摘要

A fter the end of the Cold War, the range of threats facing our nation seemed limited and discernible. We could plan, prepare and, if necessary, preempt a potential threat. But the terrorist attacks on Sept. 11, 2001, and more recendy hurricanes Katrina and Rita, have demonstrated that our knowledge is limited and that our nation remains vulnerable to man-made and natural disasters. The value of space was again demonstrated during the Katrina relief effort. Without space, it might have taken weeks to fully respond to the crisis. For example, the Air Force's Defense Meteorological Satellite Program spacecraft revealed to emergency management agencies those communities that lacked electrical power. Commercial remote sensing companies provided high-resolution satellite imagery to relief organizations, which helped determine the extent of the damage in specific areas. And, our Global Positioning System (GPS) helped our response units navigate areas devoid of landmarks or signs of previous existence. Disasters like Katrina and Rita have helped us to appreciate space as a critical enabler. However, I still do not believe we have fully recognized just how important space is to our country.
