> HOUSTON - The Expedition 15 crew completed the first of three planned 
> spacewalks this week and prepared for the upcoming arrival of space 
> shuttle Atlantis to the International Space Station.
> On Wednesday, Commander Fyodor Yurchikhin and Flight Engineer Oleg 
> Kotov stepped outside the station and installed five additional 
> debris protection panels on the conical section of the Zvezda Service 
> Module, the area between its large and small diameters. The aluminum 
> debris protection panels are designed to shield the module from 
> micro-meteoroids.
> Also during the spacewalk, the cosmonauts relocated a Global 
> Positioning System (GPS) antenna cable. The cosmonauts moved the GPS 
> cable to assist the rendezvous and docking of the European Automated 
> Transfer Vehicle later this year.
> On June 6, Yurchikhin and Kotov are set to wear Russian spacesuits 
> again and install 12 additional protection panels on Zvezda. They 
> also will install a section of an Ethernet cable on the Zarya module 
> and a Russian experiment called Biorisk on the Pirs Docking 
> Compartment.
> During the second spacewalk, Flight Engineer Suni Williams will remain 
> aboard the station as the spacewalk choreographer, as she did this 
> week, advising and keeping the spacewalkers on schedule.
> Additionally this week, Williams packed science payload and personal 
> items she will bring with her when she returns to Earth at the end of 
> the upcoming STS-117 shuttle mission, scheduled for launch Friday, 
> June 8 at 7:38 p.m. EDT.
> Williams collected her fifth and final set of blood and urine samples 
> for the Nutritional Status Assessment, which measures physiological 
> changes in the human body during spaceflight. The samples are stored 
> at minus 80 degrees Celsius in the Minus-Eighty Laboratory Freezer. 
> The experiment will help researchers understand bone metabolism, 
> oxidative damage, vitamin and mineral status and hormonal changes and 
> how they relate to stress, bone and muscle metabolism. The results 
> should provide a better understanding of what happens 
> physiologically, and when it happens, to crew members on 
> long-duration space missions.
> Science activities on the International Space Station are coordinated 
> by NASA payload teams at Johnson Space Center, Houston, and Marshall 
> Space Flight Center, Huntsville, Ala. Marshall is the home of the 
> Payload Operations Center linked to Mission Control in Houston.
