Time, distance and shielding – a radioprotective paradigm for Earth and beyond
Humans are preparing to embark on journeys further than they have travelled before, to expand our knowledge of what lies beyond our home planet. This will be no easy task, with only a handful of astronauts ever having been beyond the protective bubble surrounding our planet, and only briefly during the Apollo missions. This bubble is known as the magnetosphere and is the veritable force field which protects us from the harsh radiation environment of space and without it, life would not exist.
