Adlinda (crater)
Adlinda is the third-largest multiring structure (impact crater) on Jupiter's moon Callisto, measuring roughly 1000 km in diameter. It is situated in the southern hemisphere of Callisto. The name is taken from Inuit mythology. The relatively young, large Lofn In Norse mythology, Lofn (Old Norse: , possibly "comforter,"Orchard (1997:104). "the comforter, the mild,"Simek (2007:190). or "loving"Byock (2005:168).) is a goddess. Lofn is attested in the ''Prose Edda'', written in the 13th century by Snorri St ... impact crater is superposed on Adlinda. The bright deposits from this crater cover about 30% of the surface of Adlinda hindering detailed study. Lofn is an example of a flat floored impact crater.

Callisto Lofn PIA01077
CALLISTO (''Cooperative Action Leading to Launcher Innovation in Stage Toss-back Operations'') is a reusable VTVL demonstrator propelled by a small 40 kN Japanese LOX-LH2 rocket engine. It is being developed jointly by the French (CNES), German (DLR) and Japanese (JAXA) national space agencies. The goals for CALLISTO are to mature and demonstrate the technologies which are necessary to build and operate a reusable launch vehicle, but also to better assess the operational cost of such a vehicle. The first flight was originally planned to occur in late 2020; it has since been postponed to 2025 and later to 2026. Following the programme's conclusion, the experiences and technologies gained through CALLISTO will be harnessed to benefit other ongoing and future space programmes, such as the development of the European reusable launcher Ariane Next. CALLISTO is distinct from a similar project ''Themis'' under development by ESA and from the DLR-developed Reusable Flight Experiment ...

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.

Jupiter
Jupiter is the fifth planet from the Sun and the List of Solar System objects by size, largest in the Solar System. It is a gas giant with a Jupiter mass, mass more than 2.5 times that of all the other planets in the Solar System combined and slightly less than one-thousandth the mass of the Sun. Its diameter is 11 times that of Earth and a tenth that of the Sun. Jupiter orbits the Sun at a distance of , with an orbital period of . It is the List of brightest natural objects in the sky, third-brightest natural object in the Earth's night sky, after the Moon and Venus, and has been observed since prehistoric times. Its name derives from that of Jupiter (god), Jupiter, the chief deity of ancient Roman religion. Jupiter was the first of the Sun's planets to form, and its inward migration during the primordial phase of the Solar System affected much of the formation history of the other planets. Jupiter's atmosphere consists of 76% hydrogen and 24% helium by mass, with a denser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Satellite
A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite). Natural satellites are colloquially referred to as moons, a derivation from the Moon of Earth. In the Solar System, there are six planetary satellite systems containing 418 known natural satellites altogether. Seven objects commonly considered dwarf planets by astronomers are also known to have natural satellites: , Pluto, Haumea, , Makemake, , and Eris. As of January 2022, there are 447 other minor planets known to have natural satellites. A planet usually has at least around 10,000 times the mass of any natural satellites that orbit it, with a correspondingly much larger diameter. The Earth–Moon system is a unique exception in the Solar System; at 3,474 kilometres (2,158 miles) across, the Moon is 0.273 times the diameter of Earth and about of its mass. The next largest ratios are the N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Callisto (moon)
Callisto ( ) is the second-largest moon of Jupiter, after Ganymede. In the Solar System it is the third-largest moon after Ganymede and Saturn's largest moon Titan, and nearly as large as the smallest planet Mercury. Callisto is, with a diameter of , roughly a third larger than Earth's Moon and orbits Jupiter on average at a distance of , which is about five times further out than the Moon orbiting Earth. It is the outermost of the four large Galilean moons of Jupiter, which were discovered in 1610 with one of the first telescopes, and is today visible from Earth with common binoculars. The surface of Callisto is the oldest and most heavily cratered in the Solar System. Its surface is completely covered with impact craters. It does not show any signatures of subsurface processes such as plate tectonics or volcanism, with no signs that geological activity in general has ever occurred, and is thought to have evolved predominantly under the influence of impacts.

Inuit Mythology
Inuit religion is the shared spiritual beliefs and practices of the Inuit, an Indigenous peoples of the Americas, indigenous people from Alaska, northern Canada, Greenland, and parts of Siberia. Their religion shares many similarities with some Alaska Native religions. Traditional Inuit religious practices include animism and shamanism, in which spiritual healers mediate with spirits. Today many Inuit follow Christianity (with 71 percent of Canadian Inuit identifying as Christian ); however, traditional Inuit spirituality continues as part of a living, oral tradition and part of contemporary Inuit society. Inuit who balance indigenous and Christian theology practice religious syncretism. Inuit cosmology provides a narrative about the world and the place of people within it. Rachel Qitsualik-Tinsley writes: Traditional stories, rituals, and taboos of the Inuit are often precautions against dangers posed by their harsh Arctic environment. Knud Rasmussen asked his guide and friend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lofn (crater)
Lofn is a large and relatively young impact crater on Jupiter's Galilean satellite Callisto. It was identified in 1997 and named after the goddess of marriage in Norse mythology. Located near the south pole of this moon, Lofn is classified as a flat floored or anomalous dome impact crater. It is superimposed on Adlinda multilayer structure obscuring about 30 percent of it. Another multi-ring structure—Heimdall is found to the south-west of Lofn. Geologically Lofn is divided into a number of zones including the flat central floor zone, ring of massifs around it and the outer rings of bright and dark impact ejecta. Lofn was probably formed by an oblique impactor coming from the north-west. The relative shallowness of it is explained by either fragmentation of the impactor prior to the contact with the surface or by the post impact relaxation of Callisto's ductile crust. Discovery and location Lofn is one of the largest impact craters on Jupiter's moon Callisto. It is located ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface Features Of Callisto (moon)
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth". The concept of surface has been abstracted and formalized in mathematics, specifically in geometry. Depending on the properties on which the emphasis is given, there are several inequivalent such formalizations that are all called ''surface'', sometimes with a qualifier such as algebraic surface, smooth surface or fractal surface. The concept of surface and its mathematical abstractions are both widely used in physics, engineering, computer graphics, and many other disciplines, primarily in representing the surfaces of ph ...
