ISS STATUS REPORT #07-4



SUBMITTED BY ARTHUR N1ORC - AMSAT A/C #31468

*International Space Station Status Report #07-4*
*9:30 p.m. CST Friday, Jan. 19, 2007*
*Expedition 14 Crew*

New supplies arrived at the International Space Station Friday night as 
an unpiloted Russian cargo spacecraft docked to the Pirs Docking 
Compartment.

With more than 2.5 tons of food, fuel and supplies for the station's 
Expedition 14 crew, the ISS Progress 24 automatically docked to Pirs at 
8:59 p.m. CST (5:59 a.m. Moscow time Saturday) as the station flew 220 
miles above the South Atlantic off the southeast coast of Uruguay. The 
24th Progress to visit the station launched Wednesday night from the 
Baikonur Cosmodrome in Kazakhstan.

Unlike its predecessor, Progress 24 linked up to the station after its 
automated rendezvous antenna retracted as planned in the final 50 meters 
prior to docking. On Oct. 26 the automated navigation antenna on the 
Progress 23 failed to retract. Expedition 14 Commander Mike 
Lopez-Alegria and Flight Engineer Mikhail Tyurin will conduct a 
spacewalk in late February to manually retract and tie down the antenna 
before the older Progress undocks from the aft port of the Zvezda 
service module in early April.

The crew will open the hatch to the new Progress overnight and 
deactivate the systems of the newly arrived craft before its cargo is 
unloaded over the next few weeks. Progress 24 holds 1,720 pounds of 
propellant for the Russian thrusters, 110 pounds of oxygen and almost 
3,300 pounds of spare parts, experiment hardware and life support 
components.

In addition to preparing for the cargo ship’s arrival, the Expedition 14 
crew worked this week on a variety of station maintenance tasks and 
science experiments. Lopez-Alegria and Flight Engineer Suni Williams 
reported what they ate and drank, and collected blood and urine samples 
as part of an experiment know as Nutrition. The experiment looks at how 
the human body processes nutrients in microgravity.

Lopez-Alegria replaced limited-life components in the Volatile Organic 
Analyzer (VOA), part of the Crew Health Care System. The VOA is a gas 
analysis system used to assess the levels of organic compounds in the 
station atmosphere, some of which could become harmful to the crew in 
high concentrations. The old components will be returned to Earth on the 
next shuttle mission.

Williams focused on work with lentil seedlings as part of an experiment 
called Threshold Acceleration for Gravisensing, or “Gravi.” The 
experiment uses a European Modular Cultivation System centrifuge to 
document the effects of varying levels of gravity on the development of 
plant roots with an eye toward growing edible plants for future, 
long-duration spaceflights.

Tyruin worked with a number of Russian experiments, including an 
instrumented workout on a stationary bicycle to collect data on ways to 
limit bone and muscle density loss associated with long-duration 
spaceflights.

All three crew members also spoke with experts on the ground planning 
the upcoming Expedition 14 spacewalks. Lopez-Alegria, Tyurin and 
Williams will begin on-board preparations for those spacewalks along 
with a fourth to remove the navigation antenna from Progress 23. The 
first three spacewalks by Lopez-Alegria and Williams are designed to 
continue outfitting the newly activated cooling systems for the 
station’s truss and to continue preparations for the relocation of the 
P6 solar array truss structure.

The next station status report will be issued on Friday, Jan. 26, or 
earlier if events warrant.
