Tharsis, extensive volcanic province on Mars that contains three of the planet’s most massive volcanoes. Olympus Mons is the highest mountain in Mars and tallest mountain on any planet in the Solar System with 21,171 meters. Ascraeus Mons est le plus septentrional des trois grands volcans formant l'alignement de Tharsis Montes — les deux autres sont Pavonis Mons au centre et Arsia Mons au sud ; le groupe d'Uranius prolonge cet alignement au nord. Arsia Mons / ˈɑːrsiə ˈmɒnz / is the southernmost of three volcanoes (collectively known as Tharsis Montes) on the Tharsis bulge near the equator of the planet Mars.

Olympus Mons lies off image to the upper left. [7] The southwest-northeast orientation of the aprons matches the orientation of the Tharsis Montes, suggesting that a major fissure or rift in the Martian crust is responsible for the orientation of both the aprons and the Tharsis Montes chain. This means you … Ascraeus Mons é o vulcão mais setentrional de um grupo de três conhecido como Tharsis Montes na região montanhosa de Tharsis próxima oa equador do planeta Marte.Ao seu sul fica o Pavonis Mons, e ao sul deste o Arsia Mons.O maior vulcão do sistema solar, o Olympus Mons, fica a noroeste.. O Ascraeus Mons é considerado um dos vulcões mais altos de Marte. (1986). The volcano was originally called North Spot[2] because it was the northernmost of only four spots visible on the surface due to a global dust storm that was then enshrouding the planet. Many of the lava flows have levees along their margins. Ascraeus Mons /əˈskriːəs ˈmɒnz/ is a large shield volcano located in the Tharsis region of the planet Mars. Volcanoes are formed when the hot molten lava, ash, and gases trapped inside the Earth’s surface find an outlet, through a fissure or opening in a planet’s crust. The flank terraces may be due to compressional failure of the volcano, flexing of the underlying lithosphere due to the volcano's massive weight, cycles of magma chamber inflation and deflation, or shallow gravitational slumping. Much of Tharsis is covered with volcanic plains, collectively called Tharsis The presence of the lava aprons causes some disagreement in the actual dimensions of the volcano. The volcano is located in the southeast-central portion of the Tharsis quadrangle at 11.8°N, 255.5°E in Mars' western hemisphere. Ascraeus stands at an impressive 59,793 feet above datum with a diameter of about 250 miles. Some may be collapsed lava tubes. Pavonis Mons Elysium Alba Patera lowest point in Valles Marineris Hellas Basin (Note: Olympus Mons has been widely reported as 17 miles [27 km] in height, but the final MOLA data gives the lower value given here.) The massive Martian mountain towers high above the surrounding plains of the red planet, and may be biding its time until the next eruption. With the release of Rick Wakeman’s new studio album, The Red Planet, due on August 28, the keyboard legends has released the first single to be taken from the album, entitled “Ascraeus Mons”. The Tharsis region is thousands of kilometers across and averages nearly 10 km (33,000 ft) above the mean elevation of the planet. ; Harris, A.J.L. R.A. Exposition Press.

This VIS image shows a portion of the northern flank of Ascreaus Mons. Latitude 17.6N, Longitude 262.9E. [14] These rimless pit craters are believed to form by collapse of surface material into a subsurface void created either by a dike or lava tube. [20][21] Earth-based radar studies show that Ascraeus Mons has a higher radar echo strength than other volcanic structures on the planet. The lava plains northwest of Ascraeus Mons are notable for having two dark collapse pits photographed by the HiRISE camera on the Mars Reconnaissance Orbiter (MRO) in November 2010 (pictured in gallery below).

It is the northernmost and tallest of three shield volcanoes collectively known as the Tharsis Montes. During its many years in Saturn orbit, NASA’s Cassini spacecraft discovered previously unknown moons, solved mysteries about known ones, studied their interactions … Like most of the Tharsis region, Ascraeus Mons has a high albedo (reflectivity) and low thermal inertia, indicating that the volcano and surrounding areas are covered with large amounts of fine dust. Ascraeus Mons. L'âge relevé sur les terrains constituant le fond du système assez complexe de caldeiras de ce volcan s'échelonne entre 800 Ma et 100 Ma, l'activité volcanique semblant s'être poursuivie un peu au-delà sur les flancs.

To its north is Pavonis Mons, and north of that is Ascraeus Mons. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. [33] During periods of high obliquity (axial tilt) the polar regions receive higher levels of sunlight. The volcano is located in the southeast-central portion of the Tharsis quadrangle at 11.8°N, 255.5°E in Mars' western hemisphere. The volcano's location corresponds to the classical albedo feature Ascraeus Lacus. Partially collapsed lava tubes are visible as chains of pit craters. Towering 16 miles (25 km) above the surrounding plains, volcano Ascraeus Mons pokes above the cloud deck near the western or limb. First Descent into Devil's Throat. Ascraeus Mons, Mars – 14.9 km (9.3 mi) Ascraeus Mons is the second largest mountain on planet Mars (after Olympus Mons) reaching about 15 km from its base. If the dates are valid, then Ascraeus Mons may have been active through most of Mars' history. Details in rock and dust are seen when this image is examined at its full, 1.5 meters (5 ft) per pixel resolution. In that particular region of Mars, however, Olympus Mons is hardly alone. Both moons were discovered in 1877 and were named after brothers from Greek mythology. This VIS image shows the eastern flank of Ascraeus Mons. [4] Gulick, V. (2010).

At left, from top to bottom, are the three 25 km high volcanic shields, Ascraeus Mons, Pavonis Mons, and Arsia Mons. The chains of oval depressions typically form when a subsurface void is filled by collapse of the 'roof' above it. The bottoms of both pits contain sediments and large boulders. Ellison, D.J.

By examining the morphologies of lava flow structures on Ascraeus Mons, geologists are able to calculate the rheological properties of the lava and estimate the rate at which it poured out during eruption (effusion rate). During its many years in Saturn orbit, NASA’s Cassini spacecraft discovered previously unknown moons, solved mysteries about known ones, studied their interactions … Ascraeus Mons is surrounded by lava flow plains that are mid to late Amazonian in age. Ascraeus Mons; Other planets and moons.

Hawaii, the Moon, elsewhere on Mars) and morphologic features by multiple researchers has led to the conclusion that a volcanic origin is most probable. Ce volcan est également le plus ancien de Tharsis Montes : il se serait formé au début de l'Hespérien, avant 3,6 Ga, et son activité se serait prolongée à l'Amazonien, jusqu'à seulement 50 Ma[2]. Dark Rimless Pits in the Tharsis Region (ESP_019997_1975). Arsia Mons. Olympus Mons is 2.4 times taller than Earth’s highest Mount Everest.
