Flight to Mars will shorten the life of the astronauts on 2.5 years
Source:
At present, humanity has almost everything you need in order to make the longest space mission in history — flight and Mars. In space you can get energy from the Sun, to get water, to replenish oxygen through artificial photosynthesis, and even to grow plants. The main issue for the future of the first settlers at the moment is cosmic radiation. And humanity just need to figure out how to protect the crew of a spacecraft from its effects.
According to the latest data, the flight to the red planet because space radiation will reduce the lifespan of the astronauts at least 2.5 years. This was reported by scientists in the framework held in Moscow conference "Aerospace and environmental medicine". In the study of the impact of space radiation on living organisms, the experts found out that the space flight duration of 2 years has katastroficheskie implications for human health.
"currently the calculations of total radiation risk over the entire life of astronauts after long-term (up to three years) missions to Mars in the period of maximum solar activity with different thickness protection radiation shelter made of aluminium. For a two-year duration of expedition to Mars and back, the total radiation a risk during the life of the astronauts, regardless of age, for the protection of a radiation shelter 20 grams per square centimeter will be 7.5% and the reduction in the average expectancy of life (SPG) — 2.5 years." — experts quoted by the news Agency "Interfax".
Data were obtained on the basis of indicators of standard spacecraft is a simple spherical shape and inside of it a standardized phantom model of the human body. The calculations also took into account the rapid removal of the ship to the orbit of Mars by means of the liquid jet engine and nuclear power propulsion.
