Flight to Mars will shorten the life of astronauts to 2.5 years
At the moment humanity is practically all you need to make the longest space mission in history - the flight and the Mars. In space, you can get energy from the sun to produce water, restock oxygen with the help of artificial photosynthesis and even grow plants. The main problem for the future of the first colonists at the moment is cosmic radiation. And humanity just need to figure out how to protect the crew of a spaceship from its effects.
According to recent data, the flight to the red planet because of cosmic radiation will reduce the life expectancy of the astronauts at least 2, 5 years. This was reported by scientists at the conference "Aerospace and Environmental Medicine" held in Moscow. As part of the study the effects of cosmic radiation on living organisms, experts found out that the space flight duration of 2 years has katstroficheskie effects on human health.
"At the moment we calculated the total radiation risk during the entire life of astronauts after long-term (up to three years) missions to Mars in the period of maximum solar activity with varying thickness of the radiation protection seekers from aluminum. For the two-year duration of the expedition, flight to Mars and back, the total radiative one lifetime risk of astronauts, regardless of age of the fallout shelter protected 20 grams per square centimeter will be 7, 5%, and the reduction in the average of the forthcoming life expectancy (ALE) - 2, 5 years. "- cites experts news agency" Interfax ".
The data were obtained on the basis of indicators of the standard spacecraft simple spherical shape and located inside a standardized phantom models of the human body. The calculations also take into account the rapid excretion ship to Mars orbit by liquid jet engine and nuclear power propulsion.
