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. Continue reading
Radiation risk for astronauts (radiobiological rationale)
The book covers a fairly wide range of materials concerning the sources of cosmic rays affecting astronauts in the implementation of interplanetary and orbital space flight, the quantities of the doses, the reactions of individual systems and the whole organism of animals and humans, and changes its stability when the complex character of radiation exposure in space.
The results of a 14-year experiment on a large lot dogs with simulation values of the doses and nature of dose distribution in time, which will affect astronauts during the flight to Mars. The considered models of formation of radiation damage in the hematopoietic system and the level of the organism during long exposures with varying dose rate, and the model of radiation mortality rate of mammals, describing accelerated aging and the changing age-specific mortality rates in a dose-and dose rate radiation exposure.
The book presents the algorithms and results of calculations of the radiation risk in the process of interplanetary and orbital missions throughout the life of astronauts, as well as data on possible sacramentoa life expectancy. The new approaches to the regulation of radiation exposure and justifies the new lower acceptable dose to astronauts during flights and during the whole professional activity. Continue reading
100 kilometers above the Earth’s surface (according to the international standards space begins at this altitude), speed – kmh 4000, which is 4 times the speed of sound, so it looks like a tourist flight into space, which you could see in sci-Fi movies or dreamed about since childhood.
Now the dream to see the immensity of outer space has already become a reality.
Who are those 5 people who first saw the Galaxy, read the article. We will also talk about the details of the flight and to quote the impressions of space explorers.
Space tourists – Dennis Anthony Tito
