The tether would extend far far out over a geosynchronous orbit, such that the centripetal acceleration is exactly equal to the force of gravity. Thus, it would be weightless on the ground, maximum tension at geosynchronous orbit, and an easy launching platform at its end. Also, it can be easily deployed by unrolling the tether in both directions simultaneously from the geosynchronous orbit.
