        is assisting with the docking of the Space Shuttle Endeavour at Launch 
        Pad 39B. Muktarian is using a surveying instrument called a zenith nadir 
        plummet to properly align survey plates located both on the pad surface 
        and the mobile launch platform (MLP), which rests atop the crawler and 
        supports the Shuttle.  |
