It's a process of overcoming fear.

Why fear?

Why can we carry on a conversation now in a calm, relaxed manner? First of all, there is air pressure, which keeps us grounded. Second, there is oxygen, which is a precondition for us to talk to each other. If we were in a vacuum, we'd cease to exist.

But you have a space suit.

A space suit does not guarantee your safety 100 percent. You are always taking a risk.

How big is the risk?

Our engineers and technicians all make sure the space suit works well every single time. Every time, the suit provides you with a snug yet safe living space. But technical equipment can fail sometimes. Once there is a technical failure, the risks are increased.

If fear occurs, can it be conquered?

It has to be. If not, you're not up to the mission.
