Mars' Misty Mountains

Looking like Mars' version of Land of the Lost, these two mist-capped volcanoes are located in the Tharsis region in Mars' northern hemisphere. In this latest set of images released by the Mars Express team, a desolate looking landscape is softened by icy clouds drifting past the summit of Ceraunius Tholus, with the smaller Uranius Tholus to the right. No dinosaurs or Sleestaks are visible, but it looks like

could show up any minute!

The image was created from three different passes over the region by the spacecraft, and – surprisingly – during the middle orbit the clouds showed up. By the time Mars Express crossed again and took the final strip of data needed for this image, the clouds had long since dispersed and so there is a sharp line across them in the finished mosaic.

See below for a 3-D, perspective view of these two volcanoes.

Tharsis region -- often called the Tharsis Bulge -- is a continent-size volcanic plateau in Mars' western hemisphere. The region is home to the largest volcanoes in the solar system, including the three enormous shield volcanoes Arsia Mons, Pavonis Mons, and Ascraeus Mons. The tallest volcano on the planet, Olympus Mons, is way off to the western side of the Tharsis plateau.

See the Mars Express website

for more information and more images of Ceraunius Tholus and Uranius Tholus.

The images were taken during 2004-2006.
