“We were a competitor in perhaps the greatest peacetime competition of all time: the space race—USA versus USSR. Like a war, it was expensive. Like a war, each side wanted intelligence on what the other side was doing. And I’ll not assert that the space race was a diversion which prevented a war. Nevertheless, it was a diversion. It was intense. It did allow both sides to take the high road with the objectives of science and learning and exploration.”
