It’s barely 8 a.m. as Chris Carberry stands in the middle of a field in the early morning sunlight, shivering slightly. He’s waiting for Barack Obama, who is due to speak in about two hours. Obama volunteers are wary. Could Carberry be a researcher from the Clinton campaign? Or a dangerous nut? No, Carberry is a motivated man determined to see through his mission: to find out where each of the presidential candidates stands on Mars.
Carberry is the political director of the Mars Society, a nonprofit group that pushes relentlessly for human exploration and settlement of the red planet. He’s the point man for Operation President 2008, in which Mars Society members lie in wait for presidential candidates at campaign stops in the early primary states, then leap out to pop the question: As president, would you send a man to Mars?
