I have read differant sources that think new plastic's will be used to cover the crew compartment for the MARS missions. There are also Ideas of surrounding a ship with water that blocks a lot of the rays. And there's the Ion Shield that's still in the Idea stage. He is right in that we are not ready right now. And Manned missions to Mars may have to wait till more research is done at a MOON Base. So lets get going to the Moon!

Why is radiation such a concern when they can dance on the moon with just their spacesuits?

I think the debilitating effects of micro-gravity is worse then the radiation. Or at least more insurmountable. I have read on several occasions that the lack of gravity results in bone/muscle loss which is often irreversible. This can cause many defects such as Arthritis and the like.

Why is radiation such a concern when they can dance on the moon with just their spacesuits? The length of exposure to the radiation hazards. On the moon they're there for a short period of time. While a trip to and from Mars would take much much longer and then the exposure would be built up over time and would start to cause problems. Think of these trips as the laser pointer beam. A quick beam in the eye won't blind you but a beam left in your eye for months on end will cause damage.

On one of the NASA sites they told about the different ideas for a Space Station, and originally a round station that spins was in the design, but was cancelled like many other ideas. Until we get the technology to create gravity we may have to build ships like the Babylon-5 TV series had, a rotating center along a weightless straight main frame. That will solve the Gravity problem.
