Paul Mirel, the creator and lead engineer of STELLA at NASA Goddard Space Flight Center, developed these instruments to make remote sensing science accessible through commercially available components. The instruments cost under $200 and measure light spectra across visible and near-infrared wavelengths, demonstrating the same principles used by NASA satellite missions.
The paper documents implementations across multiple settings, showing how STELLA technology creates pathways for understanding NASA Earth science missions. Dr. Craig Kohn at Waterford Union High School has integrated STELLA into agricultural science curricula, where students analyze vegetation health using NDVI measurements to compare different farming practices. This work connects classroom learning to the same spectral analysis methods used by NASA’s Landsat program.
Michael Taylor from NASA Goddard Space Flight Center has led workshops demonstrating how STELLA instruments help people understand NASA’s Earth observation capabilities. The technology provides hands-on experience with remote sensing principles while developing technical skills applicable to Earth science careers.
The research shows that STELLA instruments enable scientific measurements at scales not practical with expensive professional equipment. By making remote sensing accessible to broader communities, the technology expands participation in scientific research while building understanding of NASA mission applications.
Karen Karker at SUNY Environmental Science and Forestry has used STELLA in outreach programs, engaging participants from elementary through high school ages in spectral analysis activities that demonstrate how sensors can detect light invisible to human eyes. Her work shows how STELLA creates early exposure to NASA Earth science concepts.
The paper documents how university students gain comprehensive research experience through STELLA projects, developing skills in electronics assembly, programming, data analysis, and scientific methodology. These experiences prepare students for careers supporting NASA missions and Earth science applications.
The study demonstrates that STELLA’s open-source design supports global implementation while building technical workforce capabilities aligned with NASA’s Earth observation objectives. The research shows how the technology creates pathways between community engagement and the technical skills needed for NASA mission support.
The publication provides evidence of how accessible instrumentation can simultaneously advance scientific capabilities and develop workforce expertise essential for NASA’s Earth science and space exploration programs. The research establishes STELLA as a model for community-based technology development that supports NASA’s strategic objectives while expanding access to remote sensing science.
