This body is home to regions known as "Barnacle Bill" and "Shark" which contain fine-grained quartzite minerals similar to andesite. Piqueux theorized that this body's dark "spider" regions were the result of geyser activity driven by subterranean sublimation of atmospheric gases. This body saw the formation of many lava plains during its Hesperian Geological Epoch, while its earlier (*) Noachian epoch is characterized by heavy bombardment. Perchlorate and calcium carbonate were determined to be present in this body's soil by the Phoenix Mission in 2008, and other explorations of this body include the two Viking missions. This body's massive plateau, the Tharsis Bulge, is located just west from the solar system's largest canyon, Valles Marinaris, and famously contains the solar system's tallest mountain, the volcano Olympus Mons. Recently explored by Spirit and Opportunity, FTP, name this body orbited by Phobos and Deimos, the fourth planet from the sun.
