Glenelg, Mars
Glenelg, Mars (or ''Glenelg Intrigue'') is a location on Mars near the Mars Science Laboratory (''Curiosity rover'') landing site (Bradbury Landing) in Gale Crater marked by a natural intersection of three kinds of terrain. Name The location was named ''Glenelg'' by NASA scientists for two reasons: all features in the immediate vicinity were given names associated with Yellowknife in northern Canada, and Glenelg is the name of a geological feature there. Furthermore, the name is a palindrome, and as the ''Curiosity'' rover is planned to visit the location twice (once coming, and once going) this was an appealing feature for the name. The original Glenelg is a village in Scotland which on 20 October 2012 had a ceremony, including a live link to NASA, to celebrate their "twinning" with Glenelg on Mars. The trek to Glenelg will send the rover east-southeast of its landing site. One of the three types of terrain intersecting at Glenelg is layered bedrock, which is attractive as ...

Rocknest (Mars)
Rocknest is a sand patch on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons (Mount Sharp), in Gale crater on the planet Mars. The patch was encountered by the ''Curiosity'' rover on the way from Bradbury Landing to Glenelg Intrigue on September 28, 2012. The approximate site coordinates are: . The sand patch is downhill from a cluster of dark rocks. NASA determined the patch to be the location for the first use of the scoop on the arm of the Mars ''Curiosity'' rover. The Rocknest patch is about by . Discovery and material analysis On October 7, 2012, a mysterious bright object ( image), discovered in the sand at Rocknest, drew scientific interest. Several close-up picturesclose-up 1close-up 2 were taken of the object and preliminary interpretations by scientists suggest the object to be "debris from the spacecraft". Nonetheless, further images in the nearby sand have detected other bright particlesimageclose-up 1. These newly discovered objects are pres ...

Rock Outcrop
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonically active areas. In Finland, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to human excavations such as quarrying and build ...

Geology Of Mars
The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology. In planetary science, the term ''geology'' is used in its broadest sense to mean the study of the solid parts of planets and moons. The term incorporates aspects of geophysics, geochemistry, mineralogy, geodesy, and cartography. A neologism, areology, from the Greek word ''Arēs'' (Mars), sometimes appears as a synonym for Mars's geology in the popular media and works of science fiction (e.g. Kim Stanley Robinson, Kim Stanley Robinson's Mars trilogy). The term areology is also used by the Areological Society.

Composition Of Mars
The composition of Mars covers the branch of the geology of Mars that describes the make-up of the planet Mars. Elemental composition Mars is differentiated, which—for a terrestrial planet—implies that it has a central core made up of metallic iron and nickel surrounded by a less dense, silicate mantle and crust. Like Earth, Mars appears to have a molten iron core, or at least a molten outer core. However, there does not appear to be convection in the mantle. Presently Mars shows little geological activity. The elemental composition of Mars is different from Earth's in several significant ways. First, Martian meteorite analysis suggests that the planet's mantle is about twice as rich in iron as the Earth's mantle. The planet's distinctive red color is due to iron oxides on its surface. Second, its core is richer in sulphur. Third, the Martian mantle is richer in potassium and phosphorus than Earth's and fourth, the Martian crust contains a higher percentage of volatile ...

Bedrock
In geology, bedrock is solid Rock (geology), rock that lies under loose material (regolith) within the crust (geology), crust of Earth or another terrestrial planet. Definition Bedrock is the solid rock that underlies looser surface material. An exposed portion of bedrock is often called an outcrop. The various kinds of broken and weathered rock material, such as soil and subsoil, that may overlie the bedrock are known as regolith. Engineering geology The surface of the bedrock beneath the soil cover (regolith) is also known as ''rockhead'' in engineering geology, and its identification by digging, drilling or geophysics, geophysical methods is an important task in most civil engineering projects. Superficial deposition (geology), deposits can be very thick, such that the bedrock lies hundreds of meters below the surface. Weathering of bedrock Exposed bedrock experiences weathering, which may be physical or chemical, and which alters the structure of the rock to leave ...

Aeolis Quadrangle
The Aeolis quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Aeolis quadrangle is also referred to as MC-23 (Mars Chart-23). The Aeolis quadrangle covers 180° to 225° W and 0° to 30° south on Mars, and contains parts of the regions Elysium Planitia and Terra Cimmeria. A small part of the Medusae Fossae Formation lies in this quadrangle. The name refers to the name of a floating western island of Aeolos, the ruler of the winds. In Homer's account, Odysseus received the west wind Zephyr here and kept it in bags, but the wind got out. It is famous as the site of two spacecraft landings: the ''Spirit'' rover landing site () in Gusev crater (January 4, 2004), and the ''Curiosity'' rover in Gale Crater () (August 6, 2012). A large, ancient river valley, called Ma'adim Vallis, enters at the south rim of Gusev Crater, so Gusev Crater was believed to be an ancient lake bed. However, ...

Aeolis Palus
Aeolis Palus is a plain between the northern wall of Gale crater and the northern foothills of Aeolis Mons (Mount Sharp) on Mars. It is located at . The NASA Mars Science Laboratory mission landed the ''Curiosity'' rover on Aeolis Palus in August 2012. ''Curiosity'' spent two (Earth) years exploring the plain as it drove towards Aeolis Mons. The rover left the plain in September 2014 when it reached the mountain's foothills. Spacecraft exploration On August 5, 2012, at 10:32 p.m. PDT/mission time (August 6, 2012, at 5:32 UTC), mission control at JPL received a signal from the NASA ''Curiosity'' rover that it had successfully landed in "Yellowknife" ''Quad 51'' of ''Aeolis Palus''. The rover's mission is to explore the surface area of Gale Crater focusing first near its landing site on ''Aeolis Palus'' and then venturing into the nearby foothills of Aeolis Mons (unofficially, "Mount Sharp") to investigate its geological features and strata. On September 26, 2013, NASA sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Sharp
Mount Sharp, officially Aeolis Mons (), is a mountain on Mars. It forms the central peak within Gale (crater), Gale crater and is located around , rising high from the valley floor. Its ID in the United States Geological Survey's Gazetteer of Planetary Nomenclature is 15000. On August 6, 2012, ''Curiosity (rover), Curiosity'' (the Mars Science Laboratory rover) landed in "Yellowknife" ''Quad 51'' of Aeolis Palus, next to the mountain. NASA named the landing site Bradbury Landing on August 22, 2012. Aeolis Mons is a primary goal for scientific study. On June 5, 2013, NASA announced that ''Curiosity'' would begin an journey from the Glenelg, Mars, Glenelg area to the base of Aeolis Mons. On November 13, 2013, NASA announced that an entryway the rover would traverse on its way to Aeolis Mons was to be named "Murray Buttes", in honor of planetary scientist Bruce C. Murray (1931–2013). The trip was expected to take about a year and would include stops along the way to study the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sunset
Sunset, also known as sundown, is the daily disappearance of the Sun below the horizon due to Earth's rotation. As viewed from everywhere on Earth (except the North and South poles), the equinox Sun sets due west at the moment of both the spring and autumn equinoxes. As viewed from the Northern Hemisphere, the Sun sets to the northwest (or not at all) in the spring and summer, and to the southwest in the autumn and winter; these seasons are reversed for the Southern Hemisphere. The time of sunset is defined in astronomy as the moment when the upper limb of the Sun disappears below the horizon. Near the horizon, atmospheric refraction causes sunlight rays to be distorted to such an extent that geometrically the solar disk is already about one diameter below the horizon when a sunset is observed. Sunset is distinct from twilight, which is divided into three stages. The first one is ''civil twilight'', which begins once the Sun has disappeared below the horizon, and continues until ...

Extraterrestrial Skies
In astronomy, an extraterrestrial sky is a view of outer space from the surface of an astronomical body other than Earth. The only extraterrestrial sky that has been directly observed and photographed by astronauts is that of the Moon. The skies of Venus, Mars and Titan (moon), Titan have been observed by space probes designed to land on the surface and transmit images back to Earth. Characteristics of extraterrestrial sky appear to vary substantially due to a number of factors. An extraterrestrial atmosphere, if present, has a large bearing on visible characteristics. The atmosphere's density and chemical composition can contribute to differences in colour, Opacity (optics), opacity (including haze) and the presence of clouds. Astronomical objects may also be visible and can include natural satellites, planetary ring, rings, star systems and nebulas and other planetary system bodies.
