Surface Biology and Geology (SBG) is a Directed Observable mission from the 2017 Decadal Survey. A wide swath visible-to-shortwave infrared imaging spectrometer and a wide-swath thermal imager will provide mow-the-lawn global coverage of Earth’s terrestrial, coastal and open ocean surfaces as well as atmospheric conditions. SBG addresses decadal survey science and applications focal areas including snow, coastal ecosystems, vegetation health, volcanic activity, and mineralogy. Launch readiness date is approximately late 2020s.
