, adaptability, and the ability to learn from challenges will help you grow as a researcher and make the most of the experience.”
Looking ahead, Gonzalez hopes to pursue a PhD in astrophysics and eventually work in a research role at NASA or a comparable institution. With a focus on space instrumentation and observational techniques, he aims to continue exploring stellar systems and exoplanets—fields that are rapidly expanding our understanding of the universe.
Gonzalez’s work exemplifies how early-career researchers can make meaningful contributions to science. With the support of programs like GIAR and a willingness to engage deeply with both the technical and communicative aspects of research, students like him are not just learning about science—they are actively shaping its future.
