Voskhod (rocket)
The Voskhod rocket (russian: Восход, ''"ascent"'', ''"dawn"'') was a derivative of the Soviet R-7 ICBM designed for the human spaceflight programme but later used for launching Zenit reconnaissance satellites. It consisted of the Molniya 8K78M third stage minus the Blok L. In 1966, all R-7 variants were equipped with the uprated core stage and strap-ons of the Soyuz 11A511. The Blok I stage in the Voskhod booster used the RD-0107 engine rather than the crew rated and more powerful RD-0110 used on the Soyuz. The sole exception to this were the two manned Voskhod launches, which had RD-0108 engines, a crew-rated RD-0107 but with the same performance. All 11A57s launched after 1965 were functionally a 11A511 without the Soyuz's payload shroud and launch escape system (with the exception of the second stage propulsion system as noted above). Around 300 were flown from Baikonur and Plesetsk through 1976 (various payloads, but Zenith IMINT satellites were the most common). ...

Human-rating Certification
Human-rating certification, also known as man-rating or crew-rating, is the certification of a spacecraft or launch vehicle as capable of safely transporting humans. There is no one particular standard for human-rating a spacecraft or launch vehicle, and the various entities that launch or plan to launch such spacecraft specify requirements for their particular systems to be human-rated. NASA One entity that applies human rating is the US government civilian space agency, NASA. NASA's human-rating requires not just that a system be designed to be tolerant of failure and to protect the crew even if an unrecoverable failure occurs, but also that astronauts aboard a human-rated spacecraft have some control over it. This set of technical requirements and the associated certification process for crewed space systems are in addition to the standards and requirements for all of NASA's space flight programs. The development of the Space Shuttle and the International Space Station pre-da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ICBM
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Imagery Intelligence
Imagery intelligence (IMINT), pronounced as either as ''Im-Int'' or ''I-Mint'', is an intelligence gathering discipline wherein imagery is analyzed (or "exploited") to identify information of intelligence value. Imagery used for defense intelligence purposes is generally collected via satellite imagery or aerial photography. As an intelligence gathering discipline, IMINT production depends heavily upon a robust intelligence collection management system. IMINT is complemented by non-imaging MASINT electro-optical and radar sensors. History Origins Although aerial photography was first used extensively in the First World War, it was only in the Second World War that specialized imagery intelligence operations were initiated. High quality images were made possible with a series of innovations in the decade leading up to the war. In 1928, the RAF developed an electric heating system for the aerial camera. This allowed reconnaissance aircraft to take pictures from very high alt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch Escape System
A launch escape system (LES) or launch abort system (LAS) is a crew-safety system connected to a space capsule that can be used to quickly separate the capsule from its launch vehicle in case of an emergency requiring the abort of the launch, such as an impending explosion. The LES is typically controlled by a combination of automatic rocket failure detection, and a manual activation for the crew commander's use. The LES may be used while the launch vehicle is still on the launch pad, or during its ascent. Such systems are usually of two types: *A solid-fueled rocket, mounted above the capsule on a tower, which delivers a relatively large thrust for a brief period of time to send the capsule a safe distance away from the launch vehicle, at which point the capsule's parachute recovery system can be used for a safe landing on ground or water. The tower and rocket are jettisoned from the space vehicle in a normal flight at the point where it is either no longer needed, or cannot be e ...

Payload Shroud
A payload fairing is a nose cone used to protect a spacecraft payload against the impact of dynamic pressure and aerodynamic heating during launch through an atmosphere. An additional function on some flights is to maintain the cleanroom environment for precision instruments. Once outside the atmosphere the fairing is jettisoned, exposing the payload to outer space. The standard payload fairing is typically a cone-cylinder combination, due to aerodynamic considerations, although other specialized fairings are in use. The type of fairing which separates into two halves upon jettisoning is called a clamshell fairing by way of analogy to the bifurcating shell of a clam. In some cases the fairing may enclose both the payload and the upper stage of the rocket, such as on Atlas V and Proton M. If the payload is attached both to the booster's core structures and to the fairing, the payload may still be affected by the fairing's bending loads, as well as inertia loads due to vibrations ...

RD-0110
The RD-0110 (or RO-8 , RD-0108 , RD-461 ) is a rocket engine burning liquid oxygen and kerosene in a gas generator combustion cycle. It has four fixed nozzles and the output of the gas generator is directed to four secondary vernier nozzles to supply vector control of the stage. It has an extensive flight history with its initial versions having flown more than 57 years ago (as of February 2018). History OKB-154 of S.A. Kosberg was tasked with developing an engine for the unmanned Molniya Block-I stage. Thus, the RD-0107 was developed in the 1960 to 1961 period, based on the RD-0106 (GRAU Index: 8D715) engine that powered the SS-8 Sasin ICBM, also designed by OKB-154. It also leveraged the experience in the field from the Vostok Block-E RD-0105/RD-0109 development. The engine had its debut flight on October 10, 1960, and the last Molniya flight was on October 22, 1967. For the crewed carrying Voskhod Block-I, a version of the engine that complied with the human rating 3K Reg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
11A511
Soyuz (russian: Союз, meaning "union", GRAU index 11A511) is a family of expendable Russian and Soviet carrier rockets developed by OKB-1 and manufactured by Progress Rocket Space Centre in Samara, Russia. With over 1,900 flights since its debut in 1966, the Soyuz is the most frequently used launch vehicle in the world as of 2021. For nearly a decade, between the final flight of the Space Shuttle program in 2011 and the 2020 first crewed mission of SpaceX's Falcon 9 rocket, Soyuz rockets were the only launch vehicles able and approved for transporting astronauts to the International Space Station. The Soyuz vehicles are used as the launcher for the crewed Soyuz spacecraft as part of the Soyuz programme, as well as to launch uncrewed Progress supply spacecraft to the International Space Station and for commercial launches marketed and operated by Starsem and Arianespace. All Soyuz rockets use RP-1 and liquid oxygen (LOX) propellant, with the exception of the Soyuz-U2, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
