That certainly seems a solid prospect. Of course, if we get some new kind of fuel cell, then 8/10 years whatever it is to Saturn now, could be dramatically reduced to such a point that a percentage of humans would take that trip. I think that the 18 months trip to Mars there and back (with the 3 month wait in between for optimum orbit position) is a reasonable amount of time for a human to travel to and from another planet . I think a journey to Saturn right now, at some 10 years (guessing) one way, would be a chunk that 99.9 % of humans would not take, even if we could safely do it........Dependant on us not blowing ourselves up, of course.
