Dogs In Space
During the 1950s and 1960s the Soviet space program used dogs for sub-orbital and orbital space flights to determine whether human spaceflight was feasible. In this period, the Soviet Union launched missions with passenger slots for at least 57 dogs. The number of dogs in space is smaller, as some dogs flew more than once. Most survived; the few that died were lost mostly through technical failures, according to the parameters of the test. A notable exception is Laika, the first animal to be sent into orbit, whose death during the 3 November 1957 Sputnik 2 mission was expected from its outset. Training Dogs were the preferred animal for the experiments because scientists felt dogs were well suited to endure long periods of inactivity. As part of their training, they were confined in small boxes for 15–20 days at a time. Stray dogs, rather than animals accustomed to living in a house, were chosen because the scientists felt they would be able to tolerate the rigorous and ...

Anatoli Blagonravov
Anatoly Arkadevich Blagonravov (russian: Анатолий Аркадьевич Благонравов; – 4 February 1975) was a Soviet engineer and diplomat. He represented the Soviet Union on the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS). He worked closely with Hugh Dryden, his American counterpart, to promote international cooperation on space projects at the height of the Cold War. Anatoli adopted a dog named Tsygan, one of the first dogs to make a successful sub-orbital flight in 1951. Blagonravov died at the age of 80 in Moscow. Start of US/Soviet spaceflight cooperation Blagonravov was instrumental in opening the door to international cooperation in human spaceflight. After John Glenn's orbital flight, an exchange of letters between President John F. Kennedy and Soviet Premiere Nikita Khrushchev led to a series of discussions led by Blagonravov and NASA Deputy Director Hugh Dryden. Their talks in 1962 led to the Dryden-Blagonravov agree ...

Atmospheric Entry
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Crewed space vehicles must be slowed to subsonic speed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sputnik 6
Korabl-Sputnik 3 (russian: Корабль-Спутник 3 meaning ''Ship-Satellite 3'') or Vostok-1K No.3, also known as Sputnik 6 in the West, was a Soviet spacecraft which was launched in 1960. It was a test flight of the Vostok spacecraft, carrying two dogs; Pcholka and Mushka ("little bee" and "little fly"; affectionate diminutives of "pchela" and "mukha", respectively), as well as a television camera and scientific instruments. Korabl-Sputnik 3 was launched at 07:30:04 UTC on 1 December 1960, atop a Vostok-L carrier rocket flying from Site 1/5 at the Baikonur Cosmodrome. It was successfully placed into low Earth orbit. The flight lasted one day, after which the spacecraft was deorbited ahead of its planned recovery. The deorbit burn began at 07:15 UTC on 2 December, however the engine did not cut off as planned at the end of the burn, and instead the spacecraft's fuel burned to depletion. This resulted in it reentering the atmosphere on a trajectory which might have permitte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korabl-Sputnik 2
Korabl-Sputnik 2 (russian: Корабль-Спутник 2, lit=Ship-Satellite 2), also known as Sputnik 5 in the West, was a Soviet Union, Soviet artificial satellite, and the third test flight of the Vostok spacecraft. It was the first spaceflight to send animals into orbit and return them safely back to Earth, including two Soviet space dogs, Belka and Strelka. Launched on 19 August 1960, it paved the way for the first human orbital flight, Vostok 1, which was launched less than eight months later. Background Korabl-Sputnik 2 was the second attempt to launch a Vostok capsule with dogs on board. The first try on 28 July, carrying a pair named Bars (Snow Leopard aka Chaika (Seagull)) and Lisichka (Foxie), had been unsuccessful after the Blok G strap-on suffered a fire and breakdown in one of the combustion chambers, followed by its breaking off of the booster 19 seconds after launch. Around 30 seconds, the launch vehicle disintegrated, the core and strap-ons flying in random ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squirrel
Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and to the dormice. Etymology The word ''squirrel'', first attested in 1327, comes from the Anglo-Norman which is from the Old French , the reflex of a Latin word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. The native Old English word for the squirrel, , survived only into Middle English (as ) before being replaced. The Old English word is of Common Germanic origin, cognat ...

Sputnik
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'' when ...

Media Of The United States
Mass media in the United States consist of several types of media: television, radio, cinema, newspapers, magazines, and web sites. The U.S. also has a strong music industry. New York City, Manhattan in particular, and to a lesser extent Los Angeles, are considered the epicenters of U.S. media. Many media entities are controlled by large for-profit corporations who reap revenue from advertising, subscriptions, and sale of copyrighted material. American media conglomerates tend to be leading global players, generating large revenues as well as large opposition in many parts of the world. With the passage of the Telecommunications Act of 1996, further deregulation and convergence are under way, leading to mega-mergers, further concentration of media ownership, and the emergence of multinational media conglomerates. These mergers enable tighter control of information. Currently, five corporations control roughly 90% of the media. Critics allege that localism, local news and ...

Albert II (monkey)
Albert II, a male rhesus macaque (''Macaca mulatta''), was the first primate and first mammal in space. He flew from Holloman Air Force Base in New Mexico, United States, to an altitude of 83 miles (134 km) aboard a U.S. V-2 sounding rocket on June 14, 1949. Albert died upon reentry after a parachute failure caused Albert's capsule to strike the ground at high speed. Albert's respiratory and cardiological data were recorded up to the moment of impact. Albert II's flight, run by the Alamogordo Guided Missile Test Base and organized with the help of Holloman Air Force Base, followed the likely preflight death of Albert I before a high mesospheric flight aboard a V-2 rocket on June 11, 1948. The capsule was redesigned in-between flights to enlarge the cramped quarters experienced by Albert I.

Seagull
Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns and skimmers and only distantly related to auks, and even more distantly to waders. Until the 21st century, most gulls were placed in the genus ''Larus'', but that arrangement is now considered polyphyletic, leading to the resurrection of several genera. An older name for gulls is mews, which is cognate with German ''Möwe'', Danish ''måge'', Swedish ''mås'', Dutch ''meeuw'', Norwegian ''måke''/''måse'' and French ''mouette'', and can still be found in certain regional dialects. Gulls are typically medium to large in size, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls; stout, longish bills; and webbed feet. Most gulls are ground-nesting carnivores which take live food or scavenge opportunistically, particularly the ''Larus'' species. Live food often includes crustac ...

Snow Leopard
The snow leopard (''Panthera uncia''), also known as the ounce, is a Felidae, felid in the genus ''Panthera'' native to the mountain ranges of Central Asia, Central and South Asia. It is listed as Vulnerable species, Vulnerable on the IUCN Red List because the global population is estimated to number fewer than 10,000 mature individuals and is expected to decline about 10% by 2040. It is threatened by poaching and habitat destruction following infrastructural developments. It inhabits Alpine climate, alpine and subalpine zones at elevations of , ranging from eastern Afghanistan, the Himalayas and the Tibetan Plateau to southern Siberia, Mongolia and western China. In the northern part of its range, it also lives at lower elevations. Taxonomy (biology), Taxonomically, the snow leopard was long classified in the monotypic genus ''Uncia''. Since Phylogenetics, phylogenetic studies revealed the relationships among ''Panthera'' species, it has been considered a member of that Genus ( ...
