Kosmos 917
Kosmos 917 (russian: Космос 917 meaning ''Cosmos 917'') was a Soviet US-K missile early warning satellite which was launched in 1977 as part of the Soviet military's Oko programme. The satellite was designed to identify missile launches using optical telescopes and infrared sensors. Kosmos 917 was launched from Site 43/4 at Plesetsk Cosmodrome in the Russian SSR. A Molniya-M carrier rocket with a 2BL upper stage was used to perform the launch, which took place at 04:44 UTC on 16 June 1977. The launch successfully placed the satellite into a molniya orbit. It subsequently received its Kosmos designation, and the international designator 1977-047A. The United States Space Command assigned it the Satellite Catalog Number 10059. It self-destructed on 8 June 1978. The primary portion of it re-entered on 4 January 2023, but several pieces of its debris still remain in orbit.

Early Warning Satellite
An early warning satellite is a satellite designed to rapidly detect ballistic missile launches and thus enable defensive military action. To do this, these satellites use infrared detectors that identify the missile thanks to the heat given off by its engines during the propulsion phase. This type of satellite was developed in the 1960s in the context of the Cold War in order to activate early warning systems in the target territories of a missile attack. It later became a component of missile defense systems, as well as regulatory control systems for nuclear tests. Only the two main nuclear powers, Russia and the United States, have a constellation of early warning satellites. Description The objective of an early warning satellite is to detect the launch of a ballistic missile at the beginning of its trajectory, when its detection is possible since its propulsion system gives off heat. For a typical ICBM fired from a distance of 10,000 km, this propulsive phase lasts ... [...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] |
Spacecraft Launched By Molniya-M Rockets
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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)" ...

Kosmos (satellite)
Kosmos (russian: Ко́смос, , meaning " (outer) space" or " Kosmos") is a designation given to many satellites operated by the Soviet Union and subsequently Russia. Kosmos 1, the first spacecraft to be given a Kosmos designation, was launched on 16 March 1962. History The first Soviet satellites orbiting Earth were named Sputnik, Polyot (starting in 1963), Elektron (in 1964), Proton (in 1965), and Molniya (in 1965), but most have been called Kosmos since Kosmos 1 on 16 March 1962. The program has included uncrewed tests of crewed spacecraft and satellites for scientific research and military purposes. , 2548 Kosmos satellites have been launched. The spacecraft do not form a single programme, but instead consist of almost all Soviet and Russian military satellites, as well as a number of scientific satellites, and spacecraft which failed during or immediately after launch, but still reached orbit. Most Soviet and subsequently Russian military satellites were given Kosm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US-K
Upravlyaemy Sputnik Kontinentalny (russian: Управляемый Спутник Континентальный meaning ''Continental Controllable Satellite'') or US-K (russian: УС-К) is a series of Russian, previously Soviet, satellites used to detect missile launches as part of the Oko system. It consists of a constellation of satellites, usually in molniya orbits, designated under the Kosmos system. The satellites are built by the company NPO Lavochkin and are launched on Molniya-M rockets. Oko can be directly translated as the Russian word for eye. As of June 2014, only two of the eight satellites in orbit were still functional, rendering the system inoperable. History US-K are the first generation of Oko satellites, the first of which was launched in 1972. The vast majority of the satellites launched (86 out of 100 as of March 2012 ) have been US-K satellites in molniya orbits. Seven first generation satellites were launched into geosynchronous orbits, called US-KS, sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
