Yesterday SpaceX tweeted that it is intent on going to Mars by 2018.
There are some details, like the fact the the “Red Dragon” will use a propulsive landing, much like the way they land their Falcon primaries right now, and that it will ride aloft on the new Falcon Heavy, a derivative of the current Falcon 9 launch vehicle. Very exciting stuff. Elon Musk will divulge detail in September, so roll on the 9th month.
Till then, just get out and fly.
