Yantar (satellite)
Yantar ( rus, Янтарь meaning amber) is a series of Russian (previously Soviet) reconnaissance satellites, which supplemented and eventually replaced the Zenit spacecraft. Kosmos 2175, a Yantar-4K2 or ''Kobalt'' spacecraft, was the first satellite to be launched by the Russian Federation following the dissolution of the Soviet Union. Yantar-Terilen was the first real-time digital system. Yantar satellites also formed the basis for the later Orlets, Resurs and Persona satellites. 179 have been launched, nine of which were lost in launch failures. All Yantar satellites were launched using the Soyuz-U carrier rocket until Kosmos 2480 in 2012 which was announced as the last launch of that rocket from Plesetsk. Subsequent launches used the modernized Soyuz-2.1a rocket. The last Yantar mission was Kosmos 2505, a Yantar-4K2M or ''Kobalt-M'', launched on 5 June 2015. Reconnaissance missions have been taken over by the Persona class of satellites. History In 1964, Soviet design bu ...

GRAU Index
The Main Missile and Artillery Directorate of the Ministry of Defense of the Russian Federation (), commonly referred to by its transliterated Russian acronym GRAU (), is a department of the Russian Ministry of Defense. It is subordinate to the Chief of Armament and Munition of the Russian Armed Forces, a vice-minister of defense. The organization dates back to 1862 when it was established under the name Главное артиллерийское управление (ГАУ – GAU). The "R" from "rockets" was added to the title in 1960. In particular, the GRAU is responsible for assigning GRAU indices to Russian army munitions and equipment. Arsenals of the GRAU, according to Kommersant-Vlast in 2005, include the 60th at Kaluga, the 55th at Rzhev, the 75th at Serpukhov south of Moscow, (all three in the Moscow Military District) and the 80th at Gagarskiy, the 116th at Krasno-Oktyabrskiy and the 5th, all in the Volga–Urals Military District.Kommersant-Vlast, Vys Rossi ...

Neman, Russia
Neman (russian: Не́ман; german: Ragnit; lt, Ragainė; pl, Ragneta), is a town and the administrative center of Nemansky District in Kaliningrad Oblast, Russia, located in the historic region of Lithuania Minor, on the steep southern bank of the Neman River, where it forms the Russian border with the Klaipėda Region in Lithuania, and northeast of Kaliningrad, the administrative center of the oblast. Population figures: History ''Ragnita'' (from Old Prussian: ''ragas'', "spur"), founded in 1288, was a settlement of the Baltic (Old Prussian) tribe of Skalvians. It was contested by the Grand Duchy of Lithuania since its creation in the 13th century, and on April 23, 1289 it was conquered by the Teutonic Knights, who built a castle there between 1397 and 1409, which later became the seat of a ''Komtur''. Construction works were supervised by the Master of the Teutonic Order Konrad Fellenstein of Marienburg. A few decades later, a now-destroyed 25 meter guard tower ...

Terylene
Polyethylene terephthalate (or poly(ethylene terephthalate), PET, PETE, or the obsolete PETP or PET-P), is the most common thermoplastic polymer resin of the polyester family and is used in fibres for clothing, containers for liquids and foods, and thermoforming for manufacturing, and in combination with glass fibre for engineering resins. In 2016, annual production of PET was 56 million tons. The biggest application is in fibres (in excess of 60%), with bottle production accounting for about 30% of global demand. In the context of textile applications, PET is referred to by its common name, polyester, whereas the acronym ''PET'' is generally used in relation to packaging. Polyester makes up about 18% of world polymer production and is the fourth-most-produced polymer after polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC). PET consists of repeating (C10H8O4) units. PET is commonly recycled, and has the digit 1 (♳) as its resin identification code (RIC). T ...

Cobalt
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments ( cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was for a long time thought to be due to the known metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Silhouette
A silhouette ( , ) is the image of a person, animal, object or scene represented as a solid shape of a single colour, usually black, with its edges matching the outline of the subject. The interior of a silhouette is featureless, and the silhouette is usually presented on a light background, usually white, or none at all. The silhouette differs from an line art, outline, which depicts the edge of an object in a linear form, while a silhouette appears as a solid shape. Silhouette images may be created in any visual artistic medium, but were first used to describe pieces of cut paper, which were then stuck to a backing in a contrasting colour, and often framed. Cutting portraits, generally in profile, from black card became popular in the mid-18th century, though the term ''silhouette'' was seldom used until the early decades of the 19th century, and the tradition has continued under this name into the 21st century. They represented a cheap but effective alternative to the portrai ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Comet
A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process that is called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times Earth's diameter, while the tail may stretch beyond one astronomical unit. If sufficiently bright, a comet may be seen from Earth without the aid of a telescope and may subtend an arc of 30° (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures and religions. Comets usually have highly eccentric elliptical orbits, and they have a wide range of orbital periods, ranging from several years to potentially several mill ...

Octane
Octane is a hydrocarbon and an alkane with the chemical formula , and the condensed structural formula . Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. One of these isomers, 2,2,4-Trimethylpentane, 2,2,4-trimethylpentane (commonly called iso-octane) is used as one of the standard values in the octane rating scale. Octane is a component of gasoline (petrol). As with all low-molecular-weight hydrocarbons, octane is volatility (chemistry), volatile and very flammable. Use of the term in gasoline "Octane" is colloquially used as a short form of "octane rating," particularly in the expression "high octane". "Octane rating" is an index of a fuel's ability to resist engine knock in engines having different compression ratios, which is a characteristic of octane's branched-chain isomers, especially iso-octane. The octane rating of gasoline is not directly related to the power output of an engine. Using gasoline of a higher o ...
