A six-member crew was sealed in a tiny replica of a space ship for a simulated journey to Mars today at Moscow's Institute for Medical and Biological Problems. Man, 520 days away from the Internet sounds great right now.

The crew of the Mars500 experiment—comprised of three Russians, two Europeans and a Chinese guy—will be subjected to the same challenges as a potential future mission to Mars, including a 20-minute communications delay, limited supplies, missing the new season of Mad Men and being cooped up with five other dudes in a space that is about the size of three Manhattan studio apartments. Let's hope this mission goes smoother than the 1999 mission, when a guy tried to kiss his female crewmate and the whole thing had to be called off. Even in (simulated) space, men are pigs.
