SAGE IV Pathfinder

NASA TechPort and Langley sources describe SAGE IV Pathfinder as a completed Center Innovation Fund project that developed a compact solar-occultation imaging instrument for sustained ozone, aerosol, and trace-gas measurements. The shoebox-sized CubeSat-compatible design captures the full solar disk in one image, reducing pointing complexity and cost while preserving SAGE-quality atmospheric observations and enabling a sustainable long-term climate data record.
