The Earth Surface Mineral Dust Source Investigation, EMIT, is a Visible-Shortwave Infrared imaging spectrometer that will launch to the International Space Station in 2022.  EMIT aims to map the surface composition of Earth’s mineral dust forming regions,  improving our knowledge of mineral dust composition and its effects on global radiative forcing.  EMIT incorporates unique innovations including: a Dyson optical design with only five components between the aperture and detector, high photon throughput and spectral uniformity; automatic onboard cloud recognition providing a 50% increase in mission data yield; and an open source science data system with quantified uncertainties delivered at every product level.   This talk will describe the mission objectives, measurement method, data analysis, and anticipated products.
