Kosmos 955
Kosmos 955 (; International Designator: 1977-091A, satcat number 10362) was a Soviet ELINT satellite, launched from the Plesetsk Cosmodrome on September 20, 1977, at 01:01 UTC. The satellite's mass was 2,500 kg. Kosmos 955 had a periapsis of 631 km, apoapsis of 664 km, period inclination of 81.2° and an orbital eccentricity of 0.00235. It was launched by a Vostok-2M carrier rocket. It decayed from orbit on 8 September 2000. Overview The launch of Kosmos 955 has been suggested as the cause of the Petrozavodsk phenomenon. According to the official report (pictured), the satellite contained scientific equipment for the "further exploration of outer space Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a near-perfect vacuum containing a low density of particles, pred ..." as well as tools for making exact measurements of its orbital ...

Vostok-2M
The Vostok-2M (russian: Восток meaning ''"East"''), GRAU index 8A92M was an expendable carrier rocket used by the Soviet Union between 1964 and 1991. Ninety-three were launched, of which one failed. Another was destroyed before launch. It was originally built as a specialised version of the earlier Vostok-2, for injecting lighter payloads into higher sun-synchronous orbits. It was a member of the R-7 family of rockets, and the last Vostok. The Vostok-2M made its maiden flight on 28 August 1964, from Site 31/6 at the Baikonur Cosmodrome, successfully placing Kosmos 44, a Meteor weather satellite into orbit. Its only launch failure occurred on 1 February 1969, when the launch of a Meteor failed due to an upper stage problem. At 16:01 GMT on 18 March 1980, a Vostok-2M exploded during fueling at Plesetsk Site 43/4, ahead of the launch of a Tselina-D satellite, killing 48 people who were working on the rocket at the time.

Kosmos Satellites
The cosmos (, ) is another name for the Universe. Using the word ''cosmos'' implies viewing the universe as a complex and orderly system or entity. The cosmos, and understandings of the reasons for its existence and significance, are studied in cosmologya broad discipline covering scientific, religious or philosophical aspects of the cosmos and its nature. Religious and philosophical approaches may include the cosmos among spiritual entities or other matters deemed to exist outside the physical universe. Etymology The philosopher Pythagoras first used the term ''kosmos'' ( grc, κόσμος, Latinized ''kósmos'') for the order of the universe. Greek κόσμος "order, good order, orderly arrangement" is a word with several main senses rooted in those notions. The verb κοσμεῖν (''κοσμεῖν'') meant generally "to dispose, prepare", but especially "to order and arrange (troops for battle), to set (an army) in array"; also "to establish (a government or regime)" ...

Tselina-D
Tselina () is a Russian military space-based radio surveillance system, originally developed in the former Soviet Union. It is capable of determining the exact location of radio-emitting objects and also their type, modes of operation, and how active they are. For instance, preparation for a military operation may raise the activity of the radio communications. Detection of these communications by a space-based surveillance system can provide early warning of this activity, warning that may be unavailable by other means. Variants Initially divided into "overview" (Tselina-O) and "detailed" (Tselina-D), since about 1980 the system has been integrated into a single satellite, Tselina-P, which is also known as Tselina-2. The system's primary subject is enemy radar equipment. Tselina has been numbered as part of the Kosmos series. In total 130 Tselina satellites have been launched. * Tselina-O satellites were launched using Kosmos-3M rockets. * Tselina-D used the Vostok-2M and ...

Outer Space
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is . The plasma between galaxies is thought to account for about half of the baryonic (ordinary) matter in the universe, having a number density of less than one hydrogen atom per cubic metre and a kinetic temperature of millions of kelvins. Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces. Obser ...

Science News
''Science News (SN)'' is an American bi-weekly magazine devoted to articles about new scientific and technical developments, typically gleaned from recent scientific and technical journals. History ''Science News'' has been published since 1922 by Society for Science & the Public, a non-profit organization founded by E. W. Scripps in 1920. American chemist Edwin Slosson served as the publication's first editor. From 1922 to 1966, it was called ''Science News Letter''. The title was changed to ''Science News'' with the March 12, 1966 issue (vol. 89, no. 11). Tom Siegfried was the editor from 2007 to 2012. In 2012, Siegfried stepped down, and Eva Emerson became the Editor in Chief of the magazine. In 2017, Eva Emerson stepped down to become the editor of a new digital magazine, Annual Reviews. On February 1, 2018 Nancy Shute became the Editor in Chief of the magazine. In April 2008, the magazine changed from a weekly format to the current biweekly format, and the website w ...

Petrozavodsk Phenomenon
The Petrozavodsk phenomenon was a series of celestial events of a disputed nature that occurred on 20 September 1977. The sightings were reported over a vast territory, from Copenhagen and Helsinki in the west to Vladivostok in the east. It is named after the city of Petrozavodsk in Russia, Soviet Union, where a glowing object was widely reported that showered the city with numerous rays. Government officials from northern European countries sent letters to Anatoly Aleksandrov, president of the Academy of Sciences of the USSR, expressing concern about whether the observed phenomenon was caused by Soviet weapons testing and whether it constituted a threat to the region's environment. Since 1977, the phenomenon has been often, though not universally, attributed to the launch of the Soviet satellite '' Kosmos-955''. In the same year, a preliminary report for the Academy of Sciences of the USSR was made, containing a large body of visual observations, radiolocation reports, physical ...

Orbital Eccentricity
In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle. A value of 0 is a circular orbit, values between 0 and 1 form an elliptic orbit, 1 is a parabolic escape orbit (or capture orbit), and greater than 1 is a hyperbola. The term derives its name from the parameters of conic sections, as every Kepler orbit is a conic section. It is normally used for the isolated two-body problem, but extensions exist for objects following a rosette orbit through the Galaxy. Definition In a two-body problem with inverse-square-law force, every orbit is a Kepler orbit. The eccentricity of this Kepler orbit is a non-negative number that defines its shape. The eccentricity may take the following values: * circular orbit: ''e'' = 0 * elliptic orbit: 0 < ''e'' < 1 * [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

International Designator
The International Designator, also known as COSPAR ID, is an international identifier assigned to artificial objects in space. It consists of the launch year, a three-digit incrementing launch number of that year and up to a three-letter code representing the sequential identifier of a piece in a launch. In TLE format the first two digits of the year and the dash are dropped. For example1990-037Ais the Space Shuttle ''Discovery'' on mission STS-31, which carried the Hubble Space Telescope1990-037B into space. This launch was the 37th known successful launch worldwide in 1990. The designation system has been generally known as the COSPAR system, named for the Committee on Space Research (COSPAR) of the International Council for Science. COSPAR subsumed the first designation system, devised at Harvard University. That system used letters of the Greek alphabet to designate artificial satellites. This was based on the scientific naming convention for natural satellites. For exampl ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Apoapsis
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, the apsides of the Earth are called the aphelion and perihelion. General description There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ''ap-'', ''apo-'' (), or ''peri-'' (), each referring to the farthest and closest point to the primary body the affixing necessary suffix that describes the primary body in the orbit. In this case, the suffix for Earth is ''-gee'', so the apsides' names are ''apogee'' and ''perigee''. For the Sun, its suffix is ''-helion'', so the names are ''aphelion'' and ''perihelion''. According to Newton's laws of motion, all periodic orbits are ellipses. The barycenter of the two bodies may lie well within the bigger body—e.g., the Earth–Moon barycenter is about 75% of the way from Earth's center to its surface. If, compared to the larger mass, the smaller mass is negligible (e.g., ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
