The third stage architecture of a Soyuz rocket also helps greatly to prevent any of these problems from happening. Note the truss architecture at the top of the stage for the Russian launcher and the skirt architecture on the American launcher (Credits: NPO Energomash, NASA). With a so called ‘parallel’ architecture, meaning that the stages are next to each other instead of staged on top of one another, most of these problems are avoided.Īn example of two massive first stages: the Russian N1 Block-A (left) and the American Saturn V S1-C (right). Last but not least, you must make sure that the nozzle of your second stage does not hit the bottom stage upper skirt. You must also make sure that the bottom stage does not have any residual thrust, for it might collide with the second stage after separation. This separation is a complex transient phase as you must do it quickly: every second lost at this point can be a net loss in the overall performance. This avoids the complex process of shutting down the lower stage engines properly before releasing the second stage and igniting its engine. After leaving the lower layers of the atmosphere, less thrust is needed to keep the launcher in flight and the strap-on boosters are jettisoned with the core stage still in operation. At this point, most of the thrust is provided by the strap-on boosters. The launcher is then released only after startup of all engines is confirmed. The smooth operation of the engines is tested during thrust ramp up while the rocket is still attached to the launch pad. The central stage and the strap-on booster engines of a Soyuz rocket are all ignited on the ground. This design is quite uncommon in the launcher industry but is a simple solution to two problems of the early days that remain two of the main challenges of space flight today: igniting an engine in space and separating the stages. On top of this core stage there is another smaller liquid stage separated by an open truss structure. The common architecture to all variants of the R-7 rocket is a core booster stage surrounded by strap-on boosters. Soyuz, and more generally all R-7 rockets, use exclusively rocket engines burning liquid propellants. These boosters are jettisoned prior to the main stage engine cut off during flight but provide most of the thrust at lift-off. (Credits : Arianespace/CNES). But the latest addition to the Soyuz family is the quite secretive Soyuz 2-1v launcher, which made its maiden flight last December.Īn example of mating of the core stage and strap-on boosters of the Soyuz rocket in Kourou, French Guiana. Several configurations of this launcher exist, one of which is even launched from the tropics by Arianespace as a commercial launcher. The latest family from the R-7 dynasty is the well-known “Soyuz” launcher which is named after the Soyuz spacecraft used by the Russians for manned spaceflight.

The R-7 series has become one of the most reliable and most versatile launcher family in the world, almost a fourth of all satellites sent into space worldwide have been launched by an R-7 derivative. Since that day, all cosmonauts and astronauts departing from Kazakhstan have launched onboard one of the many descendants of this rocket. 1 and make history aboard another R-7 derivative. A few anxious minutes later, the first manmade satellite started to emit its famous “bips.”Ī few years and a few changes to the rocket and launch pad later, it was time for Yuri Gagarin to start his journey from Launch Site No.

After a series of failures in the short missile development program, the rocket with the serial number 8K71-8 had been selected to bring Object D, later renamed Sputnik, into orbit. On it sat a modified intercontinental ballistic missile nicknamed “small seven,” only a few seconds away from lift-off. At this crucial moment in history, Launch Site No.1 of the soviet base of Baikonur in what is now Kazakhstan was calm. Not many can imagine what the thoughts of Sergei Korolev were on October 5 th 1957 at 1:28 am, Baikonur Time.

Meet the latest arrival in this long series: the Soyuz 2-1v which made its maiden flight last December 29th, as a late Christmas present. While you might think that this venerable rocket is outdated, it is still the workhorse of the Russian space industry, and the only means of access for astronauts to the International Space Station. It has since launched payloads for all ranges of space applications. It sent Sputnik, the first manmade satellite, into space in 1957 and made mankind a spacefaring race only a few years later. The R-7 « Semyorka » (small seven) might be one of the most iconic rockets of all time, scoring above a staggering 1600 launches over five decades.
