This month NASA Tech Talks is proud to bring you Dr. Tyson Brunstetter to discuss “Spaceflight Associated Neuro-ocular Syndrome (SANS) and its risk to NASA astronauts”.

First discovered in 2005, Spaceflight Associated Neuro-ocular Syndrome (SANS) is a unique condition detected in 70% of astronauts during long-duration missions. SANS is associated with vision shifts and anatomical changes to the eyes and brain which present risk to crewmember vision, cognition, and mission effectiveness. NASA considers SANS mitigation to be a top priority, especially for extended-duration missions to Mars where early returns are impossible. This NASA Tech Talk will discuss the history of SANS, how it is measured and diagnosed, its risk to astronauts, and how it might be mitigated as humans prepare for interplanetary travel.
