Crew Concentrates On Station Maintenance
The Expedition 19 crew focused on maintenance Monday aboard the International Space Station.
Commander Gennady Padalka performed routine maintenance of water tank valves inside the Zvezda service module, and he did preventive maintenance on the ventilation system in the module. He performed a periodic purge of the Elektron oxygen generation system. Along with Flight Engineer Michael Barratt, Padalka also spent time orienting himself to his new surroundings aboard the orbiting complex.
Wakata performed the daily flushing of the station's Potable Water Dispenser using iodinated water to combat the growth of microbes in the device. He also set up the U.S. Sound Level Meter and performed an acoustic survey of the station, the data from which he later downloaded to controllers on the ground.
All three crew members performed their regular daily exercise to combat the effects of prolonged exposure to microgravity.
