We engaged the Russian Federation after the collapse of the Soviet Union, not to do them a favor, but to do us a favor.

We Americans have always viewed the space program, certainly over the last 30 years, as the sort of cooperative effort that certainly helps our country but benefits all mankind.

I think in an ideal world we'd want cooperation with China because I think three major powers: Russia, China, the United States, and others working in conjunction if in fact we all have the same goals could certainly get some of these…

I think we have to be cautious that not every other nation has the same view.

I think when Americans see what's happening in Ukraine, we're uncomfortable about the fact that we're paying the Russians, what is it, $70 million to go to the International Space Station.

To be clear, as we talk about this long-term goal of landing on Mars in 2030, I think what you're describing is that all the things that we are doing now in the interim all build upon each other.

we have to be careful and realistic that we not somehow ascribe our motivations and our way of thinking to that of another nation that perhaps has different aims and goals for their space program.

It is important that the subcommittee examine NASA's plans for human exploration, including collaboration with international partners and commercial space opportunities.

If I were in charge, I would be organizing sanctions to hit exactly at the heart of the regime itself.

I think if you go back to 1960 when President Kennedy made that promise that we would land a man on the Moon and return him safely to Earth by the end of the decade.

I think this is really about enhancing our national security and we want to make sure that we don't jeopardize our national security.

I'm just always concerned that somehow we ascribe to other countries the same motivations as we have for the space program and sometimes that those things don't add up.
