Mars Crew Guinea Pigs Suffered Insomnia, Lethargy


Recommended Posts



Most of the crewmembers participating in a 520-day isolation study to simulate a Mars mission suffered from insomnia and other sleep disorders, a condition that left them impaired during their waking hours as well.


The finding indicates that future long-duration space travelers will need specialized lighting to replicate Earth's day-night cycles as well as other countermeasures to maintain healthy circadian rhythms, say researchers who conducted one of more than 90 investigations in the joint Russian-European Mars500 project.


I did originally read the headline as "Mars Crew Guinea Pig" and was a little confused. :unsure: I wondered why a guinea pig would suffer insomnia and lethargy! :facepalm:
