The NASA Glenn Research Center is responsible for conducting programs utilizing various on-board propulsion technologies for a number of applications. These technologies include gridded ion thrusters, which offer performance benefits over other advanced chemical and electric propulsion systems for certain high energy earth orbital and deep space missions. Propulsion systems utilizing ion thrusters need to be brought to a high level of development to enable these missions. This requires both theoretical and experimental evaluation of long-life/high performance ion thrusters and ion thruster systems. Contractor personnel have been working in the area of electric propulsion research at GRC,and are well suited to support future activities of this type.

I have an earlier post today about this PR stunt in the aliens and UFO forum.
I like to think that it gives a more correct picture of what is going on rather than this babbling about ion engines being up to the taks of hauling crew to Mars or not,.
I will just say here that the simple idea that this rocket and any capsule it could carry could make the two-year trip to mars--and back, for the capsule--is a worse blunder than the air force's explanation of the Roswell crash incident being explained by some of their crash dummies.
Please remove yourselves from accepting what NASA feeds you!
Wow Illustronic, I thought you were much better informed about this stuff. A rock can survive radiation just fine. It's living organisms that have problems when it gets excessive.

Sunglasses shield me from dangerous UV radiation. Radiation is largely misunderstood and used by moon hoax people as their bread and butter reply to something they don't know anything about. There are lots of different kinds of 'radiation' it is not one thing in the same, but is does have that scary mystical moniker.
If radiation out there is so bad how are those bodies in space still there after billions of years?
Protecting astronauts from deep-space radiation is a major unsolved problem. Consider a manned mission to Mars: The round-trip could last as long as 30 months, and would require leaving the protective bubble of Earth's magnetic field. Some scientists believe that materials such as aluminum, which provide adequate shielding in Earth orbit or for short trips to the Moon, would be inadequate for the trip to Mars. Barghouty is one of the skeptics: "Going to Mars now with an aluminum spaceship is undoable," he believes.
As my NASA link suggests, it's still an unsolved problem. That article talks about plastic spaceships as a possible solution. At least they are thinking outside the box, but I hope they find a better solution than that.

Getting there is one thing keeping the radiation out is another issue . Wonder how they solved that problem ?
Do CMEs not result in proton events? I got the impression from this article they are related but maybe I'm missing something.

CMEs, not so much. Solar proton events are more serious.
But that article confirms the cosmic rays are the most dangerous as you said, because the standard NASA-type spaceship won't protect the astronauts from those.
This whole story is ironic because flares and CMEs are themselves sources of deadly radiation. CMEs, in particular, cause "proton storms." En route to Earth, CMEs race through the sun's outer atmosphere, plowing through the hot gas at speeds exceeding a million miles per hour. Protons caught in the path of a CME can be accelerated to dangerous energies.
No astronaut wants to encounter a swarm of high-energy solar protons.
