Mark your calendars, please: TED Radio Hour returns to the NPR airwaves on Friday, March 1. After a popular first season — named the Best New Audio Podcast of 2012 by iTunes — NPR and TED have expanded the series into a weekly program. And for its second season, TED Radio Hour also has a new host — Guy Raz, who you probably know as the host of Weekend All Things Considered and the creator of Three-Minute Fiction.

Each episode of TED Radio Hour will turn an extraordinary idea inside out, using incredible speakers from the TED stage as a jumping off point. With music and lush soundscapes, each episode takes you on a journey that may well flip your perspective. (Listen to the preview below.) The first two episodes of the 30-part season will be “The Unquiet Mind,” premiering on NPR on March 1, and “Peering Into Space,” debuting on March 8. Podcasts of the show will also be available through iTunes.

Stay tuned to the TED Blog next week for an interview with Guy Raz, where we’ll share which episodes he’s most excited for this season … and his secret skill.
