Glenelg, Mars
Glenelg (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 Canada is a country in North America. Its Provinces and territories of Canada, ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, making it the world's List of coun ..., 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timeline Of Mars Science Laboratory

As of , , ''Curiosity'' has been in Gale Crater on the Mars, planet Mars for Sol (day on Mars), sols ( days, total days; ') since landing on 6 August 2012. ''(See Timeline of Mars Science Laboratory#Current status, Current status.)'' Prelaunch (2004–2011) In April 2004, the United States National Aeronautics and Space Administration (NASA) called for scientific experiments and instruments proposals for the Mars Science Laboratory and rover mission. Launch was proposed for September 2009. By 14 December 2004, eight proposals were selected, including instruments from Russia and Spain. Testing of components also began in late 2004, including Aerojet's monopropellant engine with the ability to throttle from 15 to 100 percent thrust with a fixed propellant inlet pressure. By November 2008 most hardware and software development was complete, and testing cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rocks On Mars
Martian rocks and outcrops have been studied ''in-situ'' by various landers and rovers. While many of the rocks identified on the Martian surface are similar to each other, some have been considered scientifically important or otherwise notable and have been subjected to more extensive study or public interest. Names for Mars rocks are largely unofficial designations used for ease of discussion purposes, as the International Astronomical Union's official Martian naming system declares that objects smaller than are not to be given official names. Because of this, some less significant rocks seen in photos returned by Mars rovers have been named more than once, and others have even had their names changed later due to conflicts or even matters of opinion among researchers. Often rocks are named after the children or family members of astronauts or NASA employees. The rocks at the landing site of the '' Sojourner'' rover were given names of cartoon characters. Among them were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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'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 high density matter (mainly 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 ...

Aeolis Quadrangle
The Aeolis quadrangle is one of a series of list of quadrangles on Mars, 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 Aeolus, 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), ''Spirit'' rover landing site () in Gusev crater (January 4, 2004), and the Curiosity (rover), ''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 Guse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Balance
In photography and image processing, color balance is the global adjustment of the intensities of the colors (typically red, green, and blue primary colors). An important goal of this adjustment is to render specific colors – particularly neutral colors like white or grey – correctly. Hence, the general method is sometimes called gray balance, neutral balance, or white balance. Color balance changes the overall mixture of colors in an image and is used for color correction. Generalized versions of color balance are used to correct colors other than neutrals or to deliberately change them for effect. White balance is one of the most common kinds of balancing, and is when colors are adjusted to make a white object (such as a piece of paper or a wall) appear white and not a shade of any other colour. Image data acquired by sensors – either photographic film, film or electronic image sensors – must be transformed from the acquired values to new values that are appropriate ...

Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as '' spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bradbury Landing
Bradbury Landing is the August 6, 2012, landing site within Gale (crater), Gale crater on planet Mars of the Mars Science Laboratory (MSL) Curiosity rover, ''Curiosity'' rover. On August 22, 2012, on what would have been his 92nd birthday, NASA named the site for author Ray Bradbury, who had died on June 5, 2012. The coordinates of the landing site on Mars are: . The rover drove away from this specific landing location in the summer of 2012, but because of the nature of landing there is no actual lander there. The track prints and blast marks are slowly blowing away in the Martian wind, as recorded by Mars orbiters. Description Gale Crater was the MSL landing site in 2012. Within Gale Crater is a mountain, named Aeolis Mons ("Mount Sharp"), of layered rocks, rising about above the crater floor, that ''Curiosity'' will investigate. The landing site is a smooth region in "Yellowknife" ''Quad 51'' of Aeolis Palus inside the crater in front of the mountain. The target landing si ...
