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 spaceships with additional protection. It is likely that the spacecraft of the future will have to arrange a special room for crew and supply its dual protection (Collins). Another problem is that the level of radiation in deep space is much higher than it has been previously expected. In deep space, where there is no protection of the Earth's atmosphere and its magnetic field, radiation can be a significant problem (Johnson). Even if the space company will be able to build a rocket spaceship, the way to the nearest stars will take decades, if not centuries. For such a flight it would take a several generations of crew, and the destination would be reached only by the descendants of those who went on the road. One of the solution of this problem is to subject space travelers in a state of anabiosis. This means careful and slow lowering of the body temperature to a level at which the implementation of all vital functions almost stops (Collins). It is worth noticing that the scientists have achieved great success in this field in recent years. However, it will take decades before this technique can be applied to the astronauts, and they may have to hold them in a state of anabiosis for centuries.

In the world history, there are well-known tragic incidents associated with the space research. One of the most famous of these unfortunate events was on January 27, 1967. The Apollo 1, caught fire during its simulation launch, killing all crew members (The History of Space Exploration, 2014). This terrible tragedy really affected both the Americans and the rest of the world. These tragic events compel researchers and developers to look forward for new ways and develop techniques to protect the spaceflight from all possible confusions.

Although there are still a lot of different obstacles for the space exploration, humanity has a hope that soon it will come to a new level of its development. All the necessary technologies will be developed, and the space exploring will become much easier and most importantly, safe for life. Furthermore, the encounter with the extraterrestrial life forms in space might become real.

Current Market Outlook for Space Business of Space Tourism

...Current Market Outlook for Space Business of Space Tourism Abstract This report covers some potential obstacles countries and companies may face when developing space tourism programs. The biggest hurdle will be the technology; companies like SpaceX, Boeing, and Virgin Galactic have good designs, but making those designs may prove to be more difficult. Another big issue that needs to be addressed is International Space Law. Many of the treaties were written at the beginning of the space race and only apply to trained astronauts. There will need to be new or revised treaties to cover the limits of private companies and the civilians they transport to space. The third issue covered is the safety and ethics of sending humans to space for a profit. Trained astronauts go through extensive programs to ensure they are ready for the elements of space. Proper measures will need to be taken to make sure civilians will have a safe and enjoyable trip. All of these topics are addressed in detail in this report; in the end however, it is evident that a few companies are on the right path to sending tourists to space. Introduction For centuries, the idea of space has intrigued scientists and engineers who constantly searched for ways to learn more and eventually get there. In 1961, during the heart of the Cold War, Russian cosmonaut, Yuri Gagarin, became the first person in space. Ever since that first major accomplishment, space agencies around the world have tried to push...

Facilities like pool complexes, spas, gyms, golf and other recreational activities can become expected amenities. Hotel management companies focus managers and budgets to cash flow, profitability targets, and occupation cost demands. However, the industry is changing rapidly, with substitute business models coming up. A Marketline Industry profile of April 2014, described “A new substitute in the form of private rentals, widely available through on line services such as Airbnb and Flipkey is a potential threat to the hospitality industry.” Chains such as Airbnb are described as being an emerging threat to the hotel industry. Airbnb has accomplished more growth than the top 10 global hotel companies have been able to grow in 20 to 240 years.

Obstacles to Mars Travel

...Obstacles and Solutions for Human Travel and Exploration of Mars Man is not destined to stand idle in the face of new frontiers and undiscovered fortunes. Since the beginning of time, man has risked nothing short of his own life to step beyond dreams and achieve the reality of the new and undiscovered. With the need to find these new corners of the universe, new technologies must be achieved giving man not only the abilities to overcome the impossible but the opportunity to better understand man himself. The conquest of Mars is a necessary step to exponentially leap man’s knowledge into new realms of understanding. The conquest of Mars is no longer an option but a necessity. I have been tasked today to present to my audience the obstacles and solutions associated with human interplanetary travel with respect to Mars. While many current fuel and propulsions systems are purely hypothetical, the idea to propel is basically the same. The principle is based on Newton’s Third Law of Motion: For every action, there is an equal and opposite reaction. As propellant is expelled from the spacecraft, a reactionary force is acted upon the spacecraft creating movement. This can be done in many forms including chemical propellant, electricity, nuclear, and solar sails. Chemical propulsion systems are the current propulsion systems of choice in the current world’s space programs. Chemical propulsion systems contain a fuel source and oxidizing agent that are mixed and burned in......

Investor Pitch to Headout

...Headout, a mobile travel application that functions as sort of a mobile concierge, helping you find tours, activities and tickets to local events in select U.S. cities, has closed on $1.8 million in seed funding in order to expand its business to new markets. Currently only live in New York and Los Angeles, the startup says it plans to utilize the funds to reach 12 more cities by year-end. This includes expansions into San Francisco, Los Angeles, Chicago, Washington D.C., Miami, and others over the next few months. Describing itself as an “Uber for tours,” the startup first began as Bangalore-based Tourlandish, and was initially targeting travel to and from Asia. But the company, which later participated in the 500 Startups accelerator program, shut down that app and relaunched with one focused on New York tours and events instead. After being live in New York for around six months, Headout launched in Las Vegas as its second supported city. Today, Headout has close to 500 last-minute activities available in its application, which the startup reports are anywhere from five to ten times more than its competitors offer. There are also 300 more vendors on waitlists for inclusion. Not all vendors are able to participate in Headout, however. Instead, the company tests out the activities in advance in order to vet them. If approved, the vendors are then given access to their own standalone mobile application that allows them to control when their activities are made......

...them? Examining the benefits of mixed-use developments, it is surprising that they have not been the norm until now. When jobs, housing and commercial activities are located close together, quality of life improves and the property values also increase. It is an ideal use of FSI and goes a long way in de-risking the development for developers. Internationally, mixed-use has been more popular in the last two decades. An ideal mixed-use town centre uses drivable streets connected to the local street grid and public spaces as anchors. In many parts of the world, retail is a part and parcel of mixed-use developments. Shopping malls such as Skyplaza in Hong Kong are planned within or alongside office, hotel and residential blocks. Modern airports in India and abroad require designers to plan for extensive retail capacity and flexible spaces that appeal to shoppers in transit. Zahir Abbas, AVP Retail, Technopak Advisors, says, “With the dynamics and pressures of the changing economic climate, businesses are constantly looking for new ways to generate revenues and enhance productivities from a land space.” In the US, a decline in retail activity is causing conventional shopping centres to search for new purposes. Medical centres and education are making use of space in defunct malls or office parks. Vacant retail space is being converted to community services and other non-retail purposes.

Internet in Daily Life

...The Internet is the global system of interconnected mainframe, personal, and wireless computer networks that use the Internet protocol suite (TCP/IP) to link billions of devices worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, Usenet newsgroups, telephony, and peer-to-peer networks for file sharing. Although the Internet protocol suite has been used by academia and the military industrial complex since the early 1980s, rapid adoption of its use was driven by events of the late 1980s and 1990s such as more powerful and affordable computers, the advent of fiber optics, the popularization of HTTP and the Web browser, and a push towards opening the technology to commerce. Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the 21 years since 1995, Internet use has grown 100-times to reach over one third of the world population,[1][2] leading to its services and technologies being incorporated into virtually every aspect of contemporary life.
