Kant (crater)
Kant is a small Lunar craters, lunar impact crater that is located to the northwest of the prominent crater Cyrillus (crater), Cyrillus and the comparably sized Ibn-Rushd (crater), Ibn Rushd. To the northwest is Zöllner (crater), Zöllner, and to the east is Mons Penck. This last feature forms a mountainous promontory reaching a height of about 4 km. The crater is named after the German philosopher Immanuel Kant. This crater has a well-defined and somewhat uneven rim that is roughly circular in shape. The inner walls have a higher albedo than the surrounding surface, giving them a lighter appearance. Parts of the inner wall have slumped across the inner floor, producing an irregular surface. At the midpoint of the interior is a low central rise, with a craterlet at the summit, giving the appearance of terrestrial volcano, although the peak is probably not volcanic. Satellite craters By convention these features are identified on lunar maps by placing the letter on the si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric Polar orbit, 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 LCROSS, 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. ...

Zöllner (crater)
Zöllner is a lunar impact crater located to the west of Sinus Asperitatis. It was named after German astrophysicist and astronomer Johann Karl Friedrich Zöllner., accessed 20 February 2019 To the north is the smaller crater Alfraganus and to the northwest lies the oval-shaped Taylor. Southeast of Zöllner is the smaller crater Kant. The rim of Zöllner forms an irregular oval, with the formation being longer in a north–south direction. The wall is low and worn, with a distorted, crater-like depression attached to the southeast of the rim. The narrow floor still retains a central peak. The Apollo 16 Apollo 16 (April 1627, 1972) was the tenth human spaceflight, crewed mission in the United States Apollo program, Apollo space program, administered by NASA, and the fifth and penultimate to Moon landing, land on the Moon. It was the second o ... landing site is located about 80 kilometers west-southwest of the crater rim. Satellite craters By convention these features a ...

Jonathan's Space Report
''Jonathan's Space Report'' (JSR) is a newsletter about the Space Age hosted at Jonathan's Space Page. It is written by Jonathan McDowell, a Center for Astrophysics Harvard & Smithsonian astrophysicist. It is updated as McDowell's schedule permits, but he tries to publish two issues each month. Originally, the website was hosted on a Harvard University account, but it was moved in late 2003 to a dedicated domain. Started in 1989, the newsletter reports on recent space launches, International Space Station activities, spacecraft developments, and newly released space-related data. McDowell's report occasionally corrects NASA The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the federal government of the United States, US federal government responsible for the United States ...'s official web sites, or provides additional data on classified launches that are not available elsewhere ...

Albedo
Albedo ( ; ) is the fraction of sunlight that is Diffuse reflection, diffusely reflected by a body. It is measured on a scale from 0 (corresponding to a black body that absorbs all incident radiation) to 1 (corresponding to a body that reflects all incident radiation). ''Surface albedo'' is defined as the ratio of Radiosity (radiometry), radiosity ''J''e to the irradiance ''E''e (flux per unit area) received by a surface. The proportion reflected is not only determined by properties of the surface itself, but also by the spectral and angular distribution of solar radiation reaching the Earth's surface. These factors vary with atmospheric composition, geographic location, and time (see position of the Sun). While directional-hemispherical reflectance factor is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The temporal resolution may range from seconds ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ibn-Rushd (crater)
Ibn-Rushd is a lunar impact crater located to the northwest of the larger crater Cyrillus. To the northwest is the crater Kant and to the north is Mons Penck, a mountain promontory. The crater is somewhat eroded with age, and the southern rim is overlain by a pair of smaller craters named Cyrillus B and C. The crater floor is relatively flat, and lacks a central peak. In 1976 the crater was named after Ibn Rushd (Latinized as Averroes), the 12th-century Muslim polymath from the Islamic Spain Al-Andalus () was the Muslim-ruled area of the Iberian Peninsula. The name refers to the different Muslim states that controlled these territories at various times between 711 and 1492.

Immanuel Kant
Immanuel Kant (born Emanuel Kant; 22 April 1724 – 12 February 1804) was a German Philosophy, philosopher and one of the central Age of Enlightenment, Enlightenment thinkers. Born in Königsberg, Kant's comprehensive and systematic works in epistemology, metaphysics, ethics, and aesthetics have made him one of the most influential and highly discussed figures in modern Western philosophy. In his doctrine of transcendental idealism, Kant argued that space and time are mere "forms of intuition" that structure all experience and that the objects of experience are mere "appearances". The nature of things as they are in themselves is unknowable to us. Nonetheless, in an attempt to counter the philosophical doctrine of Philosophical skepticism, skepticism, he wrote the ''Critique of Pure Reason'' (1781/1787), his best-known work. Kant drew a parallel to the Copernican Revolution#Immanuel Kant, Copernican Revolution in his proposal to think of the objects of experience as confo ...

Cyrillus (crater)
Cyrillus is a lunar impact crater located on the northwest edge of Mare Nectaris. Intruding into the northeast rim is the slightly larger, and younger crater Theophilus. To the south is another prominent crater named Catharina. Together these three craters form a prominent trio in the southeast quadrant of the Moon. To the northwest is Ibn-Rushd. Cyrillus is named after Saint Cyril of Alexandria, a 5th-century Patriarch and theologian. The floor of Cyrillus contains a reduced central hill and the considerable crater Cyrillus A. The walls of the broken formation of Cyrillus remain intact until the point of junction with Theophilus.Moore, Patrick (2001). ''On the Moon''. Sterling Publishing Co.. . p. 81, 209 Slightly northeast of its center, three rounded mountains rise to heights of 1,000 metres above Cyrillus' floor: Cyrillus Alpha, Delta, and Eta. A tiny crater with bright rays on the east side of Cyrillus has been named Shioli. A point to the east of Shioli is the proposed l ...

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.
