This is a hopeful signal that the trend of downturns will reverse. International students play such a large part of graduate education in the U.S.

The U.S. is the beneficiary of [international] grad students who complete their program and end up working and living here. I think if in the future we are unable to attract sufficient numbers of international students, we will have to redouble our efforts to attract domestic students to graduate education.

We're entering an enhanced competition for global talent. We have to make sure that the environment for attracting international students is the best it can be. There are still challenges ahead.

NASA has and will always continue to involve colleges and university students. As the agency moves forward to implement the vision for space exploration, those students will play a vital role in its success.

You never control your classroom. Your students do. They always have; they always will. You cannot be coercive enough for them.

I was glad I got to play one year with them. Hopefully, I will get to play against them in the future.
