THEMIS Image of the Day, February 21, 2017. Over the course of the Odyssey mission, the spacecraft has flown covering the surface at many different times of local day. Right now Odyssey is looking down along the day/night terminator, seeing dawn and dusk. One of the benefits from imaging at these times of day (and lower sun angles) is seeing shadows. This VIS image shows the sunrise shadow of the crater rim on the crater floor.
