Two residents of the International Space Station ventured outside the complex Wednesday for a 5 hour, 38 minute spacewalk to reposition, deploy and relocate equipment and conduct a commercially sponsored activity.

With Flight Engineer Thomas Reiter inside to monitor systems, Expedition 14 Commander Mike Lopez-Alegria and Flight Engineer Mikhail Tyurin opened the hatch to the Pirs Docking Compartment airlock at 6:17 p.m. CST as the station flew over the Atlantic Ocean near the west coast of Africa. They wore Russian Orlan spacesuits for the 19th spacewalk conducted out of Pirs since it was mated to the Russian segment of the station in September 2001 during Tyurin's first flight as part of Expedition 3.
