Journey to Mars Could Mean Major Astronaut Health Woes

-Source-Newser- A study funded by NASA in a bid to determine what effects a journey into deep space might have on the health of astronauts has uncovered some startling possibilities for those brave souls who might one day venture to Mars. Per CNN the findings out of Georgetown University Medical Center suggest that the sort of radiation to which such travelers would be exposed has the potential to cause major intestinal issues including cancer. Its called galactic cosmic radiation or GCR and consists of so-called heavy ions that were protected from by the magnetosphere that surrounds Earth. Deep in space as well as on Mars there is no such protection and scientists say there is no way yet known to prevent exposure with shielding or medications. Per Inverse the study bombarded mice with doses of ionizing radiation that mimicked whats found in deep space. Researchers found that long exposure permanently altered the gastrointestinal tracts of the mice in a way that caused them to lose their ability to absorb
