Astronomer Jim Bell writes about NASA's longest running program, Voyager

  In 1977, NASA launched two space probes, Voyager 1 and 2. Voyager 1 became the first spacecraft to exit the solar system in 2013, and Voyager 2 should follow this year. It is the only spacecraft to have visited all four giant outer planets in the solar system, and is NASA's longest-running mission. In his latest book, ?The Interstellar Age: Inside the Forty-Year Voyager Mission?, Jim Bell explores the Voyager mission, the team that started it and monitors both probes, and details the engineering and science behind them. Jim Bell is a professor in the School of Earth and Space Exploration at Arizona State University, an adjunct professor in the Department of Astronomy at Cornell University, and the president of the Planetary Society. He joins us to discuss the importance of the Voyager mission, 40 years ago, and today.
