With the robotic arms of Endeavour holding the massive but weightless construct which is the nearly fully completed MMS-1 spacecraft steady, and Discovery once again in place to oversee the operation each of the four airlock units are slowly, ever so slowly moved toward what will be their final resting place on the outer hull of the MMS-1 spacecraft. Shortly before final positioning takes place astronauts in thrusters suits will disengage each airlocks docking adaptor and with a gentle push allow it to make its way to a fiery decent as it re-enter�s Earth�s atmosphere. With this action completed astronauts on the outer hull of the MMS-1 and their colleagues just inside it�s inter hull will oversee the final phases of the operation to move each airlock into its final resting place on the hull of the MMS-1.
