Few years ago, when George W. Bush was the American President, one of his very ambitious plans for 2020 was to send men to the Moon and to Mars.

This time I only had read some bits of information regarding the plan without elaborating what kind of preparations the US are doing. However, Russia, though not boasting its ambition to do the same as usual, recently has proudly announcing its 6 men endured Mars flight simulation experiment emerged from a metal hatch after 105 days of isolation in a mock spacecraft, still smiling after testing the stresses that space travelers may face on the journey to Mars.

Though the experiment is belittled by those space explorer veterans, but many were convinced that it is one of the best preparations that Russia can do at the moment if it’s really determined to reach Mars.
