The Expedition 14 crew continued with preparations for a spacewalk this Thursday. Hatch opening is scheduled for 5 a.m. EST and the excursion will last about 6 hours. The spacewalkers have conducted leak checks and have installed lights and additional equipment on their Russian Orlan space suits.

The crew conducted its Orlan dry run Tuesday morning. Commander Michael Lopez-Alegria and Flight Engineer Mikhail Tyurin began preparing their Russian suits around 5 a.m. EST and donning their suits for a communications and systems test.

Lopez-Alegria and Tyurin will participate in their increment’s fifth spacewalk – a record for station crews. They will attempt to free a stuck antenna on the ISS Progress 23 docked to the aft end of the Zvezda service module. They will also check on navigation systems in preparation for the summer docking of a European cargo craft known as the Automated Transfer Vehicle.
