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.

Quote"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).https://www.space.com/artemis-1-virtual-reality-watch-live
