Engineers and technicians at NASA's Jet Propulsion Laboratory in Southern California assemble components of the Earth Surface Mineral Dust Source Investigation (EMIT) mission instrument in December 2021. The upper portion consists of EMIT's optical subsystem, including a telescope and imaging spectrometer, while the baseplate below holds electronics. EMIT will collect measurements of 10 important surface minerals – hematite, goethite, illite, vermiculite, calcite, dolomite, montmorillonite, kaolinite, chlorite, and gypsum – in arid regions between 50-degree south and north latitudes in Africa, Asia, North and South America, and Australia. The data EMIT collects will help scientists better understand the role of airborne dust particles in heating and cooling Earth's atmosphere on global and regional scales. https://photojournal.jpl.nasa.gov/catalog/PIA25146
