Space travel is one of the most urgent problems of modern civilization. Although the knowledge of people about traveling into the space is rooted in the history, the actual space traveling became possible only in the 20th century with the development of rocket technology. Undoubtedly, space travel is not a country picnic. Moderate temperature and atmospheric pressure fluctuations seem natural for us. However, in deep space humans will have to face the fact that most of the universe is in a state of chaos and there are deadly radiation belts and meteor swarms.

The first problem of a long space travel to be solved is weightlessness. Conducted long-term studies of weightlessness have shown that the human body in space loses minerals necessary for life and chemicals much faster than expected. Even a tough program of physical exercise cannot save the situation: after a year on the space station astronauts bones and muscles atrophy so that when they return to Earth, they are only able to crawl like infants. It seems that the logical consequences of a prolonged staying in weightlessness during space flight are muscle atrophy, deterioration of the locomotor system, reducing the production of red blood cells, decreasing immune response, weakening cardiovascular activity. Flight to Mars, which can last from several months to a year, is located on the edge of the boundary endurance of the astronauts. On long flights to the nearby stars, this problem can be fatal (Davis).

The second problem is that because of the presence of meteorites in space, moving at speeds of tens of kilometers per second may need to equip…...

Physics and Space Travel

...Physics and Space Travel The human race has always been fascinated by the concept of outer space and what lies beyond our Earth. Mankind’s innate curiosity has inspired numerous technological advancements that have made it possible for humans to travel into space and explore what was previously only the subject of dreams and imagination. Early writings such as The Brick Moon by Edward Everett Hale illustrate how little was actually known about outer space, and the physical and practical limitations humans must overcome to escape Earth’s gravity. The Brick Moon is a science fiction short story written in the 1800s and it is one of the first known writings to describe the construction and launch of not only an artificial satellite, but also a space station (Wikipedia, 2011). The story The Brick Moon outlines some of the building blocks for modern day space technology and travel but the approach used in the book is impractical for real world application. The Brick Moon is written from the perspective of one of the main characters and recounts how he and his friends planned, funded, constructed, and eventually launched a satellite or manmade “moon” into space. The purpose of the Brick Moon was to act as a navigational aid for ships at sea. The idea was based around the North Star, which sailors used as a guide to determine their latitudinal location; the inventors wanted to launch the Brick Moon to orbit along the Prime Meridian so that sailors could just as easily......

The International Student Travel Market: Travelstyle, Motivations, and Activities

...THE INTERNATIONAL STUDENT TRAVEL MARKET: TRAVELSTYLE, MOTIVATIONS, AND ACTIVITIES GREG RICHARDS* and JULIE WILSON† *Fundació Interarts (Interarts Foundation) and Rovira i Virgili University, Tarragona, Spain †Department of Geography and History, Rovira i Virgili University, Tarragona, Spain Abstract: One sign of the growing interest in student travel both from the tourism industry and academic researchers is the global independent travel survey conducted by the International Student Travel Confederation (ISTC) and the Association for Tourism and Leisure Education (ATLAS). The survey, conducted in 2002, covers the profile and travel behavior of 1630 students booking travel from student travel organizations in eight countries. This article reports the initial results of this research. The survey showed that students are frequent travel consumers with extensive previous experience of relatively long trips outside of their own world region. Most students see their travelstyle as that of “traveler,” but a significant proportion of the market characterized their travel as “backpacking.” Motivations reflecting a desire for experience are prevalent with student travelers, particularly in terms of exploring other cultures. Motivations tend to be differentiated by destination region and travelstyle and are distinct between students and other young travelers. In spite of these differences in motivation, however, the activities actually engaged in showed little differentiation......

...know about them and make them even better. Looking at the technological advancements of the computer over the years, it leaves you wondering where we’ll be in 20 or 30 years. Businesses jumped on the idea that a personal computer could benefit them. They also found out that owning one, not only made their business more efficient, but also made running their business much easier. The Personal computer became so popular during the late 70s that they found ways to use them for a variety of reasons. They include the use of office applications, home finance organization, storing data and many more options. The computer seemed to have made things a little easier. In the 1990’s, the PC became mainstream. In 1990 the Hubble telescope was put in space and Microsoft was the first company to exceed $1 billion in sales. In 1994 Vice President Gore coined the term “Information Superhighway”. The way the computer impacted the 90’s was unimaginable. From blackberry to yahoo mail and coming online, the computer was changing everyday life thanks to the internet. People started to rely on the computer for everyday use whether at home or in the office. By the 21st century, people started to realize the impact of the Personal Computer. We realized the paranoia when the new millennium was fast approaching. People started to believe that the end of the world was near. With this idea in mind they came up with the term “Y2K,” and then 2000 came and nothing happened. By 2058, the......

...superstructure for growth. Space Tourism:- These days, technological advancements made space exploration possible. For others, this will be a tremendous form of tourism. Since the human minds and modern technology still need to unravel the hidden mysteries of the space, hence, they have to study and work rigorously, to know every single detail, to become successful in this newly found activity A major beneficial effect of space tourism is it will drastically broaden and enrich people's technical awareness and constructive knowledge of the outer-space.. As a result, these various information will validate and heighten people's ideas about the space. Exploring the outer-space by tourists will also impact positively on a government's economic status. This type of recreational activity could probably immensely increase the number of employment. An extensive man power, for instance, is very necessary to be able to facilitate an extraordinary kind of recreation. In line with this, space tourism will also contribute to the growth of national revenues. Thus, it will make a country infinitely rich. On the other hand, visiting the outside-earth might significantly affect the society and the environment in a negative way. No doubt, this type of spacecraft will produce harmful emissions such as huge amount of carbon dioxide. Consequently, such substance will exacerbate global warming and will affect both people and the environment perniciously. The means of transportation for space......

Commercial Space Travel

...great risks associated with being blasted into space and then gliding back to earth. Many systems must work almost flawlessly for day-in and day-out space travel. This is rocket science after all. From your perspective, would you be an early adopter and want to be one of the first to fly into space? Or would you wait until the industry was more mature? What factors would you include when thinking about commercial space travel? With the development of science, more and more new technologies come to this world. The SpaceShipOne crossed the finish line, and winning the Ansari X Prize with its second spaceflight. The world's first privately developed spacecraft also broke a 41-year-old altitude record and created a new astronaut. This is an exciting new for people who are really want to go to space for travel. However, I will definitely wait until the industry was more mature. I think the commercial space travel is not a normal travel, it is a big deal. When I think about go to space travel, I have to think about few factors. First of all, it is really expensive. Unless you are super rich, normal people cannot afford to travel to space. Thus, in many people's minds, space travel seems to be an unreachable dream. Especially for those people who are the early adopter or the first to fly into space, they must need to pay the whopping price. All the rich people from all over the world will come to this only one commercial space travel place, and it will be the big competition......

Wormholes and the Possibility of Travel Through Space-Time

...Name Tutor Course Title Wormholes and the possibility of travel through space-time Description After a critical analysis of various topics, the topic for this discussion is going to be wormholes and the possibility of travel through space-time. The research looked at understanding what wormhole is, and the findings were that this is a theoretical passage that happens through the specimen. It is possible of creating shortcuts for the long journeys that could take place in the universe. The general theory of general relativity has been used to explain and predict wormholes. Wormholes discovery The Wormholes theory can trace its root up to the year 1935 when a well-known genius and physicist Albert Einstein and Nathan Rosen discussed and used the theory of general relativity. It was used in proposing for the existences of bridges through space-time. It is these bridges or the pathways that were called the Einstein-Rosen bridges or the Wormholes. The main purpose of the two is to connect two different points in space-time thus when looked and explained theoretically they created a shortcut that could reduce the travel time and also the distance. There is something to worry about the wormholes is that they bring with them risks and dangers of sudden collapsing that is associated with high radiation and other hazardous dangers when in contact with exotic matter. Wormholes space-time in the scientific community The need to integrate wormholes into the scientific......

The Realities of Space Travel

...  Lydia Fields  Mrs. Price  10th Advanced Literature  20 May 2015  The Realities of Space Travel  Dreams of space travel became a reality when ​ cosmonaut Yuri Gagarin, a Russian,  became the first human to make it into space in 1961. He successfully made a 108­minute orbital  flight in his Vostok 1 spacecraft. Though this was a major milestone in history, there was still  many facts about space travel that scientists were not yet aware of. ​ Orson Scott Card wrote  Ender’s Game​ , a futuristic book where the main setting is in space, in 1985. He then rewrote it in  1991 to better the accuracy of certain facts throughout the book. As time went on, scientists  continued to discover the realities of space travel; therefore, Card would need to update facts  about how people age in space, traveling at the speed of light, and the effects of space travel on  the human body to, once again, make ​ Ender’s Game​  an accurate novel.  Though people in space age slower than humans on earth, they only gain 0.007 seconds  of extra life over a period of six months. The most important difference between aging on earth  and aging in space is the aging process. This process typically includes bones becoming brittle,  blood vessels hardening, muscles wasting away, joints stiffening up, bowels turning irritable,  bladders becoming unpredictable, teeth decaying, vision growing dim, and skin wrinkling up.  Jessika Toothman explains this when she says, “While for most peo......

...I. Introduction: The purpose of this paper is an overview about the current space tourism industry with advanced developments of space vehicles. Until now, seven tourists have ridden Soyuz spacecraft, a Russian spacecraft, to the International Space Station. Capturing the potential demand of space tourism, many private companies began to introduce their new and well-designed spacecraft promising to enable tourist to travel to space. From now to the next couple of years, we are expected to see many launches including testing and commercial flights into suborbital and low Earth orbit. There are also some private companies, who were awarded by NASA for their space programs to carry astronauts to the space station. II. Virgin Galactic – Scaled Composites (Suborbital): Virgin Galactic – Scaled Composites founded by Burt Rutan designed a unique type of spacecraft. Using a mothership aircraft, the space plane will be carried to midair and then be released to launch toward the edge of the atmosphere. Using carbon composite construction, the company has introduced two version of the space plane: SpaceShipOne and SpaceShipTwo along with two model of the mothership aircraft: WhiteKnightOne and WhiteKnightTwo. (Ref 1,3) A. Spaceship: a. SpaceshipOne – WhiteKnightOne: Scaled Composites first launched the SpaceShipOne to the suborbital in 2004 while the first of WhiteKnightOne was in 2002. Overall, the WhiteKnightOne’s features are carriage and launch of payloads up to 7...

...advantageous alignment of a planet and its parent star in the system HD 189733, which is 63 light-years from Earth, enabled NASA’s Chandra X-ray Observatory and the European Space Agency’s XMM Newton Observatory to observe a dip in X-ray intensity as the planet transited the star. "Thousands of planet candidates have been seen to transit in only optical light," said Katja Poppenhaeger of Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., who led a new study to be published in the Aug. 10 edition of The Astrophysical Journal. "Finally being able to study one in X-rays is important because it reveals new information about the properties of an exoplanet." The team used Chandra to observe six transits and data from XMM Newton observations of one. The planet, known as HD 189733b, is a hot Jupiter, meaning it is similar in size to Jupiter in our solar system but in very close orbit around its star. HD 189733b is more than 30 times closer to its star than Earth is to the sun. It orbits the star once every 2.2 days. HD 189733b is the closest hot Jupiter to Earth, which makes it a prime target for astronomers who want to learn more about this type of exoplanet and the atmosphere around it. They have used NASA's Kepler space telescope to study it at optical wavelengths, and NASA's Hubble Space Telescope to confirm it is blue in color as a result of the preferential scattering of blue light by silicate particles in its atmosphere. The study with......

Space were, the real world is no episode of Star Trek or Doctor Who. The initial exploration of space was met with extreme enthusiasm, but since then, the positive look on space travel has become almost non-existent, and for good reasons. To be blunt, the costs are outweighing the benefits. We have hoped for discovering Earth-like planets and other inhabitants in our universe, but these hopes have been squashed considering how large the universe is, and how impossible the possibility of reaping the benefits from the large task is. Earth is our home now, and we must deal with its problems first before we deal with any other planets. Earth’s issues must be tackled first, for the sake of our planet and everyone, man or animal, on it. Money is always an issue, no matter what. When looking at the “Pennies of Each Federal Spending Dollar” chart, space travel is so low in the national budget that it is included in the “all others” section, which only makes up 6% of the budget. Even when we went to the moon, there was no monetary return, so space travel is a waste of resources. We need all the extra money it can gather to protect our planet. Russell Roberts, a space enthusiast from the National Public Radio, said to “Leave the money here on Earth.” Like many others, he sees no point in using taxpayer dollars for useless, hopeless expeditions. Even though the freedom of traveling through space is promising, “we would do well to remember that we do not have a very good track record in......

...chance to buy shares in the company at a 20 percent discount under a share save scheme or through a matching option of one free share for every 10 bought under a share incentive plan (Sip). The travel operator has introduced the all-employee schemes in an effort to retain and motivate its existing staff. Anna Sparkes, HR consultant, policy development at Thomas Cook, said: “The main reasons for the launch were to retain staff and give employees a vested interest in the company on an ongoing basis.” Invitations were sent out to employees on 19 May, options were granted on 16 June, and the first employee payroll deductions for the schemes were made in July. Of Thomas Cook’s 19,000 employees, 14,000 were eligible to take part in either the Sip or the share save scheme. To join, they had to be based in the UK and have worked for the company for at least six months. Almost one-fifth (18.5 percent) of those who are eligible joined one of the schemes or both. Under the share save scheme, employees can save between £5 and £250 a month for a period of three years, at which point they can choose to buy shares at 20 percent below the option price. Under the Sip, employees buy shares each month and then, after five years, have the option of selling the shares tax efficiently. The travel firm communicated the schemes by sending out invitations to all eligible employees and putting up posters around the workplace. The company, which was floated on the London Stock Exchange in......

Space Travel

...used in helping mankind to get as far as they have with understanding physics. Space travel is possible because of the theories that Newton provided us with and you can see that in the movie Apollo 13, which retells a story of three astronauts who use mainly the laws of physics to get back to Earth after their space shuttle is damaged from an explosion. In the following paragraphs I will provide some examples from the movie of Newton’s first law, third law and his law of universal gravitation. Newton’s first law otherwise known as the law of inertia, states that an object at rest will continue to stay at rest and an object in motion will continue to stay in motion unless acted on my an external force. This law is shown throughout the entire movie when the space ship is in outer space. Due to the lack of gravity outside of the Earth’s atmosphere, the space craft moves in uniform motion in the same direction unless acted on by another force such as meteors or the rocket boosters. The third law that Isaac Newton produced states that for every action force there is an equal and opposite reaction force. An example to represent this law can be seen when the astronauts use the rocket engines to shoot out gas molecules. These gas molecules are shot out of the back of their shuttle and as stated by Newton’s law, their must be an equal and opposite reaction force which is used to accelerate the space shuttle. Another one of Newton’s laws states that any two objects in the......
