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 ...

Soyuz (rocket Family)
Soyuz (, GRAU index: 11A511) is a family of Soviet and later Russian expendable Medium-lift launch vehicle, medium-lift launch vehicles initially developed by the OKB-1 design bureau and manufactured by the Progress Rocket Space Centre factory in Samara, Russia. It holds the record for the most launches in the history of spaceflight. Soyuz rockets are part of the R-7 (rocket family), R-7 rocket family, which evolved from the R-7 Semyorka, the world's first intercontinental ballistic missile. As with many Soviet rockets, the names of recurring payloads became associated with the launch vehicle itself. Consequently, the Soyuz rockets are best known as the launch vehicles for crewed Soyuz (spacecraft), Soyuz spacecraft under the Soyuz programme, as well as for uncrewed Progress (spacecraft), Progress cargo spacecraft to the International Space Station (ISS). Despite this recognition, the majority of Soyuz launches have been dedicated to deploying satellites for both governmental a ...

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. It also ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Plesetsk Cosmodrome Site 41
Plesetsk Cosmodrome () is a Russian spaceport located in Mirny, Arkhangelsk Oblast, near the town of Plesetsk, from which it takes its name. Until 2025 and the commissioning of the Andøya base in Norway, it was the only operational orbital spaceport in Europe and the northernmost spaceport in the world. Originally developed as an intercontinental ballistic missile (ICBM) site for the R-7 missile, its strategic location approximately north of Moscow was key to its selection. Due to its high latitude, Plesetsk is particularly suited for specific types of satellite launches, such as those into Molniya orbits, and historically served as a secondary launch facility. Most Soviet orbital launches were conducted from Baikonur Cosmodrome, located in the Kazakh SSR. However, following the dissolution of the Soviet Union, Baikonur became part of Kazakhstan, which began charging Russia to lease the land for its use. As a result, Plesetsk has seen significantly increased activity sin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Progress Rocket Space Centre
Rocket and Space Centre "Progress" (), commonly known as RKTs Progress (), is a Russian joint-stock company under Roscosmos. It is responsible for building and operating the Soyuz (rocket family), Soyuz family of rockets, which serve as the primary launch vehicles for the Russian space program. The company traces its origins to the Soviet-era State Aviation Factory No. 1, established in Samara in 1941, which came to be known as "Progress." In 1974, the Central Specialized Design Bureau (TsSKB) was established to refine the R-7 rocket’s design. In 1996, these two entities merged to form the company TsSKB-Progress. History The company traces its origins to the Dux Factory, established in Moscow in 1894 as a small bicycle manufacturer. At the start of the 20th century, the Dux Factory transitioned from bicycles to producing cars and airships. By 1910, its focus shifted to aircraft manufacturing.

Soyuz T-10a
Soyuz 7K-ST No.16L, sometimes known as Soyuz T-10a or Soyuz T-10-1, was an unsuccessful Soyuz mission intended to visit the Salyut 7 space station, which was occupied by the Soyuz T-9 crew. However, it never finished its launch countdown; the launch vehicle was destroyed on the launch pad by fire on 26 September 1983. The launch escape system of the Soyuz spacecraft fired six seconds before the launch vehicle exploded, saving the crew. This is the only time a launch escape system has been fired before launch with a crew aboard. The Soyuz T-10-1 explosion would also remain the only instance of a Russian crewed booster accident in 35 years, until the Soyuz MS-10 flight aborted shortly after launch on 11 October 2018 due to a failure of the Soyuz-FG launch vehicle boosters. Crew Mission highlights The crew was sitting on the pad awaiting fueling of the Soyuz-U booster to complete prior to liftoff.
