1952 In Spaceflight
In 1952, several branches of the United States' military, often in partnership with civilian organizations, continued their programs of sounding rocket research beyond the boundary of space (as defined by the World Air Sports Federation) using the Aerobee rocket. The University of Iowa launched its first series of rockoon flights, demonstrating the validity of the balloon-launched rocket, a comparatively inexpensive way to explore the upper atmosphere. The launch of Viking 9 at the end of the year to an altitude of , by the Naval Research Laboratory team under the management of Milton Rosen, represented the pinnacle of contemporary operational rocket design. The same year, groundwork was laid for the launch of the first artificial satellite when, in October, the General Assembly of the International Council of Scientific Unions (ICSU) scheduled the International Geophysical Year for 1957–58. This scientific endeavor would involve 67 nations in a global investigation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are powered only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles (SRBM) typically stay within the Earth's atmosphere, while most larger missiles travel outside the atmosphere. The type of ballistic missile with the greatest range is an intercontinental ballistic missile (ICBM). The largest ICBMs are capable of full orbital flight. These missiles are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight and thus restricted to the atmosphere. History One modern pioneer ballistic missile was the A-4, commonly known as the V-2, developed by Nazi Germany in the 1930s and 1940s under the direction of Wernher von Braun. The first successful launch of a V-2 was on October 3, 1942, and it began operation on September 6, 1944, against Paris, followed by an attack on London two ...

Aeronomy
Aeronomy is the scientific study of the upper atmosphere of the Earth and corresponding regions of the atmospheres of other planets. It is a branch of both atmospheric chemistry and atmospheric physics. Scientists specializing in aeronomy, known as aeronomers, study the motions and chemical composition and properties of the Earth's upper atmosphere and regions of the atmospheres of other planets that correspond to it, as well as the interaction between upper atmospheres and the space environment. In atmospheric regions aeronomers study, chemical dissociation and ionization are important phenomena. History The mathematician Sydney Chapman introduced the term ''aeronomy'' to describe the study of the Earth's upper atmosphere in 1946 in a letter to the editor of ''Nature'' entitled "Some Thoughts on Nomenclature." The term became official in 1954 when the International Union of Geodesy and Geophysics adopted it. "Aeronomy" later also began to refer to the study of the correspond ...

Emulsion
An emulsion is a mixture of two or more liquids that are normally Miscibility, immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms ''colloid'' and ''emulsion'' are sometimes used interchangeably, ''emulsion'' should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed phase (matter), phase) is dispersion (chemistry), dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, homogenized milk, liquid biomolecular condensates, and some cutting fluids for metal working. Two liquids can form different types of emulsions. As an example, oil and water can form, first, an oil-in-water emulsion, in which the oil is the dispersed phase, and water is the continuous phase. Second, they can form a water-in-oil emulsion, in which water is the dispersed phase and oil is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-ray
An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays. Roughly, X-rays have a wavelength ranging from 10 Nanometre, nanometers to 10 Picometre, picometers, corresponding to frequency, frequencies in the range of 30 Hertz, petahertz to 30 Hertz, exahertz ( to ) and photon energies in the range of 100 electronvolt, eV to 100 keV, respectively. X-rays were discovered in 1895 in science, 1895 by the German scientist Wilhelm Röntgen, Wilhelm Conrad Röntgen, who named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . X-rays can penetrate many solid substances such as construction materials and living tissue, so X-ray radiography is widely used in medical diagnostics (e.g., checking for Bo ...

Ultraviolet
Ultraviolet radiation, also known as simply UV, is electromagnetic radiation of wavelengths of 10–400 nanometers, shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs, Cherenkov radiation, and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. The photons of ultraviolet have greater energy than those of visible light, from about 3.1 to 12 electron volts, around the minimum energy required to ionize atoms. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack sufficient energy, it can induce chemical reactions and cause many substances to glow or fluoresce. Many practical applications, including chemical and biological effects, are derived from the way that UV radiation can interact with organic molecules. The ...

Cosmic Ray
Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk are deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have ...

Fuselage
The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as well, although in some amphibious aircraft the single engine is mounted on a hardpoint, pylon attached to the fuselage, which in turn is used as a floating Hull (watercraft), hull. The fuselage also serves to position the Flight control surfaces, control and Stabilizer (aeronautics), stabilization surfaces in specific relationships to Wing, lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welding, welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight strin ...

R-2 (missile)
The R-2 (NATO reporting name SS-2 Sibling) was a Soviet short-range ballistic missile developed from and having twice the range as the R-1 missile (itself a copy of the German V-2). Developed from 1946-1951, the R-2 entered service in numbers in 1953 and was deployed in mobile units throughout the Soviet Union until 1962. A sounding rocket derivative, the R-2A, tested a prototype of the dog-carrying capsule flown on Sputnik 2 in 1957. The same year, the R-2 was licensed for production in the People's Republic of China, where it entered service as the Dongfeng 1. History In 1945 the Soviets captured several key A-4 ( V-2) rocket production facilities, and also gained the services of some German scientists and engineers related to the project. Under the supervision of the Special technical Commission (OTK) established by the Soviet Union to oversee rocketry operations in Germany, A-4s were assembled and studied. This prompted the 13 May 1946 decree of the Soviet Council of Min ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
R-1 (missile)
The R-1 rocket (NATO reporting name SS-1 Scunner, Soviet code name SA11, GRAU index 8A11) was a tactical ballistic missile, the first manufactured in the Soviet Union, and closely based on the German V-2 rocket. The R-1 missile system entered into service in the Soviet Army on 28 November 1950. Deployed largely against NATO, it was never an effective strategic weapon. Nevertheless, production and launching of the R-1 gave the Soviets valuable experience which later enabled the USSR to construct its own much more capable rockets. History In 1945 the Soviets captured several key A-4 ( V-2) rocket production facilities, and also gained the services of some German scientists and engineers related to the project. In particular the Soviets gained control of the main V-2 manufacturing facility at Nordhausen. Under the supervision of the Special technical Commission (OTK) established by the Soviet Union to oversee rocketry operations in Germany, A-4s were assembled and studied. This p ...
