Chasma Boreale, MarsChasma Boreale, a long, flat-floored
valley, cuts deep into Mars' north polar icecap. Its walls rise about
4,600 feet, or 1,400 meters, above the floor. Where the edge of the ice
cap has retreated, sheets of sand are emerging that accumulated during
earlier ice-free climatic cycles. Winds blowing off the ice have pushed
loose sand into dunes and driven them down-canyon in a westward
direction.
This scene combines images taken during the period from December 2002 to February 2005 by the Thermal Emission Imaging System instrument on NASA's Mars Odyssey
was part of a special series of images marking the orbiter as the
longest-working Mars spacecraft in history.
