Feb. 3 (UPI) -- A new mosaic provided by ESA's Mars Express probe has offered a comprehensive view of Mars' unique polar ice cap. As revealed by the new composite image, the permanent fixture of ice on Mars' north pole is marked by a swirl of deep troughs and canyons.
The mosaic is an amalgamation of 32 image surveys executed by Mars Express between 2004 and 2010. The surveys imaged a total of approximately 380,000 square miles.
