Flight to Mars
Flight to Mars is planned by several countries, who are ready to launch to the red planet manned spacecraft within the next 30 years. However, despite such promising prospects, scholars continue to argue about the feasibility of such a flight.
You should start with the fact that one-way flight will take on a variety of calculations, from 7 to 9 months. Such a long flight is very dangerous as the technical side (increasing the probability of hardware failures) and physiological and also the psychological side. Will the astronauts be so many months in a confined space with very limited contacts? How will it affect the human body for long periods in a weightless condition? How great is the danger of radiation in interplanetary space? All these questions become very relevant in the context of emerging in a not too distant future flight to the red planet.
However, should carefully consider possible consequences and unforeseen circumstances that may confront astronauts involved in such a long expedition. First of all, you should bear in mind that absolutely not possible to interrupt the mission due to any circumstances, or to deliver to Mars new reserves in case of shortage. In this case the crew can only rely on their own strength. This means that it needs to be ready for any eventuality, to be able to repair the equipment, and even manufacture new parts. Initially it is impossible to gather enough stock for such a long flight, so the astronauts will have to grow their own vegetables and fruit and clean air and water with the help of special equipment. In other words, the astronauts will have to deal with the maintenance of life.
Some scientists consider the option to artificially force the astronauts to fall “asleep” during the flight. For this purpose experts suggest to use hydrogen sulfide, which would have slowed down the process of metabolism without circulatory disorders in the body. However, this method requires many years of research.
Also experts recommend the entire crew to perform preventive surgery to remove the Appendix “just in case”. Otherwise, the astronauts may face this problem during the flight. Among other things, prior to such flight it is necessary to solve a number of ethical issues, because for such a long time any possible development of events, ranging from conflicts among the astronauts, ending with the death of one of them during the expedition. In other words, a detailed manual that explains how to operate the astronauts in a difficult situation.
The most difficult ethical issue at the moment is the disagreement of scientists about whether the astronauts to return to Earth. Some astronomers suggested a one-way trip from the base in the first Mars colony. Scientists argue this as follows. First, it is still unknown what problems astronauts will face during takeoff from the surface of Mars, which has a completely different gravity. Secondly, the return will cost countries is too expensive, given that scientists cannot guarantee that the flight back will be successful. Therefore, experts are seriously considering the idea of “start over”. To do this, scientists suggest in advance using robots to build up on the surface of Mars, the house, which would be able to protect people from radiation, and to provide the early settlers with all the necessary. In addition, the astronauts (for obvious reasons, the crew will be composed of both men and women) should arrive at the red planet with high-tech equipment, with which one could produce their own oxygen, water and food. Periodically here be delivered new reserves from the Ground, as well as new settlers.
However, the complexity of the implementation of this idea lies not only in the technical side of the question, at least, the development of science never stands still. Important role plays also the ethical question of whether to send astronauts to Mars considering the fact that they’ll never see the Ground. Many experts argue that the flight to Mars one way does not mean certain death for astronauts, this is just the beginning of something new. In addition, now there are volunteers who are willing to take such a dangerous journey in the name of science.
But in spite of this, some have large concerns about the colonization of Mars. Scientists have drawn a parallel with the colonization of America and the emphasis on social conflict that may arise in the colony the first Martian settlers and lead to unpredictable results up to the assassination, the local “coups”, “revolutions” and “wars”. In addition, social tension, which is inherent in any society people can be intensified by many other factors: prolonged exposure in a confined space during the flight, adaptation to Martian conditions, and so on.
