Bush on virtually anything but I have to admit he might have a point about going to Mars. On 14 January 2004 in a speech at the headquarters of the US National Aeronautics and Space Administration NASA he outlined a number of goals for the future of that agency. Here s what he said about one of them With the experience and knowledge gained on the moon we will then be ready to take the next steps of space exploration human missions to Mars and to worlds beyond. Robotic missions will serve as trailblazers - the advanced guard to the unknown. Probes landers and other vehicles of this kind continue to prove their worth sending spectacular images and vast amounts of data back to Earth. Yet the human thirst for knowledge ultimately cannot be satisfied by even the most vivid pictures or the most detailed measurements. We need to see and examine and touch for ourselves. And only human beings are capable of adapting to the inevitable uncertainties posed by space travel. Not that I agree with him completely. I think he said the right thing but not necessarily for the right reasons. I don t know if given the enormous costs and risks associated with manned space flight especially over interplanetary distances satisfying some nebulous thirst to see and touch for ourselves is enough justification for huge expenditures of public money when we have so many unmet social needs on earth. I do think it might be a reason for spending private money but that s another matter. And I think he has it completely backwards about humans being capable .
