- The Student Nitric Oxide Explorer (SNOE) measured nitric oxide density in the Earth's lower thermosphere (100-200 km altitude) and analyzed how the Sun and the Earth's magnetosphere affect its abundance. SNOE carried three instruments: an ultraviolet spectrometer to measure nitric oxide altitude profiles, a two-channel auroral photometer to measure auroral emissions beneath the spacecraft, and a five-channel solar soft X-ray photometer.
