Galle (Martian Crater)
Galle is a crater on Mars. It is located on the eastern rim of the huge impact basin Argyre Planitia in Argyre quadrangle. It is named after the German astronomer Johann Gottfried Galle. Galle is often known as the "happy face crater" because pareidolia causes a curved mountain range in the southern part of the crater and two smaller mountain clusters further north to appear to be a smiley face. The formation was first photographed by Viking Orbiter 1. A second "happy face crater", smaller than Galle and located at 45.1°S, 55.0°W in Nereidum Montes, was discovered by the Mars Reconnaissance Orbiter on January 28, 2008. Appearance in ''Watchmen'' As the smiley is a key motif in the comic book ''Watchmen'' by Alan Moore and Dave Gibbons, the crater was used as a story location after the coincidence was noted by Gibbons. According to Gibbons, the similarity "was almost too good to be true. I worried that if we put it in, people would never believe it." The crater also appear ...

Mars Global Surveyor
''Mars Global Surveyor'' (MGS) was an American robotic space probe developed by NASA's Jet Propulsion Laboratory and launched November 1996. MGS was a global mapping mission that examined the entire planet, from the ionosphere down through the atmosphere to the surface. As part of the larger Mars Exploration Program, Mars Global Surveyor performed atmospheric monitoring for sister orbiters during aerobraking, and helped Mars rovers and lander missions by identifying potential landing sites and relaying surface telemetry. It completed its primary mission in January 2001 and was in its third extended mission phase when, on 2 November 2006, the spacecraft failed to respond to messages and commands. A faint signal was detected three days later which indicated that it had gone into safe mode. Attempts to recontact the spacecraft and resolve the problem failed, and NASA officially ended the mission in January 2007. MGS remains in a stable near-polar circular orbit at about 450 km ...

Motif (visual Arts)
In art and iconography, a motif () is an element of an image. The term can be used both of figurative and narrative art, and ornament and geometrical art. A motif may be repeated in a pattern or design, often many times, or may just occur once in a work. A motif may be an element in the iconography of a particular subject or type of subject that is seen in other works, or may form the main subject, as the Master of Animals motif in ancient art typically does. The related motif of confronted animals is often seen alone, but may also be repeated, for example in Byzantine silk and other ancient textiles. Where the main subject of an artistic work such as a painting is a specific person, group, or moment in a narrative, that should be referred to as the "subject" of the work, not a motif, though the same thing may be a "motif" when part of another subject, or part of a work of decorative art such as a painting on a vase. Ornamental or decorative art can usually be analysed i ...

List Of Craters On Mars
__NOTOC__ This is a list of craters on Mars. Impact craters on Mars larger than exist by the hundreds of thousands, but only about one thousand of them have names. Names are assigned by the International Astronomical Union after petitioning by relevant scientists, and in general, only craters that have a significant research interest are given names. Martian craters are named after famous scientists and science fiction authors, or if less than in diameter, after towns on Earth. Craters cannot be named for living people, and names for small craters are rarely intended to commemorate a specific town. Latitude and longitude are given as planetographic coordinates with west longitude. Catalog of named craters The catalog is divided into three partial lists: * List of craters on Mars: A–G * List of craters on Mars: H–N * List of craters on Mars: O–Z Names are grouped into tables for each letter of the alphabet, containing the crater's name (linked if article exists), co ...

Galle (lunar Crater)
Galle is a small lunar impact crater on the Mare Frigoris, to the north-northeast of the prominent crater Aristoteles. The formation is nearly circular, with a sharp-edged rim and little appearance of erosion. There are slight outward bulges in the rim to the north and northeast, but otherwise the formation is relatively symmetrical. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Galle.

Cydonia (region Of Mars)
Cydonia (, ) is a region on the planet Mars that has attracted both scientific and popular interest. The name originally referred to the albedo feature (distinctively coloured area) that was visible from earthbound telescopes. The area borders the plains of Acidalia Planitia and the highlands of Arabia Terra. The region includes the named features Cydonia Mensae, an area of flat-topped mesa-like features; Cydonia Colles, a region of small hills or knobs; and Cydonia Labyrinthus, a complex of intersecting valleys. As with other albedo features on Mars, the name Cydonia was drawn from classical antiquity, in this case from ''Kydonia'' ( grc, Κυδωνία; lat, Cydonia), a historic ''polis'' (city state) on the island of Crete. Cydonia contains the "Face on Mars", located about halfway between the craters Arandas and Bamberg. Location Cydonia lies in the planet's northern hemisphere in a transitional zone between the heavily cratered regions to the south and relatively smooth ...

Dust Devil Tracks
Martian dust devils (dust devils on Mars) were first photographed by the Viking orbiters in the 1970s. In 1997, the Mars Pathfinder lander detected a dust devil passing over it. In the first image below, photographed by the Mars Global Surveyor, the long dark streak is formed by a moving swirling column of Martian atmosphere. The dust devil itself (the black spot) is climbing the crater wall. The streaks on the right are sand dunes on the crater floor. Martian dust devils can be up to fifty times as wide and ten times as high as terrestrial dust devils, and large ones may pose a threat to terrestrial technology sent to Mars. On 7 November 2016, five such dust devils ranging in heights of 0.5 to 1.9 km were imaged in a single observation by the Mars Orbiter Mission in the Martian southern hemisphere. Mission members monitoring the Spirit rover on Mars reported on March 12, 2005, that a lucky encounter with a dust devil had cleaned the solar panels of that robot. Power levels ...

Mars Reconnaissance Orbiter
''Mars Reconnaissance Orbiter'' (MRO) is a spacecraft designed to study the geology and climate of Mars, provide reconnaissance of future landing sites, and relay data from surface missions back to Earth. It was launched on August 12, 2005, and reached Mars on March 10, 2006. In November 2006, after five months of aerobraking, it entered its final science orbit and began its primary science phase. The cost to develop and operate MRO through the end of its prime mission in 2010 was . The spacecraft continues to operate at Mars, far beyond its intended design life. Due to its critical role as a high-speed data-relay for ground missions, NASA intends to continue the mission as long as possible, at least through the late 2020s. Pre-launch After the twin failures of the ''Mars Climate Orbiter'' and the Mars Polar Lander missions in 1999, NASA reorganized and replanned its Mars Exploration Program. In October 2000, NASA announced its reformulated Mars plans, which reduced the numb ...

Watchmen (film)
''Watchmen'' is a 2009 American superhero thriller film based on the 1986–1987 DC Comics limited series of the same name co-created and illustrated by Dave Gibbons with co-creator and author Alan Moore choosing to remain uncredited. Directed by Zack Snyder from a screenplay by David Hayter and Alex Tse, the film features Malin Åkerman, Billy Crudup, Matthew Goode, Carla Gugino, Jackie Earle Haley, Jeffrey Dean Morgan, and Patrick Wilson. A dark and dystopian deconstruction of the superhero genre, the film is set in an alternate history in the year 1985 at the height of the Cold War, as a group of mostly retired American superheroes investigates the murder of one of their own before uncovering an elaborate and deadly conspiracy, while their moral limitations are challenged by the complex nature of the circumstances. From October 1987 until October 2005, a live-action film adaptation of the ''Watchmen'' series became stranded in development hell. Producers Lawrence Gordon ...

Chicago Tribune
The ''Chicago Tribune'' is a daily newspaper based in Chicago, Illinois, United States, owned by Tribune Publishing. Founded in 1847, and formerly self-styled as the "World's Greatest Newspaper" (a slogan for which WGN radio and television are named), it remains the most-read daily newspaper in the Chicago metropolitan area and the Great Lakes region. It had the sixth-highest circulation for American newspapers in 2017. In the 1850s, under Joseph Medill, the ''Chicago Tribune'' became closely associated with the Illinois politician Abraham Lincoln, and the Republican Party's progressive wing. In the 20th century under Medill's grandson, Robert R. McCormick, it achieved a reputation as a crusading paper with a decidedly more American-conservative anti-New Deal outlook, and its writing reached other markets through family and corporate relationships at the ''New York Daily News'' and the ''Washington Times-Herald.'' The 1960s saw its corporate parent owner, Tribune Company, rea ...

Watchmen
''Watchmen'' is an American comic book Limited series (comics), maxiseries by the British creative team of writer Alan Moore, artist Dave Gibbons and colorist John Higgins (comics), John Higgins. It was published monthly by DC Comics in 1986 and 1987 before being collected in a single-volume edition in 1987. ''Watchmen'' originated from a story proposal Moore submitted to DC featuring superhero characters that the company had acquired from Charlton Comics. As Moore's proposed story would have left many of the characters unusable for future stories, managing editor Dick Giordano convinced Moore to create original characters instead. Moore used the story as a means to reflect contemporary anxieties, to deconstruct and satirize the superhero concept and political commentary. ''Watchmen'' depicts an alternate history in which superheroes emerged in the 1940s and 1960s and their presence changed history so that the United States won the Vietnam War and the Watergate scandal was neve ...
