Space radiation is such a difficult problem to solve for engineers trying to figure out how to move humans around the near solar system. If astronauts on the ISS didn't have warning and protection against this, then they could be in some trouble. I once read a pretty credible article that some scientists were thinking in order to travel to Mars, we might have to drill tunnels into asteroids and manipulate the asteroid's orbit in order to both arrive at the target and shield themselves against radiation. It could work right?
