Crew Completes Third Spacewalk

The third and final spacewalk of STS-112 came to a close Monday at 3:47 p.m. CDT (2047 GMT). Astronauts Piers Sellers and David Wolf continued work to activate and outfit the S1 (S-One) Truss, which was attached to the International Space Station on Thursday.

THIRD EVA COMPLETED

During the 6-hour, 36-minute excursion, they installed fluid jumpers that will allow ammonia coolant to flow between the S0 (S-Zero) and S1 Trusses. Other work on the S1 included: installation of more Spool Positioning Devices on ammonia lines; a test of the Segment-to-Segment Attachment System on the outboard end of the S1 in preparation for the arrival of future starboard truss pieces; and removal launch support brackets no longer required. They also removed and replaced the Interface Umbilical Assembly on the station's Mobile Transporter.

Supporting the spacewalk, which was the 46th conducted at the station, were STS-112 Commander Jeff Ashby, Pilot Pam Melroy and Mission Specialist Sandy Magnus and NASA ISS Science Officer Peggy Whitson. Melroy coordinated the extravehicular activity. Ashby operated the shuttle robot arm, and Magnus and Whitson were at the controls of the station arm.
