Feuillée (crater)
Feuillée is a small lunar impact crater in the eastern part of the Mare Imbrium. It was named after French natural scientist Louis Feuillée. It lies less than a half crater diameter to the northwest of Beer, and the two formations form a nearly matched pair. To the west is the small but prominent crater Timocharis. Like Beer, Feuillée is a circular, bowl-shaped formation with a small interior floor at the midpoint of the sloping inner walls. This sharp-edged crater is not notably worn or eroded, and lacks any distinguishing features. It does, however, lie across a wrinkle ridge in the surface of the lunar mare The lunar maria ( ; mare ) are large, dark, basaltic plains on Earth's Moon, formed by lava flowing into ancient impact basins. They are less reflective than the "highlands" as a result of their iron-rich composition, and hence appear dark to ..., a feature that is best observed under oblique lighting conditions when the crater is near the terminator.

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the Apollo program and the fourth Moon landing. It was the first List of Apollo missions#Alphabetical mission types, J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Apollo Commander, Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley–Apennine#Rima Hadley, Hadley Rille and explored the local area using the rover, allowing them to travel further from the Apollo Lunar Module, Lunar Module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moon, operating the sensors in the scie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beer (lunar Crater)
Beer is a relatively small lunar impact crater located on the Mare Imbrium, to the east of the crater Timocharis. It was named after German astronomer Wilhelm W. Beer. Just to the northwest is the matching twin Feuillée. Beer is a circular, cup-shaped crater with a sharp-edged rim that has not been significantly eroded. The interior has a higher albedo than the surrounding lunar mare, which is usually an indication of a relatively young crater. A string of craters arc away from the rim to the southeast, which then grade into a straight rille, and were once known as Fossa Archimedes or Archimedes Rille, but now are officially unnamed. The mare to the east has a higher albedo than the surrounding surface, and this lighter-hued surface reaches to the base of the Montes Archimedes. To the southeast of Beer is a lunar dome A lunar dome is a type of shield volcano that is found on the surface of the Earth's Moon. They are typically formed by highly viscous, possibly silica-ri ...

Louis Feuillée
Louis Éconches Feuillée (sometimes spelled Feuillet; 1660 – 18 April 1732) was a French member of the Order of the Minims, explorer, astronomer, geographer and botanist. Biography Feuillée was born in Mane in Provence in 1660. He was educated at the Minim convent of Mane. He was taught astronomy and cartography by Jean Mathieu de Chazelles, and Charles Plumier, who had described some 6,000 species of plants during a voyage to the Caribbean, taught him botany. He attracted the attention of members of the Academy of Sciences and in 1699 was sent by order of the king on a voyage to the Levant with Giovanni Domenico Cassini to determine the geographical positions of a number of seaports and other cities. The success of the undertaking led him to make a similar journey to the Antilles in 1703. He left Marseille on 5 February 1703 and arrived at Martinique on 11 April. In September of the following year he began a cruise along the northern coast of South America, making obse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Craters
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. History The word ''crater'' was adopted from the Greek language, Greek word for "vessel" (, a Greek vessel used to mix wine and water). Galileo built his refracting telescope, first telescope in late 1609, and turned it to the Moon for the first time on November 30, 1609. He discovered that, contrary to general opinion at that time, the Moon was not a perfect sphere, but had both mountains and cup-like depressions. These were named craters by Johann Hieronymus Schröter (1791), extending its previous use with volcanoes. Robert Hooke in ''Micrographia'' (1665) proposed two hypotheses for lunar crater formation: one, that the craters were caused by projectile bombardment from space, the other, that they were the products of subterranean lunar volcanism. ...

Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids. On other planet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mare Imbrium
Mare Imbrium (Latin ''imbrium'', the "Sea of Showers" or "Sea of Rains") is a vast lunar mare, lava plain within the Imbrium Basin on the Moon and is one of the larger craters in the Solar System. The Imbrium Basin formed from the collision of a Protoplanet, proto-planet during the Late Heavy Bombardment. Basaltic lava later flooded the giant Impact crater, crater to form the flat volcanic plain seen today. The basin's age has been estimated using Uranium–lead dating, uranium–lead dating methods to approximately 3.9 billion years ago, and the diameter of the impactor has been estimated to be 250 ± 25 km. The Moon's maria (plural of Lunar mare, mare) have fewer features than other areas of the Moon because molten lava pooled in the craters and formed a relatively smooth surface. Mare Imbrium is not as flat as it would have originally been when it first formed as a result of later events that have altered its surface. Origin Mare Imbrium formed when a proto-planet ...

Timocharis (crater)
Timocharis is a prominent Lunar craters, lunar impact crater located on the Mare Imbrium. It was named after ancient Greek astronomer Timocharis. The closest crater of comparable dimensions is Lambert (lunar crater), Lambert to the west. The smaller craters Feuillée (crater), Feuillée and Beer (lunar crater), Beer lie to the east of Timocharis. The rim of Timocharis has a somewhat polygonal outline, with an outer wikt:rampart, rampart that extends over 20 kilometers in all directions. The interior wall is slumped and sharply terraced. The center of the floor is occupied by a craterlet that lies on a slight rise. This impact has almost completely removed the original central peak. The crater may have a minor ray system that extends for over . The crater is likely to have been formed in the Eratosthenian, between 3.2 and 1.1 Billion years ago, as it lacks a prominent ray system, but has not been significantly eroded by impacts.

Wrinkle Ridge
A wrinkle ridge is a type of feature commonly found on lunar maria, or basalt plains. These features are low, sinuous ridges formed on the mare surface that can extend for up to several hundred kilometers. Wrinkle ridges are tectonic features created after the lava cooled and solidified. They frequently outline ring structures buried within the mare, follow circular patterns outlining the mare, or intersect protruding peaks. They are sometimes called ''veins'' due to their resemblance to the veins that protrude from beneath the skin. Wrinkle ridges are named with the Latin designation ''dorsum'' (plural ''dorsa''). The standard IAU nomenclature uses the names of people (generally scientists) to identify wrinkle ridges on the Moon. For example, the Dorsa Burnet are named for Thomas Burnet, and the Dorsum Owen is named after George Owen of Henllys. Wrinkle ridges can also be found on Mars, for example in Chryse Planitia, on several of the asteroids that have been visited ...

Lunar Mare
The lunar maria ( ; mare ) are large, dark, basaltic plains on Earth's Moon, formed by lava flowing into ancient impact basins. They are less reflective than the "highlands" as a result of their iron-rich composition, and hence appear dark to the naked eye. The maria cover about 16% of the lunar surface, mostly on the side visible from Earth. The few maria on the far side are much smaller, residing mostly in very large craters. The traditional nomenclature for the Moon also includes one (ocean), as well as features with the names ('lake'), ('marsh'), and ('bay'). The last three are smaller than maria, but have the same nature and characteristics. The names of maria refer to sea features ( Mare Humorum, Mare Imbrium, Mare Insularum, Mare Nubium, Mare Spumans, Mare Undarum, Mare Vaporum, Oceanus Procellarum, Mare Frigoris), sea attributes ( Mare Australe, Mare Orientale, Mare Cognitum, Mare Marginis), or states of mind ( Mare Crisium, Mare Ingenii, Mare Serenita ...
