Space Audity

We've all heard the iconic recordings from the Apollo missions. But how exactly does NASA manage to run live audio between Earth and the moon? And how might we chat with astronauts on Mars and beyond? Featuring Astronaut Peggy Whitson, NASA Audio Engineer Alexandria Perryman, and Astrophysicist Paul Sutter. Twenty Thousand Hertz is produced out of the studios of Defacto Sound and hosted by Dallas Taylor.  Follow the show on Twitter, Facebook, & Reddit.
