The impact of long-term spaceflight on cerebrospinal fluid and perivascular spaces in astronauts and cosmonauts

I’ve been saying this here for a while now, and it’s rarely well received, but no less true for that: The big rockets are the easy part, figuring out how to live there, make it to a place like Mars, be independent of Earth? That’s such a hard part we’re barely even aware of the degree of complexity, and this is the tip of an iceberg that’s been slowly emerging for years.


Dumb person here. Would artificial rotational gravity help?


I hope to be proven wrong but I don’t believe there’s much hope for baseline humans to truly thrive beyond Earth’s gravity well without some form of faster than light travel. On the other hand, barring extinction, our Posthuman descendants will inevitably spread through the galaxy in a riot of diversity of form we can barely imagine now. If our technology continues to advance at the current pace many of us alive today might live to see this happen; but by then we too would be unrecognizable to the beings we are today.


So this is why aliens are portrayed with big beads and big eyes. 😉


After the first initial crewed flights to Mars they’ll need to develop a centrifugal force gravity system for future spacecraft. I saw a video of one with a man running aground inside of it. Does anyone know more about that. Anyway, something like that could resolve the micro- gravity medical issues.
