Tharsis - Mars Express
Widefield image of the Mars' Tharsis volcanic region. Several of the largest known volcanoes in the Solar System are located within the frame. These include Alba Mons (top left), Olympus Mons (bottom left), Ascraeus Mons (center right), Pavonis Mons (right). Several smaller volcanoes are also visible in the region.
The large canyon systems of Noctis Labyrinthus and Valles Marineris can be seen at top right. These systems formed as deep fractures in the Martian crust. These fractures are due to the immense weight of the Tharsis volcanoes and their associated lava flows on the crust.
This image was taken on October 12, 2017 during Mars Express' 18,444th orbit of Mars.
