Tethers have to be carried into orbit same as maneuvering propellant. I think what most people are wondering is if the mass of the tether system is more or less than the mass of the propellant that would accomplish the same things.

        Depending on materials, the tether can be of negligable mass, compared to the effect. However... - alcaray - 9/16/2007 9:36:28 PM
        
        I recall that there was a partially-successful tether experiment conducted by a shuttle crew. - Jacob Samorodin - 9/16/2007 10:25:53 PM
        
        It's in the piece that Raoul linked. (n/t) - alcaray - 9/16/2007 10:31:06 PM
        
        Yes, I scrolled down and found it.... Thanks. (n/t) - Jacob Samorodin - 9/16/2007 10:34:41 PM
