A study says a trip to Mars could cause Alzheimer to humans
In recent years, the development of space-faring robots, designed to replace many would-be astronauts, has prompted some to call for an aggressive return to manned space missions in order to maintain the vitality and wonder of space exploration. However, a new study indicates that sending robots out into space instead of humans might actually be the best way forward, after all.
According to a new study published in the PLOS One journal, galactic cosmic radiation can eventually lead to cognitive impairment. In the past, NASA has studied the potential effects of space travel on humans as it relates to cancer and other physical maladies, but this new study indicates that constant exposure to various forms of low-level radiation in space could result in serious neurodegeneration.
