Astronauts are very professional and when they're preparing for launch, they prepare for it as the most serious endeavor of our lives.

Being an astronaut is a wonderful career. I feel very privileged. But what I really hope for young people is that they find a career they're passionate about, something that's challenging and worthwhile.

I think of it as a good opportunity to let, in particular, school kids know that this job and other interesting jobs in science and engineering are open to anyone who works hard in school and gets a good education and studies math and science. And that it's not just for a select group of people.

The ISS operates as the 'anchor customer' in low earth orbit to support new commercial space services, including delivery of cargo and, before long, crew transportation services.

I've been teaching myself the fundamentals and being around some good players, but also been learning to play team games, playing 3-on-3s, playing 1-on-1s, playing 5-on-5s, playing 21. There are guys bigger than me on the court, but I've had numerous comparisons to Ty Lawson.

Education is a way of empowering people; it opens up so many doors and is fundamental to everybody. And teachers are not often appreciated in the way that they should be.

We think we can contribute something toward the improvement of public education in our country.

We really shouldn't be running education like a supermarket where you compare prices.
