Mercury-Atlas 6
Mercury-Atlas 6 (MA-6) was the first crewed American orbital spaceflight, which took place on February 20, 1962. Piloted by astronaut John Glenn and operated by NASA as part of Project Mercury, it was the fifth human spaceflight, preceded by Soviet orbital flights Vostok 1 and 2 and American sub-orbital flights Mercury-Redstone 3 and 4. The Mercury spacecraft, named ''Friendship 7'', was carried to orbit by an Atlas LV-3B launch vehicle lifting off from Launch Complex 14 at Cape Canaveral, Florida. After three orbits, the spacecraft re-entered the Earth's atmosphere, splashed down in the North Atlantic Ocean, and was safely taken aboard . The total mission flight time was 4 hours 55 minutes and 23 seconds. Preparation After the successful completion of the Mercury-Atlas 5 flight that carried Enos, a chimpanzee, in late November 1961, a press conference was held in early December. Reporters asked NASA's Robert Gilruth who would be the first U.S. astronaut in orbit, pilo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Glenn
John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016) was an American Marine Corps aviator, astronaut, businessman, and politician. He was the third American in space and the first to orbit the Earth, circling it three times in 1962. Following his retirement from NASA, he served from 1974 to 1999 as a United States Senate, U.S. Senator from Ohio; in 1998, he flew into space again at the age of 77. Before joining NASA, Glenn was a distinguished fighter pilot in World War II, the Operation Beleaguer, Chinese Civil War, and the Korean War. He shot down three MiG-15s and was awarded six Distinguished Flying Cross (United States), Distinguished Flying Crosses and eighteen Air Medals. In 1957, he made the first supersonic transcontinental flight across the United States. His on-board camera took the first continuous, panoramic photograph of the United States. Glenn was one of the Mercury Seven military test pilots selected in 1959 by NASA as the nation's first astron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sub-orbital Spaceflight
A sub-orbital spaceflight is a spaceflight in which the spacecraft reaches outer space, but its trajectory intersects the surface of the primary (astronomy), gravitating body from which it was launched. Hence, it will not complete one orbital revolution, will not become an artificial satellite nor will it reach escape velocity. For example, the path of an object launched from Earth that reaches the Kármán line (about – above sea level), and then falls back to Earth, is considered a sub-orbital spaceflight. Some sub-orbital flights have been undertaken to test spacecraft and launch vehicles later intended for orbital spaceflight. Other vehicles are specifically designed only for sub-orbital flight; examples include crewed vehicles, such as the North American X-15, X-15 and SpaceShipTwo, and uncrewed ones, such as intercontinental ballistic missile, ICBMs and sounding rockets. Flights which attain sufficient velocity to go into low Earth orbit, and then de-orbit before com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benzylamine
Benzylamine, also known as phenylmethylamine, is an Organic chemistry, organic chemical compound with the Structural formula#Condensed formulas, condensed structural formula C6H5CH2NH2 (sometimes abbreviated as Phenyl group#Nomenclature, PhCH2NH2 or Benzyl#Abbreviations, BnNH2). It consists of a benzyl group, C6H5CH2, attached to an amine functional group, NH2. This colorless water-soluble liquid is a common precursor in organic chemistry and used in the industrial production of many pharmaceuticals. The hydrochloride salt was used to treat motion sickness on the Mercury-Atlas 6 mission in which NASA astronaut John Glenn became the first American to orbit the Earth. Manufacturing Benzylamine can be produced by several methods, the main industrial route being the reaction of benzyl chloride and ammonia. It is also produced by the reduction of benzonitrile and reductive amination of benzaldehyde, both done over Raney nickel. : It was first produced accidentally by Rudolf Leucka ...

Mephentermine Sulfate
Mephentermine, sold under the brand name Wyamine among others, is a sympathomimetic medication which was previously used in the treatment of low blood pressure but is mostly no longer marketed. It is used by injection into a vein or muscle, by inhalation, and by mouth. Side effects of mephentermine include dry mouth, sedation, reflex bradycardia, arrhythmias, and hypertension. Mephentermine induces the release of norepinephrine and dopamine and is described as an indirectly acting sympathomimetic and psychostimulant. Its sympathomimetic effects are mediated by indirect activation of α- and β-adrenergic receptors. Chemically, it is a substituted phenethylamine and amphetamine and is closely related to phentermine and methamphetamine. Mephentermine was first described and introduced for medical use by 1952. It was discontinued in the United States between 2000 and 2004. The medication appears to remain available only in India. Misuse of mephentermine for recreationa ...

Morphine
Morphine, formerly also called morphia, is an opiate that is found naturally in opium, a dark brown resin produced by drying the latex of opium poppies (''Papaver somniferum''). It is mainly used as an analgesic (pain medication). There are multiple methods used to administer morphine: oral; sublingual administration, sublingual; via inhalation; intramuscular, injection into a muscle, Subcutaneous injection, injection under the skin, or injection into the spinal cord area; transdermal; or via rectal administration, rectal suppository. It acts directly on the central nervous system (CNS) to induce analgesia and alter perception and emotional response to pain. Physical and psychological dependence and tolerance may develop with repeated administration. It can be taken for both acute pain and chronic pain and is frequently used for pain from myocardial infarction, kidney stones, and during Childbirth, labor. Its maximum effect is reached after about 20 minutes when administ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Enos (chimpanzee)
Enos (born about 1957 – died November 4, 1962) was a Common chimpanzee, chimpanzee launched into space by NASA, following his predecessor Ham (chimpanzee), Ham. He was the only chimpanzee, non-human primate to orbit the Earth, and the third hominid to do so after cosmonauts Yuri Gagarin and Gherman Titov. Enos's flight occurred on November 29, 1961. Enos was brought from the Miami Rare Bird Farm on April 3, 1960. He completed more than 1,250 training hours at the University of Kentucky and Holloman Air Force Base. Training was more intense for him than for Ham (chimpanzee), Ham, who had become the first great ape in space in January 1961, because Enos was exposed to weightlessness and higher g-force, ''g''s for longer periods of time. His training included psychomotor instruction and aircraft flights. Enos was selected for his Project Mercury flight only three days before launch. Two months prior, National Aeronautics and Space Administration, NASA launched Mercury-Atlas 4 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercury-Atlas 5
Mercury-Atlas 5 was an American spaceflight of the Mercury program. It was launched on November 29, 1961, with Enos, a chimpanzee, aboard. The craft orbited the Earth twice and splashed down about south of Bermuda, and Enos became the first primate from the United States and the third great ape to orbit the Earth. History By November 1961, the Soviet Union had launched Yuri Gagarin and Gherman Titov into orbit during the Vostok 1 and Vostok 2 crewed orbital flights while the United States had managed only suborbital ones. At that time NASA was still debating placing a chimpanzee in orbit as part of the Mercury-Atlas subprogram, with NASA headquarters questioning the wisdom of the Manned Spacecraft Center launching another uncrewed Mercury mission. The NASA Public Affairs Office issued a press release prior to the flight, stating "The men in charge of Project Mercury have insisted on orbiting the chimpanzee as a necessary preliminary checkout of the entire Mercury program be ...

Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...
