A University of Nevada, Reno engineering project is headed into orbit this week as astronauts aboard the International Space Station prepare to test a virtual reality vision system designed to study how spaceflight affects the human eye.
The system, developed by computer science and engineering professor Alireza Tavakkoli, will be used during scheduled test sessions on April 22 and 23. Four astronauts will participate in trials using a VR headset-based platform to monitor changes connected to Spaceflight Associated Neuroocular Syndrome (SANS), a condition observed in astronauts after spending time in microgravity.
SANS is associated with changes to the optic nerve, optic disc, and retinal shape, all of which can impact vision. On Earth, those conditions typically require large and specialized imaging equipment. Tavakkoli’s system aims to provide a lightweight alternative suitable for use in space.
The experiment will collect medical data during roughly 30-minute sessions with each astronaut. Researchers plan to compare in-orbit findings with NASA’s existing astronaut medical database in a later phase, pending agency approval.
The ISS received the device from a Cygnus XL cargo spacecraft, launched April 11 from Cape Canaveral, and arrived at the station two days later. Additional testing will happen throughout the year, including sessions on June 18–19, August 28, and November 2.
The research supports NASA’s Artemis program goals for human presence on the Moon and missions to Mars. He also noted potential applications on Earth in remote or underserved areas where advanced ophthalmology equipment is not readily available.
The project received its funding through a $100,000 NASA EPSCoR award, part of a program designed to expand space-related research capabilities in participating states.
