Astronauts have a down-to-Earth problem that could be even worse on a long trip to Mars: They can't get enough sleep. And over time, the lack of slumber can turn intrepid space travelers into drowsy couch potatoes, a new study shows. In a novel experiment, six volunteers were confined in a cramped mock spaceship in Moscow to simulate a 17-month voyage. It made most of the would-be spacemen act like birds and bears heading into winter, gearing for hibernation. (AP Photo/IMBP, Oleg Voloshin, Pool, File)
