Künzelsau
Künzelsau (; East Franconian: ''Kinzelse'') is a town in Baden-Württemberg, in south central Germany. It is the capital of the Hohenlohe district. It is located on the river Kocher, 19 km (12 mi) north of Schwäbisch Hall, and 37 km (23 mi) northeast of Heilbronn. Geography The city of Künzelsau is located, at elevation , along the Kocher River, a right tributary of the Neckar River, some 40 km east (25 mi) of Heilbronn. The city is, after Öhringen, the second largest city of the Hohenlohe district, whose seat it is. The Hohenlohe district was created on 1 January 1973 by merging the former districts of Künzelsau (KÜN) and Öhringen (ÖHR). The city of Künzelsau thus retained being the district seat, so that the license plate number still uses KÜN.

Wernher Von Braun
Wernher Magnus Maximilian Freiherr von Braun ( , ; 23 March 191216 June 1977) was a German and American aerospace engineer and space architect. He was a member of the Nazi Party and Allgemeine SS, as well as the leading figure in the development of rocket technology in Nazi Germany and later a pioneer of rocket and space technology in the United States. As a young man, von Braun worked in Nazi Germany's rocket development program. He helped design and co-developed the V-2 rocket at Peenemünde during World War II. Following the war, he was secretly moved to the United States, along with about 1,600 other German scientists, engineers, and technicians, as part of Operation Paperclip. He worked for the United States Army on an intermediate-range ballistic missile program, and he developed the rockets that launched the United States' first space satellite Explorer 1 in 1958. He worked with Walt Disney on a series of films, which popularized the idea of human space travel in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saturn V
Saturn V is a retired American super heavy-lift launch vehicle developed by NASA under the Apollo program for human exploration of the Moon. The rocket was human-rated, with multistage rocket, three stages, and powered with liquid-propellant rocket, liquid fuel. It was flown from 1967 to 1973. It was used for nine crewed flights to the Moon, and to launch Skylab, the first American space station. the Saturn V remains the only launch vehicle to carry humans beyond low Earth orbit (LEO). Saturn V holds records for the heaviest payload launched and largest payload capacity to low Earth orbit: , which included the third stage and unburned propellant needed to send the Apollo command and service module and Apollo Lunar Module, Lunar Module to the Moon. The largest production model of the Saturn (rocket family), Saturn family of rockets, the Saturn V was designed under the direction of Wernher von Braun at the Marshall Space Flight Center in Huntsville, Alabama; the lead contractor ...

United States Nationality Law
United States nationality law details the conditions in which a person holds United States nationality. In the United States, nationality is typically obtained through provisions in the U.S. constitution, U.S. Constitution, various laws, and international agreements. Citizenship is a right, not a privilege. While the domestic documents often use citizenship and nationality interchangeably, nationality refers to the legal means in which a person obtains a national identity and formal membership in a nation and citizenship refers to the relationship held by nationals who are also citizens. Individuals born in any of the 50 U.S. states, the District of Columbia or almost any inhabited Territories of the United States, territory are Natural-born-citizen clause, natural-born United States citizens. The sole exception is American Samoa, where individuals are typically non-citizen U.S. nationals at birth. Foreign nationals living in any state or qualified territory may naturalize aft ...

Naturalization
Naturalization (or naturalisation) is the legal act or process by which a non-citizen of a country may acquire citizenship or nationality of that country. It may be done automatically by a statute, i.e., without any effort on the part of the individual, or it may involve an application or a motion and approval by legal authorities. The rules of naturalization vary from country to country but typically include a promise to obey and uphold that country's laws and taking and subscribing to an oath of allegiance, and may specify other requirements such as a minimum legal residency and adequate knowledge of the national dominant language or culture. To counter multiple citizenship, some countries require that applicants for naturalization renounce any other citizenship that they currently hold, but whether this renunciation actually causes loss of original citizenship, as seen by the host country and by the original country, will depend on the laws of the countries involved.

Operation Paperclip
Operation Paperclip was a secret United States intelligence program in which more than 1,600 German scientists, engineers, and technicians were taken from the former Nazi Germany to the U.S. for government employment after the end of World War II in Europe, between 1945 and 1959. Conducted by the Joint Intelligence Objectives Agency (JIOA), it was largely carried out by special agents of the U.S. Army's Counterintelligence Corps (CIC). Many of these personnel were former members and some were former leaders of the Nazi Party. In February 1945, Supreme Headquarters Allied Expeditionary Force (SHAEF) set up T-Force, or Special Sections Subdivision, which grew to over 2,000 personnel by June. T-Force examined 5,000 German targets with a high priority on synthetic rubber and oil catalysts, new designs in armored equipment, V-2 (rocket) weapons, jet and rocket propelled aircraft, naval equipment, field radios, secret writing chemicals, aero medicine research, gliders, and "scientif ...

Ernst Steinhoff
Ernst August Wilhelm Steinhoff (February 11, 1908 – December 2, 1987) was a rocket scientist and member of the " von Braun rocket group", at the Peenemünde Army Research Center (1939–1945). Ernst Steinhoff saw National Socialist (Nazi) doctrines as "ideals" and became a member of the NSDAP in May 1937. He was a glider pilot, holding distance records, and had the honorary Luftwaffe rank of "Flight Captain". Ernst Steinhoff earned his PhD at the Technische Hochschule Darmstadt (today Technische Universität Darmstadt) in 1940 with a dissertation on aviation instruments. His younger brother Friedrich Steinhoff assisted rocket experiments while commanding in 1942. Ernst was among the scientists to surrender and travel to the United States to provide rocketry expertise via Operation Paperclip. Friedrich was captured aboard and committed suicide in a Boston jail before Ernst came to the United States on the first boat, November 16, 1945. with Operation Paperclip and Fort ...

Rocket Engine
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, reducing the e ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
