NASA Animation of Dawns's visit to Vesta
A good example of interplanetary travel as it's done today.
Watch the months and years go by in the upper right corner of the screen as our probe travels through the solar system.
Slingshoting around planets and aided by an Ion drive, it's still a poky way to get there.
