As NASA plans to return astronauts to the moon and ultimately send humans to Mars, teams across the space agency are working to build solutions for protecting the travellers from harmful radiation.
Some teams are developing technology such as wearable vests and devices that add mass, and electrically charged surfaces that deflect radiation.
When NASA sends humans to the moon again, it would want them to stay there, unlike the Apollo mission 50 years ago. But long-time exposure to space radiation may raise health risks, including cancer. Developing solutions for shielding astronauts from space radiation is, therefore, very crucial.
