A Mars Mission's Greatest Challenge: Radiation
daSeiz writes "A New York Times article explores the possible effects of prolonged radiation exposure in deep space. Surprisingly, very little is known about the subject. We'll need to find innovative new ways of shielding spacecraft from fraction-of-lightspeed interstellar rubbish if we're ever to spend much time outside our own magnetosphere."
Sure, funnyman. Show me the calculations that show that a human being could survive exposure to radiation outside the van Allen belts.
The owls are not what they seem
if you want "No More Hiroshimas" then I say "You First. No More Pearl Harbors."
Unless, of course, they never made the trip.

I'm the Vice President of an engineering facility that does space stuff and I thought I'd take the time out of my busy schedule to explain the science behind this story.
Everyone knows about the Big Bang. When the Big Bang happened, all the planets were created and life began. These lifeforms then produced trash from their planets and dispelled it into space, much like we do with our garbage (where else do we keep it? under the 'ground'? *scoff*). This then causes all the showers of trash that we need to avoid when we go to Mars.
I believe the commonly held point of view in the scientific community is that most space trash is caused by life. For example, planets on the other side of the universe launch satellites which eventually turn up here and bombard our planet. But because they took so long to get here, they get dusty and are called meteors or comets. I think some scientists said once that Halley's Comet is a spaceship from the other side of the universe that is very dirty and some aliens wrote 'I wish my wife were as dirty as this' into the surface.
