Six men in a "Basement" in Russia for 520 days straight are testing out a long (!!) flight to Mars.
".... The voyagers were sealed off from terrestrial life, each one allotted a private bunk room just 32 feet square and access to a common living room, a small gym, a greenhouse, and two minuscule lavatories. The crew’s food storage room is almost as big as their living quarters, and when they entered isolation on June 3, 2010, it contained every single calorie they would consume as they soared through “space,” then spent nine days on “Mars” (in this case a small pit of red sand) before returning and exiting a year and a half later."
Food required for a crew of 6: 29,200 pounds.
But what did they eat??????
