https://www.frontiersin.org/articles/10.3389/fncir.2022.815838/full  - Brain Connectometry Changes in Space Travelers After Long-Duration Spaceflight.

Physiological changes from being in space reverse themselves once an astronaut is back on Earth, others can be offset through diet, exercise, and other actions.
But when it comes to the brain, changes may be more permanent for space travelers, as found by the new peer-reviewed study published Friday in Frontiers of Neural Circuits.

After spaceflight, Wuyts and his team identified tiny "microstructural" changes that occurred not only in the sensorimotor tracts of the brain but also in regions like the cerebellum, which plays a big role in movement and mediating social behavior.
Changes were also seen in white matter tracts connecting the corpus callosum (the communication bridge between our left and right brain hemispheres) and regions involved in language processing and executive function.
On the final MRIs taken seven months later, some microstructural changes reverted to pre-flight conditions—but not all of them. It's one of the first major pieces of evidence to demonstrate that space can permanently alter the human brain.
Wuyts' team thinks the space environment (and its microgravity conditions) causes fluid cavities in the brain to dilate, pushing adjacent neural tissue around.
Holy crap, that is amazing, and intimidating.  Space travel and colonization seems like such a natural progression for the future, but there is so much still unknown.

If you ever find yourself in need of a safe space then you're probably going to have to stop calling yourself a social justice warrior. You cannot be a warrior and a pansy at the same time   Mike Adams (RIP Mike)

That's pretty cool, a 40 sec. eclipse.  O0

We can't live under the threat of a c*nt because he's threatening nuclear Armageddon.

That's great. Now how do we get him down?  ???

Perhaps two jet-suited men could fly an injured person back down, suspended on a rope between them?  That is how swallows used to get coconuts to England, after all.   :D

Sir Slash

England has coconuts?!   :o  How'd I miss that? Next thing you'll be telling me is they have American Football.  ???

#869
Artemis I is scheduled for liftoff on August 29th at approximately 8:33am ET.  This is a test of the Space Launch System (SLS) that will send an Orion capsule with 3 test dummies into Lunar orbit and back to Earth. 



Artemis 1 will last for three weeks and will test all the rocket stages and spacecraft that would be used in later Artemis missions. After reaching orbit and performing a trans-lunar injection (burn to the Moon), the mission will deploy ten CubeSat satellites and the Orion spacecraft will enter a distant retrograde orbit for six days. The Orion spacecraft will then return and reenter the Earth's atmosphere, protected by its heat shield, and splash down in the Pacific Ocean.

USA is heading back to the Moon.  \m/

"Artemis Ascending" will use 360-degree virtual reality to let participants feel like they're standing near the Artemis 1 mission as it lifts off no earlier than Monday (Aug. 29). You'll be able to virtually witness NASA's most powerful rocket yet, the Space Launch System (SLS) megarocket, as it lifts the Orion spacecraft on a journey to the moon. Liftoff is set for 8:33 a.m. EDT (1233 GMT).
