Space: How Bad is the Radiation on Mars? – Radiation has made Human space travel almost impossible

[A friend of mine who is into science told me a few years ago the shocking fact that radiation in space is so bad that true planetary space travel is so dangerous as to actually be impossible. You would DIE from the radiation. A trip to Mars for example, would kill you. But amazingly, scientists are breaking through this and making headway and it seems you might even be able to arrive at Mars alive. Jan]
