John bersia raises a question regarding the economics of space exploration - how does william justify investing in space exploration when we have so many things we still need to learn abouy on earth?

Space program attracts the best minds and novel technologies emerge from this industry. These technologies also prove to be useful even in civilian and economic sphere here on earth. Exploring outer space actually helps us understand earth even better since the celestial bodies are all formed by the same universal forces.

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
