It would actually requre more fuel to launch if the shuttle was overhead. <br /><br />The most important thing is that the plane of the ISS orbit and the Shuttle launch be precisely alaigned. As long as they are, with the shuttle in a lower orbit in the same plane it catches up automatically.<br /><br />It takes a day or two for them to get settled in orbit, get the machine running and prepared for docking anyway, so there's no super rush. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
