Neil deGrasse Tyson, America’s most prominent spokesman for science and Director of New York City’s Hayden Planetarium, talks about the benefits of a cosmic perspective, the case for manned space flight and much more in this first part of our wide-ranging conversation. We also discussed Tyson's book, "Astrophysics for People in a Hurry."

Richard and Jim met Tyson at his offices at The American Museum of Natural History. While insisting he is not an advocate for manned space flight, Tyson says "history tells us" space exploration "is one of the most potent forces to operate on the scientific ambitions of a citizenry." At the height of the Apollo program in the 1960's, "you didn't need special programs to get people interested in science," Tyson explains. "There were weekly headlines about our journeys into space and you knew you needed the best of the best to breech the frontier of space."
