Fluid buildup is causing astronauts' vision to be impaired after stays in space

This has real implications for a trip to Mars. Astronauts who have spent less time in space than that trip would require are reporting degraded vision.

Based on the high-resolution orbit and brain MRI scans taken of their 16 astronauts, the team found that the long-duration astronauts had far higher orbital CSF volume – CSF pooling around the optic nerves in the part of the skull that holds the eye. They also had significantly higher ventricular CSF volume, which means they had more CSF accumulating in the cavities of the brain where the fluid is produced. “The research provides, for the first time, quantitative evidence obtained from short- and long-duration astronauts pointing to the primary and direct role of the CSF in the globe deformations seen in astronauts with visual impairment syndrome,” says Alperin.
The results were presented at the annual meeting of the Radiological Society of North America in Chicago this week (here’s the abstract), and have yet to be peer-reviewed, so we have to wait for the results to be replicated by an independent team before we can know for sure that this is the answer.
But even if this, or NASA’s original hypothesis turns out to be more accurate, we still have a big problem on our hands. Very few astronauts have spent more than a full year in space, and astronauts are already facing at least 18 months in space to get to and from Mars and that’s if they flew home immediately after arriving – if we want to think about colonisation or extended stays on Mars, we’re going to have to consider blindness as a potential complication.

We need to develop artificial gravity while in transit.

Requesting refund on my Mars ticket.

I suspect this is an issue with prolonged periods of microgravity. People wouldn't have these issues from staying on Mars. However, we do need to develop spacecraft that rotate to create gravity to live with for the journey to Mars.

Ship a Ferris wheel piece by piece to orbit, assemble and enclose it, attach booster rockets to it and ignite them to cause the Ferris wheel to spin. Boom! Artificial gravity!

Shoot mizzoukills to the sun, boom no more sun.

Space is just water.
Earth is flat.
Contrails do not exist but chemtrails do.
MK Ultra controls you.
Fluid around the eyes? This is just some CIA misinformation scheme to distract us from the lizard people moving into the big hole at the north pole.
Wake up people.

This is God's way of telling us not to frick with the way things are. He's already angry we went to the moon.

There is a surgical procedure to shunt excess CSF to the abdomen and relieve pressure. I wonder if that would be a feasible fix.

Problem is that shunt drains by gravity. Problem with the astronauts has more to do with gravity affecting the normal flow of CSF.
