Leonov served as a consultant for the design process, which was completed during 1966. Suit fabrication and testing occurred in 1967, but the Soyuz 1 accident in April of that year and Soyuz docking difficulties on the Soyuz 2 and Soyuz 3 missions delayed their use in space until the Soyuz 4 and Soyuz 5 flights. To prevent the suit from ...
'Union‑2.1c', [a] GRAU index: 14A15) [3] known early in development as the Soyuz‑1, was a expendable Russian small-lift launch vehicle. It is derivative of the Soyuz‑2 but utilizing a single core stage (no boosters) built around the powerful NK-33 engine, 50-year-old refurbished remnants from the Soviet N1 moon rocket.
In the mid-2010s, Soyuz-7 was initially conceived to be a scalable family, with three conceptual versions: Basic version, designed to replace the Soyuz-2.1a/b rockets, was to have used just a first and a second stage. It was conceived to have a payload to a 200 km (120 mi) circular LEO orbit of 9 t (8.9 long tons; 9.9 short tons). [16] [9]
As of 2024, both pads remain in use for the Soyuz-2.1a and Soyuz-2.1b rockets. Additionally, Site 43/4 also hosts launches of the smaller Soyuz-2.1v launch vehicle.

[note 2] Liquid-propellant rockets have a motor that feeds liquid propellant(s) into a combustion chamber. Most liquid engines use a bipropellant , consisting of two liquid propellants (fuel and oxidizer) which are stored and handled separately before being mixed and burned inside the combustion chamber.
The first era of the Soyuz programme's crewed missions (Soyuz 1-40) used the 7K series of Soyuz craft, which included the first-generation (1.0) Soyuz 7K-OK, a variant (1.5) Soyuz 7K-OKS, the second-generation (2.0) Soyuz 7K-T, and the (2.5) Soyuz 7K-TM variant. Following this first era, successive eras of crewed missions have had mission ...
