When Mars was still young, more than four billion years ago, a large asteroid sailed out of the sky and slammed into an area known today as western Arabia Terra. The object hit hard enough that it blasted a basin at least 280 kilometers (175 miles) wide. The basin is now named Aram Chaos. As many millions of years passed, into this yawning bowl drifted sediments of many kinds - wind-blown dust, sand, and volcanic ash. The Martian climate was wetter then, so the crater-filling debris became...

Scientists using data from the HRSC experiment onboard ESA's Mars Express spacecraft have produced the first 'hiker's maps' of Mars. Giving detailed height contours and names of geological features in the Iani Chaos region, the maps could become a standard reference for future Martian research. The maps are known as topographic maps because they use contour lines to show the heights of the landscape. The contour lines are superimposed upon high-resolution images of Mars, taken by the...

ESA -- These 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 strips have then been matched to a mosaic that covers an area from 17.5º western longitude to 3º...
