Mars: to go or not? This is a problemevery human civilization seeks to achieve the great cause, we can set up a monument for future generations, as the supreme evaluation of 2015 Latest Nike Shoes their value, demonstrating the essence of its civilization, and left evidence of the people who exist. The monument of the most important ideas to create, by the most delicate hand sanding and carving, proudly left children and grandchildren, some of which even dozens of generations pass continued. Establish a monument and innovative longing is the basic attributes of human society. Great first people have left us the pyramids, the Great Wall, the Panama Canal, the steam engine, railroads, skyscrapers, propeller, cars, planes, and even cave paintings. Each miracle, every innovation, are telling people who by virtue of their hearts, minds and hands kept in fact the world. Great achievements have improved the human condition, to establish the monument important technological progress. Today, we are no different. In the past nearly 60 years, we have been to get rid of the shackles of us on Earth gravity. Our satellites have already visited all the planets, as well as some asteroids and comets. We have left a footprint on the lunar surface. Although 40 years or so since we plugged the national flag after the moon, we have realized a lot of exciting and innovative, but the 'Apollo' moon has always been the pinnacle of our achievements. Now, as a state and nation, we confused a new Air Jordan 12 problem: Mars - to go or not? This is not a simple question to the contrary, it is an intense nationwide discussion and deep reflection. And for a space powers, it even led to more problems. To Mars, the value of it? US economy is currently heavily in debt, and many of the world where economies are crumbling. It is a difficult period. Millions of people were expelled from the labor market, but is no longer the Ministry of Labour and those sarcastic myopic bureaucrats identified as unemployed. Almost do not see signs of slowing down, the skeptics asked:? 'Before we make such a huge risk, why should not respond to the basic needs of the people first, parents, schools, public safety and the environment, why should not you will understand ?? How much you spend precious Air Jordan 11 national wealth since the real value of space exploration in the end is what 'Buzz Aldrin (Apollo 11 crew, together with the first ascent of the moon Armstrong - Translator's Note) and other talented hero once solemn In response to these disappointing remarks. Back in 2009, he was in his memoirs, 'gorgeous Huangtu' (Magnificent Desolation) clearly gives a perfect response: not our valuable lunar rocks brought back, nor to praise poem. These will soon be forgotten. And people will live to witness history. The resulting exploration of Mars can not be measured in return. For many people, one day we will establish a base on Mars a bit crazy idea. Then again, maybe not a dream. At the time I was born, the astronauts can fly landing on the moon and return Nike Air Max 90 VT safely screen is considered to be pure science fiction. However, Buzz Aldrin and Neil Armstrong just did. They jump around the moon surface, it inspired the whole world of imagination. Millions of Americans are very proud and excited to watch live. During that period, I still hesitated future career and academic planning. I remember talking with friends and neighbors, but also heard scientific Cynics say very confidently advanced electronic equipment useless in space. Some people warned that if human folly to go to space, their blood will be boiling. At least, they identify those space travelers become disoriented and therefore die. Of course, such a contempt has been refuted many great achievements. For example, in the not so long ago, the sound barrier was considered unassailable. However, in October 14, 1947, Chuck Yeager himself into a rocket ship where the leash door with a broom, then bravely prove the skeptics wrong. Jaeger feat no less than the great ancient European explorers who crossed a no waters on the map. Before departure they did not know what would be found in the other side. New knowledge and opportunities from the superior and fearlessly face unprecedented challenges. Only the courage to take risks, we as a species can evolve. They interpret the human spirit. But the idea Nike Air Max Excellerate+2 of immigration Mars really not going crazy? Perhaps, but the surface conditions on Mars are really closer to the Earth than the other solar system bodies. Martian environment is much stronger than extreme hot and cold temperatures Mercury, Venus furnace hot surfaces or outer planets and their satellites in extremely cold temperatures. Most environmental Mars can be realized on Earth. For example, cast manned balloon reached the highest altitude, which recently created the Red Bull Challenge record, has been close to 39,000 meters; pressure and the height of the surface of Mars on similar pressure. The Antarctic and Arctic cold environment is almost the same as the most extreme temperatures on Mars. Overall, however, Mars is not a very comfortable place. In short, Mars immigrants will pose serious challenges. So try migrants should not be trying to conquer the first step on Mars. As our earlier exploration of the moon, we should first to Mars, flying around and return safely to Earth. Once we are confident that you can successfully achieve ply, the next step should be to send astronauts up to assess and explore, then return safely. Next, we need visitors began to build sustainable infrastructure on Mars and return. Only when the infrastructure is in place, we should consider what Mars immigrants. However, in addition to 'wow! Oh!' Factor, worth? In 1961, President Kennedy responded to this never-ending problem. He said: We choose to go to the moon within a decade and do the other things, not because it is easy, but because it is quite difficult, because this goal would be enough to make us energy and skills leading to systematize and evaluate, because it challenges us willing to accept, reluctant to buck, aspirations ... In the modern era, there will not be any more shocking than its space program, space exploration have a more profound impact, it will not be harder than spend more ... The decision needs science and technology, human resources, materials, facilities of major national commitment. Kennedy's key point for any exploration of Mars, it is to 'make our energy and skills leading to systematize and evaluate' role immeasurable. Mars seeks to explore the set and then 'Apollo' same priority (but now a country of non-force) should serve as a driving force and catalyst for global technology innovation engine. Far-reaching implications for the Mars mission developed technologies generated will be compared with the moon. Another important value from a manned mission to Mars is: This will show US leadership in the international field of space technology. The United States won the leadership values and lessons from the Cold War space race, and has promoted the development of 'Apollo' and the space shuttle. Later, the United States and many other countries gradually formed together to build the foundation to run the International Space Station. Mars exploration initiative to re-inspire our domestic engineering industry and industrial base. Students encouraged by the exploration of Mars and other people may become engineering and scientific innovation, who for economic growth and technological progress is essential. A more subtle benefits manned mission to Mars is possible for human beings to prove there is a new awareness. Looking for evidence of life or life once existed on another planet Nike Air Max Unisex will change the way we are we can not imagine. Photo entire planet the way a person captured moon (Apollo 8 - Translator's Note) now still change our self-perception: our planet is so beautiful, so fragile, it communicates with each other and the universe, I do not see borders. How can refute arguments against the exploration of Mars? As we have discussed, taking into account the social challenges we face, many people have asked: 'In the earth there is so much trouble, why we have to spend billions in space?' For these two thankless controversial issues, can respond with another question: 'Now on Earth there are indeed many problems to be solved, but if you can not afford in the past 50 years by the United States to develop a space program, how do we deal with these problems?' information systems, materials technology and many other new developments in Air Jordan 5 the formation of our highly interdependent world. If there is no space technology, there is no NASA-developed meteorological and earth observation satellites, we may still be worried about climate change. If there is no development at NASA communications satellite, the error correction code and IC field, we also would not have advanced communications now depend for survival. The instinct to explore precisely reflects the requirements of the human spirit, but also reflects the continuous improvement to meet the significant curious desire. It is eager to continue to improve and endless curiosity drives our souls yearn for Mars. Thousands of people have expressed interest in applying for 'Mars One' one-way trip to Mars, as our ancient ancestors were the same as the global adventure. We're never satisfied with the status quo. We always count on a better way or do something with the new tools, or dangling, or canoeing, or sail to a new place, or experience a new adventure. We can afford it cost to go to Mars? In a sense, the simple answer is no. There are too many more pressing needs on Earth, the United States no money can be invested in such a senseless adventure. And, admittedly, the cost of manned Mars program will be very large. At this point, even resource-rich countries such as the United States will feel spending is too high. However, this is the case with the original moon is the same. So I think this challenge requires worldwide cooperation. Taking into account the cost pressures, we should let the private sector lead the way yet? 19th and 20th centuries most truly outrageous inventions are private individuals results: trains, steamships, airplanes, telephones, electrical lighting and so on. Space is too expensive for the private area. Moreover, the early space age nor an immediate return on investment. But times have changed? The private sector should take the lead, the first flight to Mars it? Wright brothers expert bicycle mechanic beat Samuel Langley, achieved first heavier than air aircraft sustained powered flight, despite President McKinley Langley provided $ 50,000 for the use of the funds to do it. Langley research engine, but we did not pay attention to all vital to the success of the flight aerodynamics, aircraft design, flight control, wind tunnel tests, and so on. Langley gadgets failed, again and again fell into the river. The Wright brothers did the right thing, in the absence of government funding conditions fame. Can replace government operations to Mars might be 'will act' organizations. Will conduct an entity different from ordinary private companies, they are not for profit, their pursuit of the challenge from advancing human achievement. There currently are more than ready to participate in the entity will conduct exploration of Mars, where the spotlight three are: Inspiration Mars (Inspiration Mars), is promoting the 2018 plan a manned mission to Mars flyby; gold nail company (Golden Spike) is exploring They take groups launch landing on the moon, a brief 'Apollo' type of residence; Mars One (Mars One), planned the first manned landing on Mars in 2023 and reside. For example, this private 'act of will' entities may be willing to take some risks the use of innovative technology to shorten the travel time to Mars mission. This will greatly reduce the radiation exposure of astronauts, while improving security. They are also willing to take the risk of occupant injury, just as circus performers and test pilots often risking their lives. These organizations may also bear the risk of other NASA never allowed. I guess, this view is lost each year to climb Mount Everest, but never stopped thinking life explorers held. Most unmanned (robotic) mission to Mars have failed. Entry, descent and landing (EDL) process is very complex and not fully understood. Even good in the good of the Jet Propulsion Laboratory, a lot of financial and human resources to test, test each sequence in each line of code, make sure the hardware independent, properly run, still inevitably encounter mission failed. Round-trip journey to Mars will not be easy. There are many private companies want to put the effort in, but also should have a key role of international partners. Unfortunately, a number of private entities think they can simply outsource parts and software, their task is merely to mobilize mature technology. They are too optimistic. Although these organizations have excellent engineers, but they did not really experienced the ordeal Mars mission, JPL engineers who has already gone through, these organizations lack: critical systems engineering skills and experience; enter, drop and landing expertise; responsible for systems engineering, development, integration and testing of the core management team and project managers; required identification number and the necessary software development and testing. A manned mission to Mars by the stimulation of great challenges and major federal funding should be a national goal. Now NASA annual budget of approximately 0.5% of the federal budget. After doubling the overall budget will disappear in the rounding error in. To Mars certainly fits Kennedy 'reach new heights,' the statement. We consider how to fix the US economy at the same time, we should also start to discuss international cooperation in the exploration of Mars. NASA needs some seed money, for the definition and development of key technical problems and solutions facing manned mission to Mars. Similarly, the need to continue to break the Jet Propulsion Laboratory related engineering and technical mission to Mars. The present era is no shortage of innovation, many achievements can be hailed as a great contribution to human evolution, from nuclear energy to nanotechnology and genetics and smart phones. Space must pursue competitive and sustainable energy, genetic engineering, artificial intelligence and other technologies. America is ready once again to Kennedy-style 'not because of trade, but because of difficult' challenges ahead in space yet?
