Soyuz-2.1b
Soyuz-2 ( GRAU index 14A14) is a modernized version of the Soviet Soyuz rocket. In its basic form, it is a three-stage launch vehicle for placing payloads into low Earth orbit. Compared to the previous versions of the Soyuz, the first-stage boosters and two core stages feature uprated engines with improved injection systems. Digital flight control and telemetry systems allow the rocket to be launched from a fixed launch platform, whereas the launch platforms for earlier Soyuz rockets had to be rotated as the rocket could not perform a roll to change its heading in flight. Soyuz-2 is often flown with an upper stage, which allows it to lift payloads into higher orbits, such as Molniya and geosynchronous orbits. The upper stage is equipped with independent flight control and telemetry systems from those used in the rest of the rocket. The NPO Lavochkin manufactured Fregat is the most commonly used upper stage. Soyuz-2 rockets were first launched from Site 31 at the Baiko ...

Fregat
Fregat (russian: Фрегат, ''frigate'') is an upper stage developed by NPO Lavochkin in the 1990s, which is used in some Soyuz and Zenit launch vehicles, but is universal and can be used as a part of a medium and heavy class launch vehicles. Fregat became operational in February 2000. Its liquid propellant engine uses UDMH and N2O4. Fregat's success rate is 97.8% (with 2 failures in 93 launches), which makes it one of the most reliable upper stages in the world. Fregat has successfully delivered more than 300 payloads into different orbits. It remains the only upper stage in the world that can place its payload into 3 or more different orbits in a single launch. Description The Fregat upper stage is designed for injecting large payloads into a low, medium-height or high geosynchronous orbit. Fregat is a versatile upper stage, in addition to orbital insertion, it can be used as an escape stage to send modern space probes into interplanetary trajectories (e.g. Venus Express ...

RD-107
The RD-107 and its sibling, the RD-108, are a type of rocket engine initially used to launch R-7 Semyorka missiles. RD-107 engines were later used on space launch vehicles based on the R-7. , very similar RD-107A and RD-108A engines are used to launch the Soyuz-2.1a, and Soyuz-2.1b, which are in active service. Design The RD-107 was designed under the direction of Valentin Glushko at the Experimental Design Bureau (OKB-456) between 1954 and 1957. It uses liquid oxygen and kerosene as propellants operating in a gas generator cycle. As was typical by all the descendants of the V-2 rocket technology, the turbine is driven by steam generated by catalytic decomposition of H₂O₂. The steam generator uses solid ''F-30-P-G'' catalyst. These are based on a variable sized pellet covered in an aqueous solution of potassium permanganate and sodium. Each engine uses four fixed main combustion chambers. The RD-107 has an additional two vernier combustion chambers that can thrust vecto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soyuz (rocket Family)
Soyuz (russian: Союз, meaning "union", GRAU index 11A511) is a family of expendable Russian and Soviet carrier rockets developed by OKB-1 and manufactured by Progress Rocket Space Centre in Samara, Russia. With over 1,900 flights since its debut in 1966, the Soyuz is the most frequently used launch vehicle in the world as of 2021. For nearly a decade, between the final flight of the Space Shuttle program in 2011 and the 2020 first crewed mission of SpaceX's Falcon 9 rocket, Soyuz rockets were the only launch vehicles able and approved for transporting astronauts to the International Space Station. The Soyuz vehicles are used as the launcher for the crewed Soyuz spacecraft as part of the Soyuz programme, as well as to launch uncrewed Progress supply spacecraft to the International Space Station and for commercial launches marketed and operated by Starsem and Arianespace. All Soyuz rockets use RP-1 and liquid oxygen (LOX) propellant, with the exception of the Soyuz-U2, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vostochny Cosmodrome
The Vostochny Cosmodrome (russian: Космодром Восточный, ''Kosmodrom Vostochny'', "Eastern Spaceport") is a Russian spaceport (still partly under construction) above the 51st parallel north in the Amur Oblast, in the Russian Far East. It is intended to reduce Russia's dependency on the Baikonur Cosmodrome in Kazakhstan. The first launch took place on 28 April 2016 at 02:01 UTC. As of 1 July 2022, eleven launch attempts have been made with ten successes. Location Vostochny (which means "Eastern" in Russian) is in the Svobodny and Shimanovsk districts of Amur Oblast in the Russian Far East, on the watershed of the Zeya and Bolshaya Pyora rivers, approximately from the Pacific Ocean, depending on launch azimuth. The planned total area is about 30 km in diameter, thus 551.5 km2, centred on . The nearby train station is Ledyanaya and the nearest city is Tsiolkovsky.

R-7 (rocket Family)
The R-7 family of rockets (russian: Р-7) is a series of rockets, derived from the Soviet R-7 Semyorka, the world's first ICBM. More R-7 rockets have been launched than any other family of large rockets. When Soviet nuclear warheads became lighter, the R-7 turned out to be impractical as a ballistic missile, and there were no other heavy payloads with a military application. However, long-term development has made the rockets useful in the Soviet, and later, Russian space programmes. Their purpose shifted primarily to launching satellites, probes, manned and unmanned spacecraft, and other non-threatening payloads. The R-7 family consists of both missiles and orbital carrier rockets. Derivatives include the Vostok, Voskhod and Soyuz rockets, which as of 2022 have been used for all Soviet, and later Russian human spaceflights. The type has a unique configuration where four break-away liquid-fueled engines surround a central core. The core acts as, in effect, a "second stage" af ...

GLONASS
GLONASS (russian: ГЛОНАСС, label=none, ; rus, links=no, Глобальная навигационная спутниковая система, r=Global'naya Navigatsionnaya Sputnikovaya Sistema, t=Global Navigation Satellite System) is a Russian satellite navigation system operating as part of a radionavigation-satellite service. It provides an alternative to Global Positioning System (GPS) and is the second navigational system in operation with global coverage and of comparable precision. Satellite navigation devices supporting both GPS and GLONASS have more satellites available, meaning positions can be fixed more quickly and accurately, especially in built-up areas where buildings may obscure the view to some satellites. GLONASS supplementation of GPS systems also improves positioning in high latitudes (north or south). Development of GLONASS began in the Soviet Union in 1976. Beginning on 12 October 1982, numerous rocket launches added satellites to the system, unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plesetsk Cosmodrome Site 43
Site 43, also known as SK-3 and SK-4, is a launch complex at the Plesetsk Cosmodrome in Russia. It consists of a two pads, Sites 43/3 and 43/4, and has been used by R-7 derived rockets since the early 1960s. The site was originally built for use by R-7A Semyorka missiles. The first launch to use the complex was an R-7A test on 21 December 1965, from Site 43/3. The first launch from 43/4 followed on 25 July 1967. After its retirement from service as a missile base, it was converted for use as a space launch complex. The first orbital launch was of a Voskhod rocket with Kosmos 313 on 3 December 1969. Both pads were damaged by explosions in the 1980s. At 16:01 UTC on 18 March 1980, 48 people were killed when a Vostok-2M exploded during fueling operations at Pad 4. The disaster injured dozens more, while damaging the pad so severely that it was not used again until 1984. On 18 June 1987, a Soyuz-U The Soyuz-U launch vehicle was an improved version of the original Soyuz roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soyuz MS
The Soyuz MS (; GRAU: 11F732A48) is a revision of the Russian spacecraft series Soyuz first launched in 2016. It is an evolution of the Soyuz TMA-M spacecraft, with modernization mostly concentrated on the communications and navigation subsystems. It is used by Roscosmos for human spaceflight. The Soyuz MS has minimal external changes with respect to the Soyuz TMA-M, mostly limited to antennas and sensors, as well as the thruster placement. The first launch was Soyuz MS-01 on 7 July 2016, aboard a Soyuz-FG launch vehicle towards the International Space Station (ISS). The trip included a two-day checkout phase for the design before docking with the ISS on 9 July 2016. Design A Soyuz spacecraft consists of three parts (from front to back): * A spheroid orbital module, * A small aerodynamic reentry module, * A cylindrical service module with solar panels attached. The first two portions are habitable living space. By moving as much as possible into the orbital module, which d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Progress (spacecraft)
The Progress (russian: Прогресс) is a Russian expendable cargo spacecraft. Its purpose is to deliver the supplies needed to sustain a human presence in orbit. While it does not carry a crew, it can be boarded by astronauts when docked to a space station, hence it is classified as ''crewed'' by its manufacturer. Progress is derived from the crewed Soyuz spacecraft and launches on the same launch vehicle, a Soyuz rocket. Progress has supported space stations as early as Salyut 6 and as recently as the International Space Station (ISS). Each year there are between three and four Progress flights to the ISS. A Progress remains docked until shortly before being replaced with a new one or a Soyuz (which will use the same docking port). Then it is filled with waste, disconnected, and de-orbited, at which point it burns up in the atmosphere. Due to the variation in Progress vehicles flown to the ISS, NASA uses its own nomenclature where "ISS 1P" means the first Progress spacecra ...

Galileo (satellite Navigation)
Galileo is a global navigation satellite system (GNSS) that went live in 2016, created by the European Union through the European Space Agency (ESA), operated by the European Union Agency for the Space Programme (EUSPA), headquartered in Prague, Czech Republic, with two ground operations centres in Fucino, Italy, and Oberpfaffenhofen, Germany. The €10 billion project is named after the Italian astronomer Galileo Galilei. One of the aims of Galileo is to provide an independent high-precision positioning system so European political and military authorities do not have to rely on the US GPS, or the Russian GLONASS systems, which could be disabled or degraded by their operators at any time. The use of basic (lower-precision) Galileo services is free and open to everyone. A fully encrypted higher-precision service is available for free to government-authorized users. Galileo is intended to provide horizontal and vertical position measurements within 1 m precision. Galileo is al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
