The Expedition 43 crew kicked off a new week by focusing on a number of biological experiments.

The crew participated in the Sprint study which evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone, and cardiovascular function in crew members during long-duration missions.

Crew members also took part in Ocular Health checkouts as scientists search to better understand the vision changes some astronauts experience during spaceflight. They also collected samples for the Microbiome experiment which investigates the impact of space travel on both the human immune system and an individual’s microbiome.

Station commander Terry Virts did some troubleshooting on the Japanese airlock in preparation for the upcoming Robotics Refueling Mission-2 (RRM-2) operations. RRM-2, a joint study between NASA and the Canadian Space Agency, investigates satellite repair and servicing techniques in space. Operators on the ground use the station’s special purpose dexterous manipulator, better known as Dextre, on the end of the Canadarm2, for fine robotics manipulation. Engineers are looking to determine whether it’s possible to refuel satellites and test electrical connections robotically.
