Station crew members moved Harmony from its temporary location on the left side of the Unity node to its new home on the front of the U.S. laboratory Destiny Wednesday morning. Disengagement of the first set of bolts holding Harmony to Unity began at 3:58 a.m. EST.
Expedition 16 Flight Engineer Dan Tani again operated the station's robotic arm. Working slowly and deliberately, he moved the 31,500-pound Harmony with the 1.5 ton PMA-2 at its outboard end. Canadarm2's base was attached to a power and data grapple fixture atop the Destiny laboratory.
Station Commander Peggy Whitson operated the common berthing mechanisms, first to free Harmony after Tani had grappled it with the arm, and later to drive bolts firmly securing it to the front of Destiny, the position PMA-2 had occupied for seven years.
Release of the bolts and latches holding Harmony to Unity was completed at 4:21 a.m. Driving of the final bolts to attach Harmony to its new home was completed at 5:45 a.m.
After its Wednesday move, Harmony is in position to welcome visiting space shuttles. It also will offer docking ports to the European Space Agency's Columbus laboratory, scheduled to arrive next month, and Japan's Kibo experiment module, to become a part of the International Space Station next year.
Spacewalks by Whitson and Tani are scheduled Nov. 20 and Nov. 24 to complete the outfitting of Harmony.
Harmony was launched aboard the space shuttle Discovery and temporarily attached to the Unity node on Oct. 27. Harmony adds 2,666 cubic feet of pressurized space to the orbiting laboratory.
