The Expedition 63 crew serviced a variety of International Space Station hardware today ensuring research, power and life support systems continue operating in good condition. Heart research and team psychology studies also filled today’s science schedule.
Commander Chris Cassidy of NASA wrapped up science rack swap work that he began on Monday. He finished moving and reinstalling three advanced science facilities, known as EXPRESS racks, in three different lab modules. The rack exchanges will support future experiments being delivered on an upcoming Cygnus resupply mission from Northrop Grumman.
Afterward, Cassidy collected water samples from the potable water dispenser for analysis on Earth and on the station. The veteran astronaut also inspected U.S. module hatches and replaced pipes in the orbiting lab’s restroom, known as the Waster and Hygiene Compartment.
Three-time space station cosmonaut Anatoly Ivanishin strapped himself on an exercise bike this morning for an assessment of his cardiac activity in space. First-time space flyer Ivan Vagner assisted Ivanishin attaching sensors to the test subject and monitoring his activities during the hour-long test.
The Russian duo then checked battery temperatures and connections before studying how international space crews interact with mission controllers around the world. Ivanishin went on to set up advanced Earth observation gear while Vagner worked on power system diagnostics.
