EYESIGHT AFFECTS IN SPACE

With the recent spacewalks completed and space station power systems now at optimal operative levels, scientific research continues with effects on eyesight over extended stays in space.

The Expedition 50 crew is continuing its investigation into vision changes and eye damage some astronauts have experienced after long-term missions in space. Living in the microgravity environment causes a headward fluid shift that may be causing pressure behind astronauts’ eyes resulting in visual and physical changes.

Two cosmonauts, Sergey Ryzhikov and Andrey Borisenko, and European astronaut Thomas Pesquet explored a possible solution to the upward fluid pressure. Borisenko donned the Lower Body Negative Pressure (LBNP) suit which pulls fluids down towards the feet. Ryzhikov and Pesquet then used an ultrasound scan and performed eye checks on Borisenko to determine the effectiveness of the LBNP suit.

On the station maintenance front, NASA astronaut Peggy Whitson installed vacuum access ports in the Harmony module. Commander Shane Kimbrough connected gas and water umbilical hoses in the Columbus lab module. He also updated supplies for the Human Research Facility that enables scientists to learn how astronauts adapt to living in space.
