Hi
What happen if they run out of food during the 3 years mission?
Will they turn into cannibalism? (airplane crash in Chile, 1972)
What happen to ISS food stock? Is there any "invisible" space gremlin? :-)

From BBC:
Space crew 'using up food supply'
Floating in zero gravity can be a hungry business. It seems someone on the International Space Station has been super-sizing their meals: food is running so low that evacuation has been considered.
The cargo spacecraft Progress is due to take up supplies before Christmas, but astronauts might need to evacuate if its launch is delayed. Progress is due to take off from Baikonur space centre in Kazakhstan at 2119 GMT on 23 December. It will deliver food, fuel, water and packages for the American astronaut and the Russian cosmonaut who make up the space station crew.
"If for some reason the cargo spacecraft does not bring the food containers to the station by the beginning of January, the crew members may have to be urgently evacuated from there," a spokesperson for the Institute of Medical and Biological Studies told the Interfax news agency.
"Even today the crew is short of certain foodstuffs, but the situation is not critical."
Our correspondent says that, for now, the crew are being told to watch what they eat to conserve supplies. Long-duration missions in space like the ISS demand a constant supply of consumable materials from Earth. The Progress supply ship was devised as a solution to this problem.
