We figured out some decades ago that I could send you or I can send a robot to this destination. I'm all for people in space, but to accomplish scientific goals, the robot can live off a sunlight and you can't. Robot is not going to cry because we ran out of money and we can't bring it back. You don't see this happening in the near term. Correct. Unless there's a geopolitical force operating, such as what happened with Sputnik. But would that be China says, Leica memo saying they want to put military bases on Mars. We're there in 12 months.
