Vostok-2 (rocket)
The Vostok-2 ( meaning ''"East"''), GRAU index 8A92 was an expendable carrier rocket used by the Soviet Union between 1962 and 1967. Forty five were launched, of which five failed. It was derived from the earlier Vostok-K, with uprated engines. It was a member of the Vostok family of rockets. The Vostok-2 switched to the newer 8K74 core and featured the 8D74K first stage engines from the Molniya 8K78 booster which gave it improved performance over the older Vostok 8K72K. The Vostok-2 made its maiden flight on 1 June 1962, from Site 1/5 at the Baikonur Cosmodrome. One of the booster engines shut down 1.8 seconds after launch, and the rocket came down away from the pad. The resulting explosion damaged the launch complex, and necessitated delays to several other launches that had been scheduled from that complex, including Vostok 3 and Vostok 4. Thirteen months later, on 10 July 1963, an almost identical failure occurred. The other three failures were caused by a second stage malf ...

RD-0109
The RD-0109 is a rocket engine burning liquid oxygen and kerosene in a gas generator combustion cycle. It has single nozzle and is an evolution of the RD-0105. It was the engine used on the Vostok Block-E that launched Yuri Gagarin to orbit. Development After the success of Sputnik 1, Korolev sent series of letters to the Central Committee of the Communist Party of the Soviet Union proposing a bold plan to send robotic spacecraft to Mars and Venus. As part of such plan, a fourth stage was needed to enhance the three stage R-7 rocket and enable it to send useful payloads to those high energy destinations. This fourth stage was called Block-E, and its development started during 1958. Korolev's OKB-1 design bureau initially competed two projects for the Block-E propulsion: 8K72, using the S.A. Kosberg's OKB-154 RD-0105, and the 8K73, using Glushko's OKB-456 RD-109 engine. Due to the complication of developing that latter, Kosberg got the contract. Since the February 20, 19 ...

Voskhod (rocket)
The Voskhod rocket (, ''"ascent"'', ''"dawn"'') was a derivative of the Soviet Union, Soviet R-7 Semyorka, R-7 ICBM designed for the human spaceflight Voskhod programme, programme but later used for launching Zenit (satellite), Zenit reconnaissance satellites. It was essentially an 8K78/8K78M minus the Blok L stage and spec-wise was a halfway between the two boosters, with the former's older, lower-spec engines and the latter's improved Blok I design. Its first flight was on 16 November 1963 when it successfully launched a Zenit satellite from LC-1/5 at Baikonur. Boosters used in the Voskhod program had a man-rated version of the RD-0107 engine; this version was known as the RD-0108. Starting in 1966, the 11A57 adopted the standardized 11A511 core with the more powerful 8D74M first stage engines, however the Blok I stage continued using the RD-0107 engine rather than the RD-0110. Around 300 were flown from Baikonur and Plesetsk through 1976, almost all of them used to launch Ze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reconnaissance Satellite
A reconnaissance satellite or intelligence satellite (commonly, although unofficially, referred to as a spy satellite) is an Earth observation satellite or communications satellite deployed for military or intelligence applications. The first generation type (i.e., Corona and Zenit) took photographs, then ejected canisters of photographic film which would descend back down into Earth's atmosphere. Corona capsules were retrieved in mid-air as they floated down on parachutes. Later, spacecraft had digital imaging systems and downloaded the images via encrypted radio links. In the United States, most information available about reconnaissance satellites is on programs that existed up to 1972, as this information has been declassified due to its age. Some information about programs before that time is still classified information, and a small amount of information is available on subsequent missions. A few up-to-date reconnaissance satellite images have been declassifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vostok 4
Vostok 3 () and Vostok 4 (, 'Orient 4' or 'East 4') were Soviet space program flights in August 1962, intended to determine the Effect of spaceflight on the human body, ability of the human body to function in conditions of weightlessness, test the ground control capability to launch and manage two separate, concurrent flights, and test the endurance of the Vostok 3KA spacecraft over longer flights. Cosmonaut Andriyan Nikolayev orbited the Earth 64 times in Vostok 3 over nearly four days in space, August 11–15, 1962, a feat which would not be matched by NASA until the Gemini program (1965–1966). Pavel Popovich was launched on Vostok 4 on August 12, and made 48 Earth orbits. The two capsules were launched on trajectories that brought the spacecraft within approximately of each another. They also communicated with each other via radio, the first ship-to-ship communications in space. These missions marked the first time that more than one crewed spacecraft was in orbit at the ...

Vostok (rocket Family)
Vostok (Russian: Восток, translated as "East") was a family of rockets derived from the Soviet R-7 Semyorka ICBM and was designed for the human spaceflight programme. This family of rockets launched the first artificial satellite (Sputnik 1) and the first crewed spacecraft ( Vostok) in human history. It was a subset of the R-7 family of rockets. On March 18, 1980, a Vostok-2M rocket exploded on its launch pad at Plesetsk during a fueling operation, killing 48 people. An investigation into a similarbut avoidedaccident revealed that the substitution of lead-based for tin-based solder in hydrogen peroxide filters allowed the breakdown of the H2O2, thus causing the resultant explosion. Variants The major versions of the rocket were: * Luna 8K72 – used to launch the early Luna spacecraft * Vostok-L 8K72 – Variant of the Luna, used to launch prototype Vostok spacecraft * Vostok-K 8K72K – a refined version of the above. This was the version actually used for human spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vostok-K
The Vostok-K ( meaning ''"East"''), GRAU index 8K72K was an expendable carrier rocket used by the Soviet Union for thirteen launches between 1960 and 1964, six of which were crewed. It incorporated several modifications to the core and strap-ons to man-rate them and the Blok E stage also had the improved RD-0109 engine to correct some deficiences in the RD-0105 used on earlier 8K78s. It was a member of the Vostok family of rockets. The Vostok-K made its maiden flight on 22 December 1960, three weeks after the retirement of the Vostok-L. The third stage engine failed 425 seconds after launch, and the payload, a Korabl-Sputnik spacecraft, failed to reach orbit. The spacecraft was recovered after landing, and the two dogs aboard the spacecraft survived the flight. On 12 April 1961, a Vostok-K rocket was used to launch Vostok 1, the first human spaceflight, making Yuri Gagarin the first human to fly in space. All six crewed missions of the Vostok programme The Vostok progra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Launch Vehicle
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload (a crewed spacecraft or satellites) from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles use chemical prope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expendable Launch System
An expendable launch system (or expendable launch vehicle/ELV) is a launch vehicle that can be launched only once, after which its components are destroyed during reentry or impact with Earth, or discarded in space. ELVs typically consist of several rocket stages that are discarded sequentially as their fuel is exhausted and the vehicle gains altitude and speed. As of 2024, fewer and fewer satellites and human spacecraft are launched on ELVs in favor of reusable launch vehicles. However, there are many instances where a ELV may still have a compelling use case over a reusable vehicle. ELVs are simpler in design than reusable launch systems and therefore may have a lower production cost. Furthermore, an ELV can use its entire fuel supply to accelerate its payload, offering greater payloads. ELVs are a proven technology in widespread use for many decades. Current operators Arianespace China ISRO During the 1960s and 1970s, India initiated its own launch vehicle program ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GRAU Index
The Main Missile and Artillery Directorate of the Ministry of Defense of the Russian Federation (), commonly referred to by its transliterated acronym GRAU (), is a department of the Russian Ministry of Defense. It is subordinate to the Chief of Armament and Munition of the Russian Armed Forces, a vice-minister of defense. The organization dates back to 1862 when it was established under the name Main Artillery Directorate (, GAU). The "R" from "rockets" was added to the title from 19 November 1960. The GRAU is responsible for assigning GRAU indices to Russian army ammunitions and equipment. As of April 2025, the Chief of the GRAU was Major General Aleksey Volkov. Arsenals Arsenals of the GRAU, according to Kommersant-Vlast in 2005, included the 53rd at Dzerzhinsk, Nizhniy Novogorod Oblast, the 55th in the Sklad-40 microraion at Rzhev, the 60th at Kaluga, the 63rd at Lipetsk, the 75th at Serpukhov south of Moscow, and the 97th at Skolin (all five in the Moscow Military Di ...
