The Earth Surface Mineral Dust Source Investigation (EMIT) by NASA.

NASA's Earth Surface Mineral Dust Source Investigation (EMIT) mission, operating from the International Space Station, will thoroughly assess the mineral makeup of Earth's mineral dust source regions to aid researchers in understanding how dust blown by the wind can either heat or cool our planet as it travels through the atmosphere.Dust can have an impact on cloud formation, air quality, and human health in addition to potentially impacting warming on regional and global scales. Dust has the ability to cause microscopic algae blooms when it is dumped in the water. EMIT will employ an image spectrometer to measure the visible and infrared light reflected from surfaces below in order to perform these measurements. EMIT was launched in 2022 as part of SpaceX's 25th commercial resupply services mission for NASA from the Kennedy Space Centre in Florida.
