The German Aerospace Centre (DLR) invites you to take a virtual flight over Mars; it has published a video showing the Martian region Xanthe Terra from above. It was created using data from the European Mars Express probe.

The flight begins in the highland region of Xanthe Terra near the Martian equator. It follows the Shalbatana Vallis into the Chryse Planitia plain and from there through the Simud Vallis into the rugged landscapes of Hydraotes Chaos, DLR announced. The dichotomy boundary of the planet is also crossed in the process. There, an older, crater-strewn highland in the south merges into a younger lowland in the north.
The Shalbatana Vallis is an outflow channel over 1,300 kilometers long. Such channels were probably formed by huge floods triggered when large quantities of ice suddenly melted due to volcanic activity underground.

The images were taken by a DLR camera
The data for the almost four-minute video was created by the DLR High-Resolution Stereo Camera (HRSC) experiment. It is installed on the European Space Agency's (ESA) Mars Express probe, which was launched in June 2003 and has been orbiting Mars since December 2003.
The video was created from an image mosaic consisting of HRSC images. The mosaic was combined with topography data from a digital terrain model (DTM) to create a three-dimensional landscape. According to DLR, 50 individual images were calculated for each second of the film, following a predefined camera path. Structures were vertically exaggerated three times for the animation. Atmospheric effects such as clouds and haze were added to disguise the boundaries of the terrain model.
