Expedition 10 Continues Maintenance Aboard the ISS

After enjoying a three-day holiday weekend aboard the International Space
Station, Expedition 10 Commander Leroy Chiao and Flight Engineer Salizhan
Sharipov tackled a busy schedule Tuesday.

They conducted maintenance efforts on the Russian Elektron oxygen-generation
system. They tried to troubleshoot gas bubbles in the plumbing of the
system, which shut down Saturday morning. Tuesday’s efforts were not
successful due to an equipment problem. Russian ground controllers are
assessing the situation. Also, controllers used the oxygen from the ISS
Progress 16 spacecraft to repressurize the Station’s atmosphere.

On the science front, the Expedition 10 crewmembers conducted a session with
a European biomedical experiment that is studying the effects on space
travel on the perception and process of memorizing orientation and location
in a virtual reality environment.

Chiao and Sharipov recorded their body mass and calf measurements for a
Russian biomedical assessment studying changes in the human body during
spaceflight.

In other activities, Chiao and Sharipov continued to unload cargo from the
ISS Progress 16 cargo craft and performed their daily exercise regimen.
