From Ground Zero in New York to ground zero in Kabul, to police stations, subway platforms, and darkened theaters, NPR's Peabody-Award-winning correspondent Scott Simon brings a well-traveled perspective to his role as host of Weekend Edition Saturday.

Alan Cheuse has been reviewing books on All Things Considered since the 1980s. His challenge is to make each two-minute review as fresh and interesting as possible while focusing on the essence of the book itself.

Mike Pesca first reached the airwaves as a 10-year-old caller to a New York Jets-themed radio show and has since been able to parlay his interests in sports coverage as a National Desk correspondent  for NPR based in New York City.

Pesca enjoys training his microphone on anything that occurs at a track, arena, stadium, park, fronton, velodrome or air strip (i.e. the plane drag during the World's Strongest Man competition). He has reported from Los Angeles, Cleveland and Gary. He has also interviewed former Los Angeles Ram Cleveland Gary. Pesca is a panelist on the weekly Slate podcast “Hang up and Listen”.

Robert Smith is a correspondent for NPR's Planet Money where he reports on how the global economy is affecting our lives.

If that sounds a little dry, then you've never heard Planet Money. The team specializes in making economic reporting funny, engaging and understandable. Planet Money has been known to set economic indicators to music, use superheroes to explain central banks, and even buy a toxic asset just to figure it out.

Smith admits that he has no special background in finance or math, just a curiosity about how money works. That kind of curiosity has driven Smith for his 20 years in radio.

Elizabeth Shogren is an NPR News Science Desk correspondent focused on covering environment and energy issues and news.

Since she came to NPR in 2005, Shogren's reporting has covered everything from the damage caused by the BP oil spill on the ecology of the Gulf Coast, to the persistence of industrial toxic air pollution as seen by the legacy of Tonawanda Coke near Buffalo, to the impact of climate change on American icons like grizzly bears.
