As Flight Engineers Fyodor Yurchikhin and Mikhail Kornienko cleaned up after Tuesday morning’s spacewalk, Flight Engineers Doug Wheelock and Tracy Caldwell Dyson prepared for an August 5 spacewalk.

After a successful six-hour, 42-minute spacewalk Tuesday morning Yurchikhin and Kornienko reconfigured tools, the Pirs docking compartment and the Zvezda service module’s transfer compartment. They outfitted the Rassvet module’s Kurs automated rendezvous system, installed cables and replaced a video camera during their expedition’s first spacewalk.

The August 5 spacewalk will take place outside of the U.S. Quest airlock. Caldwell Dyson and Wheelock reviewed procedures Friday and set up tools they will use to install a power and data grapple fixture on the Zarya module. The grapple fixture will extend the station robotic arm’s reach and increase a spacewalker’s capabilities during assembly. They also will install a power cable to prepare for the upcoming installation in November of the Permanent Multipurpose Module during STS-133.

Flight Engineer Shannon Walker detached measurement units from the Cell Biology Experiment Facility inside the Kibo module’s Saibo rack. The Saibo rack provides facilities to experiment with and store biological samples. Walker also assisted Caldwell Dyson and Wheelock with their procedure review and participated in a spacewalk conference with ground specialists.

Commander Alexander Skvortsov, along with his crew mates, continued with his daily exercise regimen. The orbital laboratory’s exercise equipment includes two treadmills, an exercise bike and a resistive device that helps counter the long-term effects of microgravity.

2010 International Space Station Calendar

NASA is offering a 2010 calendar that describes the work being done on the International Space Station and gives information about the crews that have lived there. The calendar contains photographs taken from the space station and highlights historic NASA milestones and fun facts about the international construction project of unprecedented complexity that began in 1998. (Please Note: To print this large calendar on 8.5 by 11 paper, printer may need to be set on a "shrink to printable area" option.)
