Doom Mons
Doom Mons is the name of a mountain mountain range, range and its eponymous peak on Titan (moon), Titan, the largest moon of Saturn. A putative cryovolcano, it is the largest mountain range on Titan by volume. It was discovered by the Cassini–Huygens, ''Cassini–Huygens'' probe in 2005 and officially named in 2012. Naming Doom Mons is named after Mount Doom, a volcano that appears in J. R. R. Tolkien's fictional world of Middle-earth, most prominently in ''The Lord of the Rings''. The name follows Astronomical naming conventions, a convention by the International Astronomical Union, IAU Working Group for Planetary System Nomenclature that Titanean mountains are named after mountains in Tolkien's works. Other examples of Titanean mountains or mountain ranges List of geological features on Titan#Montes, named after Tolkien's works include Erebor Mons, the Irensaga Montes, Mindolluin Montes, Misty Montes, Mithrim Montes, and Taniquetil Montes.

Sotra Patera
Sotra Patera (named after Sotra island in Norway) is a prominent depression on Titan (moon), Titan, the largest moons of Saturn, moon of Saturn. It was formerly known as Sotra Facula; the current name was approved on 19 December 2012. It is a possible cryovolcanic caldera across and deep, and is immediately to the east of the largest putative cryovolcanic mountain on Titan, the high Doom Mons. Sotra Patera is the deepest known pit on Titan. The ice volcano or cryovolcano Doom Mons forms a roughly circular mountain measuring about across. It has two peaks standing about and high with multiple craters, with Sotra Patera at being the deepest. Finger-like flows are visible on the flanks of the mountain, measuring perhaps thick.Cassini Spots Potential Ice Volcano on Saturn Moon [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irensaga Montes
The Irensaga Montes is a range of mountains on Titan, the largest moon of the planet Saturn. The range is located near Titan's equator, between 5–6° south and 210–214° east. It is located within the Adiri region, just west of the landing site of the Huygens probe. The Irensaga Montes is named after Irensaga, one of the White Mountains in J. R. R. Tolkien's fictional world of Middle-earth Middle-earth is the Setting (narrative), setting of much of the English writer J. R. R. Tolkien's fantasy. The term is equivalent to the ''Midgard, Miðgarðr'' of Norse mythology and ''Middangeard'' in Old English works, including ''Beowulf'' .... The name follows a convention that Titanean mountains are after mountains in Tolkien's work. It was formally announced on November 13, 2012.Jennifer Blue"Eight New Names for Titan Surface Features".

Ethane
Ethane ( , ) is a naturally occurring Organic compound, organic chemical compound with chemical formula . At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is List of purification methods in chemistry, isolated on an industrial scale from natural gas and as a petrochemical by-product of oil refinery, petroleum refining. Its chief use is as feedstock for ethylene production. The ethyl group is formally, although rarely practically, derived from ethane. History Ethane was first synthesised in 1834 by Michael Faraday, applying electrolysis of a potassium acetate solution. He mistook the hydrocarbon product of this reaction for methane and did not investigate it further. The process is now called Kolbe electrolysis: : acetate, CH3COO− → CH3• + carbon dioxide, CO2 + electron, e− : CH3• + •CH3 → C2H6 During the period 1847–1849, in an effort to vindicate the radical theory of organic chemistry, Hermann Kolbe ...

Methane
Methane ( , ) is a chemical compound with the chemical formula (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it is difficult because it is a gas at standard temperature and pressure. In the Earth's atmosphere methane is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. Methane is an Organic chemistry, organic Organic compound, compound, and among the simplest of organic compounds. Methane is also a hydrocarbon. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the Atmosphere of Earth, atmosphere, it is known as atmospheric methane. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Of Titan
The climate of Titan (moon), Titan, the largest moon of Saturn, is similar in many respects to that of Earth, despite having a far lower surface temperature. Its thick Atmosphere of Titan, atmosphere, methane rain, and possible cryovolcanism create an analogue, though with different materials, to the climatic changes undergone by Earth during the far shorter year of Earth. Temperature Titan receives just about 1% of the amount of sunlight Earth does. The average surface temperature is about 90.6 K (-182.55 °C, or -296.59 °F). At this temperature water ice has an extremely low vapor pressure, so the atmosphere is nearly free of water vapor. However the methane in the atmosphere causes a substantial greenhouse effect which keeps the surface of Titan at a much higher temperature than what would otherwise be the thermal equilibrium. Haze in Titan's atmosphere contributes to an anti-greenhouse effect by reflecting sunlight back into space, making its surface signifi ...

Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a Federally funded research and development centers, federally funded research and development center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States. Founded in 1936 by California Institute of Technology (Caltech) researchers, the laboratory is now owned and sponsored by NASA and administered and managed by Caltech. The primary function of the laboratory is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating the NASA Deep Space Network (DSN). Among the major active projects at the laboratory, some are the Mars 2020 mission, which includes the ''Perseverance (rover), Perseverance'' rover; the Mars Science Laboratory mission, including the ''Curiosity (rover), Curiosity'' rover; the ''Mars Reconnaissance Orbiter''; the ''Juno (spacecraft), Juno'' spacecraft orbiting Jupiter; the ''Soil Moisture Active P ...

Dunes
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes, with little or no vegetation, are called '' ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...
