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] |
Sputnik (rocket)
The Sputnik rocket was an uncrewed orbital carrier rocket designed by Sergei Korolev in the Soviet Union, derived from the R-7 Semyorka ICBM. On 4 October 1957, it was used to perform the world's first satellite launch, placing ''Sputnik 1'' into a low Earth orbit. Two versions of the Sputnik were built, the Sputnik-PS ( GRAU index 8K71PS), which was used to launch ''Sputnik 1'' and later ''Sputnik 2'', and the Sputnik (8A91), which failed to launch a satellite in April 1958, and subsequently launched '' Sputnik 3'' on 15 May 1958. A later member of the R-7 family, the Polyot, used the same configuration as the Sputnik rocket, but was constructed from Voskhod components. Because of the similarity, the Polyot was sometimes known as the Sputnik 11A59. Specifications *First Stage: Block B, V, G, D (four strap-on boosters) **Gross mass: 43.0 tons **Empty mass: 3.400 tons **Thrust (vac): 4 × 99,000 kgf = 396 Mgf (3.89 MN) ** Isp: 306 s (3,000 N·s/kg) **Burn time: ...

Small-lift Launch Vehicle
A small-lift launch vehicle is a rocket orbital launch vehicle that is capable of lifting or less (by NASA classification) or under (by Roscosmos classification) of payload into low Earth orbit (LEO). The next larger category is medium-lift launch vehicles. The first small-lift launch vehicle was the Sputnik rocket, launched by the Soviet Union, which was derived from the R-7 Semyorka ICBM. On 4 October 1957, the Sputnik rocket was used to perform the world's first satellite launch, placing the Sputnik 1 satellite into a low Earth orbit. The US responded by attempting to launch the Vanguard rocket. However, the Vanguard TV3 launch attempt failed, with the 31 January 1958 launch of the Explorer 1 satellite using the Juno I rocket being the first successful US orbital launch. The Vanguard I mission was the second successful US orbital launch. This was the start of the space race. Since the late 1950s, small-lift launch vehicles have continued launching payloads into orbits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which are small CubeSats. Similar satellites can work together as groups, forming constellatio ...

Operation Paperclip
The Operation Paperclip was a secret United States intelligence program in which more than 1,600 German scientists, engineers, and technicians were taken from former Nazi Germany to the US for government employment after the end of World War II in Europe, between 1945 and 1959; several were confirmed to be former members of the Nazi Party, including the SS or the Sturmabteilung, SA. The effort began in earnest in 1945, as the Allies advanced into Germany and discovered a wealth of scientific talent and advanced research that had contributed to Germany's wartime technological advancements. The US Joint Chiefs of Staff officially established Operation Overcast (operations "Overcast" and "Paperclip" were related, and the terms are often used interchangeably) on July 20, 1945, with the dual aims of leveraging German expertise for the ongoing war effort against Japan and to bolster US postwar military research. The operation, conducted by the Joint Intelligence Objectives Agency (JI ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnus Von Braun
Magnus "Mac" Freiherr von Braun (10 May 1919 – 21 June 2003) was a German chemical engineer, Luftwaffe aviator, rocket scientist and business executive. In his 20s, he worked on Nazi Germany’s guided missile development and production at the Peenemünde Army Research Center and the Mittelwerk from 1943-1945. At age 26, he emigrated to the United States via Operation Paperclip, where he worked for some years at Fort Bliss. In 1955 he began a new career as a senior executive with Chrysler's missile division, later moving to automotive products. He retired to Arizona in 1975, where he died in 2003. He was the younger brother of Sigismund von Braun, Sigismund and Wernher von Braun.
