week #3 reading journal - Mock Mrs mission

 To simulate a mission to Mars, 6 men lived in cramped, window-less compartments for more than 17 months. This experiment was the longest mock space mission ever. They were measuring human responses to the confinement, stress, and fatigue of a round trip to Mars, of cause in weightlessness. The facility was institute for Medical and Biological Problems, Russia’s premier space medicine center, included living compartments the size of a bus, connected with several other similarly sized compartments for experiments and exercise. A real flight to Mars is a distant prospect due to challenges such as creating a compact and relatively lightweight spacecraft that would shield the crew from deadly cosmic radiation.
