ISS Crew Completes Several Tasks Aboard the International Space Station on Wednesday, the Expedition Seven crewmembers completed several routine tasks. Commander Yuri Malenchenko conducted a photo survey of the Zarya Control Module docking port to which the Soyuz TMA-2 is attached. The docking ports are always checked after the arrival of Russian spacecraft. NASA ISS Science Officer Ed Lu checked out a defibrillator, which is done near the beginning of every expedition. Lu also took bacterial and fungal air samples in the station. In Star City, Russia, the Expedition Six crew is continuing post-flight rehabilitation and debriefing activities. Commander Ken Bowersox and NASA ISS Science Officer Don Pettit are slated to return to the United States later this month.
