THEMIS Image of the Day, November 14, 2017. This image of Moreux Crater shows part of the central peak and fields of sand dunes on the crater floor surrounding the peak. The lower elevations of the peak are visible on the top left side of the image, with the highest elevations just off the image edge. The part of the peak with a pitted surface texture has been interpreted to be created by glacial flows. Moreux Crater is located in northern Arabia Terra and has a diameter of 138 kilometers (86 miles).
NASA’s Mars Odyssey spacecraft has spent over 15 years in orbit around Mars, circling the planet more than 69,000 times. It holds the record for longest working spacecraft at Mars. THEMIS, the IR/VIS camera system, has collected data for the entire mission and provides images covering all seasons and lighting conditions.
Over the years many features of interest have received repeated imaging, building up a suite of images covering the entire feature. From the deepest chasma to the tallest volcano, individual dunes inside craters and dune fields that encircle the north pole, channels carved by water and lava, and a variety of other feature, THEMIS has imaged them all.
For the next several months the Image of the Day will focus on the Tharsis volcanoes, the various chasmata of Valles Marineris, and the major dunes fields. We hope you enjoy these images!
