Vostok-L
The Vostok-L (russian: Восток meaning ''"East"''), GRAU index 8K72 was a rocket used by the Soviet Union to conduct several early tests of the Vostok spacecraft. It was derived from the Luna rocket, with a slightly enlarged second stage to accommodate the larger payload, and was a member of the Vostok family of rockets. It used the new 8K74 core instead of the 8K71 used on the original R-7 ICBM and the Luna boosters. The 8K74, first tested in December 1959, had a number of technical improvements to increase reliability and make servicing easier. Four launches were conducted between 15 May and 1 December 1960, three of which successfully reached orbit. The first flight, on 15 May 1960, carried the Korabl'-Sputnik 1 spacecraft. The second launched on 28 July, however one of the booster engines burned through at launch, causing the booster to separate prematurely, 19 seconds after launch. The rocket broke up 30 seconds after liftoff, killing the two dogs that were aboard the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 spac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korabl-Sputnik 3
Korabl-Sputnik 3 (russian: Корабль-Спутник 3 meaning ''Ship-Satellite 3'') or Vostok-1K No.3, also known as Sputnik 6 in the West, was a Soviet spacecraft which was launched in 1960. It was a test flight of the Vostok spacecraft, carrying two dogs; Pcholka and Mushka ("little bee" and "little fly"; affectionate diminutives of "pchela" and "mukha", respectively), as well as a television camera and scientific instruments. Korabl-Sputnik 3 was launched at 07:30:04 UTC on 1 December 1960, atop a Vostok-L carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome. It was successfully placed into low Earth orbit. The flight lasted one day, after which the spacecraft was deorbited ahead of its planned recovery. The deorbit burn began at 07:15 UTC on 2 December, however the engine did not cut off as planned at the end of the burn, and instead the spacecraft's fuel burned to depletion. This resulted in it reentering the atmosphere on a trajectory which might have permitte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vostok-K
The Vostok-K (russian: Восток 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 manned. It was derived from the earlier Vostok-L; however, it featured uprated engines to improve performance, and enlarge its payload capacity. 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 manned spaceflight, which made Yuri Gagarin the first human to fly in space. All six manned missions of the Vostok programme The Vostok programme (russian: Восток, , ''Orient'' or ''E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korabl-Sputnik 2
Korabl-Sputnik 2 (russian: Корабль-Спутник 2, lit=Ship-Satellite 2), also known as Sputnik 5 in the West, was a Soviet Union, Soviet artificial satellite, and the third test flight of the Vostok spacecraft. It was the first spaceflight to send animals into orbit and return them safely back to Earth, including two Soviet space dogs, Belka and Strelka. Launched on 19 August 1960, it paved the way for the first human orbital flight, Vostok 1, which was launched less than eight months later. Background Korabl-Sputnik 2 was the second attempt to launch a Vostok capsule with dogs on board. The first try on 28 July, carrying a pair named Bars (Snow Leopard aka Chaika (Seagull)) and Lisichka (Foxie), had been unsuccessful after the Blok G strap-on suffered a fire and breakdown in one of the combustion chambers, followed by its breaking off of the booster 19 seconds after launch. Around 30 seconds, the launch vehicle disintegrated, the core and strap-ons flying in random ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Korabl-Sputnik 1
Korabl-Sputnik 1 (russian: Корабль Спутник 1 meaning ''Vessel Satellite 1''), also known as Sputnik 4 in the West, was the first test flight of the Soviet Vostok programme, and the first Vostok spacecraft. It was launched on May 15, 1960. Though Korabl-Sputnik 1 was unmanned, it was a precursor to the first human spaceflight, Vostok 1. Its mass was , of which was instrumentation. The spacecraft, the first of a series of spacecraft used to investigate the means for manned space flight, contained scientific instruments, a television system, and a self-sustaining biological cabin with a dummy of a man. It was designed to study the operation of the life support system and the stresses of flight. The spacecraft radioed both extensive telemetry and prerecorded voice communications. After four days of flight, the retro rocket was fired and the descent module was separated from its equipment module, but because the spacecraft was not in the correct flight attitude when its ...

RD-0105
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, ...

R-7 (rocket Family)
The R-7 family of rockets (russian: Р-7) is a series of rockets, derived from the Soviet R-7 Semyorka, the world's first ICBM. More R-7 rockets have been launched than any other family of large rockets. When Soviet nuclear warheads became lighter, the R-7 turned out to be impractical as a ballistic missile, and there were no other heavy payloads with a military application. However, long-term development has made the rockets useful in the Soviet, and later, Russian space programmes. Their purpose shifted primarily to launching satellites, probes, manned and unmanned spacecraft, and other non-threatening payloads. The R-7 family consists of both missiles and orbital carrier rockets. Derivatives include the Vostok, Voskhod and Soyuz rockets, which as of 2022 have been used for all Soviet, and later Russian human spaceflights. The type has a unique configuration where four break-away liquid-fueled engines surround a central core. The core acts as, in effect, a "second stage" af ...

RD-107
The RD-107 and its sibling, the RD-108, are a type of rocket engine initially used to launch R-7 Semyorka missiles. RD-107 engines were later used on space launch vehicles based on the R-7. , very similar RD-107A and RD-108A engines are used to launch the Soyuz-2.1a, and Soyuz-2.1b, which are in active service. Design The RD-107 was designed under the direction of Valentin Glushko at the Experimental Design Bureau (OKB-456) between 1954 and 1957. It uses liquid oxygen and kerosene as propellants operating in a gas generator cycle. As was typical by all the descendants of the V-2 rocket technology, the turbine is driven by steam generated by catalytic decomposition of H₂O₂. The steam generator uses solid ''F-30-P-G'' catalyst. These are based on a variable sized pellet covered in an aqueous solution of potassium permanganate and sodium. Each engine uses four fixed main combustion chambers. The RD-107 has an additional two vernier combustion chambers that can thrust vecto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RP-1
RP-1 (alternatively, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel. RP-1 provides a lower specific impulse than liquid hydrogen (LH2), but is cheaper, is stable at room temperature, and presents a lower explosion hazard. RP-1 is far denser than LH2, giving it a higher energy density (though its specific energy is lower). RP-1 also has a fraction of the toxicity and carcinogenic hazards of hydrazine, another room-temperature liquid fuel. Usage and history RP-1 is a fuel in the first-stage boosters of the Electron, Soyuz, Zenit, Delta I-III, Atlas, Falcon, Antares, and Tronador II rockets. It also powered the first stages of the Energia, Titan I, Saturn I and IB, and Saturn V. The Indian Space Research Organization (ISRO) is also developing an RP-1 fueled engine for its future rockets.

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
