Enceladus is the sixth-largest moon of Saturn and the 19th-largest in the Solar System. It is about 500 kilometers in diameter, about a tenth of that of Saturn's largest moon, Titan. It is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System. Consequently, its surface temperature at noon reaches only −198 °C, far colder than a light-absorbing body would be. Despite its small size, Enceladus has a wide variety of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrain.
In planetary nomenclature, a fossa is a long, narrow depression (trough) on the surface of an extraterrestrial body, such as a planet or moon. The term, which means "ditch" or "trench" in Latin, is not a geological term as such but a descriptor term used by the United States Geological Survey (USGS) and the International Astronomical Union (IAU) for topographic features whose geology or geomorphology is uncertain due to lack of data or knowledge of the exact processes that formed them. Fossae are believed to be the result of a number of geological processes, such as faulting or subsidence. Many fossae on Mars are probably graben.
Sarandib Planitia is a region of relatively un-cratered terrain on Saturn's moon Enceladus. It is located at 4.4° North Latitude, 298.0° West Longitude and is approximately 200 km across. From Voyager images, Sarandib Planitia is considered part of either the ridged plains unit or smooth plains unit of Enceladus, thought to be the youngest terrain on Enceladus. In more recent Cassini images, Sarandib is resolved into a region of relatively low ridges, with a band of rifted terrain cutting through the middle from northwest to southeast. In addition, a series of long-wavelength compression ridges are seen in the western portion of Sarandib Planitia, reminiscent of banded terrain on Europa, like Astypalaea Linea. Only approximately 20 craters larger than 1 kilometer across have been found in Sarandib, demonstrating the youthful age of the region.
Samarkand Sulci is a region of grooved terrain on the surface of Saturn's moon Enceladus. The feature is centered at 30.5° North Latitude, 326.8° West Longitude, and is approximately 383 kilometers long. Samarkand Sulci consists of three parts. The southern and eastern extensions bound Sarandib Planitia on its western and northern sides, respectively. The northern portions extends into a region of cratered terrain.
Ahmad is a crater in the northern hemisphere of Saturn's moon Enceladus. Ahmad was first discovered in Voyager 2 images but was seen at much higher resolution, though near the terminator, by Cassini. It is located at 58.8° North Latitude, 311.6° West Longitude and is 18.7 kilometers across. The western portion of the crater is largely absent, either buried or disrupted by the eastern margin of Samarkand Sulci. A large, dome-like structure occupies the interior of the crater, caused by infill of material from Samarkand Sulci or from viscous relaxation.
Peri-Banu is a crater in the northern hemisphere of Saturn's moon Enceladus. Peri-Banu was first discovered in Voyager 2 images but was seen at much higher resolution, though near the terminator, by Cassini. It is located at 62° North Latitude, 322.9° West Longitude and is 18 kilometers across. The western portion of the crater is largely absent, either buried or disrupted by the eastern margin of Samarkand Sulci. A large, dome-like structure occupies the interior of the crater, caused by infill of material from Samarkand Sulci or from viscous relaxation.
Julnar is a crater in the northern hemisphere of Saturn's moon Enceladus. Julnar was first discovered in Voyager 2 and has only been seen at comparable resolution by Cassini. It is located at 52.8° North Latitude, 350.0° West Longitude and is approximately 19 kilometers across.
Salih is a small crater near the sub-Saturnian point of Saturn's moon Enceladus. Salih was first discovered in images taken by the Voyager 2 spacecraft. It is located at 6.5° South Latitude, 0° West Longitude and is 4 kilometers across. Available images of this crater have too low resolution to determine anything about the geology of this crater.
Diyar Planitia is a region of relatively un-cratered terrain on Saturn's moon Enceladus. Its location is 0.5° North Latitude, 239.7° West Longitude while its being approximately 311 km across.
Harran Sulci is a region of grooved terrain on the surface of Saturn's moon Enceladus. The feature is centered at 26.7° North Latitude, 237.6° West Longitude and is approximately 276 kilometers long. Harran Sulci bounds Diyar Planitia to the north and east.
Amazonis Planitia is one of the smoothest plains on Mars. It is located between the Tharsis and Elysium volcanic provinces, to the west of Olympus Mons, in the Amazonis and Memnonia quadrangles, centered at 24.8°N 196.0°E. The plain's topography exhibits extremely smooth features at several different lengths of scale. A large part of the Medusae Fossae Formation lies in Amazonis Planitia.
The tiger stripes of Enceladus consist of four sub-parallel, linear depressions in the south polar region of the Saturnian moon. First observed on May 20, 2005, by the Cassini spacecraft's Imaging Science Sub-system (ISS) camera, the features are most notable in lower resolution images by their brightness contrast from the surrounding terrain. Higher resolution observations were obtained by Cassini's various instruments during a close flyby of Enceladus on July 14, 2005. These observations revealed the tiger stripes to be low ridges with a central fracture. Observations from the Composite Infrared Spectrometer (CIRS) instrument showed the tiger stripes to have elevated surface temperatures, indicative of present-day cryovolcanism on Enceladus centered on the tiger stripes.
Labtayt Sulci is a system of deep fractures on Saturn's moon Enceladus. Labtayt Sulci was first seen in low-resolution Voyager 1 images, but was observed in much more detail by the Cassini spacecraft during its February 2005 flyby of Enceladus. It is centered at 28.0° South Latitude, 284.0° West Longitude and is approximately 162 kilometers long, 4 kilometers wide, and 1 kilometer deep. The association between a cusp along the South Polar terrain boundary and Labtayt suggests that the fracture was forced open by thrust faulting where the fracture intersects with Cashmere Sulci.
The Diacria quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The quadrangle is located in the northwestern portion of Mars' western hemisphere and covers 180° to 240° east longitude and 30° to 65° north latitude. The quadrangle uses a Lambert conformal conic projection at a nominal scale of 1:5,000,000 (1:5M). The Diacria quadrangle is also referred to as MC-2. The Diacria quadrangle covers parts of Arcadia Planitia and Amazonis Planitia.
The Amazonis quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Amazonis quadrangle is also referred to as MC-8.
The Tharsis quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Tharsis quadrangle is also referred to as MC-9 . The name Tharsis refers to a land mentioned in the Bible. It may be at the location of the old town of Tartessus at the mouth of Guadalquivir.
Fretted terrain is a type of surface feature common to certain areas of Mars and was discovered in Mariner 9 images. It lies between two different types of terrain. The surface of Mars can be divided into two parts: low, young, uncratered plains that cover most of the northern hemisphere, and high-standing, old, heavily cratered areas that cover the southern and a small part of the northern hemisphere. Between these two zones is a region called the Martian dichotomy and parts of it contain fretted terrain. This terrain contains a complicated mix of cliffs, mesas, buttes, and straight-walled and sinuous canyons. It contains smooth, flat lowlands along with steep cliffs. The scarps or cliffs are usually 1 to 2 km high. Channels in the area have wide, flat floors and steep walls. Fretted terrain shows up in northern Arabia, between latitudes 30°N and 50°N and longitudes 270°W and 360°W, and in Aeolis Mensae, between 10 N and 10 S latitude and 240 W and 210 W longitude. Two good examples of fretted terrain are Deuteronilus Mensae and Protonilus Mensae.
