M-3SII
The Mu, also known as M, was a series of Japanese Solid-fuel rocket, solid-fueled carrier rockets, which were launched from Uchinoura Space Center, Uchinoura between 1966 and 2006. Originally developed by Japan's Institute of Space and Astronautical Science, Mu rockets were later operated by Japan Aerospace Exploration Agency following ISAS becoming part of it. Early Japanese carrier rockets The first Mu rocket, the Mu-1 made a single, sub-orbital, test flight, on 31 October 1966. Subsequently, a series of rockets were produced, designated Mu-3 and Mu-4. In 1969 a suborbital test launch of the Mu-3D was conducted. The first orbital launch attempt for the Mu family, using a Mu-4, Mu-4S, was conducted on 25 September 1970, however the fourth stage did not ignite, and the rocket failed to reach orbit. On 16 February 1971, Tansei 1 was launched by another Mu-4S rocket. Two further Mu-4S launches took place during 1971 and 1972. The Mu-4S was replaced by the Mu-3C, was launched four ti ...

Tsyklon-3
The Tsyklon-3, also known as Tsiklon-3 and Cyclone-3 (known as SL-14 by the United States DoD), GRAU index 11K68, was a Soviet, and subsequently Ukrainian orbital carrier rocket. Overview Tsyklon-3 launching a Meteor-3 satellite at left A derivative of the R-36 ICBM, and a member of the Tsyklon family, Tsyklon-3 made its maiden flight on 24 June 1977, and was retired on 30 January 2009. The Ukrainian-built Tsyklon rockets were retired in favour of future all-Russian carrier rockets, such as the Angara, and because they were fuelled by toxic hypergolic propellants. Successor Ukraine was developing a commercial derivative of the Tsyklon-3, the Tsyklon-4. The development of Tsyklon-4 ended in 2015 after Ukraine's development partner Brazil pulled out of the project. Tsyklon-4 never made it to launch pad. Another successor to the Tsyklon rockets, Cyclone-4M (based on Tsyklon-4 designs), is under development as of 2021 for use in the commercial market. Debris 2013 lo ...

Plesetsk Cosmodrome Site 132
Plesetsk Cosmodrome () is a Russian spaceport located in Mirny, Arkhangelsk Oblast, near the town of Plesetsk, from which it takes its name. Until 2025 and the commissioning of the Andøya base in Norway, it was the only operational orbital spaceport in Europe and the northernmost spaceport in the world. Originally developed as an intercontinental ballistic missile (ICBM) site for the R-7 missile, its strategic location approximately north of Moscow was key to its selection. Due to its high latitude, Plesetsk is particularly suited for specific types of satellite launches, such as those into Molniya orbits, and historically served as a secondary launch facility. Most Soviet orbital launches were conducted from Baikonur Cosmodrome, located in the Kazakh SSR. However, following the dissolution of the Soviet Union, Baikonur became part of Kazakhstan, which began charging Russia to lease the land for its use. As a result, Plesetsk has seen significantly increased activity since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kosmos-3M
The Kosmos-3M ( meaning "''Cosmos''", GRAU index 11K65M) was a Russian space launch vehicle, member of the Kosmos (rocket family), Kosmos rocket family. It was a liquid-fueled two-stage launch vehicle, first launched in 1967 and with over 420 successful launches to its name. The Kosmos-3M used Unsymmetrical dimethylhydrazine, UDMH fuel and Red fuming nitric acid, AK27I oxidizer (red fuming nitric acid) to lift roughly of payload into orbit. It differed from the earlier Kosmos-3 in its finer control of the second-stage burn, allowing operators to tune the thrust and even channel it through nozzles that helped orient the rocket for the launching of multiple satellites at one time. Production Corporation Polyot, PO Polyot manufactured these launch vehicles in the Russian city of Omsk for decades. It was originally scheduled to be retired from service in 2011; however, in April 2010 the Commander of the Russian Space Forces confirmed that it would be retired by the end of 2010. On ...

Zenit (satellite)
Zenit (, , Zenith) was a series of military photoreconnaissance satellites launched by the Soviet Union The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet ... between 1961 and 1994. To conceal their nature, all flights were given the public Kosmos designation. Description The basic design of the Zenit satellites was similar to the Vostok crewed spacecraft, sharing the return and service modules. It consisted of a spherical re-entry capsule in diameter with a mass of around . This capsule contained the camera system, its film, recovery beacons, parachutes and a destruct charge. In orbit, this was attached to a service module that contained batteries, electronic equipment, an orientation system and a liquid-fuelled rocket engine that would slow the Zenit for re-entry, before th ...

Baikonur Cosmodrome Site 1
Gagarin's Start (, ''Gagarinskiy start''), also known as Baikonur Site 1 or Site 1/5 was a launch site at the Baikonur Cosmodrome in Kazakhstan that was used by the Soviet space program and Roscosmos. History 20th century The launchpad for the world's first human spaceflight made by Yuri Gagarin on Vostok 1 in 1961, the site was referred to as Site No.1 (, ''Ploshchadka No. 1'') as the first one of its kind. It is also sometimes referred to as NIIP-5 LC1, Baikonur LC1, LC-1/5, LC-1, Pad 1/5 or GIK-5 LC1. At Baikonur, site numbers refer to facilities. Site 0 was the construction headquarters and residential area and, as the first major project, this launch pad was named Site 1. Its processing facilities were called Site 2 and its oxygen/nitrogen plant was Site 3. The facility was later designated as Pad No. 5 for the R-7 programme. The numbering of the sites reflected Baikonur's role as a secondary ICBM base, with the primary being the Plesetsk Cosmodrome, which featured ...

Molniya Orbit
A Molniya orbit ( rus, Молния, p=ˈmolnʲɪjə, a=Ru-молния.ogg, "Lightning") is a type of satellite orbit designed to provide communications and remote sensing coverage over high latitudes. It is a highly elliptical orbit with an inclination of 63.4 degrees, an argument of perigee of 270 degrees, and an orbital period of approximately half a sidereal day. The name comes from the '' Molniya'' satellites, a series of Soviet/Russian civilian and military communications satellites which have used this type of orbit since the mid-1960s. A variation on the Molniya orbit is the so-called Three Apogee (TAP) orbit, whose period is a third of a sidereal day. The Molniya orbit has a long dwell time over the hemisphere of interest, while moving very quickly over the other. In practice, this places it over either Russia or Canada for the majority of its orbit, providing a high angle of view to communications and monitoring satellites covering these high-latitude ar ...

NPO Prikladnoi Mekhaniki
JSC Information Satellite Systems Reshetnev () is a Russian satellite manufacturing company. It is based in the closed city of Krasnoyarsk-26 (today called Zheleznogorsk, Krasnoyarsk Krai, Zheleznogorsk), Krasnoyarsk Krai near the city of Krasnoyarsk. The company was formerly called NPO PM (short for NPO Prikladnoi Mekhaniki or Applied Mechanics Science-Production Association; NPO stands for Nauchno-proizvodstvennoye obyedineniye, Scientific Production Association). History The company was founded in 1959 by as the Eastern office of Energia (corporation), OKB-1. During its history, it has built 27 different space systems and over a thousand individual satellites. In particular, the company was responsible for designing the GLONASS satellite navigation system. After the dissolution of the Soviet Union, the company lost most of its state financing, and its work force of 8,000 was cut almost in half. In 1995, Information Satellite System signed a co-operation agreement with the Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molniya (satellite)
The Molniya ( rus, Молния, p=ˈmolnʲɪjə, a=Ru-молния.ogg, "Lightning") series satellites were military and communications satellites launched by the Soviet Union from 1965 to 1991, and by the Russian Federation from 1991 to 2004. These satellites used highly eccentric elliptical orbits known as Molniya orbits, which have a long dwell time over high latitudes. They are suited for communications purposes in polar regions, in the same way that geostationary satellites are used for equatorial regions. There were 164 Molniya satellites launched, all in Molniya orbits with the exception of Molniya 1S which was launched into geostationary orbit for testing purposes. History In the early 1960s, when Europe and America were establishing geostationary communication satellites, the Russians found these orbits unsuitable. They were limited in the amount of rocket power available and it is extremely energy intensive to both launch a satellite to 40,000 km, and change it ...

Plesetsk Cosmodrome Site 43
Plesetsk Cosmodrome Site 43, is a launch complex at the Plesetsk Cosmodrome in Russia. It consists of two pads, Sites 43/3 and 43/4 (also known as SK-3 and SK-4) and has been used by R-7-derived rockets since the early 1960s. , both pads remain in use for the Soyuz-2.1a and Soyuz-2.1b Soyuz2 (; GRAU index: 14A14) is a Russian expendable medium-lift launch vehicle and the seventh major iteration of the Soyuz rocket family. Compared to its predecessors, Soyuz-2 features significant upgrades, including improved engines and ... rockets. Additionally, Site 43/4 also hosts launches of the smaller Soyuz-2.1v launch vehicle. Originally constructed for the R-7A Semyorka missiles, the site hosted its first launch on 21 December 1965, when an R-7A test flight was conducted from Site 43/3. The first launch from Site 43/4 followed on 25 July 1967. After its decommissioning as a missile base, the complex was repurposed for space launches. The first orbital launch occurred on 3 D ...

Molniya-M
The Molniya-M (, GRAU index: 8K78M) was a Soviet and Russian launch vehicle derived from the R-7 Semyorka Intercontinental ballistic missile (ICBM). The original 8K78 booster had been the product of a rushed development program and its launch record was no better than the 8K72 Luna booster of 1958–1960. As 1962 ended, there had been 12 launches of 8K78s, ten of which failed (five Block L failures, four Block I failures, and one failure caused by the Block A core stage). The two successful launches had had their probes ( Venera 1 and Mars 1) fail en route to their respective planetary targets. As such, work began at the Korolev Bureau to improve the basic 8K78 vehicle. The core and strap-ons received the up-rated 8D74M engines and the Kosberg Bureau completely redesigned the Block I stage. The Block L engine was also slightly enhanced. The first six 8K78Ms built used RD-0108 engines in the Block I stage, which was also used in the two crewed Voskhod boosters, all subseque ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a Transponder (satellite communications), transponder; it creates a communication channel between a source transmitter and a Radio receiver, receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The radio waves used for telecommunications links travel by Line-of-sight propagation, line of sight and so are obstructe ...
