Interplanetary Spaceships

There's increasing talk of humans flying into deep space.  Dennis Tito apparently proposes sending two people around Mars in a Dragon capsule.  SpaceX talks about using a modified Dragon-- or perhaps tethering two Dragons together-- to settle Mars.  The Obama administration wants to send a crew on a months long trip to an asteroid in the Orion capsule.

Let's get real.  An interplanetary spaceship that will support a crew for months or years will have to be something the size of ISS or larger.  That's the only way to get back a crew that is physically and emotionally healthy.
