Space: The ever-changing frontier . . .

The June 2013 issue of National Geographic magazine (out now!) includes a graphic titled "Cosmic Journeys," an earlier version of which ran in an NGM special issue in 2009. This spring, I helped revise and update the content so it could be included in a yearlong series on exploration in honor of the Society's 125th anniversary. Doing so made me realize not only how far we've come, but also how much further we still have to go in exploring our universe. Will we one day live aboard star ships, boldly going where no man (or woman) has gone before? I certainly hope so . . .
