Has a solution been found yet?

Well The real question is if this Fluid buildup also happens on Mars, where there is some form of gravity vs the "freefall" lack of gravity on the ISS.
Ofc the issue still persists considering a journey to mars takes alot of time. Havent read anything new about this though.

Fuck it's such a shame there's no gravity on Mars. If there were just a little bit of gravity to keep CSF from pooling in the head this would be a non-issue. Why does god hate us bros

"John Phillips, who spent time on the International Space Station (ISS) in 2005, brought his sudden bouts of blurry vision home with him, and during his post-flight physical, NASA confirmed that his vision had gone from 20/20 to 20/100 in just six months"

If only there was some method of creating artificial gravity, but that's science fiction. Oh well. I guess we should all stay here safely on this prison rock, fellow goyim.

If only we could do grade-school arithmetic and predict that we will see a one-third reduction in fluid buildup on Mars compared to zero gravity if there is a first-order relationship.

Sending anything other than autonomous robots to Mars is stupid. Humans are way too fragile and unreliable when Boston Dynamics robots are an option.

A human being is still the most versatile robot available. High upkeep, but absolutely outclasses any drone and makes all drones around it much more effective.

Extremely flawed, it's pretty embrassing you decided you could roll this shitty take out even on /sci/

I suppose you think in 1/3rd gravity, 1/3rd of objects would rest on the surfaces

>all known concerns, see "High upkeep."
The entire drone paradigm is flawed. It revolves around sending a one-of-a-kind rover once every four years. Because the missions are so infrequent, it's absolutely essential they work perfectly. So they need to be extensively tested and ruggedly designed. This leads to very conservative mission planning, with only a few different tools, and operating in the "safe" (boring) parts of the planet. JPL has gotten extremely good at these missions, but they're basically squeezing water from a stone.

Setting up human infrastructure on Mars is challenging, but once you can do that you've already overcome a lot of the limits on scientific missions. You can start spamming cheap drones and fixing/upgrading stuff that breaks rather than waiting 8+ years to get it into the next mission cycle. You can also design things as simple hand tools rather than attaching a customized robotic deployment to everything. That drives down costs, so you can try things that are riskier and yield greater advances.

Literally not an issue and never has been, rotating stations have been an idea for longer than liquid fuel rockets have been a thing.

Centrifugal force seems like a somewhat trivial solution in space or in orbit.

Obviously we just need to send them up with 1/3 of the usual fluid.
