As we enter a new era in space travel, a study looking at how the human brain reacts to traveling outside Earth's gravity suggests frequent flyers should wait three years after longer missions to allow the physiological changes in their brains to reset.
It seems as though current attempts to mitigate the drawbacks of microgravity are not fully adequate. Likely deep space missions will have to use something like nuclear engines that can maintain 'thrust gravity' over long periods
It should be noted we don't currently fully understand what this could mean:
"We don't yet know for sure what the long-term consequences of this is on the health and behavioral health of space travelers," she said, "so allowing the brain time to recover seems like a good idea."
I wonder if this will have implications for minimum/maximum lengths of missions to places like Mars, or if the atmospheres and environments of other planets will have their own consequences dissimilar to this.
