Syrtis Major features

Syrtis Major is a volcanic province on Mars. This image from the High-Resolution Stereo Camera on ESA’s Mars Express orbiter shows lava flows in box 1. Filled craters and partly filled craters can be seen in box 2. The prevailing wind direction can be judged from the dispersal of the lighter-toned material. The smaller craters illustrate this clearly. The largest crater in the picture, highlighted in box 3, has a small central peak and contains a small dune field of darker-toned dunes. ESA’s Mars Express collected the data for this image on 8 June 2011 during orbit 9487. The image has a ground resolution of approximately 19 m per pixel.
