Half a century has passed since Neil Armstrong and Buzz Aldrin imprinted humanity's first footsteps upon another world. Apollo 11 was the culmination of a decade's worth of fervent activity in which the United States marshaled resources and manpower at a pace not seen outside of warfare. Space historian Dr. Roger Launius joins the show to explain why Apollo happened the way it did, how a moonshot briefly became a solution to a national security problem, and why it is unlikely to happen again. Casey Dreier also provides a space policy update.  More resources about this month’s topics are at http://www.planetary.org/multimedia/planetary-radio/show/2019/space-policy-edition-39.htmlLearn more about your ad choices.
