Seven hours before the launch, the astronauts will undergo medical tests, mainly on blood pressure and pulse. Then they'll put on their space suits. When they're finished getting dressed, the spacemen will have one more medical test to check their physical condition inside the suits. The whole process takes about 2 hours.

Their next step will be sitting in their launch seat, just like this.

Space suit designer Xi Libin said, "They will stay inside the chairs in this way during the launch. It will protect them from the impact of weightlessness or high g-force situations."

On Thursday, a ceremony will be held right before the astronauts' departure. There they will receive one last important thing before journeying into space, the best wishes of the entire nation.
