There's a lot of skepticism about that 2018 date.

  Coming from a lot of the people who have doubted reusable rocket engines...

    I don't think so. Engines have been used before. Rockets have been landed on their tails by many organizations. And I don't think too many people doubt SpaceX can go to Mars. The questions are over the date.

      Most spacex dates slip. Sure they are wildly optimistic but the end result is still much faster than anyone else.

        That's the point, though. They do miss most of their deadlines, and if they miss the 2018 date they're going to have to wait a few years for a comparable launch window.
