Re: Colonizing Mars
I'ts a sad fact, but true. If we take nine months to get the people from Earth to Mars (a standard Holman orbit), the radiation dosage they would absorb would be prohibitively large. It wouldn't kill them outright, but could damage their immune systems, make them feel sick, and possibly lead to cancer. There is no way (currently) to afford enough shielding to protect them during the journey.
One way around this, of course, is to shorten the voyage. If we could make the Earth to Mars trip in under two months, that would be about a 80% reduction in total radiation load -- about the maximum dosage that would be "safe".
So then, how do we get the trip down to seven or eight weeks? Maybe thermal nuclear propulsion.
