Vostok (spacecraft)
Vostok (russian: Восток, translated as "East") was a class of single-pilot crewed spacecraft built by the Soviet Union. The first human spaceflight was accomplished with Vostok 1 on April 12, 1961, by Soviet cosmonaut Yuri Gagarin. The Vostok programme made six crewed spaceflights from 1961 through 1963. This was followed in 1964 and 1965 by two flights of Vostok spacecraft modified for up to three pilots, identified as Voskhod. By the late 1960s, these were replaced with Soyuz spacecraft, which are still used . Development The Vostok spacecraft was originally designed for use both as a camera platform (for the Soviet Union's first spy satellite program, Zenit) and as a crewed spacecraft. This dual-use design was crucial in gaining Communist Party support for the program. The basic Vostok design has remained in use for some 40 years, gradually adapted for a range of other uncrewed satellites. The descent module design was reused, in heavily modified form, by the Voskhod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

G-force
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, ''g'', of about . Since g-forces indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of each object's mass. The types of forces involved are transmitted through objects by interior mechanical stresses. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The g-force experienced by an object is due to the vector sum of all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project Mercury
Project Mercury was the first human spaceflight program of the United States, running from 1958 through 1963. An early highlight of the Space Race, its goal was to put a man into Earth orbit and return him safely, ideally before the Soviet Union. Taken over from the US Air Force by the newly created civilian space agency NASA, it conducted 20 uncrewed developmental flights (some using animals), and six successful flights by astronauts. The program, which took its name from Roman mythology, cost $ (adjusted for inflation). The astronauts were collectively known as the "Mercury Seven", and each spacecraft was given a name ending with a "7" by its pilot. The Space Race began with the 1957 launch of the Soviet satellite Sputnik 1. This came as a shock to the American public, and led to the creation of NASA to expedite existing US space exploration efforts, and place most of them under civilian control. After the successful launch of the Explorer 1 satellite in 1958, crewed spacef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tonka (fuel)
Tonka (also TONKA-250 and R-Stoff) is the name given to a German-designed rocket propellant first used in the Wasserfall missile, and recently used by North Korea. It was used in the Soviet Union under the name TG-02, for example in the engine designs of the A.M. Isayev Chemical Engineering Design Bureau. Its name is a reference to the tonka bean. Being invented during the Second World War, it has no connection to the similarly named toys. Its composition is approximately 50% triethylamine and 50% xylidine, most commonly used with nitric acid or its anhydrous nitric oxide derivatives (classified as the AK-2x family in the Soviet Union) as the oxidiser; the combination is hypergolic and has a maximum practical specific impulse of approximately at sea level, with the latter figure stated as a specification for the R-21 Submarine Launched Ballistic Missile, first fielded in 1963. The Soviet Union reverse-engineered the Wasserfall missile and investigated the use of hypergolic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Valentina Tereshkova
Valentina Vladimirovna Tereshkova ( rus, Валентина Владимировна Терешкова, links=no, p=vɐlʲɪnʲˈtʲinə vlɐˈdʲimʲɪrəvnə tʲɪrʲɪʂˈkovə, a=Valentina Tereshkova.ogg; born 6 March 1937) is an engineer, member of the Russian State Duma, and former Soviet cosmonaut. She is known for being the first and youngest woman in space, having flown a solo mission on the Vostok 6 on 16 June 1963. She orbited the Earth 48 times, spent almost three days in space, and remains the only woman to have been on a solo space mission. Before her selection for the Soviet space program, Tereshkova was a textile factory worker and an amateur skydiver. She joined the Air Force as part of the Cosmonaut Corps and was commissioned as an officer after completing her training. After the dissolution of the first group of female cosmonauts in 1969, Tereshkova remained in the space program as a cosmonaut instructor. She later graduated from the Zhukovsky Air Force E ...

Vostok 6
Vostok 6 (russian: Восток-6, ''Orient 6'' or ''East 6'') was the first human spaceflight to carry a woman, cosmonaut Valentina Tereshkova, into space. Mission The spacecraft was launched on 16 June 1963. While Vostok 5 had been delayed by technical problems, Vostok 6's launch proceeded with no difficulties. Data collected during the mission provided better understanding of the female body's reaction to spaceflight. Like other cosmonauts on Vostok missions, Tereshkova maintained a flight log, took photographs, and manually oriented the spacecraft. Her photographs of the horizon from space were later used to identify aerosol layers within the atmosphere. The mission, a joint flight with Vostok 5, was originally conceived as being a joint mission with two Vostoks each carrying a female cosmonaut, but this changed as the Vostok program experienced cutbacks as a precursor to the retooling of the program into the Voskhod program. Vostok 6 was the last flight of a Vostok 3KA spacecr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vostok 8K72K
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] |
Baikonur Cosmodrome
The Baikonur Cosmodrome ( kk, Байқоңыр ғарыш айлағы, translit=Baiqoñyr ğaryş ailağy, ; russian: Космодром Байконур, translit=Kosmodrom Baykonur, ) is a spaceport in an area of southern Kazakhstan leased to Russia.

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] |
Biconic
Many shapes have metaphorical names, i.e., their names are metaphors: these shapes are named after a most common object that has it. For example, "U-shape" is a shape that resembles the letter U, a bell-shaped curve has the shape of the vertical cross-section of a bell, etc. These terms may variously refer to objects, their cross sections or projections. Types of shapes Some of these names are "classical terms", i.e., words of Latin or Ancient Greek etymology. Others are English language constructs (although the base words may have non-English etymology). In some disciplines, where shapes of subjects in question are a very important consideration, the shape naming may be quite elaborate, see, e.g., the taxonomy of shapes of plant leaves in botany. * Astroid * Aquiline, shaped like an eagle's beak (as in a Roman nose) * Bell-shaped curve * Biconic shape, a shape in a way opposite to the hourglass: it is based on two oppositely oriented cones or truncated cones with their ba ...
