THEMIS: South polar cap layers
THEMIS Image of the Day, March 3, 2017. This VIS image shows the layering of the South Polar cap of Mars. The image is located at the margin between the cap ice and the surrounding plains (bottom of image). More … Continue reading

THEMIS: Pages from the south polar climate history book
THEMIS Image of the Day, February 22, 2017. Today’s VIS image shows part of the south polar cap. It is now summer in the region and the surface frosts are gone. The layers of ice comprising the cap are now … Continue reading

HiRISE: Wide, branching channels
Southern spring on Mars brings sublimation of the seasonal dry ice polar cap. Gas trapped under the seasonal ice sheet carves channels on its way to escaping to the atmosphere. At this site, the channels are wider than we see … Continue reading

3D images reveal Mars polar ice cap features
Three-dimensional subsurface images are revealing structures within the Martian polar ice caps, including previously obscured layering, a larger volume of frozen carbon dioxide contained in the south polar cap, and bowl-shaped features that may be buried impact craters within both … Continue reading

HiRISE: Coolest landscape on Mars or Earth
Many Martian landscapes contain features that are familiar to ones we find on Earth, like river valleys, cliffs, glaciers and volcanos. However, Mars has an exotic side too, with landscapes that are alien to Earthlings. This image shows one of … Continue reading

Hunting ice cap ‘spiders’ through citizen science
Ten thousand volunteers viewing images of Martian south polar regions have helped identify targets for closer inspection, yielding new insights about seasonal slabs of frozen carbon dioxide and erosional features known as “spiders.” From the comfort of home, the volunteers … Continue reading

THEMIS: Swiss-cheese terrain on south polar cap
THEMIS Image of the Day, October 4, 2016. This VIS image of the South Polar cap shows several different surface textures. It appears that the circular depressions (which look like swiss cheese) alter with time, appearing to lose the circular … Continue reading

THEMIS: South polar ice cap textures
THEMIS Image of the Day, September 27, 2016. This VIS image shows part of the South Polar cap. As spring moves into the summer the surface frost is reduced and the surface texture of the ice is revealed. More THEMIS … Continue reading
