WASHINGTON:
Astronauts chosen for a manned mission to Mars could be in serious
trouble if their sleep patterns are disrupted on the lengthy journey, a
520 day simulation has found.
"The success of human
interplanetary spaceflight, which is anticipated to be in this century,
will depend on the ability of astronauts to remain confined and isolated
from Earth much longer than previous missions or simulations," said
David Dinges of the University of Pennsylvania, who co-authored the
sleep study.
"This is the first investigation to pinpoint the crucial role that sleep-wake cycles will play in extended space missions."
