Harmony was unberthed from Discovery's payload bay at 9:35 a.m. EDT this morning, and the station's robot arm is slowly maneuvering the module out of the shuttle's payload bay and over to its attachment point on the side of the Destiny lab module. Spacewalker Doug Wheelock is working with the P6 thermal covers while Scott Parazynski continues with the task of disconnecting various fluid lines between the Z1 and P6 trusses in preparation for the P6 relocation later in the mission.

Wheelock just performed an examination of Parazynski's EVA suit to check for any contamination from ammonia crystals that leaked out of one of the lines Scott has been working with.

The station's robot arm attached Harmony to a port on the Dstiny lab module at a quarter before noon, U.S. Eastern time. Mechanical bolts were driven to make the final airtight connection between the new module and Destiny. Harmony will remain attached to the side of Destiny until a few days after Discovery leaves the station, when the Expedition 16 crew will then detach the Pressurized Mating Adapter #2, which the shuttle is currently docked to, and attached it to the end of Harmony. Three days later, the station's robot arm will unberth Harmony from the side of Destiny and re-attach it to the forward end of Destiny in the location where PMA-2 had been located.

Scott Parazynski and Doug Wheelock entered the Quest airlock at 12 o'clock to bring an end to the first EVA of the mission. They successfully conducted tasks to prepare for the P6 solar array retraction while the station and shuttle crews lifted Harmony out of Discovery's payload bay and berthed it to the side of the Destiny lab module.

Quest airlock pressurization began at 12:16 p.m. to mark the official end of today's EVA. Total spacewalk duration was 6 hours and 14 minutes.

Leak checks of the Harmony to Destiny interface are getting underway.

The crew is performing very well today, not just right on the timeline but a half hour ahead at times.

Airlock re-press was held up briefly so that Wheelock and Parazynski could perform some precautionary decontamination procedures following the minor leak of ammonia earlier in the spacewalk. There's no reason to think either of the spacesuits is actually contaminated, but flight rules dictate that decontamination procedures be followed whenever there is a leak observed.

The Quest airlock hatch into the space station was opened at 12:53 p.m. wheelock and Parazynski are in the process of stowing their EVA gear and rejoining their eight fellow astronauts on ISS.
