Mars on camera
Three papers in this issue present the evaluation of the first six months of data from the high-resolution stereo camera on board ESA's Mars Express probe. The images reveal evidence for a frozen sea similar in area and depth to the North Sea on Earth, and some 5 million years old. Other surface features suggest recent climate change, as evidenced by snow, ice and glacial flow at mid-latitudes, and explosive volcanism 350 million years ago.
