![]() See, unlike us, astronauts never get to rest their brains in lower pressure. “So, we now think this mild but persistent pressure may be the thing that’s stimulating remodeling the eye and causing the visual impairment,” Levine says. Levine says space flight doesn’t cause pressure to be much higher than it is when you or I are standing up. Remember, they’re testing the hypothesis that pressure inside the brain at zero gravity is so high it damages the eyes. ![]() Most important for this research, he had a needle in that port in his head monitoring the pressure in the fluid surrounding his brain. “I enjoyed each and every rotation we did,” he said. Trent Barton, a lymphoma survivor from Dallas, went on the wild trip high above the Texas-Mexico border. Why? Because these cancer survivors have ports in their brains – ports once used to deliver chemotherapy – that now make testing the pressure inside their heads easier. These voyagers were all cancer survivors. Instead of sending people to the International Space Station, he’s using those fast swoops and dives of the plane as a chance to replicate the zero gravity experienced in space.Īnd there’s another big difference between these test subjects and the astronauts who have the vision problem. This hypothesis, that high pressure inside the brain is damaging the eyes, is what Levine was testing. “And when they’ve come back down to Earth, it looks for all the world like the pressure inside the brain is too high.” “One of the biggest medical problems in the last decade of manned space flight has been the understanding that astronauts on the International Space Station are losing their vision,” Levine explains. The goal? Figure out what’s behind a vision problem that affects astronauts. On the flight last week, Levine monitored the parabola-shaped trajectory of the NASA plane from a safe distance.
