RELEASE : SS05-002
 
 
International Space Station Status Report: SS05-002
 
 
Midway through a six-month stay on the International Space Station, the Expedition 10 crew this week focused on routine maintenance, biomedical investigations and a software upgrade.

The software work was under way for much of the week and involved updates to more than 1.5 million lines of code in the onboard command and control computers. The software upgrade generally improves the operations of onboard computers and, through its updates, decreases by about 300 the number of workarounds or, Station Program Notes (SPNs), ground flight controllers must use.

Also this week Commander Leroy Chiao and Flight Engineer Salizhan Sharipov measured their cardiovascular systems and conducted routine mid-term physical evaluations.

Sharipov began preparing gear that will be used during the two crewmembers' Jan. 26 spacewalk. During the spacewalk, they will install a new work platform on the exterior of the Zvezda living quarters module, hook up a small robotic experiment and install other scientific gear on the Station's exterior. The first of two planned spacewalks for Expedition 10, it will be conducted from the Russian airlock using Russian spacesuits.

Formal preparations for the spacewalk begin Monday. The 4-1/2 hour spacewalk will be broadcast live on NASA Television, beginning at 1 a.m. EST Jan. 26. The spacewalk is expected to begin about 2:25 a.m. EST.

All Station environmental control and life support systems are operating well, including the Elektron oxygen generating unit. Though Saturday is planned as an off-duty day for the crew, flight controllers plan a reboost of the Station's altitude of about 3 statute miles (5 kilometers) using engines on the attached Progress cargo craft. The reboost engine firing will last almost 20 minutes.

Information on the crew's activities aboard the Space Station and future launch dates, as well as Station sighting opportunities from anywhere on the Earth, is available on the Internet at:
