A planetary landscape

"This image taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows the depression of Juventae Chasma, cut into the plains of Lunae Planum on Mars.

"In the north-eastern part of the scene, there is a mountain composed of bright, layered material. This mountain is approximately 2500 metres high, 59 kilometres long and up to 23 kilometres wide."
