THEMIS Image of the Day, July 10, 2014. Today’s VIS image shows more north polar dunes. More THEMIS Images of the Day by geological topic.
THEMIS Image of the Day, July 8, 2014. Today’s image is part of Olympia Undae, but unlike yesterday’s image, there is more topography in this region. The dunes are forming in the lower elevations, but can migrate up the sides … Continue reading
THEMIS Image of the Day, July 1, 2014. This VIS image shows Hyperborei Cavi — the low regions on the right side of the image. Dunes are found both in the lows and on the higher region on the left … Continue reading

THEMIS Image of the Day, June 5, 2014. Now that summer has arrived in the northern hemisphere of Mars, the dunes near the polar cap have shed all their winter frost. More THEMIS Images of the Day by geological topic.
THEMIS Image of the Day, May 14, 2014. A sand sheet with surface dune forms partly surrounds the central peak of this unnamed crater near the north pole. More THEMIS Images of the Day by geological topic.
THEMIS Image of the Day, May 8, 2014. Today’s VIS image shows part of Aspledon Undae, one of several dune fields near the north pole. The term Undae means dunes. More THEMIS Images of the Day by geological topic.
Olympia Undae is a large field of sand dunes surrounding Mars’ North Polar ice cap. Because of the high latitude of the dunes, they are covered with water and carbon dioxide frost in the winter and are poorly illuminated. They … Continue reading
