Academic performance and technology Essay Example for Free
Academic performance and technology EssaySpace exploration is the discovery and exploration of outer set by means of space technology. natural exploration of space is conducted both by human spacefarings and by robotic spacecraft. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of gargantuan and relatively efficient rockets during the early 20th century that allowed physical space exploration to become a reality.Common rationales for exploring space include advancing scientific research, uniting different nations, ensuring the future survival of humanity and developing military and strategic advantages against other countries. Space exploration has often been used as a proxy ambition for geopolitical rivalries such as the Cold War. The early era of space exploration was driven by a Space run for between the Soviet Union and the United States, the effect of the first man-made object to orbit the worl d, the USSRs Sputnik 1, on 4 October 1957, and the first moonlight landing by the Ameri provide Apollo 11 craft on 20 July 1969 are often taken as the boundaries for this initial period.See more Recruitment and selection cover essayThe Soviet space program achieved many of the first milestones, including the first living being in orbit in 1957, the first human spaceflight (Yuri Gagarin aboard Vostok 1) in 1961, the first spacewalk (by Aleksei Leonov) on 18 March 1965, the first automatic landing on another celestial body in 1966, and the launch of the first space station (Salyut 1) in 1971. After the first 20 years of exploration, focus shifted from one-off flights to renewable hardware, such as the Space Shuttle program, and from competition to cooperation as with the International Space Station (ISS). With the substantial completion of the ISS following STS-133 in March 2011, plans for space exploration by the USA remain in flux. Constellation, a Bush Administration program for a return to the Moon by 2020 was judged inadequately funded and unrealistic by an expert review panel coverage in 2009.The Obama Administration proposed a revision of Constellation in 2010 to focus on the development of the capability for crewed missions beyond low earth orbit (LEO), figure extending the operation of the ISS beyond 2020, transferring the development of launch vehicles for human crews from NASA to the private sector, and developing technology to enable missions to beyond LEO, such as Earth/Moon L1, the Moon, Earth/Sun L2, near-earth asteroids, and Phobos or Mars orbit.5 As of March 2011, the US Senate and House of Representatives are still working towards a compromise NASA funding bill, which will plausibly terminate Constellation and fund development of a heavy lift launch vehicle (HLLV).6 In the 2000s, the Peoples Republic of China initiated a successful man spaceflight program, while the European Union, Japan, and India have in like manner planned future manne d space missions.China, Russia, Japan, and India have advocated manned missions to the Moon during the 21st century, while the European Union has advocated manned missions to both the Moon and Mars during the 21st century. From the 1990s onwards, private interests began promoting space tourism and then private space exploration of the Moon (see Google Lunar X Prize).Benefits of this to MankindThere are critics who disagree with the expenditure on space exploration, which they claim can better be used to settle earthly problems. However, they seem to forget that this is one of the field of operations which tests a mans intellect. But, how does a common man draw benefits of space exploration? The advances made in field of space exploration can be well used in other fields such as medicine, agriculture, etc. The following is the list of benefits of space exploration to mankind spherical Positioning System The mankind depends on the sea trade for transportation of food grains, fossil fuels, metal ores, etc. Global navigation system, GPS helps in timely delivery of these essential goods by providing the ships with essential navigation information.The GNS services are made available using networks of transmits which also enables satellite Internet and satellite phones. Weather Forecast and Agriculture Gone are the days, when we used to take an umbrella with us while going out if there were black clouds in the sky. Now we can rely on the weather reports updated on an hourly basis. The accurate weather forecast is possible only because of the satellites in the space. The satellites also help us in predicting the crop yields, pest infestation and the area under cultivation. Natural Calamities It is easy to predict natural calamities such as floods, storms, tornadoes, hurricanes and to locate wildfires and their extent with the help of satellites. Minerals and Mining Minerals buried deep under the Earths surface can be located using satellites. Precious fossil fuel s can be found with the help of satellites. Electronics The field of electronics and computers have also benefited from the space exploration.The astronauts have make illumination electronic parts that could only be produced in the space during their experiments in the space stations and space shuttles. Asteroids It is believed that an asteroid strike eliminated the dinosaurs on the Earth. One of the benefits of space exploration is that we know about the thousands of asteroids and we can also be vigilant about their drifts. May be we could prevent dinosaurian death of mankind, if and when an asteroid is positioned to repeat history. If it happens, it would be because of the knowledge which is the direct benefit of space exploration. vigour Source The scientists and researchers all over the world are attempting to harness the power of nuclear fusion. The process which enables the Sun to produce energy in abundance. It is believed that quantity of electricity generated using 1kg of hydrogen would be equivalent to that of 11,000 metric tons of coal.Medicine Another field to glean the benefits of the satellite exploration is that of medicine. Metal alloys that are manufactured to be used in spacecraft and space shuttles are also used in the health care industry. Nitinol, an alloy is used to make braces. The miniature electronic components which were developed for the space program can be used in electronic pain-control device that some patients need to use. The implantable insulin pump is based on the mechanical robot arm developed for the Mars Voyager probe. The space exploration benefits also encompasses the field of communication which needs no explanation. The applications of knowledge and the technologies, that are the issue of the mans efforts to explore space, are making his life easier indeed
