"Outer space is free. It is unscarred by conflict. No nation holds a concession there. It must remain this way."

"I believe that government must guard freedom of inquiry--and extend it."

"The voyage of our scientists should be to make new discoveries--not just to confirm old dogmas."

"We have made clear that if the other side desires to discuss peace at any time, we will be very happy to have appropriate arrangements made to see that that is carried out."
