From Radiation to Isolation: 5 Big Risks for Mars Astronauts (Videos)

By Kasandra Brabaw, Space.com Contributor | January 7, 2019  “……..Most people know that being exposed to too much radiation can make you sick, but the levels of radiation we experience on Earth are nothing compared to those that astronauts would be exposed to on the journey to Mars. Space radiation is much more harsh and damaging than the radiation experienced by people living on Earth.

Even astronauts who live on the International Space Station, which sits inside Earth’s protective magnetic field, are exposed to 10 times the radiation they would if they were back on Earth, NASA officials said in a statement and series of videos from the agency’s Human Research Program.

Anyone who traveled through deep space would be at much greater risk from radiation exposure. Outside of Earth’s protective shield, radiation can increase cancer risk and damage a person’s central nervous system (which would cause altered cognitive function, reduced motor function and behavioral changes), NASA’s Human Research Program said. Other dangers of being exposed to such high radiation include nausea, vomiting, anorexia, fatigue, cataracts, cardiac disease and circulatory disease. …….https://www.space.com/42918-big-space-risks-mars-astronauts-videos.html
