Séítah
Jezero is a crater on Mars in the Syrtis Major quadrangle, about in diameter. Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. The lake in the crater was present when valley networks were forming on Mars. Besides having a delta, the crater shows point bars and inverted channels. From a study of the delta and channels, it was concluded that the lake inside the crater probably formed during a period in which there was continual surface runoff. In 2007, following the discovery of its ancient lake, the crater was named after Jezero, Bosnia and Herzegovina, one of several eponymous towns in the country. In some Slavic languages, the word , sh-Latn-Cyrl, jezero, језеро, separator=" / ", Czech, sl, jezero and its closest written variations ( pl, jezioro, dsb, jezer, sk, jazero, Russian and uk, озеро), as well as in Baltic languages ( lt, ežeras, lv, ezers) means 'lake'.

Mars 2020
Mars 2020 is a Mars rover mission forming part of NASA's Mars Exploration Program that includes the rover ''Perseverance'', the small robotic, coaxial helicopter '' Ingenuity'', and associated delivery vehicles. Mars 2020 was launched from Earth on an Atlas V launch vehicle at 11:50:01 UTC on 30 July 2020, and confirmation of touch down in the Martian crater Jezero was received at 20:55 UTC on 18 February 2021. On 5 March 2021, NASA named the landing site of the rover Octavia E. Butler Landing. As of , ''Perseverance'' and ''Ingenuity'' have been on Mars for sols ( total days; '). ''Perseverance'' will investigate an astrobiologically relevant ancient environment on Mars and investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of past life on Mars, and the potential for preservation of biosignatures within accessible geological materials. It will cache sample containers along its route for retr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perseverance (rover)
''Perseverance'', nicknamed ''Percy'', is a car-sized Mars rover designed to explore the Jezero crater on Mars as part of NASA's Mars 2020 mission. It was manufactured by the Jet Propulsion Laboratory and launched on July 30, 2020, at 11:50 UTC. Confirmation that the rover successfully landed on Mars was received on February 18, 2021, at 20:55 UTC. As of , ''Perseverance'' has been active on Mars for sols ( Earth days, or ) since its landing. Following the rover's arrival, NASA named the landing site Octavia E. Butler Landing. ''Perseverance'' has a similar design to its predecessor rover, ''Curiosity'', although it was moderately upgraded. It carries seven primary payload instruments, nineteen cameras, and two microphones. The rover also carried the mini-helicopter '' Ingenuity'' to Mars, an experimental aircraft and technology testbed that made the first powered flight on another planet on April 19, 2021. As of December 22, 2022, it has made 37 successful flights. '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Czech Language
Czech (; Czech ), historically also Bohemian (; ''lingua Bohemica'' in Latin), is a West Slavic language of the Czech–Slovak group, written in Latin script. Spoken by over 10 million people, it serves as the official language of the Czech Republic. Czech is closely related to Slovak, to the point of high mutual intelligibility, as well as to Polish to a lesser degree. Czech is a fusional language with a rich system of morphology and relatively flexible word order. Its vocabulary has been extensively influenced by Latin and German. The Czech–Slovak group developed within West Slavic in the high medieval period, and the standardization of Czech and Slovak within the Czech–Slovak dialect continuum emerged in the early modern period. In the later 18th to mid-19th century, the modern written standard became codified in the context of the Czech National Revival. The main non-standard variety, known as Common Czech, is based on the vernacular of Prague, but is now spoken as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay Minerals
Clay minerals are hydrous aluminium phyllosilicates (e.g. kaolin, Al2 Si2 O5( OH)4), sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them. They are important constituents of soils, and have been useful to humans since ancient times in agriculture and manufacturing. Properties Clay is a very fine-grained geologic material that develops plasticity when wet, but becomes hard, brittle and non–plastic upon drying or firing. It is a very common material, and is the oldest known ceramic. Prehistoric humans discovered the useful properties of clay and used it for making pottery. The chemistry of clay, including its capacity to retain nutrient cations such as potassium and ammonium, is important to soil fertility. Because the individual particles in clay are less tha ...

Planetary And Space Science
''Planetary and Space Science'' (P&SS), published 15 times per year, is a peer-reviewed scientific journal established in 1959. It publishes original research articles along with short communications (letters). The main topic is Solar System processes which encompasses multiple areas of the natural sciences. Numerical simulations of solar system processes are also conducted at ground-based facilities or on-board space platforms. The editor-in-chief is Maria Cristina De Sanctis (National Institute of Astrophysics, Roma, Italy). It is published by Elsevier. Scope Research that involves planetary and space sciences involves many disciplines, which is reflected by the scope of the journal. Basic science Celestial mechanics is part of these studies, as this science includes understanding the dynamic evolution of the Solar System, relativistic effects, among other areas of analysis and consideration. Cosmochemistry is also part of the published research in this journal. Cosmochem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ScienceDaily
''Science Daily'' is an American website launched in 1995 that aggregates press releases and publishes lightly edited press releases (a practice called churnalism) about science, similar to Phys.org and EurekAlert!. The site was founded by married couple Dan and Michele Hogan in 1995; Dan Hogan formerly worked in the public affairs department of Jackson Laboratory writing press releases. The site makes money from selling advertisements. As of 2010, the site said that it had grown "from a two-person operation to a full-fledged news business with worldwide contributors". At the time, it was run out of the Hogans' home, had no reporters, and only reprinted press releases. In 2012, Quantcast Quantcast is an American technology company, founded in 2006, that specializes in AI-driven real-time advertising, audience insights and measurement. It has offices in the United States, Canada, Australia, Singapore, United Kingdom, Ireland, Fran ... ranked it at 614 with 2.6 million U.S. vi ...

Navajo Language
Navajo or Navaho (; Navajo: or ) is a Southern Athabaskan language of the Na-Dené family, through which it is related to languages spoken across the western areas of North America. Navajo is spoken primarily in the Southwestern United States, especially on the Navajo Nation. It is one of the most widely spoken Native American languages and is the most widely spoken north of the Mexico–United States border, with almost 170,000 Americans speaking Navajo at home as of 2011. The language has struggled to keep a healthy speaker base, although this problem has been alleviated to some extent by extensive education programs in the Navajo Nation, including the creation of versions of the films Finding Nemo and Star Wars dubbed into Navajo. The United States in World War II used the Navajo language to develop a system of code talkers to relay messages that could not be cracked. Navajo has a fairly large phoneme inventory, including several uncommon consonants that are not found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
