During the divorce process, I lived alone and tended to get extremely down on myself.

Computers allow us to squeeze the most out of everything, whether it's Google looking up things, so I guess that tends to make us a little lazy about reading books and doing things the hard way to understand how those things work.

A family needs to work as a team, supporting each other's individual aims and aspirations.

Anything we can do in the near future that begins to stimulate the interest of people - seeing somebody down the street have an opportunity to go into space - buoys up the whole neighborhood.

Mars, we know, was once wet and warm. Was it home to life? And what can living and learning to work on its rust-colored surface teach us about the future of our own planet, Earth? Answering those mysteries may hold the key to our future.

I know: If you're looking down at Earth, you're looking through an atmosphere that has a bit of haze in many places and not just occasional clouds.

Being first outside the spacecraft would bring much more responsibility, and I really wasn't looking for that.

Mars has a bit of air pressure; maybe we can build up that atmosphere to be a bit more accommodating to humans.

I think the climate has been changing for billions of years.

For the future, primarily, we must educate people in science, engineering, technology and math.

As someone who flew two space capsules and twice landed in the ocean, I can attest from personal experience how much logistics work is needed to get you home.
