Integrated Modeling of Microgravity-Induced Visual Changes

Astronauts are returning from space mission with changes to their vision. Understanding these changes has been challenging, since microgravity produces changes within the body that are impossible to replicate on Earth. One approach to understanding these changes is to use numerical modeling. In April 2014, our research team conducted research on the short-term effect of microgravity on the eye and surrounding structures. Subjects flew aboard a specially designed aircraft that was able to generate multiple periods of ~15-25 seconds of microgravity by flying a parabolic flight pattern. During the periods of microgravity, the research team acquired eye data from the subjects. Our results show that even short periods of microgravity produce measurable changes in the eye, and these data are being used to build and validate the numerical model of the eye. This work was a coordinated effort between the research team from the Geisel School of Medicine at Dartmouth College, the engineering firm Creare Inc., and the crew at the Reduced Gravity Office at Johnson Space Center. Students from the NHIMBRE program participated in the flight program.
