'To Infinity And Beyond,' Or 'Pigs In Space?'

Space exploration has always captured our imaginations, united us around awe-inspiring achievement, and provided a sense of infinite possibility. But in the new era of the billionaire space race, is that sense of wonder still present? Are we poised to all reap the benefits of cheaper, privatized space flight? Or are we seeing the birth of a new playground, only for the ultra wealthy? We discuss and take listener calls with Marcia Bartusiak, Professor of the Practice Emeritus at MIT and author of several books on astrophysics and astronomy, and Kelly Beatty, Senior Editor of Cambridge-based SKY & TELESCOPE.
