Everyone that I've talked to who's been to space has thoroughly enjoyed the experience, and what you often hear them say is: It was great, but we just had to come home.

Science, for hundreds of years, has spanned the differences between cultures and between countries.

The microgravity or the very, very low amount of gravity that we have up in space forces some changes in different processes. It forces changes in us as human beings.

Life continues in lots of places, and life is a magical thing.

Gravity pulls our bodily fluids down, like water in a glass goes to the bottom part of a glass. In space, the water doesn't stay in the bottom of the glass. It distributes itself evenly over time throughout the entire volume of the glass.

There are some very significant changes in the way the fluids are distributed in our body, the way our heart functions initially, and as well as our bone and muscle.

I feel blessed to be here representing our country and carrying out th research of scientists around the world... I hope you could feel the positive energy that beamed to the whole planet as we glided over.
