The six members of the Expedition 24 crew aboard the International Space Station were busy Thursday with maintenance and science activities.

The Russian crew members, Commander Alexander Skvortsov and Flight Engineers Mikhail Kornienko and Fyodor Yurchikhin, performed maintenance on the Treadmill Vibration Isolation System (TVIS). The TVIS is an important part of the exercise regimen aboard the station. Each crew member exercises for 2.5 hours daily to stave off the effects of long-term exposure to weightlessness.

Flight Engineer Shannon Walker set up an experiment that studies blood pressure decreases when the human body is exposed to microgravity. In order to increase the blood pressure to the level it was on Earth, salt is added to the crew s’ diet. To monitor this, blood pressure readings are performed at different intervals during the mission.

Inside the Japanese Kibo laboratory, Flight Engineer Doug Wheelock conducted maintenance on the Fluid Physics Experiment Facility for a study of the Marangoni effect, which is the flow of liquids caused by surface tension.

All six members of the crew participated in a periodic emergency fire drill. Once the fire drill was complete, the crew reviewed emergency procedures and participated in conferences with specialists on Earth.

Flight Engineer Tracy Caldwell Dyson cleaned the cooling loops of the spacesuits used for a series of spacewalks by Wheelock and Caldwell Dyson to remove and replace a failed pump module. All systems aboard the station continue to function well following the spacewalks.
