Keith's note: In April 2015 the Planetary Society held an invitation-only "Humans Orbiting Mars" workshop wherein they unveiled their idea for a mission to Mars. At a quick press conference after the event (no media were allowed to attend the workshop) the Planetary Society promised more detail would be made public - later. Since then nothing but crickets. Well, it now looks like the Planetary Society Mars plan is now online - but only for a few weeks - then you will have to pay to read it. An article on the grand plan by Scott Hubbard will only be online here until 29 July 2015. I do not see any mention of this report's availability on the Planetary Society website. I am not sure how far a mission concept like this is going to get if no one can read the details. Given that most of these new space policy ideas have been semi-secret lately it would seem that the authors are not really interested in any meaningful public engagement.
