Foale and Kaleri spent much of this week packing up trash to be jettisoned from the International Space Station in an old supply ship to make room for a new Progress cargo craft. They packed the unneeded equipment aboard the ISS Progress 12 resupply vehicle and prepared it for undocking from the Station at 2:36 a.m. CST Wednesday. The next resupply vehicle, ISS Progress 13, is planned to launch at 5:58 a.m. Thursday from the Baikonur Cosmodrome in Kazakhstan. Progress 13 is scheduled to dock with the Station at 7:18 a.m. Jan. 31. The cargo includes fresh food, clothes, spare parts and other equipment
Following the discovery and removal of a leaky vent hose two weeks ago that was part of a window system in the U.S. Destiny Lab, the Station's air pressure has been steady. A replacement for the hose will be launched aboard Progress 13.
Also this week, Kaleri followed up his replacement last week of a liquid separation unit for the Russian Elektron oxygen generation system by replacing the electronics package associated with the system. The crew noted a rattling noise in an air filter component on the Elektron, and an additional pressure regulator for the Elektron will be added to the Progress 13 cargo to address that noise.
The pair also conducted several Russian routine medical evaluations this week and continued their regimen of exercise on a variety of pieces of training equipment.
Last weekend, Foale and Kaleri spent two days in the Russian living quarters of the Station in a test to gather data on pressures in sections of the complex. Foale and Kaleri floated into the Zvezda living quarters module shortly after 2 p.m. CST Jan. 16, closing several hatches behind them that divided the station into four sections. They reopened the hatches about 11 a.m. Sunday. Flight controllers in Houston and Russia monitored air pressure in the sections of the Station during the weekend.
