NASA wants to find out why zero G impairs human eyesight
A previous NASA study proved that space can impair an astronaut’s vision, which is a huge problem if we want to start sending humans to Mars. That’s why the agency has launched a new study that aims to pinpoint the exact cause of “space vision” and to find a way to prevent or fix the issue. Under the leadership of principal investigator Christian Otto, NASA will “collect evidence to characterize the risk and define the [visual, vascular and central nervous system (CNS) changes]” in microgravity. In other words, the researchers will examine astronauts before they fly for the ISS, while they’re living aboard the space station and when they land after their expedition ends to determine the changes in their bodies.
