Recently, Ray Bradbury presented his testimony in front of the Aldridge Commission. His testimony relies primarily on an “aesthetic” argument—that the trip to Mars, and beyond, should not be about profit, or even about practicality, though those can definitely come along for the ride. Instead, expansion to Mars is the next step of discovery that has been given to us; a gift of the universe.
Pretty persuasive, I think, to us Mars Society types, but then again, we didn’t need convincing. I have to agree with Mr. Spudis that the American public won’t be so easily convinced, just based on my experience in talking to others. So it is important to push Mars not just on the Sir Edmund Hillary argument (”because it’s there”), but because Martian exploration will bring tangible benefits to humanity.
The remaining question is, what benefits are those? Comments are open for this one.
