NASA astronaut and One-Year crew member Scott Kelly gathered hardware today for the start of the Fluid Shifts experiment. For the experiment on Tuesday, both Kelly and Russian cosmonaut Mikhail Kornienko will don the Russian Lower Body Negative Pressure (Chibis) suit and undergo ultrasound measurements. Fluid Shifts is a joint NASA-Russian experiment that investigates the causes for physical changes to astronaut’s eyes. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

Meanwhile, NASA astronaut Terry Virts worked today to prepare the Multi-Purpose Small Payload Rack (MSPR) and Thermal Container to enable the ground to perform additional data collection in advance of the Cell Mechanosensing-3 experiment, launching on SpaceX-7. ESA astronaut Samantha Cristoforetti took samples for the Microbiome experiment which investigates the impact of space travel on both the human immune system and an individual’s microbiome, the collection of microbes that live in and on the human body at any given time.

Virts and Cristoforetti also gathered tools inside the station’s Quest airlock for upcoming work on one of the U.S. segment’s spacesuits.

Today, the Russian Federal Space Agency (Roscosmos) announced they will provide an updated vehicle launch and landing schedule by June 9.

Crew Begins New Week With Focus on Biological Studies

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.
