The weekly half-hour Planetary Radio is Public Radio's only program looking at humankind's quest for knowledge about our solar system and beyond.

Stations! New episodes will be available one day later in the week beginning the week of February 13, 2017. So new episodes will be available here late Tuesday evening/early Wednesday morning rather than late Monday evening/early Tuesday morning. Contact Mat Kaplan if you have questions or concerns.

Beginning with our December 7, 2015 episode, files are 192 kilobits per second stereo MP3s. Episodes prior to that date are 128 kbps stereo MP3s. Planetary Radio is also available as a mono MP2 from the Public Radio Satellite Service (PRSS) and the Public Radio Exchange (PRX). Pacifica's AudioPort makes episodes available as 192 kbps stereo MP3s. Information about the guests and topic of each week's show can be found on the Planetary Radio home page.
