On 4 October 1957, it was used to perform the world’s first satellite launch, placing Sputnik 1 into a low Earth orbit.Two versions of the Sputnik were built, the Sputnik-PS (GRAU index 8K71PS), which was used to launch Sputnik 1 and later Sputnik 2, and the Sputnik (8A91), which failed to launch a satellite in April 1958, and subsequently launched Sputnik 3 on 15 May 1958.[1]A later member of the R-7 family, the Polyot, used the same configuration as the Sputnik rocket, but was constructed from Voskhod components. Because of the similarity, the Polyot was sometimes known as the Sputnik 11A59.Table of ContentsSpecifications[edit]Sputnik 8A91[edit]Sputnik specifications[edit]References[edit]Specifications[edit]First Stage: Block B, V, G, D (four strap-on boosters)Gross mass: 43.0 tonsEmpty mass: 3.400 tonsThrust (vac): 4 \u00d7 99,000\u00a0kgf = 396\u00a0Mgf (3.89 MN)Isp: 306 s (3,000 N\u00b7s\/kg)Burn time: 120 s (2\u00a0min)Isp (sl): 250 s (2,450 N\u00b7s\/kg)Diameter: 2.68 metres (8.8\u00a0ft)Span: 2.68 metres (8.8\u00a0ft)Length: 19.2 metres (63\u00a0ft) (without nozzles)Propellants: LOX\/KeroseneEngines: 1 x RD-107-8D74PS per booster = 4Second Stage: Block A (core stage)Gross mass: 94.0 tonsEmpty mass: 7.495 tonsThrust (vac): 99,000\u00a0kgf (970\u00a0kN)Isp: 308 s (3,020 N\u00b7s\/kg)Burn time: 310 s (5\u00a0min 10 s)Isp(sl): 241 s (2,360 N\u00b7s\/kg)Diameter: 2.95 metres (9.7\u00a0ft)Span: 2.95 metres (9.7\u00a0ft)Length: 28 metres (92\u00a0ft)Propellants: LOX\/KeroseneEngine: 1 x RD-108-8D75PSTotal mass: 267 tons (534,000\u00a0lb)Total span: 10.303 metres (33.80\u00a0ft)LEO payload: 500\u00a0kgTotal liftoff thrust:  3.89 MN  Sputnik 8A91[edit]The Sputnik 8A91 had more powerful 8D76 and 8D77 engines installed,[2] increasing its payload capacity, and allowing it to launch much heavier satellites than Sputnik 1 and Sputnik 2. It was launched two times, in 1958.[3] The first launch, on 27 April, failed due to vibrations that unexpectedly occurred during the flight along the longitudinal axis of the rocket. On 15 May, it successfully launched Sputnik 3.[4][5]Sputnik specifications[edit]Stage number: 0 – Strap-on boosters; 4 x Sputnik 8A91-0Gross mass: 43.0 tonsEmpty mass: 3.400 tonsThrust (vac): 4 \u00d7 99,000\u00a0kgf = 396\u00a0Mgf (3.89 MN)Isp: 310 s (3,040 N\u00b7s\/kg)Burn time: 130 s (2\u00a0min 10 s)Isp(sl): 252 s (2,470 N\u00b7s\/kg)Diameter: 2.68 metres (8.8\u00a0ft)Span: 2.68 metres (8.8\u00a0ft)Length: 19.2 metres (63\u00a0ft) (without nozzles)Propellants: Lox\/KeroseneEngines: 1 x RD-107-8D76 per booster = 4Stage number: 1 – Core stage; 1 x Sputnik 8A91-1Gross mass: 95.0 tonsEmpty mass: 7.100 tonsThrust (vac): 82,000\u00a0kgf (804\u00a0kN)Isp: 315 s (3,090 N\u00b7s\/kg)Burn time: 360 s (6\u00a0min)Isp(sl): 246 s (2,410 N\u00b7s\/kg)Diameter: 2.95 metres (9.7\u00a0ft)Length:28 metres (92\u00a0ft)Propellants: LOX\/KeroseneEngine: 1 x RD-108-8D77Total mass: 269.3 tons[vague]Total span: 10.303 metres (33.80\u00a0ft)LEO payload: 1,327\u00a0kg (2,925\u00a0lb)Total liftoff thrust:  385,950\u00a0kgf (3.784 MN, 850,870 lbf)References[edit]"},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki43\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki43\/sputnik-rocket-wikipedia\/#breadcrumbitem","name":"Sputnik (rocket) – Wikipedia"}}]}]
