Choose Unmanned Space Exploration

Re “Uncertain Science in Orbit,” Feb. 5:

NASA should be directed to conduct only unmanned space exploration. It is cheaper, less complex and will not involve the loss of life. The ongoing Columbia accident investigation boards will come up with some safety recommendations for future space missions.

Eventually NASA will drift back into its pre-Columbia ways, there will be another catastrophic accident, and the cycle will repeat itself. The best solution is unmanned space flight.

How is it that less than a week after the Columbia disaster an inquiry is up and running, but almost a year and a half later the Bush administration is still dragging its feet over the Sept. 11 attacks?
