Exoatmospheric Reentry-vehicle Interceptor Subsystem
The Exoatmospheric Reentry-vehicle Interceptor Subsystem, or ERIS, program, was a component of the United States' Strategic Defense Initiative during the Cold War. The ERIS system was named after Eris, Greek goddess of strife. ERIS was a kinetic kill system, launched from a ground-based system, and impacting directly to destroy an incoming Intercontinental ballistic missile (ICBM) before the targeted ICBM re-entered the Earth's atmosphere. Background The 1972 Anti-Ballistic Missile Treaty between the U.S. and the Soviet Union permitted each nation to have two ABM sites, each limited to 100 missiles, for a total of 200 ABMs per nation. A 1976 Protocol added to the ABM treaty further limited each nation to a single, 100 missile site. Development In 1985, Lockheed Corporation was awarded a contract to develop an ABM system - the ERIS - that was compliant with the ABM Treaty. ERIS was to be a high altitude component of SDI that would operate in outer space. It would intercept ...

Exoatmospheric Reentry-vehicle Interception System Rocket
The exosphere ( grc, ἔξω "outside, external, beyond", grc, σφαῖρα "sphere") is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collisionless. In the case of bodies with substantial atmospheres, such as Earth's atmosphere, the exosphere is the uppermost layer, where the atmosphere thins out and merges with outer space. It is located directly above the thermosphere. Very little is known about it due to lack of research. Mercury, the Moon, Ceres, Europa, and Ganymede have surface boundary exospheres, which are exospheres without a denser atmosphere underneath. The Earth's exosphere is mostly hydrogen and helium, with some heavier atoms and molecules near the base. Surface boundary exosphere Mercury, Ceres and several large natural satellites, such as the Moon, Europa, and Ganymede, have exospheres without a denser atmo ...

Minuteman I
The LGM-30 Minuteman is an American land-based intercontinental ballistic missile (ICBM) in service with the Air Force Global Strike Command. , the LGM-30G Minuteman III version is the only land-based ICBM in service in the United States and represents the land leg of the U.S. nuclear triad, along with the Trident submarine-launched ballistic missile (SLBM) and nuclear weapons carried by long-range strategic bombers. Development of the Minuteman began in the mid-1950s when basic research indicated that a solid-fuel rocket motor could stand ready to launch for long periods of time, in contrast to liquid-fueled rockets that required fueling before launch and so might be destroyed in a surprise attack. The missile was named for the colonial minutemen of the American Revolutionary War, who could be ready to fight on short notice. The Minuteman entered service in 1962 as a deterrence weapon that could hit Soviet cities with a second strike and countervalue counterattack if the U.S. ...

Terminal High Altitude Area Defense
Terminal High Altitude Area Defense (THAAD), formerly Theater High Altitude Area Defense, is an American anti-ballistic missile defense system designed to shoot down short-, medium-, and intermediate-range ballistic missiles in their terminal phase (descent or reentry) by intercepting with a hit-to-kill approach. THAAD was developed after the experience of Iraq's Scud missile attacks during the Gulf War in 1991. The THAAD interceptor carries no warhead, instead relying on its kinetic energy of impact to destroy the incoming missile. Originally a United States Army program, THAAD has come under the umbrella of the Missile Defense Agency. The Navy has a similar program, the sea-based Aegis Ballistic Missile Defense System, which also has a land component ("Aegis Ashore"). THAAD was originally scheduled for deployment in 2012, but initial deployment took place in May 2008. THAAD has been deployed in the United Arab Emirates, Israel, Romania, and South Korea.

Aries (rocket)
Aries is an American sounding rocket and target rocket, developed by Space Vector Corporation from retired LGM-30 Minuteman I intercontinental ballistic missile (ICBM) stages for use by the United States Air Force and NASA. Taken over by Orbital Sciences Corporation, Aries, as the Target Test Vehicle, remains in use. Design and development In the late 1960s, the retirement of the LGM-30 Minuteman I ICBM resulted in the opportunity to produce a high-performance sounding rocket from the surplus solid-propellant rockets that became available; the Naval Research Laboratory awarded a contract to Space Vector Corporation in 1971Parsch 2005 to develop the "Fat Albert" rocket using the surplus Minuteman I first stages; before the first launch, the name of the rocket was changed to the "more dignified" Aries.Dickson 2009, pp. 24–25. Aries consisted of an Aerojet M56 solid-fuel rocket, the second stage of the Minuteman I, fitted with an aerodynamic nose cone and four tail fins, taken ...

Lockheed Corporation
The Lockheed Corporation was an American aerospace manufacturer. Lockheed was founded in 1926 and later merged with Martin Marietta to form Lockheed Martin in 1995. Its founder, Allan Lockheed, had earlier founded the similarly named but otherwise-unrelated Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. History Origins Allan Loughead and his brother Malcolm Loughead had operated an earlier aircraft company, Loughead Aircraft Manufacturing Company, which was operational from 1912 to 1920. The company built and operated aircraft for paying passengers on sightseeing tours in California and had developed a prototype for the civil market, but folded in 1920 due to the flood of surplus aircraft deflating the market after World War I. Allan went into the real estate market while Malcolm had meanwhile formed a successful company marketing brake systems for automobiles.

White Sands Missile Range Museum-98 (8326903749)
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...
