Simulating the evolution of Mars volcano Olympus Mons
Scientists have succeeded in creating a model simulating the formation of mysterious structures on the surface of the Mars volcano, Olympus Mons. The research project is based on image data of the High Resolution Stereo Camera (HRSC) that is installed on the European Mars Express spacecraft, which has been orbiting the red planet since December 2003. Using the camera images, the scientists in the Planetary Sciences and Remote Sensing group generated a mosaic and a terrain model of the Olympus Mons volcano. The image data show that the volcano shield is shaped in the form of arched terraces and the foot of the otherwise very flat volcano drops steeply. The origin of the terraces and the steep slope of Olympus Mons were discussed heatedly in previous publications.
