On its 25th resupply mission to the ISS, Space X’s Dragon capsule will include NASA’s Earth Surface Mineral Dust Source Investigation, also known as EMIT. EMIT has a imaging spectrometer which will measure dust-source-compositions around the globe!
More than a billion metric tons of mineral dust from deserts and dry regions is carried into the atmosphere by strong winds each year. Darker minerals absorb sunlight – warming the Earth – while lighter-colored minerals reflect sunlight – cooling the Earth. EMIT will help scientists by accurately mapping the areas that produce each type of dust – deepening our understanding of Earth’s system.
