October 2007 marks an important anniversary. On October 4, 1957, the Soviet Union launched Sputnik, the first artificial satellite. They also launched the global competition for the military domination of space. We’ll look back this hour with Matthew Brzezinski, author of the new book “Red Moon Rising: Sputnik and the Hidden Rivalries that Ignited the Space Age” (Times Books, 2007). Brzezinski will speak to the World Affairs Council of Dallas Fort Worth this evening.
