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] |

RD-108
The RD-107 () and its sibling, the RD-108, are a type of rocket engine used on the R-7 rocket family. RD-107 engines are used in each booster and the RD-108 is used in the central core. The engines have four main combustion chambers (each with a nozzle) and either two (RD-107) or four (RD-108) vernier chambers. The engines were first developed in the mid-1950s to launch the R-7 Semyorka, the first intercontinental ballistic missile. The R-7 was later adapted into space launch vehicles and the engines have been improved over several generations. The most recent versions are the RD-107A and RD-108A engines are used to launch the Soyuz-2, which is 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 drive ...

Luna Programme
The Luna programme (from the Russian word "Moon, Luna" meaning "Moon"), occasionally called ''Lunik'' by western media, was a series of robotic spacecraft missions sent to the Moon by the Soviet Union between 1959 and 1976. The programme accomplished many Timeline of space exploration, firsts in space exploration, including Luna 1, first flyby of the Moon, Luna 2, first impact of the Moon and Luna 3, first photos of the far side of the Moon. Each mission was designed as either an orbiter or Lander (spacecraft), lander. They also performed many experiments, studying the Moon's chemical composition, gravity, temperature, and radiation. Twenty-four spacecraft were formally given the Luna designation, although more were launched. Those that failed to reach orbit were not publicly acknowledged at the time, and not assigned a Luna number. Those that failed in low Earth orbit were usually given Kosmos (satellite), Cosmos designations. The estimated cost of the Luna programme in 196 ...

Luna (rocket)
The Luna 8K72 vehicles were carrier rockets used by the Soviet Union for nine space probe launch attempts in the Luna programme between 23 September 1958 and 16 April 1960. Like many other Soviet launchers of that era, the Luna 8K72 vehicles were derived from the R-7 Semyorka design, part of the R-7 (rocket family), which was also the basis for the Vostok and modern Soyuz rocket. The 8K72 was the first R-7 variant explicitly designed as a carrier rocket and it incorporated a few features that became standard on all later R-7 carrier rockets including thicker tank walls to support the weight of upper stages and the AVD malfunction detection system, which would terminate engine thrust if the booster's operating parameters (engine performance, electrical power, or flight trajectory) deviated from normal. Launches Luna 8K72 was launched nine times from Baikonur LC-1/5: The first flight of a Luna 8K72 (September 1958), which was to launch the Luna E-1 No.1 probe, ended 92 second ...

Hydrogen Peroxide
Hydrogen peroxide is a chemical compound with the formula . In its pure form, it is a very pale blue liquid that is slightly more viscosity, viscous than Properties of water, water. It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use. Concentrated hydrogen peroxide, or "high-test peroxide", decomposes explosively when heated and has been used as both a monopropellant and an oxidizer in rocketry. Hydrogen peroxide is a reactive oxygen species and the simplest peroxide, a compound having an oxygen–oxygen single bond. It decomposes slowly into water and elemental oxygen when exposed to light, and rapidly in the presence of organic or reactive compounds. It is typically stored with a Stabilizer (chemistry), stabilizer in a weakly acidic solution in an opaque bottle. Hydrogen peroxide is found in biological systems including the human body.

1980 Plesetsk Launch Pad Disaster
The 1980 Plesetsk launch pad disaster was the explosion of a Vostok-2M rocket carrying a Tselina-D satellite during fueling at Site 43/4 of the Plesetsk Cosmodrome in the town of Mirny in the Soviet Union at 19:01 local time (16:01 UTC) on 18 March 1980, two hours and fifteen minutes before the intended launch time. Forty-four people were killed in the initial fire and four more soon died in the hospital from burns. It is the second deadliest space exploration-related disaster in history. Sequence of events On 17 March the rocket was installed at the launch site. Various preliminary tests conducted before the fueling went as expected and without problem. The Vostok-2M had been flying for 16 years with only a single in-flight failure and this vehicle, S/N 78055-330, would have been the 70th one launched. The launch of the rocket was scheduled to take place at 21:16 on 18 March. Several hours before the intended launch, the tanks were filled with RP-1 at 19:00 and preceded ...

Vostok (spacecraft)
Vostok (, 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 Cosmonautics Day, 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 (spacecraft), Voskhod. By the late 1960s, these were replaced with Soyuz (spacecraft), 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 spy satellite, Zenit) and as a crewed spacecraft. This dual-use design was crucial in gaining Communist Party of the Soviet Union, 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 uncr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sputnik 1
Sputnik 1 (, , ''Satellite 1''), sometimes referred to as simply Sputnik, was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's success was unanticipated by the United States. This precipitated the American Sputnik crisis and triggered the Space Race. The launch was the beginning of a new era of political, military, technological, and scientific developments. The word ''sputnik'' is Russian for ...

Vostok Programme
The Vostok programme ( ; rus, Восток, p=vɐˈstok, a=ru-восток.ogg, t=East) was a Soviet human spaceflight project to put the first Soviet cosmonauts into low Earth orbit and return them safely. Competing with the United States Project Mercury, it succeeded in placing the first human into space, Yuri Gagarin, in a single orbit in Vostok 1 on April 12, 1961. The Vostok capsule was developed from the Zenit spy satellite project, and its launch vehicle was adapted from the existing R-7 Semyorka intercontinental ballistic missile (ICBM) design. The name "Vostok" was treated as classified information until Gagarin's flight was first publicly disclosed to the world press. The programme carried out six crewed spaceflights between 1961 and 1963. The longest flight lasted nearly five days, and the last four were launched in pairs, one day apart. This exceeded Project Mercury's demonstrated capabilities of a longest flight of just over 34 hours, and of single missions. ...

Human Spaceflight
Human spaceflight (also referred to as manned spaceflight or crewed spaceflight) is spaceflight with a crew or passengers aboard a spacecraft, often with the spacecraft being operated directly by the onboard human crew. Spacecraft can also be telerobotic, remotely operated from ground stations on Earth, or Autonomous robot, autonomously, without any direct human involvement. People trained for spaceflight are called astronauts (American or other), ''cosmonauts'' (Russian), or ''taikonauts'' (Chinese); and non-professionals are referred to as spaceflight participants or ''spacefarers''. The first human in space was Soviet Union, Soviet cosmonaut Yuri Gagarin, who launched as part of the Soviet Union's Vostok program on Cosmonautics Day, 12 April 1961 at the beginning of the Space Race. On 5 May 1961, Alan Shepard became the first American in space, as part of Project Mercury. Humans traveled to the Moon nine times between 1968 and 1972 as part of the United States' Apollo progr ...
