Ariadne Crater
Ariadne (; grc-gre, Ἀριάδνη; la, Ariadne) was a Cretan princess in Greek mythology. She was mostly associated with mazes and labyrinths because of her involvement in the myths of the Minotaur and Theseus. She is best known for having helped Theseus escape the Minotaur but being abandoned by him on the island of Naxos; subsequently, she became the wife of Dionysus. (There are many other versions of her myth.) The ancient Roman author Hyginus identified Ariadne as the Roman Libera/ Proserpina at approximately the same time as Libera was officially identified with Proserpina in 205 BC, these two names becoming synonymous for the same goddess. Hyginus equated Libera/Proserpina with Ariadne as bride to Liber whose Greek equivalent was Dionysus, the husband of Ariadne. Etymology Greek lexicographers in the Hellenistic period claimed that ''Ariadne'' is derived from the ancient Cretan dialectical elements ''ari'' (ἀρι-) "most" (which is an intensive prefix) ...

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 S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Craters On Venus
This is a list of craters on Venus, named by the International Astronomical Union's (IAU) Working Group for Planetary System Nomenclature. All craters on Venus are named after famous women or female first names. ''(For features on Venus other than craters see, list of montes on Venus and List of coronae on Venus.)'' As of 2017, there are 900 named craters on Venus, fewer than the lunar and Martian craters but more than on Mercury. Other, non-planetary bodies with numerous named craters include Callisto (141), Ganymede ( 131), Rhea (128), Vesta (90), Ceres (90), Dione (73), Iapetus (58), Enceladus (53), Tethys (50) and Europa ( 41).

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 t ...

Prime Meridian
A prime meridian is an arbitrary meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, like the Earth, into two hemispheres: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system). For Earth's prime meridian, various conventions have been used or advocated in different regions throughout history. The Earth's current international standard prime meridian is the IERS Reference Meridian. It is derived, but differs slightly, from the Greenwich Meridian, the previous standard. A prime meridian for a planetary body not tidally locked (or at least not in synchronous rotation) is entirely arbitrary, unlike an equator, which is determined by the axis of rotation. However, for celestial objects that are tidally locked (more specifically, synchronous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eve (crater)
Eve (; ; ar, حَوَّاء, Ḥawwāʾ; el, Εὕα, Heúa; la, Eva, Heva; Syriac: romanized: ) is a figure in the Book of Genesis in the Hebrew Bible. According to the origin story, "Creation myths are symbolic stories describing how the universe and its inhabitants came to be. Creation myths develop through oral traditions and therefore typically have multiple versions." of the Abrahamic religions, she was the first woman, yet some debate within Judaism has also given that position to Lilith. Eve is known also as Adam's wife. According to the second chapter of Genesis, Eve was created by God (Yahweh) by taking her from the rib of Adam, to be Adam's companion. Adam is charged with guarding and keeping the garden before her creation; she is not present when God commands Adam not to eat the forbidden fruit – although it is clear that she was aware of the command. She decides to eat the forbidden fruit from the tree of the knowledge of good and evil after she hears the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
