London (CNN) -- You've answered the call for volunteers, signed up for the Mars trip and you are looking forward to boldly going to space, the final frontier, to explore a strange new world. But wait. Recent evidence from NASA's Curiosity rover mission to the Red Planet has revealed that astronauts on the round-trip would be exposed to high levels of radiation from cosmic rays and high-energy particles from the sun contained in solar storms. NASA says a Mars voyager would receive a radiation dose around 100 times the average yearly exposure on Earth. Along with all the other risks of spaceflight, this would clearly be bad for your health -- and it is proving difficult to find a solution.

"You end up with a constant electric field that can be enough that it actually refracts or deflects enough of the radiation from inside the magnetic cavity that you've formed to protect the astronauts ... enough like the @placeholder that they can survive."
