Space tourism is the most atypical form of tourism ever. After half a century from the first man in space we have entered the era of commercial space transportation. This era will not only change the technological scenario and our way of seeing space, but it will also bring greater popularity and participation towards the new space race. In fact, it will create a new sector in which to build businesses, but above all it will bring a new vision of the way people will travel in space. It is from the 50s that it has been spoken about space tourism. Robert A. Heinlein in one of his books in 1957, advanced for the first time the hypothesis of a future where the space voyage would be used as a form of tourism (Wainwright, n.d.). In 1985, the travel agency Society Expedition launched the "Space voyage " project, to sell short trips into the Earth orbit at a really high price (Wainwright, n.d.). Unfortunately, the project failed. In the mid-90s, the idea of space tourism become the...

We live in a world in which the thirst for technology has increased dramatically in recent years. Because of the expansion of technological innovations, humanity has been able to create devices that could not even be imagined a few years ago. One of the best technological innovations we have created in this century are the UAVs, which are changing the way we see and interact with the world. Seeing a UAV fly over our head is becoming a usual scene nowadays. In recent years, the presence UAVs on the market has allowed their use to be within everyone's reach, for a large number of purposes. There are numerous uses associated with the drones, in a wide range of areas, and here are some of the most important in which drones ensure, with their service, an improvement in the retrieval of information, with a result that often increases social security and life quality. The assembly of infrastructures and construction sites. The technological advances of drones are the result of careful...

The fatigue issue, within the aviation field, is a topic that has been discussed since the historical transoceanic flight of Lindbergh but it has never given much importance to the subject. Since then, scientific knowledge on fatigue has grown enormously. However, it cannot be said that the regulations have evolved accordingly. Nowadays, technology and operational changes within aviation have brought the issue to a critical point. Airplanes now fly over 16 hours without interruption, operations at night time have become almost the norm, even in the medium range. Huge economic pressures create the conditions for a further increase in fatigue. Fatigue, as proven by numerous studies, influences memory, attention to detail, the ability to communicate and make decisions. It is nothing less than an experience of physical and mental weakness that results in a reduction of attention. For most people, the primary cause of this fatigue is the lack of rest. It was an excessive fatigue on the pa...
