This image could be the photographed close-up of a macchiato - foamy bright milk swirling at the top of a cup with the rich undercurrent of aromatic coffee steaming below. In actuality, this is Mars' frozen north pole, created with observational data from the European Space Agency's long-lived orbiter, Mars Express - where swirling ice looks like foam and the ruddy iron oxide-rich dust appears as rich coffee.
Assembled from observations taken during 32 overflights of the north pole between 2004 and 2010 and covering a whopping one million square kilometers, a newly released mosaic (below) highlights the Red Planet's magnificently-structured ice cap that is shaped by climatic cycles and molded by the planet's perpetual winds.
By combining this mosaic with data from the Mars Orbiter Laser Altimeter (MOLA) on board NASA's Mars Global Surveyor spacecraft (which studied Mars from 1997 to 2006), ESA scientists were able to create a "perspective" or "oblique" view of the ice cap, adding depth to the canyons (pictured top). If you looked out of the window from a high-altitude aircraft (or spacecraft in low-Mars orbit) flying over the north pole, this is what you'd see.

Mars Express is no stranger to Mars' north polar ice cap and the mission has added a wealth of information to our understanding of how the region is shaped.
