Astronauts Dan Barry and Pat Forrester successfully strung two 45-foot heater cables and installed handrails down both sides of the Destiny laboratory of the International Space Station today during a 5 hour, 29 minute spacewalk, setting the stage for the delivery of a large truss structure to the complex next year.
The cables would provide backup power to the S0 truss, if needed, in the unlikely event it could not be installed in a timely fashion on the station next spring as the centerpiece for a 300-foot girder, which will serve as the backbone for the orbital outposts external experiments, solar arrays and the future mobile base for the Canadian-built station robotic arm.
Barry and Forrester began their spacewalk at 8:42 a.m. Central time, and ended their final excursion outside Discovery at 2:11 p.m., completing the 26th spacewalk devoted to the assembly of the International Space Station, 24 of which were staged from the Shuttle, and the 68th spacewalk in Shuttle program history.
Other spacewalk statistics following today's activity include:
-- Total spacewalk time in Shuttle program history: 431 hours, 39 minutes. -- Total spacewalk time to assemble the ISS: 167 hours, 24 minutes. -- Total Shuttle spacewalk time for ISS assembly: 163 hours, 3 minutes. -- Total spacewalk time for the two EVAs on STS-105: 11 hours, 45 minutes.
While the spacewalk was being conducted, Expedition Three Commander Frank Culbertson and his crewmates, Vladimir Dezhurov and Mikhail Tyurin, continued loading the Leonardo cargo module on the station, which will be detached from the ISS Unity module Sunday and returned to Discovery's payload bay for the trip back home.
The astronauts and cosmonauts will begin an eight-hour sleep period at about 8 tonight Central time and will be awakened at 4:10 a.m. Sunday to begin the 10th day of this mission.
The two spacecraft are in excellent health orbiting the Earth every 90 minutes at an altitude of 250 statute miles. The next mission status report will be issued at about 6 a.m. Sunday, or earlier if mission events warrant.
