The schedule is as follows:

• November 9: Spacewalk to configure Harmony
  
• November 12: PMA-2 relocation from Destiny to Harmony
  
• November 14: Harmony/PMA-2 relocation from Unity to Destiny
  
• November 20: Spacewalk to configure Harmony
  
• November 24: Spacewalk to configure Harmony

Having exited the ISS at 3:54 a.m. CST, the two worked to:

• disconnect the Station to Shuttle Power Transfer System (SSPTS) and other power and data cables connecting PMA-2 to Destiny;
• remove a crew equipment translation aid (CETA) light;
• demate connectors on the side of Destiny to prepare for the later installation of fluid line trays to run coolant out to Harmony;
• continuing power connections begun during STS-120 to Harmony;
• retrieve a signal processor and failed electrical circuit box; and
• remove the cover, known as the "shower cap" from the end of Harmony's common berthing mechanism, where PMA-2 will be connected.

Pressurized Mating Adaptor-2 (PMA-2) was moved from the front of the U.S. Destiny lab to the Harmony node early on Monday, clearing the way for Harmony's relocation to its permanent home.

Harmony, with PMA-2 on its outboard end, is set to be moved on Wednesday from its position on the Unity node to the front of Destiny.

PMA-2, which is where space shuttles have docked during recent missions, was originally attached to the lab on February 12, 2001 during Atlantis' STS-98 mission, which also brought Destiny to the ISS.

Disengagement of the first set of bolts holding PMA-2 in place began about 3:35 a.m. CST, initiated by Peggy Whitson working in Destiny. Release of the final set of bolts was completed at 4:02 a.m. PMA-2 was separated from Destiny at 4:12 a.m.

Dan Tani maneuvered the 1.5 ton PMA-2 with the station's robotic arm away from the lab, then to a point below Destiny, pausing for a camera survey of its mating surfaces. He then moved PMA-2 to the station's port side and toward the outboard end of Harmony and its pre-install position.

Harmony is now in position to receive the European and Japanese science labs to be added to the International Space Station.

ISS Expedition 16 crew members moved Harmony from its temporary location on the left side of the Unity node to its permanent berth on the front of the U.S. Destiny lab on Wednesday morning. Disengagement of the first set of bolts holding Harmony to Unity began at 2:58 a.m. CST.

Flight Engineer Dan Tani operated the station's robotic arm. 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.

ISS Expedition 16 commander Peggy Whitson and flight engineer Dan Tani wound up a 7-hour, 16-minute spacewalk to outfit the Harmony node in its new position in front of the U.S laboratory Destiny at 11:26 p.m. CST Tuesday.

They completed their scheduled tasks and accomplished three "get-ahead" jobs during the spacewalk, which began about 50 minutes early.

Much of the spacewalk was devoted to work with the Loop A fluid tray. The 300-pound, 18.5-foot tray was moved from its temporary position at the center of the station's main truss, to the Destiny Lab, atop the starboard avionics tray.

Tani and Whitson released the fluid tray and then moved it to Harmony by means of a relay technique, where one would move ahead of the other, attaching tethers to be ready to receive the tray, then the other moving farther forward to take the next handoff.

Once they reached the installation point they bolted down the tray, then hooked up its six fluid line connections.

As the spacewalk wound down, Tani and Whitson both worked on connection of Station to Shuttle Power Transfer System cables to the Pressurized Mating Adapter-2 (PMA-2), one of their three get-ahead tasks.

ISS Expedition 16 crewmembers Peggy Whitson and Dan Tani completed a 7-hour, 4 minute spacewalk at 10:54 a.m. CST on Saturday, concluding the external outfitting of the Harmony node in its final docked position in front of the Destiny lab.

The spacewalkers accomplished all of their scheduled tasks, including a late-added look at the starboard Solar Alpha Rotary Joint, and did some get-ahead work as well. The spacewalk was otherwise similar to the one they made on November 20.

As had happened during last Tuesday's spacewalk, much of Saturday's outing was devoted to installing a fluid tray that allows coolant to flow out to Harmony. The 300-pound, 18.5-foot tray was moved by Whitson and Tani from its temporary position on the station's main truss, to Destiny, atop its port avionics tray.

Whitson also removed a thermal cover from the starboard centerline berthing camera system and eight launch restraints from its latch petals. The camera and petals will help dock and initially attach ESA's Columbus laboratory, enabling bolts to be driven to secure it to its permanent berth during the STS-122 mission next month.

Whitson also installed the last remaining connection for the Station to Shuttle Power Transfer Power System.
