Great tilt gave Mars a new face
The surface of the planet Mars tilted by 20 to 25 degrees 3 to 3.5 billion years ago. This was caused by a massive volcanic structure, the Tharsis volcanic dome, which is the largest in the Solar System. Because of … Continue reading
THEMIS: Ridges
THEMIS Image of the Day, February 9, 2016. This VIS image shows a small portion of the boundary region between Terra Sabaea and Utopia Planitia. The ridges and valleys in this image were likely created by tectonic faulting. There is … Continue reading

Two-faced Mars: Moon-size object hit south pole
The two hemispheres of Mars are more different from any other planet in our solar system. Non-volcanic, flat lowlands characterise the northern hemisphere, while highlands punctuated by countless volcanoes extend across the southern hemisphere. Although theories and assumptions about the … Continue reading

Debris aprons and valley fill hold ancient ice several hundred million years old
Along the edge of the crustal dichotomy, where the southern highlands step down onto the northern plains, lies a landscape of mesas, buttes, and valleys. Valleys appear choked with linear streams of debris, and on the flanks of many mesas … Continue reading
