Mary Sherman Morgan
Mary Sherman Morgan (November 4, 1921 – August 4, 2004) was a U.S. rocket fuel scientist credited with the invention of the liquid fuel Hydyne in 1957, which powered the Jupiter-C rocket that boosted the United States' first satellite, Explorer 1. Early life and education The second youngest of six siblings, Mary Sherman was born to Michael and Dorothy Sherman on their farm in Ray, North Dakota. She grew up in a family of bullying siblings and indifferent parents who kept her out of school to work on the farm. Social services stepped in and threatened to arrest Mary's father unless he allowed her to attend school. The social worker then provided her with riding lessons and a horse to attend her one-roomed school house. In 1939, she graduated as her high school's valedictorian. She then enrolled at DeSales College in Toledo, Ohio as a chemistry major. Career During Sherman's college education, the Second World War broke out. As a result of men going overseas to fight, the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bagel
A bagel ( yi, בײגל, translit=beygl; pl, bajgiel; also spelled beigel) is a bread roll originating in the History of Jews in Poland, Jewish communities of Poland. It is traditionally shaped by hand into a roughly hand-sized ring from yeasted wheat dough that is first Boiling in cooking, boiled for a short time in water and then Baking, baked. The result is a dense, chewy, doughy interior with a browned and sometimes crisp exterior. Bagels are often topped with seeds baked on the outer crust—traditional choices include poppy and sesame seeds—or with salt grains. Different dough types include whole-grain and rye. The basic roll-with-a-hole design, hundreds of years old, allows even cooking and baking of the dough; it also allows groups of bagels to be gathered on a string or dowel for handling, transportation, and retail display. The earliest known mention of a boiled-then-baked ring-shaped bread can be found in a 13th-century Syrian cookbook, where they are referred to ...

Juno I
The Juno I was a four-stage American space launch vehicle, used to launch lightweight payloads into low Earth orbit. The launch vehicle was used between January 1958 to December 1959. The launch vehicle was a member of the Redstone launch vehicle family, and was derived from the Jupiter-C sounding rocket. It is commonly confused with the Juno II launch vehicle, which was derived from the PGM-19 Jupiter medium-range ballistic missile. In 1958, a Juno I launch vehicle was used to launch America's first satellite, Explorer 1. History Developed as a part of the Explorer Project, the original goal for the launch vehicle was to place an artificial satellite into orbit. Following the Soviet Union's launch of Sputnik 1 on October 4, 1957 (and the resulting "Sputnik crisis") and the failure of the Vanguard 1 launch attempt, the program received funding to match the Soviet space achievements. The launch vehicle family name was proposed in November 1957 by Jet Propulsion Lab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanguard (rocket)
The Vanguard rocket was intended to be the first launch vehicle the United States would use to place a satellite into orbit. Instead, the Sputnik crisis caused by the surprise launch of Sputnik 1 led the U.S., after the failure of Vanguard TV-3, to quickly orbit the Explorer 1 satellite using a Juno I rocket, making Vanguard 1 the second successful U.S. orbital launch. Vanguard rockets were used by Project Vanguard from 1957 to 1959. Of the eleven Vanguard rockets which the project attempted to launch, three successfully placed satellites into orbit. Vanguard rockets were an important part of the Space Race between the United States and the Soviet Union. Overview In 1955, the United States announced plans to put a scientific satellite in orbit for the International Geophysical Year (IGY) in 1957–1958. The goal was to track the satellite as it performed experiments. At that time, there were three candidates for the launch vehicle: The Air Force's SM-65 Atlas, a derivative of the ...

Sputnik 1
Sputnik 1 (; see § Etymology) 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 ran out, and continued in orbit for three months until 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 unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments. The word ''sputnik'' is Russian for ''satellite ...

International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific interchange between East and West had been seriously interrupted. Sixty-seven countries participated in IGY projects, although one notable exception was the mainland People's Republic of China, which was protesting against the participation of the Republic of China ( Taiwan). East and West agreed to nominate the Belgian Marcel Nicolet as secretary general of the associated international organization. The IGY encompassed eleven Earth sciences: aurora and airglow, cosmic rays, geomagnetism, gravity, ionospheric physics, longitude and latitude determinations (precision mapping), meteorology, oceanography, seismology, and solar activity. The timing of the IGY was particularly suited for studying some of these phenomena, since it cove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diethylenetriamine
Diethylenetriamine (abbreviated and also known as 2,2’-Iminodi(ethylamine)) is an organic compound with the formula HN(CH2CH2NH2)2. This colourless hygroscopic liquid is soluble in water and polar organic solvents, but not simple hydrocarbons. Diethylenetriamine is structural analogue of diethylene glycol. Its chemical properties resemble those for ethylene diamine, and it has similar uses. It is a weak base and its aqueous solution is alkaline. DETA is a byproduct of the production of ethylenediamine from ethylene dichloride. Reactions and uses Diethylenetriamine is a common curing agent for epoxy resins in epoxy adhesives and other thermosets. It is N-alkylated upon reaction with epoxide groups forming crosslinks. In coordination chemistry, it serves as a tridentate ligand forming complexes such as Co(dien)(NO2)3. Like some related amines, it is used in oil industry for the extraction of acid gas.

Jupiter C
The Jupiter-C was an American research and development vehicle developed from the Jupiter-A. Jupiter-C was used for three unmanned sub-orbital spaceflights in 1956 and 1957 to test re-entry nosecones that were later to be deployed on the more advanced PGM-19 Jupiter mobile missile. The recovered nosecone was displayed in the Oval Office as part of President Dwight D. Eisenhower's televised speech on November 7, 1957. A member of the Redstone rocket family, Jupiter-C was designed by the U.S. Army Ballistic Missile Agency (ABMA), under the direction of Wernher von Braun. Three Jupiter-C flights were made followed by three satellite launches ( Juno I). All were launched from Cape Canaveral, Florida. Description Each vehicle consisted of a modified Redstone ballistic missile with two solid-propellant upper stages. The tanks of the Redstone were lengthened by 8 ft (2.4 m) to provide additional propellant. The instrument compartment was also smaller and lighter than the ...

Redstone (rocket)
The PGM-11 Redstone was the first large American ballistic missile. A short-range ballistic missile (SRBM), it was in active service with the United States Army in West Germany from June 1958 to June 1964 as part of NATO's Cold War defense of Western Europe. It was the first US missile to carry a live nuclear warhead, in the 1958 Pacific Ocean weapons test, Hardtack Teak. The Redstone was a direct descendant of the German V-2 rocket, developed primarily by a team of German rocket engineers brought to the United States after World War II. The design used an upgraded engine from Rocketdyne that allowed the missile to carry the W39 warhead which weighed with its reentry vehicle to a range of about . Redstone's prime contractor was the Chrysler Corporation. The Redstone spawned the Redstone rocket family which holds a number of firsts in the US space program, notably launching the first US astronaut. It was retired by the Army in 1964 and replaced by the solid-fueled MGM-31 P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
