In this DLR webcast, Ernst Hauber of the Institute of Planetary Research talks about the start of the mission and about the study of our neighbouring planet Mars. The planetary geologist coordinates the recording of images by the high-resolution HRSC stereo camera. This camera records images of Mars in 3-D and colour. During an overflight, the camera records images of an area from multiple visual angles. Ernst Hauber analyses the images. In his conversation with DLR reporter Sven Oswald, Hauber also discusses the most important results of Mars research so far, especially the evidence of water on the planet.
