History Of Spaceflight
Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth, each of whom published works proposing rockets as the means for spaceflight. The first successful large-scale rocket programs were initiated in Nazi Germany by Wernher von Braun. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, the first animal, the first human and the first woman into orbit. The United States landed the first men on the Moon in 1969. Through the late 20th century, France, the United Kingdom, Japan, and China were also working on projects to reach space. Following the end of the Space Race, spaceflight has been characterized by greater international cooperation, cheaper access to low Earth orbit and an expansion of commercial ventures. Interplanetary probes have visited all of the planets in the Solar System, and humans have remained in orbit for long periods aboa ...

Spaceflight
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflights operate either by telerobotic or autonomous control. The first spaceflights began in the 1950s with the launches of the Soviet Sputnik satellites and American Explorer and Vanguard missions. Human spaceflight programs include the Soyuz, Shenzhou, the past Apollo Moon landing and the Space Shuttle programs. Other current spaceflight are conducted to the International Space Station and to China's Tiangong Space Station. Spaceflights include the launches of Earth observation and telecommunications satellites, interplanetary missions, the rendezvouses and dockings with space stations, and crewed spaceflights on sci ...

International Space Station
The International Space Station (ISS) is a large space station that was Assembly of the International Space Station, assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), European Space Agency, ESA (Europe), JAXA (Japan), and Canadian Space Agency, CSA (Canada). As the largest space station ever constructed, it primarily serves as a platform for conducting scientific experiments in microgravity and studying the space environment. The station is divided into two main sections: the Russian Orbital Segment (ROS), developed by Roscosmos, and the US Orbital Segment (USOS), built by NASA, ESA, JAXA, and CSA. A striking feature of the ISS is the Integrated Truss Structure, which connect the station’s vast system of solar panels and Spacecraft thermal control, radiators to its pressurized modules. These modules support diverse functions, including scientific research, crew habitation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slovenes
The Slovenes, also known as Slovenians ( ), are a South Slavs, South Slavic ethnic group native to Slovenia and adjacent regions in Italy, Austria and Hungary. Slovenes share a common ancestry, Slovenian culture, culture, and History of Slovenia, history, and speak Slovene language, Slovene as their native language. Although Slovenes are linguistically classified as South Slavs, genetic studies indicate they share closer genetic affinities with West Slavic and Central European populations than with other South Slavs such as Bulgarians and Macedonians. Outside of Slovenia and Europe, Slovenes form diaspora groups in the United States, Canada, Argentina and Brazil. Population Population in Slovenia Most Slovenes today live within the borders of the independent Slovenia (2,100,000 inhabitants, 83% Slovenes est. July 2020). In the Slovenian national census of 2002, 1,631,363 people ethnically declared themselves as Slovenes, while 1,723,434 people claimed Slovene as their nat ...

Liquid Fuel Rocket
A liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.) Liquids are desirable propellants because they have reasonably high density and their combustion products have high specific impulse (''I''sp). This allows the volume of the propellant tanks to be relatively low. Types Liquid rockets can be monopropellant rockets using a single type of propellant, or bipropellant rockets using two types of propellant. Tripropellant rockets using three types of propellant are rare. Liquid oxidizer propellants are also used in hybrid rockets, with some of the advantages of a solid rocket. Bipropellant liquid rockets use a liquid fuel such as liquid hydrogen or RP-1, and a liquid oxidizer such as liquid oxygen. The engine may be a cryogenic rocket engine, where the fuel and oxidizer, such as hydrogen and oxygen, are gases which have been liquefied at very low temperatures. Most designs of ...

De Laval Nozzle
A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, with a rapid convergence and gradual divergence. It is used to accelerate a compressible fluid to supersonic speeds in the axial (thrust) direction, by converting the thermal energy of the flow into kinetic energy. De Laval nozzles are widely used in some types of steam turbines and rocket engine nozzles. It also sees use in supersonic jet engines. Similar flow properties have been applied to jet streams within astrophysics. History Giovanni Battista Venturi designed converging-diverging tubes known as Venturi tubes for experiments on fluid pressure reduction effects when fluid flows through chokes ( Venturi effect). German engineer and inventor Ernst Körting supposedly switched to a converging-diverging nozzle in his steam jet pumps by 1878 after using convergent nozzles but these nozzles remained a company secret. Later, Swedish engineer Gustaf de Lav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The War Of The Worlds
''The War of the Worlds'' is a science fiction novel by English author H. G. Wells. It was written between 1895 and 1897, and serialised in '' Pearson's Magazine'' in the UK and ''Cosmopolitan'' magazine in the US in 1897. The full novel was first published in hardcover in 1898 by William Heinemann. ''The War of the Worlds'' is one of the earliest stories to detail a conflict between humankind and an extraterrestrial race. The novel is the first-person narrative of an unnamed protagonist in Surrey and his younger brother who escapes to Tillingham in Essex as London and Southern England are invaded by Martians. It is one of the most commented-on works in the science fiction canon. The plot is similar to other works of invasion literature from the same period and has been variously interpreted as a commentary on the theory of evolution, imperialism, and Victorian era fears, superstitions and prejudices. Wells later noted that inspiration for the plot was the catastrophic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The First Men In The Moon
''The First Men in the Moon'' by the English author H. G. Wells is a scientific romance, originally serialised in ''The Strand Magazine'' and '' The Cosmopolitan'' from November 1900 to June 1901 and published in hardcover in 1901. Wells called it one of his "fantastic stories". The novel recounts a journey to the Moon by the two English protagonists: a businessman narrator, Mr. Bedford; and an eccentric scientist, Mr. Cavor. Bedford and Cavor discover that the interior of the Moon is inhabited by a sophisticated extraterrestrial civilisation of insect-like creatures they call "Selenites". The novel is a major work in the long history of the Moon in science fiction, which dates back to classical antiquity and includes earlier encounters with lunar beings and civilisations, often satirical in nature. The scientific inspiration in large part would come from Jules Verne and his book From the Earth to the Moon in 1865, which used a cannon shot to launch a spacecraft with a human ...
