Mars Odyssey All Stars - Polar Dunes
A sea of dark dunes, sculpted by the wind into long lines, surrounds the northern
polar cap covering an area as big as Texas. This image covers an area 30
kilometers (19 miles) wide.
This scene combines images taken during the period from December 2002 to
November 2004 by the Thermal Emission Imaging System instrument on NASA's
Mars Odyssey orbiter. It is part of a special set of images marking the occasion of
Odyssey becoming the longest-working Mars spacecraft in history. The pictured
location on Mars is 80.3 degrees north latitude, 172.1 degrees east longitude.
