Mons Agnes
Mons Agnes is a hill ( "mountain") on the Moon, in Lacus Felicitatis, inside the crater-like feature Ina, at . It has a maximal width of approximately 650 m (the smallest of all named lunar mountains as of 2014). Its height is more difficult to determine; from Apollo 15 images it was determined as about 30 m, but a newer map, based on LRO photos, gives about 10 m. Mons Agnes (and the entire Ina crater) was discovered on the photos made by Apollo 15 from lunar orbit in 1971. In 1974 NASA published a topophotomap where its name first appeared: it received Greek feminine name Agnes. In 1979 this name (with a term ''Mons'' – "mountain") was adopted by the International Astronomical Union The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreac ....

Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program. The probe has made a 3-D map of the Moon's surface at 100-meter resolution and 98.2% coverage (excluding polar areas in deep shadow), including 0.5-meter resolution images of Apollo landing sites. The first images f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Mountains On The Moon
Mountains on the Moon have heights defined relative to various vertical datums. In the 1960s, the U.S. Army Mapping Service used elevation relative to 1,737,988 meters from the center of the Moon. In the 1970s, the U.S. Defense Mapping Agency used 1,730,000 meters. The '' Clementine'' topographic data published in the 1990s uses 1,737,400 meters. This table is not comprehensive, and does not list the highest places on the Moon. ''Clementine'' data show a range of about 18,100 meters from lowest to highest point on the Moon. The highest point, located on the far side of the Moon, is approximately 6,500 meters higher than Mons Huygens (usually listed as the tallest mountain).

Agnes (name)
Agnes is a female given name derived from the Greek , meaning 'pure' or 'holy'. The name passed to Italian language, Italian as Agnese, to French language, French as Agnès, to Portuguese language, Portuguese as Inês, and to Spanish language, Spanish as Inés. It is also written as Agness. The name is descended from the Proto-Indo-European ''wikt:Reconstruction:Proto-Indo-European/h₁yaǵ-, *h₁yaǵ-'', meaning 'to sacrifice; to worship,' from which is also the Vedic term ''Yajna, yajña''. It is mostly used in Greece and countries that speak Germanic languages. It was the name of a popular Christian saint, Agnes of Rome, which encouraged its wide use. Agnes was the third most popular name for women in the English language, English speaking world for more than 400 years. Its medieval pronunciation was ''Annis'', and its usage and many of its forms coincided with the equally popular name Anna (given name), Anna, related in medieval and Elizabethan times to ''Agnes'', though Ann ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacus Felicitatis
Lacus Felicitatis (Latin ''fēlīcitātis'', "Lake of Happiness") is a small patch of the lunar surface that has been inundated by flows of lava, leaving a level patch with a lower albedo than the surrounding ground. It is located in Terra Nivium, an area of continental ground to the north of the Mare Vaporum. About 70–80 km to the northeast of this area are the Montes Haemus, along the southwestern edge of the Mare Serenitatis. The selenographic coordinates of the centre of Lacus Felicitatis are 18.5° N, 5.4° E, and it has a maximum extent of 98 km. In outline it has a bent shape, with a wing to the northwest and another to the east. The border is somewhat uneven, and it is surrounded by rugged lunar surface. Three tiny craters within this formation have been assigned names by the IAU. These are listed below. Ina is a semi-circular depression that is only about 30 m deep and is difficult to image from the Earth. In November 2006, it was suggested that Ina wa ...

Ina (crater)
Ina is a peculiar small depression ("crater" in IAU nomenclature) on the Moon, in Lacus Felicitatis. It is , wide and 64 m deep (from the deepest point of the bottom to the highest point of the rim). Ina is remarkable for several dozens low hills with flat or rounded tops and very sharp rounded boundaries, looking like drops of mercury. Their surface looks like the usual surface of the Moon while the space between them is very different. Ina is the most prominent of several dozen similar features on the Moon. Their origin is unclear. Discovery, exploration and naming Ina was discovered on photographs taken in 1971 by the crew of Apollo 15 from lunar orbit. It could have been found 5 years earlier on images taken by Lunar Orbiter 4 had a photographic flaw not prevented this. At the end of 1972 Ina was observed and photographed by the crew of Apollo 17. After Apollo it was reconnoitred by several orbiting spacecraft beginning in 2009 when the Lunar Reconnaissance Orbiter ob ...

Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to Moon landing, land on the Moon. 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 Moo ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
