INTERNATIONAL SPACE STATION STATUS REPORT: SS06-053

HOUSTON - The three residents of the International Space Station spent a busy week unpacking, inventorying and stowing more than two tons of equipment and supplies left by the Space Shuttle Discovery

The week began with Christmas, a day off for the crew except for required maintenance and exercise Commander Mike Lopez-Alegria and flight engineers Mikhail Tyurin and Sunita Williams were back on their regular schedule Tuesday, waking at midnight CST and going to bed at 3:30 p m

Unpacking items delivered by Discovery took up part of each day during the week Crew members entered the new supplies and equipment in the Inventory Management System, a computerized, bar-coded tool to keep track of the voluminous material aboard the orbiting laboratory

Lopez-Alegria and Tyurin passed a milestone of their stay on the station on Tuesday -- it was their 100th day in space Williams came to the station aboard Discovery earlier this month She had an hour budgeted each day to familiarize herself with the station and adapt to life on board These unstructured hours are scheduled during new crew members' first two weeks aboard to get them used to the station and its activities

Scientific activities picked up again on the station since the departure of the STS-116 crew During the week, crew members worked on experiments analyzing heart function during long-duration spaceflight, measuring cosmic rays, and examining plant growth and changes in blood of long-duration spacefarers They also continued a Nutritional Status Assessment

Crew members also performed required station maintenance and did their daily 2 5 hours of exercise, designed to mitigate some of the negative effects of lengthy space flights

The next station status report will be issued Jan 5, or earlier if events warrant For more information about the crew's activities and station sighting opportunities, visit:
