Sight-seeing in the 21st century -- ices, sand, water, and dust in motion on Mars

Humankind's earnest reconnaissance of Mars, made possible by advances in our technology, has progressed significantly over the past 150 years. Early ideas of vibrant macroscopic life on Mars in the late 19th and early 20th centuries gave way to a perception of a barren desert world 

Remote sensing survey of Valles Marineris: insights into magmatic and sedimentary processes on Mars

valles marinerisValles Marineris is a unique vertical section through the uppermost kilometers of the martian crust; its location, east of Tharsis bulge, and its water-related history are responsible for a great diversity of rock types in this area. High resolution morphological (HiRISE) and mineralogical (CRISM) data from the MRO mission (NASA, 2006) available over the area were investigated.

Free Samples from Mars

martian meteoriteIn the late 70's meteoriticists began to speculate that some oddball meteorites might be from Mars. These meteorites looked more like terrestrial rocks than meteorites, but they were seen to fall- Chassigny in 1815, Shergotty in 1865, and Nakhla in 1911. The big question, how these SNC meteorites got here, seemed to be solved by the "spall mechanism", a combination of high velocity and low shock pressure.
