Eye Research, Treadmill Servicing Keeps Astronauts Busy on Station

Astronaut Engineer Raja Chari works on a biotechnology study

NASA astronaut Raja Chari works on a biotechnology study that may advance technologies for use in space and in extreme environments on Earth.

On March 8, three astronauts worked throughout the day continuing to research how living in space affects eye structure and visual function. NASA Flight Engineers Raja Chari and Kayla Barron were assisted by ESA (European Space Agency) astronaut Matthias Maurer in the Kibo laboratory module to help doctors understand why some astronauts have reported vision issues in microgravity and after returning to Earth. Results may help doctors develop treatments for eye conditions experienced by astronauts and Earthlings.

Meanwhile, NASA Flight Engineer Tom Marshburn spent the day working in the Tranquility module servicing the COLBERT treadmill. He started with a visual inspection before aligning components on the exercise device to ensure it remained centered inside Tranquility. COLBERT was delivered to the orbital lab over 12 years ago aboard space shuttle Discovery.
