Soyuz-u2
The Soyuz-U2 (GRAU index 11A511U2) was a Soviet, later Russian, carrier rocket. It was derived from the Soyuz-U, and a member of the R-7 family of rockets. It featured increased performance compared with the baseline Soyuz-U, due to the use of syntin propellant, as opposed to RP-1 paraffin, used on the Soyuz-U. The increased payload of the Soyuz-U2 allowed heavier spacecraft to be launched, while lighter spacecraft could be placed in higher orbits, compared to those launched by Soyuz-U rockets. In 1996, it was announced that the Soyuz-U2 had been retired, as the performance advantage gained through the use of syntin did not justify the additional cost of its production. The final flight, Soyuz TM-22, occurred on 3 September 1995 from Gagarin's Start in Baikonur. The Soyuz-U2 was first used to launch four Zenit reconnaissance satellites, then it delivered crewed Soyuz spacecraft to space stations Salyut 7 and Mir: missions Soyuz T-12 to T-15 and Soyuz TM-1 to TM-22.

Soyuz-U
Soyuz-U ( GRAU index: 11A511U) was a Soviet and later Russian expendable medium-lift launch vehicle designed by the TsSKB design bureau and constructed at the Progress factory in Samara, Russia. The ''U'' designation stands for ''unified'', as the launch vehicle was the replacement for both the Voskhod rocket and the original Soyuz rocket. The Soyuz-U is part of the R-7 rocket family, which evolved from the R-7 Semyorka, an intercontinental ballistic missile. The first Soyuz-U flight took place on 18 May 1973, carrying as its payload Kosmos 559, a Zenit military surveillance satellite. The final flight of a Soyuz-U rocket took place on 22 February 2017, carrying Progress MS-05 to the International Space Station. Soyuz-U was in use continuously for almost 44 years. Production of R-7 derived launch vehicles peaked in the late 1970s-early 1980s at 55–60 a year. Soyuz-U held the world record of highest launch rate in a year in 1979 with 47 flights until this was bea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carrier Rocket
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload (a crewed spacecraft or satellites) from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxygen, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RP-1
RP-1 (Rocket Propellant-1 or Refined Petroleum-1) and similar fuels like RG-1 and T-1 are highly refined kerosene formulations used as rocket fuel. Liquid-fueled rockets that use RP-1 as fuel are known as kerolox rockets. In their engines, RP-1 is Spray nozzle, atomized, mixed with liquid oxygen (LOX), and ignited to produce thrust. Developed in the 1950s, RP-1 is outwardly similar to other kerosene-based fuels like Jet A and JP-8 used in turbine engines but is manufactured to stricter standards. While RP-1 is widely used globally, the primary rocket kerosene formulations in Russia and other former Soviet countries are RG-1 and T-1, which have slightly higher densities. Compared to other rocket fuels, RP-1 provides several advantages with a few tradeoffs. Compared to liquid hydrogen, it offers a lower specific impulse, but can be stored at ambient temperatures, has a lower explosion risk, and although its specific energy is lower, its higher density results in greater energy de ...

Soyuz T-15
Soyuz T-15 (, ''Union T-15'') was a crewed mission to the Mir and Salyut 7 space stations and was part of the Soyuz programme. It marked the final flight of the Soyuz-T spacecraft, the third generation Soyuz spacecraft, which had been in service for seven years from 1979 to 1986. This mission marked the first time that a spacecraft visited, and docked with, two space stations in the same mission.

Flight to Mir Due to the pressure of launching Mir in time for the 27th Communist Party Congress, mission planners were left without the newer Soyuz-TM spacecraft or any of the planned modules to launch to the station at first. It was decided to launch an older Soyuz-T as Soyuz T-15 on a dual mission to both Mir and Salyut 7. Leonid Kizim and Vladimir Solovyov first d ...

Soyuz T-12
Soyuz T-12 (also known as Salyut 7 EP-4) was the seventh crewed spaceflight to the Soviet space station Salyut 7. The name "Soyuz T-12" is also the name of the spacecraft used to launch and land the mission's three-person crew. The mission occurred in July 1984, during the long-duration expedition Salyut 7 EO-3. During the mission, crew member Svetlana Savitskaya became the first woman to ever perform a spacewalk, and the potential Buran space shuttle pilot, Igor Volk, was given spaceflight experience. Unlike many Soyuz visiting missions, the Soyuz lifeboats were not swapped, and the crew returned to Earth in the same spacecraft in which they launched. Background Igor Volk was a test pilot, and was planned to be the commander of the first Buran spaceflight. The rule introduced following the Soyuz 25 failure insisted that all Soviet spaceflight must have at least one crew member who has been to space before. As a result, it was decided that Volk should have spaceflight exper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salyut 7
Salyut 7 (), also known as DOS-6 (Durable Orbital Station 6) was a space station in low Earth orbit from April 1982 to February 1991. It was first crewed in May 1982 with two crew via Soyuz T-5, and last visited in June 1986, by Soyuz T-15. Various crew and modules were used over its lifetime, including 12 crewed and 15 uncrewed launches in total. Supporting spacecraft included the Soyuz T, Progress (spacecraft), Progress, and TKS (spacecraft), TKS spacecraft. It was part of the Soviet Salyut programme, and launched on 19 April 1982 on a Proton (rocket), Proton-K rocket from Baikonur Cosmodrome Site 200, Site 200/40 at the Baikonur Cosmodrome in the Soviet Union. Salyut 7 was part of the transition from monolithic to modular space stations, acting as a testbed for docking of additional modules and expanded station operations. It was the eighth space station of any kind launched. Salyut 7 was the last of both the second generation of DOS-series space stations and of the monolith ...
