Clark Lindsey has dropped in on the Mars Society conference, which is in DC this year, and has some first-hand reports, on Mike Griffin’s speech and the latest from Elon Musk and SpaceX.

I haven’t spent much time reading them myself, being too busy, but when I do later, I may have some thoughts.

One question I do have, though. Just how big does Mike think is big enough for a heavy lifter for a Mars mission? How many decades does he plan to put off developing the critical technologies of orbital storage and handling of propellants, and vehicle assembly?
