HOUSTON - All plans are go for the second spacewalk of shuttle mission STS-130 at 8:09 p.m. CST, resuming the integration of the International Space Station's new Tranquility module. The crew members from the station and shuttle Endeavour also have learned they'll have an extra day on orbit together.
The crew members on board space shuttle Endeavour were awakened at 3:15 p.m. with "Too Much Stuff" by Delbert McClinton, played for Mission Specialist Stephen Robinson, who will be the intravehicular crew member for today's spacewalk.
Spacewalkers Robert Behnken and Nicholas Patrick spend the first part of the spacewalk connecting two ammonia loops, with two lines in each loop, from the Destiny module to Tranquility, hooking the new module to the station's cooling system, and open one of those loops to initiate cooling of the module. Then they'll install thermal covers on Tranquility's keel pin and trunnions, to prevent condensation inside the module, outfit the nadir docking port of Tranquility for the relocation of the cupola module, and install handrails. The spacewalk is scheduled to conclude at 2:39 a.m. Sunday.
Station Commander Jeff Williams and Flight Engineers Soichi Noguchi and T.J. Creamer, Pilot Terry Virts and Mission Specialist Kathryn Hire will continue outfitting Tranquility's interior, including setting up the ventilation system and configuring racks
Early Saturday morning the crew members outfitting Tranquility were unable to install a center disk cover on the module's outboard docking port due to interference with the cover's attach mechanism from hardware inside the cupola; that cover protects the docking interface from debris and temperature extremes when there's no module attached to it. The planned depressurization and grappling of the cupola at the end of the crew work day has been deferred to permit troubleshooting of that situation.
Mission managers today approved adding an extra day to the flight. That day, which will be a new Flight Day 11 beginning Wednesday afternoon, will be used to relocate two Water Recovery System racks, the Waste Hygiene Compartment and the Oxygen Generation System into Tranquility. Those relocations were on hold pending the repairs conducted earlier in the flight, and enough run time on the system to generate needed samples for return to Earth for analysis.
Endeavour's landing now will occur Sunday night, Feb. 21.The next shuttle status report will be issued at the end of the crew's workday, or earlier if warranted.
