Iapygia Quadrangle
The Iapygia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Iapygia quadrangle is also referred to as MC-21 (Mars Chart-21). The Iapygia quadrangle covers the area from 270° to 315° west longitude and from 0° to 30° south latitude on Mars. Parts of the regions Tyrrhena Terra and Terra Sabaea are found in this quadrangle. The largest crater in this quadrangle is Huygens. Some interesting features in this quadrangle are dikes.Head, J. et al. 2006.

Quadrangle (geography)
A "quadrangle" is a topographic map produced by the United States Geological Survey (USGS) covering the United States. The maps are usually named after local physiographic features. The shorthand "quad" is also used, especially with the name of the map; for example, "the Ranger Creek, Texas quad". From approximately 1947-1992, the USGS produced the 7.5 minute series, with each map covering an area one-quarter of the older 15-minute quad series, which it replaced. A 7.5 minute quadrangle map covers an area of . Both map series were produced via photogrammetric analysis of aerial photography using stereoplotters supplemented by field surveys. These maps employ the 1927 North American Datum (NAD27); conversion or a change in settings is necessary when using a GPS which by default employ the WGS84 geodetic datum. Beginning in 2009, the USGS made available digital versions of 7.5 minute quadrangle maps based on GIS data that use the NAD83 datum, which is typically within one meter of ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saheki Crater
Saheki is a crater on Mars, located in the Iapygia quadrangle at 21.75° S and 286.97° W. It measures approximately 82 kilometers in diameter and was named after Tsuneo Saheki, a Japanese amateur astronomer (1916–1996). The naming was adopted by IAU's Working Group for Planetary System Nomenclature in 2006. The crater contains a number of alluvial fans, which are preserved in inverted relief.

Meteor Crater
Meteor Crater, or Barringer Crater, is a meteorite impact crater about east of Flagstaff and west of Winslow in the desert of northern Arizona, United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite, after the adjacent Cañon Diablo. Because the United States Board on Geographic Names recognizes names of natural features derived from the nearest post office, the feature acquired the name of "Meteor Crater" from the nearby post office named Meteor. Meteor Crater lies at an elevation of above sea level. It is about in diameter, some deep, and is surrounded by a rim that rises above the surrounding plains. The center of the crater is filled with of rubble lying above crater bedrock. One of the interesting features of the crater is its squared-off outline, believed to be caused by existing regional jointing (cracks) in the strata at the impact site. Despite historic attempts to make the crater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winslow, Arizona
Winslow ( nv, ) is a city in Navajo County, Arizona, United States. According to the 2010 census, the population of the city is 9,655. It is approximately southeast of Flagstaff, west of Albuquerque, New Mexico, and southeast of Las Vegas. History Winslow was named for either Edward F. Winslow, president of St. Louis and San Francisco Rail Road, which owned half of the old Atlantic and Pacific Railroad, or Tom Winslow, a prospector who lived in the area. The last Harvey House (La Posada Hotel), designed by Mary Colter, opened in 1930. The hotel closed in 1957 and was used by the Santa Fe Railway for offices. The railroad abandoned La Posada in 1994 and announced plans to tear it down. It was bought and restored by Allan Affeldt and it serves as a hotel. U.S. Route 66 was originally routed through the city. A contract to build Interstate 40 as a bypass north of Winslow was awarded at the end of 1977. I-40 replaced U.S. Route 66 in Arizona in its entirety. Winslow ach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Schaeberle Crater
John Martin Schaeberle (January 10, 1853 – September 17, 1924) was a German-American astronomer. Biography He was born Johann Martin Schäberle in Württemberg, Germany, but in 1854 immigrated as an infant to the United States. Most sources refer to him as John M. Schaeberle, but his family and friends called him Martin. He attended public schools, and then became an apprentice in a machine shop. During his apprenticeship, he became interested in astronomy, and decided to finish high school. He then became a student of James Craig Watson at the University of Michigan. He graduated from the University of Michigan in 1876 as a civil engineer, but devoted himself to astronomy. He taught astronomy at the University of Michigan from 1876 to 1888. He maintained his own private observatory and discovered three comets. In 1888 he became one of the inaugural astronomers at Lick Observatory. He had charge of the expedition to witness the solar eclipse at Cayenne in 1889, and of those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terby Crater
Terby is a crater on the northern edge of Hellas Planitia, Mars. It is in the Iapygia quadrangle. The crater is centered at 28°S, 73°E with an elevation of . It is named after François J. Terby. It is the site of an ancient lakebed and has clay deposits. Using data from Mars Global Surveyor, Mars Odyssey, Mars Express, and Mars Reconnaissance Orbiter missions researchers believe Terby's layers were formed from sediments settling under water. Crater counts show this happened during the Noachian period. It used to be thought that Terby Crater contained a large delta. However, newer observations have led researchers to think of the layered sequence as part of a group of layers that may have extended all the across Hellas. There is no valley large enough at the northern rim of Terby to have carried the large amount of sediments necessary to produce the layers. Other details in the layers argue against Terby's containing a delta. Fan deposits are some of the thickest on Mars. Hydrat ...

HiWish Program
HiWish is a program created by NASA so that anyone can suggest a place for the HiRISE camera on the Mars Reconnaissance Orbiter to photograph. It was started in January 2010. In the first few months of the program 3000 people signed up to use HiRISE. The first images were released in April 2010. Over 12,000 suggestions were made by the public; suggestions were made for targets in each of the 30 quadrangles of Mars. Selected images released were used for three talks at the 16th Annual International Mars Society Convention. Below are some of the over 4,224 images that have been released from the HiWish program as of March 2016. Glacial features Some landscapes look just like glaciers moving out of mountain valleys on Earth. Some have a hollowed-out appearance, looking like a glacier after almost all the ice has disappeared. What is left are the moraines—the dirt and debris carried by the glacier. The center is hollowed out because the ice is mostly gone. These supposed alp ...

HiRISE
High Resolution Imaging Science Experiment is a camera on board the ''Mars Reconnaissance Orbiter'' which has been orbiting and studying Mars since 2006. The 65 kg (143 lb), US$40 million instrument was built under the direction of the University of Arizona's Lunar and Planetary Laboratory by Ball Aerospace & Technologies Corp. It consists of a 0.5m (19.7 in) aperture reflecting telescope, the largest so far of any deep space mission, which allows it to take pictures of Mars with resolutions of 0.3m/pixel (1ft/pixel), resolving objects below a meter across. HiRISE has imaged Mars exploration rovers on the surface, including the ''Opportunity'' rover and the ongoing ''Curiosity'' mission. History In the late 1980s, of Ball Aerospace & Technologies began planning the kind of high-resolution imaging needed to support sample return and surface exploration of Mars. In early 2001 he teamed up with Alfred McEwen of the University of Arizona to propose such a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
THEMIS
In Greek mythology and Ancient Greek religion, religion, Themis (; grc, Θέμις, Themis, justice, law, custom) is one of the twelve Titans, Titan children of Gaia and Uranus (mythology), Uranus, and the second wife of Zeus. She is the goddess and personification of justice, divine order, fairness, law, and custom, and her symbols include the Scales of Justice (symbol), Scales of Justice. She is also associated with oracles and prophecies, including the Pythia, Oracle of Delphi. Name ''Themis'' means "divine law" rather than human ordinance, literally "that which is put in place", from the Greek verb ''títhēmi'' (wikt:τίθημι, τίθημι), meaning "to put." To the ancient Greeks she was originally the organizer of the "communal affairs of humans, particularly assemblies." Moses Finley remarked of ''themis'', as the word was used by Homer in the 8th century BCE, to evoke the social order of the 10th- and 9th-century Greek Dark Ages: Finley adds, "There was ''them ...
