DescriptionNorth Pole - Mars - Flickr - jccwrt.png
The Martian north pole as seen by Mars Express' HRSC instrument. This image was taken during Martian midsummer. At this time, the pole (located near the center of the ice cap) was experiencing the midnight sun. The constant daylight had melted much of the surface ice, leaving a remnant cap of water ice.
On the horizon, a large cloud can be seen. This is an orographic cloud produced by air rising up the slopes of Olympus Mons, causing the thin moisture in the atmosphere to condense out as a cloud.
This image was taken during Mars Express' 16,277th orbit of Mars, January 19, 2016.
