Fly over Xanthe Terra with Mars Express

ESA’s Mars Express takes us on another mesmerising flight over curving channels carved by water, islands that have resisted erosion, and a maze of hilly terrain.

Central to the tour is a 1300 km-long outflow channel called Shalbatana Vallis. It cascades down from the highland region of Xanthe Terra to the smoother lowlands of Chryse Planitia.

Billions of years ago, water surged through this channel, creating many of the features we see today.

The tour culminates in a spectacular view of a 100 km-wide impact crater, smashed out of Mars’s surface when it collided with a space rock.

Enjoy the flight, and be

Processing notes:

This film was created using the Mars Express High Resolution Stereo Camera Mars Chart (HMC30) data, an image mosaic made from single orbit observations of the mission’s High Resolution Stereo Camera (HRSC). The mosaic image, centred at 5°N/320°E, is combined with topography information from the digital terrain model to generate a three-dimensional landscape.

For every second of the movie, 50 separate frames are rendered following a predefined camera path in the scene. The vertical exaggeration used for the animation is three-fold. Atmospheric effects, like clouds and haze, have been added to conceal the limits of the terrain model. The haze starts building up at a distance of 250 km.

The HRSC camera on Mars Express is operated by the German Aerospace Center (DLR). The systematic processing of the camera data took place at the DLR Institute for Planetary Research in Berlin-Adlershof. The working group of Planetary Science and Remote Sensing at Freie Universität Berlin used the data to create the film.
