Curiosity and the will to explore certainly is a fundamental part of the human condition. But the human body has natural limitations that technology cannot overcome. While artifice can go a long way to making places suitable for the frail human form, it can only go so far. Manned space flight is extremely expensive, costing the US government, the primary investor in space technologies tens of billions of dollars every year, yet there remains no clear plan for humans to return to the moon, let alone Mars and the rest of the solar system. [1] Exploration beyond the solar system remains a pipe dream. The laws of physics likewise seem to make the possibility of human exploration beyond the solar system nigh impossible. Other stars are simply too far away for a human to reach. The reality simply is that manned space flight is too costly and will likely never find application beyond Sol.
