And what details! This image, acquired by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter on Jan. 24, 2014, shows rippled dunes in Mars’ southern hemisphere, coated with a fall dusting of seasonal carbon dioxide frost. With the Sun just five degrees above the horizon, the surface detail captured by HiRISE is simply exquisite.

The original image resolution is just over 50 cm per pixel, so details about 151 cm (5 feet) wide are resolved. See the full image area here, and view the original post on the University of Arizona’s HiRISE site here.
MRO launched on August 12, 2005, and has been in orbit around Mars since March 2006. It is currently in its second Extended Mission exploring the surface of Mars.
