There's a lot of different things that we do during life that could personally harm us and I choose not to stop doing those things.

Things are going very smoothly. As expected, there are some minor glitches, and the eight minutes that it took us to get to orbit, we trained months and months for, and didn't have to use any of that preparation, other than being aware and ready.

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.

We've had such thorough training, we've had an excellent team on the ground. With the minor glitches that have occurred, we've been able to take care of them. And the teams on the ground are getting tons of incredible data.

Whenever I do get to look out, it is glorious. Even the stars have a special brightness.

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

As a physician, I understand how important it is to collect data on people so we can understand what's happening with them. I will be in the position to help enable that knowledge.
