Soyuz rockets are the longest-serving route to space. The design goes back to the Vostok launcher, which was used for the first manned spaceflight in 1961 to carry the Russian cosmonaut Yuri Gagarin.
A few Soyuz-FG Launcher characteristics
Diameter: 10.3 m
Height: 49.5 m
Total launch mass: 310 t
Launch performance payload: 7150 kg
Propellant mass: 157 t
In less than five minutes, the first two stages burn 225 000 kilograms of kerosene and liquid oxygen. When these have burned out, the third and last stage continues the upward trajectory.
Right at the top of the structure are the manned Soyuz capsule and the emergency rescue system.
When the last 22 tonnes of fuel have also been converted into forward thrust, the crew are eight minutes and forty seconds into their journey and are making a low-level orbit around the Earth. The Soyuz spacecraft separates and will continue to climb under its own power to an altitude of about four hundred kilometres, where it will dock with the International Space Station two days later.
