Bathurst Inlet (rock)
Bathurst Inlet is a rock on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons ("Mount Sharp"), in Gale crater on the planet Mars. The rock was encountered by the ''Curiosity'' rover on the way from Bradbury Landing to Glenelg Intrigue on September 30, 2012 and was named after Bathurst Inlet, a deep inlet located along the northern coast of the Canadian mainland. The "approximate" site coordinates are: . The NASA rover team had assessed the rock to be a suitable target for one of the first uses of ''Curiosity's'' contact instruments, the Mars Hand Lens Imager (MAHLI) and the Alpha particle X-ray spectrometer (APXS). The rock is dark gray and seems to contain grains or crystals, if any at all, that are finer than ''Curiosity's'' cameras can resolve: less than 80 μm in size.

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 ...

Timeline Of Mars Science Laboratory
The Mars Science Laboratory and its rover, ''Curiosity'', were launched from Earth on November 26, 2011. As of , , ''Curiosity'' has been on the planet Mars for sols ( total days; ') since landing on August 6, 2012. ''(See 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 December 14, 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 continued. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Rocks On Mars
This is an alphabetical list of named rocks (and meteorites) found on Mars, by mission. This list is a sampling of rocks viewed, and is not an exhaustive listing. A more complete listing may be found on the various NASA mission web sites. This listing does ''not'' include Martian meteorites found on Earth. 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. Often rocks are named after the children or family members of astronauts or NASA employees. The name ''Jazzy'', for example, was taken from a girl named Jazzy who grew up in Grand Junction, CO, USA. Her father worked for NASA and cont ... [...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, 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 ...

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, ...

Alpha Particle X-ray Spectrometer
:''APXS is also an abbreviation for APache eXtenSion tool, an extension for Apache web servers.'' An alpha particle X-ray spectrometer (APXS) is a spectrometer that analyses the chemical element composition of a sample from scattered alpha particles and fluorescent X-rays after a sample is irradiated with alpha particles and X-rays from radioactive sources. This method of analysing the elemental composition of a sample is most often used on space missions, which require low weight, small size, and minimal power consumption. Other methods (e.g. mass spectrometry) are faster, and do not require the use of radioactive materials, but require larger equipment with greater power requirements. A variation is the alpha proton X-ray spectrometer, such as on the Pathfinder mission, which also detects protons. Over the years several modified versions of this type of instrument such as APS (without X-ray spectrometer) or APXS have been flown: Surveyor 5-7, Mars Pathfinder, Mars 96, Mars ...

Northern Canada
Northern Canada, colloquially the North or the Territories, is the vast northernmost region of Canada variously defined by geography and politics. Politically, the term refers to the three Provinces_and_territories_of_Canada#Territories, territories of Canada: Yukon, Northwest Territories and Nunavut. This area covers about 48 per cent of Canada's total land area, but has less than 1 per cent of demographics of Canada, Canada's population. The terms "northern Canada" or "the North" may be used in contrast with ''the far north'', which may refer to the Canadian Arctic, the portion of Canada that lies north of the Arctic Circle, east of Alaska and west of Greenland. However, in many other uses the two areas are treated as a single unit. __TOC__ Definitions Subdivisions As a social rather than political region, the Canadian North is often subdivided into two distinct regions based on climate, the ''near north'' and the ''far north''. The different climates of these two regions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathurst Inlet
Bathurst Inlet, officially Kiluhiqtuq, is a deep inlet located along the northern coast of the Canadian mainland, at the east end of Coronation Gulf, into which the Burnside and Western rivers empty. The name, or its native equivalent ''Kingoak'' (''Qingaut'', ''nose mountain''), is also used to identify the community of Bathurst Inlet located on the shore. Melville Sound opens into the eastern side of the inlet at Cape Croker, west of the Hurd Islands. Plans for a deep-water port A consortium of seven mining companies sponsored environmental impact studies to construct a deep-water port in Bathurst Inlet. Their plans included building a road connecting the port to their mines. The port would serve vessels of up to 25,000 tonnes. A plan referred to the Nunavut Impact Review Board in May 2004 projected a capacity to moor vessels of up to 50,000 tonnes. In this earlier plan the Bathurst Inlet Road would be an ice road, like that from Yellowknife Yellowknife (; Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bradbury Landing
Bradbury Landing is the August 6, 2012, landing site within Gale crater on planet Mars of the Mars Science Laboratory (MSL) ''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 site location was an elliptical ...
