By most reckonings, the International Space Station is a massive effort of waste and time. It sits in an inconvenient orbit and therefore won't be a stopping point on our way back to the moon. The actual costs have skyrocketed beyond previous estimates and resulted in huge cutbacks in functionality. And a sizeable percentage of hard research conducted there -- like the effects of zero-gravity on the human body -- has already been performed on earlier space missions.
Here's one bold if unlikely plan to salvage the ISS: turn the thing into a spaceship.
