Space systems in constant earth orbit have both a speed and a range far greater than atmospheric ones. They can travel at orbital velocities in excess of 18,000 miles per hour and circle the globe in 90 minutes or so. While air-breathing vehicles cannot do nearly as well in relative speed, they share global reach as an attribute. They can go farther, faster, and with greater strategic effect than surface forces can. And increased space capabilities will only improve our range and reach.
Range is a spatial relationship.
It involves distance and reach. The responsiveness factor mentioned above has a spatial as well as a temporal dimension. Global reach achieved by the characteristic of range means that responsiveness occurs in space as well as time. Getting anywhere is as important as getting there anytime. More specifically, getting precisely there, in time, is the key to affecting events elsewhere in the world.
