Goodyear Meteor Junior
The Goodyear Meteor Junior was a 1954 concept for a fully reusable spacecraft and launch system designed by Darrell C. Romick and two of his colleagues employed by Goodyear Aerospace, a subsidiary of the American Goodyear Tire and Rubber Company. Darrell Romick originally estimated that the craft would cost about the same as an intercontinental B-52 bomber. Concept The concept was introduced in 1954, before the dawn of human spaceflight, to be displayed at the annual conference of the American Rocket Society. The design called for a winged spacecraft piloted by a crew of three. The craft was to contain three stages, of which only the uppermost, containing the crew, would ultimately be propelled to orbit around Earth. Each of these three stages was to contain landing gear and a crew of its own, allowing the stages to be piloted to a landing to be reused in a future launch. For reentry and landing, the nose of each stage had a mechanism that would allow the nose to close into a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

Multistage Rocket
A multistage rocket or step rocket is a launch vehicle that uses two or more rocket ''stages'', each of which contains its own engines and propellant. A ''tandem'' or ''serial'' stage is mounted on top of another stage; a ''parallel'' stage is attached alongside another stage. The result is effectively two or more rockets stacked on top of or attached next to each other. Two-stage rockets are quite common, but rockets with as many as five separate stages have been successfully launched. By jettisoning stages when they run out of propellant, the mass of the remaining rocket is decreased. Each successive stage can also be optimized for its specific operating conditions, such as decreased atmospheric pressure at higher altitudes. This ''staging'' allows the thrust of the remaining stages to more easily accelerate the rocket to its final speed and height. In serial or tandem staging schemes, the first stage is at the bottom and is usually the largest, the second stage and subseq ...

1954 In Spaceflight
The year 1954 saw the conception of Project Orbiter, the first practicable satellite launching project, utilizing the Redstone, a newly developed Short Range Ballistic Missile. A variety of sounding rockets continued to return scientific data from beyond the boundary of space (as defined by the World Air Sports Federation), including the Viking and Aerobee rockets, University of Iowa and Naval Research Laboratory ship-launched rockoons, and derivatives of the Soviet R-1 missile. The French also launched their first sounding rocket into space, the Véronique-NA. 1954 also marked a year of development of the Intercontinental Ballistic Missile (ICBM). The United States prioritized the development of its Atlas while the Soviet Union authorized the draft proposal for the R-7 Semyorka, its first ICBM. Space exploration highlights US Navy After ten months of salvage, testing, and troubleshooting following the failed launch of Viking 10 on 30 June 1953, a successful static f ...

Downrange
Downrange, or down range, is the horizontal distance traveled by a spacecraft, or the spacecraft's horizontal distance from the launch site. More often, it is used as an adverb or adjective specifying the direction of that travel being measured in a horizontal direction. In military slang, ''downrange'' is a term for being deployed overseas, usually in a war zone. It is also the name of a comic strip published in the newspaper Stars and Stripes. It can also refer to the direction of fire: away from the source and in the direction of the target. In the 1960s and 1970s, a down range tracking system existed at Gulkula, in the Northern Territory of Australia, to track rockets launched from the Woomera Test Range in South Australia South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories ... ...

White Sands Missile Range
White Sands Missile Range (WSMR) is a United States Army military testing area and firing range located in the US state of New Mexico. The range was originally established as the White Sands Proving Ground on 9July 1945. White Sands National Park is located within the range. Significant events *The first atomic bomb (code named Trinity) was test detonated at Trinity Site near the northern boundary of the range on 16 July 1945, seven days after the White Sands Proving Ground was established. *After the conclusion of World War II, 100 long-range German V-2 rockets that were captured by U.S. military troops were brought to WSMR. Of these, 67 were test-fired between 1946 and 1951 from the White Sands V-2 Launching Site. (This was followed by the testing of American rockets, which continues to this day, along with testing other technologies.) *NASA's Space Shuttle Columbia landed on the Northrop Strip at WSMR on 30 March 1982 as the conclusion to mission STS-3.

Orbit
In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. For most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse-square law. However, Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics, provides a more accurate calculation and understanding of the exact mechanics of orbi ...

American Rocket Society
The American Rocket Society (ARS) began its existence on , under the name of the American Interplanetary Society. It was founded by science fiction writers G. Edward Pendray, David Lasser, Laurence Manning, Nathan Schachner, and others. Pendray corresponded with Willy Ley of the German rocket society, Verein für Raumschiffahrt, and visited him in 1931. The members originally conducted their own rocket experiments in New York and New Jersey. The society printed its own journal. The AIS did pioneering work in testing the design requirements of liquid-fueled rockets, with a number of successful test launches of ARS rockets occurring in this period and pointing the way to the United States space program. Its name was changed to American Rocket Society on . In 1936, the American Rocket Society and its member Alfred Africano were awarded the Prix d'Astronautique by the Société astronomique de France (French Astronomical Society) in recognition of their pioneering tests with liquid ...

Goodyear Aerospace
Goodyear Aerospace Corporation (GAC) was the aerospace and defense subsidiary of the Goodyear Tire and Rubber Company. The company was originally operated as a division within Goodyear as the Goodyear Zeppelin Corporation, part of a joint project with Luftschiffbau Zeppelin, leading to the development of rigid airships in the United States. As part of the failing relationship between the US and Germany in the era prior to World War II, the division was spun off as Goodyear Aircraft Company in 1939. The company opened a new factory in Arizona in 1941 which produced subassemblies, including subcontracted airframe construction and the design of the Goodyear F2G Corsair and Goodyear Duck. In the post-war era, the division began to diversify and made major contributions to the development of synthetic aperture radar. In 1963 they became Goodyear Aerospace, with major product lines in radar, aircraft canopies, bulletproof glass, a number of spacecraft related products, and the unique ...

Human Spaceflight
Human spaceflight (also referred to as manned spaceflight or crewed spaceflight) is spaceflight with a crew or passengers aboard a spacecraft, often with the spacecraft being operated directly by the onboard human crew. Spacecraft can also be remotely operated from ground stations on Earth, or autonomously, without any direct human involvement. People trained for spaceflight are called astronauts (American or other), ''cosmonauts'' (Russian), or ''taikonauts'' (Chinese); and non-professionals are referred to as spaceflight participants or ''spacefarers''. The first human in space was Soviet cosmonaut Yuri Gagarin, who launched as part of the Soviet Union's Vostok program on 12 April 1961 at the beginning of the Space Race. On 5 May 1961, Alan Shepard became the first American in space, as part of Project Mercury. Humans traveled to the Moon nine times between 1968 and 1972 as part of the United States' Apollo program, and have had a continuous presence in space for on the ...
