The Soyuz rocket is a Russian booster that has been in use since the 1960s. It is part of the R-7 rocket family, which was derived from the R-7 Semyorka, the world's first intercontinental ballistic missile. The Soyuz rocket has been used for both cargo and astronaut transportation, and it holds the record for the most launches in the history of spaceflight. Most variants of the rocket use RP-1 (a kerosene-based fuel) and liquid oxygen as propellant, although the Soyuz-U2 variant used liquid oxygen and Syntin, a variant of RP-1. The Soyuz rocket has been the world's most prolific launcher, flying hundreds of missions over 43 years until its retirement in 2017.

What You'll Learn
Soyuz rocket fuel type
The Soyuz rocket is a line of Russian boosters that have been used since the mid-1960s for both cargo and astronaut transportation. It is a part of the R-7 rocket family, which evolved from the R-7 Semyorka, the world's first intercontinental ballistic missile.
All variants of the Soyuz rocket use kerosene (RP-1) fuel and liquid oxygen (LOX), except for the Soyuz-U2, which used Syntin (a variant of RP-1) with LOX. RP-1 is a kerosene-based fuel.
Soyuz rockets are best known as the launch vehicles for crewed Soyuz spacecraft under the Soyuz programme, as well as for uncrewed Progress cargo spacecraft to the International Space Station (ISS). The majority of Soyuz launches have been dedicated to deploying satellites for both governmental and commercial purposes.
Soyuz rockets have had a long history of successful launches, with relatively few failures. It has become the world's most used space launcher, flying over 1700 times, far more than any other rocket. It is known for its low cost and high reliability.

Soyuz-U2 variant fuel
The Soyuz rocket family is a group of Soviet and later Russian medium-lift launch vehicles. The rockets are used for both cargo and astronaut transportation. The Soyuz rocket was the main form of transportation to the International Space Station between 2011 and 2020.
The Soyuz-U2 is a variant of the Soyuz-U rocket, which first flew in 1982. It has the same hardware as the basic Soyuz-U but uses a synthetic version of RP-1, called Syntin, as its first-stage fuel. This is combined with liquid oxygen (LOX) to create thrust. Syntin is a high-energy variant of RP-1, which is a kerosene-based fuel.
The increased performance of the Soyuz-U2 compared to the Soyuz-U was due to the use of Syntin. This allowed the Soyuz-U2 to carry heavier payloads and reach higher orbits. The Soyuz-U2 was mainly used to transport crew and cargo to the Mir space station.
The final flight of the Soyuz-U2 took place on 3 September 1995, from Gagarin's Start in Baikonur. The Soyuz-U2 was launched 72 times and experienced no failures over its operational lifetime. However, production of the rocket ended due to the high cost of Syntin production.

Soyuz rocket engine ignition
The Soyuz rocket is a Russian expendable medium-lift launch vehicle that has been used since the 1960s. It is a member of the R-7 rocket family, which was derived from the R-7 Semyorka, the world's first intercontinental ballistic missile. The rocket was initially designed by the OKB-1 design bureau and manufactured by the Progress Rocket Space Centre factory in Samara, Russia.
The Soyuz rocket uses RP-1 (a kerosene-based fuel) and liquid oxygen as propellant. The engines are ignited by electrically initiated pyrotechnic flares, which are mounted on birch poles and ignited approximately 20 seconds before fuel components are introduced into the combustion chamber. This sequence rarely fails due to its simplicity.
The Soyuz rocket has had a long history of successful launches, with some sources estimating that it has flown over 1,700 times, making it the world's most-used space launcher. It has been noted for its low cost and high reliability, with relatively few failures in hundreds of launches. However, there have been a handful of notable failures, including the human missions Soyuz 1 and Soyuz 11, which resulted in the deaths of four astronauts.
The Soyuz rocket has been used for both cargo and astronaut transportation to the International Space Station. Between 2011 and 2020, it was the main form of transportation to the ISS, and NASA purchased astronaut seats on Soyuz spacecraft during this period. The rocket has also been used to launch satellites for both governmental and commercial purposes.

Soyuz rocket launches
The Soyuz rocket is a Russian line of boosters that has been in use since the mid-1960s. It is used for both cargo and astronaut transportation. The rocket is known for its reliability, with a long history of successful launches. However, there have been a few notable failures, including the human missions Soyuz 1 and Soyuz 11, which resulted in the deaths of four astronauts.
Most variants of the Soyuz rocket use RP-1 (a kerosene-based fuel) and liquid oxygen as propellant. The exception is the Soyuz-U2, which used liquid oxygen and Syntin, a variant of RP-1. The height, payload capacity, and other characteristics of the Soyuz rocket depend on the variant being used. Russia does not readily share detailed information about the different variants, making comparisons between them challenging.
The Soyuz rocket has a unique launch system that eliminates the need for a launch pad. The engines are ignited by electrically initiated pyrotechnic flares mounted on birch poles a few seconds before the fuel components are introduced into the combustion chamber. This sequence rarely fails due to its simplicity. During launch, the support booms track the movement of the rocket.
Soyuz rockets are known for their simplicity and low cost. They have been used extensively for satellite launches for both governmental and commercial purposes. The Soyuz launcher reached a production peak of 60 per year in the early 1980s and has become the world's most-used space launcher, with over 1700 flights.
In summary, the Soyuz rocket is a reliable and versatile launch vehicle that has played a significant role in space exploration, particularly in the transportation of cargo and astronauts to the International Space Station. While it has experienced some failures, its overall success rate and longevity make it a notable achievement in spaceflight history.

Soyuz rocket cost
The Soyuz rocket is a family of Soviet and Russian medium-lift launch vehicles initially developed by the OKB-1 design bureau. It is manufactured by the Progress Rocket Space Centre factory in Samara, Russia. It is part of the R-7 rocket family, which evolved from the R-7 Semyorka, the world's first intercontinental ballistic missile. The rocket was introduced in 1966 and has since become the world's most used space launcher, flying over 1700 times, more than any other rocket.
The Soyuz rocket is known for its low cost and high reliability. However, the Russian space agency, Roscosmos, is not known for its transparency regarding costs. According to 2018 estimates, Roscosmos charges NASA and ESA (America and Europe's space agencies) just over $80 million (€70.7 million) per seat/astronaut. By comparison, the Falcon 9 costs $62 million per launch, and its larger sibling, the Falcon Heavy, costs a maximum of $90 million.
Soyuz rockets use kerosene (RP-1) fuel and liquid oxygen (LOX) as propellant. The exception is the Soyuz-U2, which uses Syntin (a variant of RP-1) with LOX. The fuel makes up most of the rocket's weight, which affects its maximum payload capacity.
The rocket has been used for both cargo and astronaut transportation to the International Space Station (ISS). From the final flight of the Space Shuttle program in 2011 until SpaceX's first crewed mission in 2020, Soyuz rockets were the only approved launch vehicles for transporting astronauts to the ISS.
