University Of Tennessee Space Institute
The University of Tennessee Space Institute (UTSI) is a satellite campus of the University of Tennessee located near Tullahoma, Tennessee. UTSI was founded to allow students to take advantage of the aerospace facilities located in the Arnold Engineering Development Center on Arnold Air Force Base, including wind tunnels and other laboratory equipment. Currently, the research activities conducted at UTSI are largely through the Mechanical, Aerospace, and Biomedical Engineering department. History UTSI was founded in the aftermath of World War II and in the midst of the Cold War. The seeds that ultimately led to UTSI began in the 1930s. German aeronautical superiority resulted in German fielding of the first jet propelled aircraft and ballistic missiles, thus proving the need for research facilities devoted to the study of aeronautics and related sciences. Had the German manufacturing capability been equivalent to that of the United States, the outcome of World War II wou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Per Aspera Ad Astra
is a Latin language, Latin phrase meaning "to the stars". The phrase has origins with Virgil, who wrote in his ''Aeneid'': "''sic itur ad astra''" ('thus one journeys to the stars') and "''opta ardua pennis astra sequi''" ('desire to pursue the high[/hard to reach] stars on wings'). Another origin is Seneca the Younger, who wrote in ''Hercules (Seneca), Hercules'': "" ('there is no easy way from the earth to the stars'). Etymology ''Ad'' is a Latin preposition expressing direction toward in space or time (e.g. ''ad nauseam'', ''ad infinitum'', ''ad hoc'', ''Ad libitum, ad libidem'', ''Ad valorem tax, ad valorem'', ''ad hominem''). It is also used as a prefix in Latin word formation. ''Astra'' is the Accusative case, accusative plural form of the Latin word ''astrum'' 'star' (from Ancient Greek ἄστρον ''astron'' 'star', from Proto-Indo-European language, Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂stḗr, ''*h₂ster-''). Mottos is used as, or as p ... [...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 ...

National Aeronautics And Space Administration
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the United States's civil space program, aeronautics research and space research. Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the American space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo program missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program and oversees the development of the Orion spacecraft and the Space Launch System for the lunar Artemis program. NASA's science division is focused on better understanding Earth through the Earth Observing System; advancing heliophysics through the effor ...

Sputnik
Sputnik 1 (, , ''Satellite 1''), sometimes referred to as simply Sputnik, was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's success was unanticipated by the United States. This precipitated the American Sputnik crisis and triggered the Space Race. The launch was the beginning of a new era of political, military, technological, and scientific developments. The word ''sputnik'' is Russian for ...

Caltech
The California Institute of Technology (branded as Caltech) is a private university, private research university in Pasadena, California, United States. The university is responsible for many modern scientific advancements and is among a small group of Institute of Technology (United States), institutes of technology in the United States that are devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery Hale, Arthur Amos Noyes, and Robert Andrews Millikan in the early 20th century. The vocational and preparatory schools were disbanded and spun off in 1910, and the college assumed its present name in 1920. In 1934, Caltech was elected to the Association of American Universities, and the antecedents of NASA's Jet Propulsion Laboratory, which Caltech continues to manage and operate, were established between 1936 and 1943 under ...

NACA
The National Advisory Committee for Aeronautics (NACA) was a United States federal agency that was founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research. On October 1, 1958, the agency was dissolved and its assets and personnel were transferred to the newly created National Aeronautics and Space Administration (NASA). NACA is an initialism, pronounced as individual letters rather than as a whole word, as was NASA during the early years after being established. Among other advancements, NACA research and development produced the NACA duct, a type of air intake used in modern automotive applications, the NACA cowling, and several series of NACA airfoils, which are still used in aircraft manufacturing. During World War II, NACA was described as "The Force Behind Our Air Supremacy" due to its key role in producing working superchargers for high altitude bombers, and for producing the laminar wing profiles for the North American P-51 Mustan ...

Jimmy Doolittle
James Harold Doolittle (December 14, 1896 – September 27, 1993) was an American military general and aviation pioneer who received the Medal of Honor for his raid on Japan during World War II, known as the Doolittle Raid in his honor. He made early coast-to-coast flights and record-breaking speed flights, won many flying races, and helped develop and flight-test instrument flying. According to the US FAA, he was the first pilot ever to perform a successful instrument flight. Doolittle grew up in Nome, Alaska. He attended the University of California, Berkeley, where he graduated with a Bachelor of Arts in 1922. That year, he made the first cross-country flight in an Airco DH.4, and in 1925, was awarded a doctorate in aeronautics from the Massachusetts Institute of Technology, the first such doctorate degree issued in the United States. In 1927, he performed the first outside loop, thought at the time to be a fatal aerobatic maneuver, and two years later, in 1929, pioneere ...

Propulsion
Propulsion is the generation of force by any combination of pushing or pulling to modify the translational motion of an object, which is typically a rigid body (or an articulated rigid body) but may also concern a fluid. The term is derived from two Latin words: ''wikt:pro, pro'', meaning'' before'' or ''forward''; and ''wikt:pellere, pellere'', meaning ''to drive''. A propulsion system consists of a source of mechanical power, and a ''propulsor'' (means of converting this power into propulsive force). Plucking a guitar string to induce a vibration, vibratory translation is technically a form of propulsion of the guitar string; this is not commonly depicted in this vocabulary, even though human muscles are considered to propel the fingertips. The motion of an object moving through a gravitational field is affected by the field, and within some frames of reference physicists speak of the gravitational field generating a force upon the object, but for general relativity, deep the ...
