(I) In science fiction, the worst threats to space travellers are large ones: asteroids, ravenous creatures, and imperial battle cruisers. (II) The journey time from Earth to Mars could be reduced from six months to less than six weeks. (III) In reality, though, the scariest menaces for humans in space are the tiniest: fast-moving elementary particles known as cosmic rays. (IV) On a long journey, these would give astronauts a dose of radiation serious enough to cause cancer. (V) Unlike most of the other challenges of venturing into deep space, which engineers should be able to solve, cosmic rays pose irreducible risks.
