Haughton Impact Crater
Haughton impact crater is located on Devon Island, Nunavut in far Northern Canada. It is about in diameter and was formed 31-32 million years ago during the Early Oligocene. The impacting object is estimated to have been approximately in diameter. Devon Island itself is composed of Paleozoic shale and siltstone overlying gneissic bedrock. When the crater formed, the shale and siltstone were peeled back to expose the basement; material from as deep as has been identified. Description At 75° north latitude, it is one of the highest-latitude impact craters known. The temperature is below the freezing point of water for much of the year, and the limited vegetation is slow-growing, leading to very little weathering. For this reason Haughton retains many geological features that lower-latitude craters lose to erosion. Because Haughton's geology and climatology are as close to Mars-like as can be had on Earth, Haughton and its environs have been dubbed by scientists working ...

Devon Island
Devon Island ( iu, ᑕᓪᓗᕈᑎᑦ, ) is an island in Canada and the largest uninhabited island (no permanent residents) in the world. It is located in Baffin Bay, Qikiqtaaluk Region, Nunavut, Canada. It is one of the largest members of the Arctic Archipelago, the second-largest of the Queen Elizabeth Islands, Canada's sixth-largest island, and the 27th-largest island in the world. It has an area of (slightly smaller than Croatia). The bedrock is Precambrian gneiss and Paleozoic siltstones and shales. The highest point is the Devon Ice Cap at which is part of the Arctic Cordillera. Devon Island contains several small mountain ranges, such as the Treuter Mountains, Haddington Range and the Cunningham Mountains. The notable similarity of its surface to that of Mars has attracted interest from scientists. History and settlement Robert Bylot and William Baffin were the first Europeans to sight Devon Island in 1616. William Edward Parry charted its south coast in 1819–20, ...

Breccia
Breccia () is a rock composed of large angular broken fragments of minerals or rocks cemented together by a fine-grained matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, tectonic breccia, igneous breccia, impact breccia, and hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down. These indicate that the gravel was deposited very close to its source area, since otherwise th ...

Bartonian Stage
The Bartonian is, in the ICS's geologic time scale, a stage or age in the middle Eocene Epoch or Series. The Bartonian Age spans the time between . It is preceded by the Lutetian and is followed by the Priabonian Age. Stratigraphic definition The Bartonian Stage was introduced by Swiss stratigrapher Karl Mayer-Eymar in 1857. The name derives from the coastal village Barton-on-Sea (part of New Milton) in southern England. The Barton Group, a lithostratigraphic unit from the south English Hampshire Basin, is of Bartonian age. The distinction between group and stage was made in the second part of the 20th century, when stratigraphers saw the need to distinguish between litho- and chronostratigraphy. The base of the Bartonian is at the first appearance of the calcareous nanoplankton species ''Reticulofenestra reticulata''. In 2009, an official reference profile (GSSP) for the base of the Bartonian had not yet been established. The top of the Bartonian Stage (the base of the Pria ...

Eocene Impact Craters
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ...

Flashline Mars Arctic Research Station
The Flashline Mars Arctic Research Station (FMARS) is the first of two simulated Mars habitats (or Mars Analog Research Stations) located on Devon Island, Nunavut, Canada, which is owned and operated by the Mars Society. The station is a member of the EU-INTERACT, circumarctic network of currently 89 terrestrial field bases located in northern Europe, Russia, US, Canada, Greenland, Iceland, the Faroe Islands, and Scotland as well as stations in northern alpine areas. Background The station is located on Devon Island, a Mars analog environment and polar desert, approximately north east of the hamlet of Resolute in Nunavut, Canada. The station is situated on Haynes Ridge, overlooking the Haughton impact crater, a diameter crater formed approximately 39 million years ago (late Eocene). The location is approximately from the Geographic North Pole and approximately from the Magnetic North Pole. FMARS is the first research station of its kind to be built, completed in the ...

Haughton–Mars Project
The Haughton–Mars Project (HMP) is an international interdisciplinary field research project being carried out near the Haughton impact crater on Canada's northern Devon Island. Human-centered computing (HCC) studies are aimed at determining how human explorers might live and work on other planetary objects, in particular on Mars. Conducted jointly by SETI and the Mars Institute, the project's goal is to utilize the Mars-like features of Devon Island and the impact crater to develop and test new technologies and field operating procedures, and to study the human dynamics which result from extended contact in close quarters. This knowledge will be used in planning missions by both humans and robots to other terrestrial bodies. The HMP came about as a postdoctoral research proposal by Pascal Lee, then a Cornell University graduate student. The proposal was approved by the National Research Council and NASA Ames Research Center in 1996. By 2000, the science and exploration research ...

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury (planet), Mercury. In the English language, Mars is named for the Mars (mythology), Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos (moon), Phobos and Deimos (moon), Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and List of tallest mountains in the Solar System, highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The North Polar Basin (Mars), Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a la ...
