HORTA (mining)
HORTA is an underground geographic positioning technology utilized in the mining industry and being considered for extraterrestrial space mining applications. The technology utilizes a gyroscope and an accelerometer, together called an inertial navigation system or INS, to aid in 3D-position determination. It was developed by Canadian mining company Inco in the late 1990s, based on an earlier technology that had been originally developed for the United States Armed Forces. It provides an automated solution to the problem of positioning and location in underground mines. The term is a backronym for the Horta, an alien species seen in the ''Star Trek'' episode "The Devil in the Dark"; the aliens were excellent miners. As Inco uses the term, HORTA stands for Honeywell Ore Retrieval and Tunneling Aid. A mining vehicle, "with a HORTA mounted, can survey much faster and more accurately than manual surveys. It takes the truck 120 minutes to survey a 1.6-km-long drift, recording 1,500 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geographic Positioning
Geopositioning is the process of determining or estimating the geographic position of an object or a person. Geopositioning yields a set of geographic coordinates (such as latitude and longitude) in a given map datum. Geographic positions may also be expressed indirectly, as a distance in linear referencing or as a bearing and range from a known landmark. In turn, positions can determine a meaningful location, such as a street address. Geoposition is sometimes referred to as ''geolocation'', and the process of geopositioning may also be described as ''geo-localization''. Specific instances include: * animal geotracking, the process of inferring the location of animals over time; * positioning system, the mechanisms for the determination of geographic positions in general; * internet geolocation, geolocating a device connected to the internet; * and mobile phone tracking. Geofencing ''Geofencing'' involves creating a virtual geographic boundary (a geofence), enabling software to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Backronym
A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The word is a portmanteau of ''back'' and ''acronym''. A normal acronym is a word derived from the initial letter(s) of the words of a phrase, such as ''radar'' from "radio detection and ranging". By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin". Many list of fictional espionage organizations, fictional espionage organizations are backronyms, such as SPECTRE (special executive for counterintelligence, terrorism, revenge and extortion) from the ''James Bond'' franchise. For example, the Amber Alert missing-child program was named after Amber Hagerman, a nine-year-old girl w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Space Show
''The Space Show'' is an Internet radio talk show about the development of outer space commerce and space tourism, and the issues impacting their development. It is also available archived online as a podcast. It airs 2 to 4 times per week, is hosted by Dr. David Livingston (born June 4, 1946), and features live guest interviews with call-in and email questions from listeners. According to Livingston, the show started in 2001 as ''Business without Boundaries'' on a small Arizona radio station, which added Internet audio streaming later. When the show moved to Seattle in 2002, it was renamed ''The Space Show'' and aired on, and streamed from, KKNW. ''The Space Show'' has now presented over 4,000 shows. Frequent guests on the show include: science journalist and historian Robert Zimmerman, physicist Dr. John Brandenberg, and engineering professor Dr. Haym Benaroya. Pete Worden, center director for NASA's Ames Research Center, described himself as a "reformed zealot" about spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teleoperation
Teleoperation (or remote operation) indicates operation of a system or machine at a distance. It is similar in meaning to the phrase "remote control" but is usually encountered in research, academia and technology. It is most commonly associated with robotics and mobile robots but can be applied to a whole range of circumstances in which a device or machine is operated by a person from a distance. Teleoperation can be considered a human-machine system. For example, ArduPilot provides a spectrum of autonomy ranging from manual control to full autopilot for autonomous vehicles. The term ''teleoperation'' is in use in research and technical communities as a standard term for referring to operation at a distance. This is as opposed to '' telepresence'' which is a less standard term and might refer to a whole range of existence or interaction that include a remote connotation. History The 19th century saw many inventors working on remotely operated weapons (torpedoes) incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave Survey
A cave survey is a map of all or part of a cave system, which may be produced to meet differing standards of accuracy depending on the cave conditions and equipment available underground. Cave surveying and cartography, i.e. the creation of an accurate, detailed map, is one of the most common technical activities undertaken within a cave and is a fundamental part of speleology. Surveys can be used to compare caves to each other by length, depth and volume, may reveal clues on speleogenesis, provide a spatial reference for other areas of scientific study and assist visitors with route-finding. Traditionally, cave surveys are produced in two-dimensional form due to the confines of print, but given the three-dimensional environment inside a cave, modern techniques using computer aided design are increasingly used to allow a more realistic representation of a cave system. History The first known plan of a cave dates from 1546, and was of a man-made cavern in tufa called the Stufe di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underground Mine Ventilation
Underground mine ventilation provides a flow of air to the underground workers of a mine with sufficient volume to dilute and remove dust and noxious gases (typically NOx, SO2, methane, CO2 and CO) and to regulate temperature. The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself. Regulations often require airflow to be distributed within mines to improve air quality. The largest component of the operating cost for mine ventilation is electricity to power the ventilation fans, which may account for one third of a typical underground mine's entire electrical power cost. Types of ventilation Flow-through ventilation is the main ventilation circuit for the mine. Air enters the mine from the surface via a shaft, ventilation raise or adit. The air is distributed through the mine via internal ventilation raises and ramps, and flows are controlled by regulators and permanently mounted ventilation fans. An auxiliar ...

Space Studies Institute
Space Studies Institute is a not-for-profit organization that was founded in 1977 by Princeton University Professor Gerard K. O'Neill. In 2009 SSI moved its operations from its long-term base in Princeton, New Jersey, to Mojave, California. SSI is involved in several initiatives, including a solar sail project that it is developing with Carnegie Mellon University and an effort to find asteroids that could be mined for valuable materials. The use of extraterrestrial resources in space settlement has received increasing attention in recent years. The Institute has sponsored research studies on several transport systems for the development of space. Their first program was in the development of prototype mass driver systems. They are also studying the use of an ''Orbital Transfer Vehicle'' as a component of space manufacturing. Other areas of research include a search for Earth-Sun Trojan asteroids, a design study of a ''Lunar Polar Probe'' to search for water and useful volati ...
