Images taken by the High Resolution Stereo Camera (HRSC) aboard ESA's Mars Express spacecraft, show a large depression called Iani Chaos and the upper reaches of a large outflow channel called Ares Vallis.
Image strips were taken in October 2004, during three orbits from a 350-kilometre altitude, with a resolution of 15 metres per pixel. The Iani Chaos depression – 180 kilometres long and 200 kilometres wide – is connected to the beginning of Ares Vallis by a 100-kilometre wide transition zone. Read more and view images.
