The perception of object size in microgravity. Bansal, A. T., Jorges, B, Bury, N., McManus, M., Allison, R. S., Jenkin, M. R. M., & Harris, L. R. In 2022 Scientific Abstracts: The First Canadian Space Health Research Symposium, pages 1. 2022. abstract bibtex One of the most common, and most complex functions of the human brain is to perceive our own motion. Estimating how far we have travelled is a multisensory process, although the relative contributions from our different sensory systems in estimating travel distance is still unknown. Testing astronauts in microgravity not only allows us to parse out the contributions from the different senses more easily, but it can also inform mission planners and trainers about how our perception of travel distance might change in microgravity. Using VR, we tested astronauts' (n=12, 6 female) perceived travel distance 5 times: once before their flight, twice in space (upon arrival and 3 months after), and twice again when they returned back to Earth (upon reentry and 2 months after). Preliminary results show no differences between the astronauts' estimations of travel distance after arriving to the ISS, after 3 months in space, or when they returned to Earth. These findings not only provide insights into the sensory contributions involved in making travel distance estimates, but also indicate that there is no adverse effect of long- duration exposure to microgravity on perceived travel distance.
