stomach and intestines might be most damaged organs to perform long duration space travel, in addition the astronauts might be affected by terminal illness as cancer, research suggests. Experts believe that the Intergalactic travel can significantly affect astronauts due to exposure to radiation. These trips can also impair bodily functions in the long term and make inefficient absorption of nutrients and to cause cancer.
In reaching this conclusion, the scientists studied a group of mice after exposure to low doses of iron particles electrically, charged the most damaging form of cosmic radiation. Atoms and molecules that carry an electrical charge, are known as ions. The study led by Kamal Datta, Center of research specialized NASA at Georgetown University in Washington DC, said that current technology is not yet possible to protect astronauts from heavy ions.
He said that short trips, such as on the Moon, do not generate a level of considerable damage, but a trip to Mars or more depth in the space to be longer if would create serious health problems.
Several groups of mice were used in the study, one is exposed to heavy iron ions (act like tiny bullets that move quickly), a few more to gamma rays (are forms of high frequency massless light) and a third group which was not subjected to any form of r adiacion. The Group of rodents exposed to heavy ions presented difficulty to absorb nutrients and cancerous polyps were formed and iron damaged DNA. The damage in all cases appear to be permanent.
