NASA plans to undertake a mission to Mars within the next 15 years. However, astronauts face potential eyesight issues linked to spaceflight-associated neuro-ocular syndrome (SANS), a condition that causes significant changes to the eye due to prolonged exposure to microgravity. Symptoms include optic nerve swelling, changes in eye shape, wrinkles on the retina, and altered focusing abilities. Despite years of research, the causes and preventive measures remain unclear, highlighting the need for further study as NASA prioritizes health risks associated with long-duration space travel.
In the next 15 years, NASA hopes to launch a mission to Mars, but a mysterious ailment linked to long space flights could jeopardize astronauts’ eyesight.
Spaceflight-associated neuro-ocular syndrome (SANS) emerges from prolonged exposure to microgravity, resulting in significant changes in astronauts' eyes, necessitating urgent research.
