Research into How Space Impacts Humans and Physics Continues













ISS - Expedition 58 Mission patch.

February 14, 2019

The three residents onboard the International Space Station today worked with a diverse array of science hardware. The trio continues to explore what living in space is doing to their bodies and helped scientists promote healthier humans in space and on Earth.

Astronauts have reported increased head and eye pressure during long-duration space missions. The Expedition 58 crew is researching that phenomenon today to help doctors reverse the upward fluid shifts that affect space residents.

One solution being studied is a special suit that draws fluids such as blood and water toward the lower body to prevent swelling in the face and elevated head and eye pressure. Astronaut Anne McClain tried that suit on today and Flight Engineer David Saint-Jacques used an ultrasound device to scan the activity. Commander Oleg Kononenko assisted the duo inside Russia’s Zvezda service module.

Afterward, McClain glided to the opposite end of the station in Japan’s Kibo lab module to work on the Two-Phase Flow fluid physics experiment. She set up and installed the research hardware inside Kibo’s Multi-purpose Small Research Rack. The experiment may enable engineers to design advanced thermal management systems for use on Earth and in space.

Saint-Jacques returned to biomedical studies today collecting and stowing more breath, blood and urine samples for later analysis. The ongoing research is helping scientists understand the long-term space impacts to bone marrow, red blood cells and the overall human physiology.

Saint-Jacques finally reviewed instructions to install a docking station on Friday for new cube-shaped, free-flying robots that will arrive at the station later this year. The Astrobee autonomous assistants may free up more science time for astronauts and allow mission controllers better monitoring capabilities.
