Fall in the Hellas Basin. We took this image during the Martian fall in the Southern Hemisphere, in the giant impact crater known as Hellas Basin where small boulders cast long shadows. The long shadows emphasize small scale topographic features. … Continue reading
Defrosting dunes. They’re melting! They’re melting! Beautiful Mars series.
This image shows a dune field in Chasma Boreale, which is a large trough that cuts into the North Polar ice cap. Some of the dunes in this image are quite long and sinuous with a slight bulge at one … Continue reading
THEMIS Image of the Day, September 18, 2017. Siton Undae is a large dune field located in the northern plains near Escorial Crater. Siton Undae is west of the crater and is one of three dune fields near the crater. … Continue reading
It is spring in the Northern hemisphere when we took this image. Over the winter, snow and ice have inexorably covered the dunes. Unlike on Earth, this snow and ice is carbon dioxide, better known to us as dry ice. … Continue reading
Frosted valleys. Beautiful Mars series.
THEMIS Image of the Day, June 26, 2017. Do you see what I see? Don’t be afraid, but it looks like a ghost! (THEMIS Art #133) More THEMIS Images of the Day by geological topic.
THEMIS Image of the Day, June 9, 2017. Today’s VIS image shows more of the south polar cap at the end of southern summer. More THEMIS Images of the Day by geological topic.
THEMIS Image of the Day, June 8, 2017. This VIS image of the south pole was taken at the end of summer. Frost will soon start to form as the season transitions into fall. Fall in the southern hemisphere means … Continue reading
This is the location with the most impressive known gully activity in the Northern hemisphere. Gullies are active in the winter due to carbon dioxide frost, but northern winters are shorter and warmer than southern winters, so there is less … Continue reading
