International Space Station Status Report: SS07-03

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 on Friday 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.
