Wednesday saw the Expedition 58 crew explore the inner workings of the human body in space and maintain cooling systems aboard the International Space Station.

NASA astronaut Anne McClain spent all day setting up cooling gear inside the U.S. Destiny lab module and Japan’s Kibo lab module. She drained and refilled water pumps inside the Fluid System Servicer and the Internal Thermal Control System. The life support systems help cool the station’s atmosphere and dispel heat generated by electrical systems.

Microgravity’s impact on the human physiology was the focus of Flight Engineer David Saint-Jacques’ day. The Canadian Space Agency astronaut collected and stowed his breath, blood and urine samples for a variety of human research experiments. The research is supporting the long term-collection of human biological samples and observing bone marrow and blood changes.

Saint-Jacques also conducted ultrasound scans in the Zvezda service module for the Fluid Shifts study with assistance from Commander Oleg Kononenko and doctors on the ground. That research is seeking to reverse increased head and eye pressure that occurs in space.

Kononenko started Wednesday servicing Russian life support systems. The four-time station resident then spent the afternoon on more space research studying motion coordination, radiation exposure and crew psychology.
