|Expedition 10 Commander
Leroy Chiao and Flight Engineer Salizhan Sharipov completed another busy
workweek aboard the International Space Station.
Throughout the week, they unloaded
items that arrived last week aboard the ISS Progress 17 spacecraft on March
2. The Progress delivered 4,631 pounds (2,100 kilograms) of cargo, including
food, supplies, fuel, oxygen, air and water. It also delivered cameras and
lenses that will be used to photograph the thermal protection tiles of Space
Shuttle Discovery as the Return to Flight mission approaches the Station in
May or June. Chiao and Sharipov are keeping track of the transferred items
with the Station Inventory Management System.
Chiao and Sharipov set up tools and
cameras on Thursday for next week's repair work in the Quest Airlock. Their
task next week is to install a new heat exchanger in Quest, which should
allow resumption of U.S. spacewalks from the orbiting laboratory.
Earlier in the week, Chiao got behind
the controls of Robotic Work Station and moved the Station's robotic arm
into the desired position of Expedition 10's second spacewalk. The excursion
is slated to take place March 28.
On the science front, the crew
participated in the Advanced Diagnostic Ultrasound in Microgravity (ADUM)
experiment. In addition to studying the ability of astronauts in space to
conduct exams using this onboard medical device, the experiment may have
widespread applications in emergency and rural health care on Earth.
Sharipov is slated to perform
troubleshooting on the Elektron oxygen-generation system. It has operated
intermittently during the past week. There has been no impact to
replenishment of oxygen in the ISS
