Phoebe Regio
Phoebe Regio is a regio on the planet Venus. It lies to the southeast of Asteria Regio. It is in diameter and is the principal feature of the V41 quadrangle, to which it gave its name. Four Soviet landers, Venera 11, Venera 12, Venera 13 and Venera 14 Venera 14 (russian: Венера-14 meaning Venus 14) was a probe in the Soviet Venera program for the exploration of Venus. Venera 14 was identical to the Venera 13 spacecraft, built to take advantage of the 1981 Venus launch opportunity.

Magellan (spacecraft)
The ''Magellan'' spacecraft was a robotic space probe launched by NASA of the United States, on May 4, 1989, to map the surface of Venus by using synthetic-aperture radar and to measure the planetary gravitational field. The ''Magellan'' probe was the first interplanetary mission to be launched from the Space Shuttle, the first one to use the Inertial Upper Stage booster, and the first spacecraft to test aerobraking as a method for circularizing its orbit. ''Magellan'' was the fifth successful NASA mission to Venus, and it ended an eleven-year gap in U.S. interplanetary probe launches. History Beginning in the late 1970s, scientists advocated for a radar mapping mission to Venus. They first sought to construct a spacecraft named the ''Venus Orbiting Imaging Radar'' (VOIR), but it became clear that the mission would be beyond the budget constraints during the ensuing years. The VOIR mission was canceled in 1982. A simplified radar mission proposal was recommended by the Solar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteria (Titaness)
In Greek mythology, Asteria or Asterie (; grc, Ἀστερία or Ἀστερίη, Astería/Asteríē, of the stars, starry one) is a daughter of the Titans Coeus (Polus) and Phoebe and the sister of Leto. According to Hesiod, by the Titan Perses she had a single child, a daughter named Hecate, the goddess of witchcraft.Hesiod, ''Theogony'409–11 Apollodorus1.2.4/ref> Other authors made Asteria the mother of the fourth Heracles and HecateAccording to Musaeus as cited by a scholiast on Apollonius Rhodius's ''Argonautica'3.467/ref> by Zeus. Asteria is notable for her pursuit by the amorous god Zeus, who desired her. In order to escape him and his advances, she transformed herself into a bird and then a wandering island. When her sister Leto, impregnated by Zeus, went into labour, Asteria was the only place on earth willing to receive her, defying Hera's orders that forbade Leto any shelter. After Apollo and Artemis were born on her, the island received the name of Delos, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planet
A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk. Planets grow in this disk by the gradual accumulation of material driven by gravity, a process called accretion. The Solar System has at least eight planets: the terrestrial planets Mercury, Venus, Earth and Mars, and the giant planets Jupiter, Saturn, Uranus and Neptune. These planets each rotate around an axis tilted with respect to its orbital pole. All of them possess an atmosphere, although that of Mercury is tenuous, and some share such features as ice caps, seasons, volcanism, hurricanes, tectonics, and even hydrology. Apart from Venus and Mars, the Solar System planets generate magnetic fields, and all except Venus and Mercury have natural satellites. The giant planets bear plan ...

Venus
Venus is the second planet from the Sun. It is sometimes called Earth's "sister" or "twin" planet as it is almost as large and has a similar composition. As an interior planet to Earth, Venus (like Mercury) appears in Earth's sky never far from the Sun, either as morning star or evening star. Aside from the Sun and Moon, Venus is the brightest natural object in Earth's sky, capable of casting visible shadows on Earth at dark conditions and being visible to the naked eye in broad daylight. Venus is the second largest terrestrial object of the Solar System. It has a surface gravity slightly lower than on Earth and has a very weak induced magnetosphere. The atmosphere of Venus, mainly consists of carbon dioxide, and is the densest and hottest of the four terrestrial planets at the surface. With an atmospheric pressure at the planet's surface of about 92 times the sea level pressure of Earth and a mean temperature of , the carbon dioxide gas at Venus's surface is in the ...

Hecate Chasma
Hecate or Hekate, , ; grc-dor, Ἑκάτᾱ, Hekátā, ; la, Hecatē or . is a goddess in ancient Greek religion and mythology, most often shown holding a pair of torches, a key, snakes, or accompanied by dogs, and in later periods depicted as three-formed or triple-bodied. She is variously associated with crossroads, entrance-ways, night, light, magic, witchcraft, the Moon, knowledge of herbs and poisonous plants, graves, ghosts, necromancy, and sorcery.Seyffert, s.vHecate/ref>d'Este, Sorita & Rankine, David, Hekate Liminal Rites, Avalonia, 2009. Her earliest appearance in literature was in Hesiod's ''Theogony'' in the 8th century BCE as a goddess of great honour with domains in sky, earth, and sea. Her place of origin is debated by scholars, but she had popular followings amongst the witches of Thessaly and an important sanctuary among the Carian Greeks of Asia Minor in Lagina. Her oldest known representation was found in Selinunte, in Sicily. Hecate was one of several d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency. The USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS also has major offices near Lakewood, Colorado, at the Denver Federal Center, and Menlo Park, California. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on the occasion of its hundredt ...

Guinevere Planitia Quadrangle
Guinevere ( ; cy, Gwenhwyfar ; br, Gwenivar, kw, Gwynnever), also often written in Modern English as Guenevere or Guenever, was, according to Arthurian legend, an Early Middle Ages, early-medieval queen of Great Britain and the wife of King Arthur. First mentioned in popular literature in the early 12th century, nearly 700 years after the purported times of Arthur, Guinevere has since been portrayed as everything from a villainous and opportunistic traitor to a fatally flawed but noble and virtuous lady. Many records of the legend also feature the variably recounted story of her abduction and rescue as a major part of the tale. The earliest datable appearance of Guinevere is in Geoffrey of Monmouth's pseudo-historical British chronicle ''Historia Regum Britanniae'', in which she is seduced by Mordred during his ill-fated rebellion against Arthur. In a later medieval Arthurian Chivalric romance, romance tradition from France, a prominent story arc is the queen's tragic love af ...
