I like that the Wall Street Journal pays attention to science issues.  

I think the solution to the radiation problem between here and Mars is, in part, a space elevator.  If you decrease the cost of launch you can increase the mass you send, which means you can send more shielding.  

Alternatively, you can make shield that astronauts can wear on their heads.  Nice lead ones would be particularly stylish.

A little confusing.  I thought the end of the paragraph that starts "to test the neural effects" was referring to residents of Colorado.  ;-)
