The Expedition 31 crew members living and working aboard the International Space Station on Friday worked on the maintenance of the systems aboard the orbiting laboratory and conducted a variety of biomedical research and science experiments.

Flight Engineer Don Pettit continued his work with the Amine Swingbed experiment, repairing a valve motor. The objective of the experiment is to determine the effectiveness of a smaller, more efficient system to remove carbon dioxide from the station’s atmosphere.

Pettit also participated in a session with the Sprint experiment, which measures the effectiveness of high-intensity, low-volume exercise training in minimizing the loss of muscle mass and bone density that occurs during long-term exposure to weightlessness.

Flight Engineer Andre Kuipers worked on the relocation of the ALTEA, or Anomalous Long Term Effects on Astronauts, Shield Survey hardware from the Destiny laboratory to the Columbus module. ALTEA provides an assessment of the radiation environment inside the station to better understand the interaction between cosmic rays and brain functions.

Flight Engineer Joe Acaba performed a checkout of the Crew Medical Restraint System, which is part of the Health Maintenance System.

Pettit, Kuipers and Acaba also had time to participate in a session with the Health Maintenance System Eye Exam, known as PanOptic. During the session, the crew members captured still and video images of their eyes for downlink and expert analysis.

Commander Oleg Kononenko and Flight Engineer Sergei Revin worked together on the Bar experiment, which looks at methods and instruments for detecting the location of a loss of pressure aboard the station.

Flight Engineer Gennady Padalka worked in the Russian segment of the station with Kononenko and Revin, performing maintenance and monitoring its systems.

Over the weekend, the station residents will continue to perform their daily physical exercise routines, enjoy some off-duty time and have an opportunity to speak with family members. They also will carry on with regular maintenance duties and ongoing scientific research.
