The Deep-Space Radiation Challenge

Beyond the shelter of Earth's magnetic field, crews are exposed to a steady sleet of galactic cosmic rays and the sudden violence of solar particle events. This radiation raises long-term cancer risk and can damage the nervous system, and shielding against the most energetic particles is one of the hardest unsolved problems of sending humans to Mars.
