The Expedition 22 crew members of the International Space Station enjoyed the last of three light-duty days Wednesday as they adjust to their regular work schedules following nine days of joint operations with the crew of space shuttle Endeavour.

Flight Engineer T.J. Creamer examined Flight Engineer Soichi Noguchi’s eyes with an ophthalmoscope while conducting the PanOptic experiment. This procedure captures detailed images and video of the eye for study by experts back on Earth. Station Commander Jeff Williams examined the eyes of Creamer and Flight Engineer Maxim Suraev Tuesday.

Suraev and Flight Engineer Oleg Kotov transferred discarded items and trash to the docked ISS Progress 35 spacecraft. After it is filled, the unpiloted Progress will undock April 27 to deorbit then burn up in the Earth's atmosphere.

The crew also had several opportunities for Earth observation and photography. Among the sites suggested for photography was Storm Bay, Tasmania. With Charles Darwin aboard, the H.M.S. Beagle anchored at Sullivan's Cove in Storm Bay on Feb. 5, 1836. During the ship’s 10-day stay, Darwin made five trips inland to study the local geology.

Throughout the day, the crew members performed their daily physical exercise routines to counteract the effects of long-term exposure to weightlessness in space.

The station’s three Command and Control Computers continue to function well after flight controllers in Houston’s Mission Control Center isolated the issue that caused the units to switch their roles on Sunday. The station’s Mission Management Team met Tuesday to discuss additional work to be done on those systems to prevent the issue from recurring.
