In almost any discussion of space exploration and observation, one question always arises. Why should we spend the money, when there are problems here on Earth? This week, we’re going to tackle this question, with a panel of people who know just how important the science of space actually is. Penny4NASA‘s John Zeller and Noisy Astronomer Nicole Gugliucci return to the show, along with Scientific American Associate Editor John Matson, and Cynthia Phillips, Senior Research Scientist at the SETI Institute. They’ll discuss the technological, social and economic benefits of exploring space, and what it really means to all of us.
