Guest on "Your Call", Wednesday August 15th

I'll be joining the crew at "Your Call", a live public-affairs call-in show on KALW 91.7fm public radio in San Francisco on Wednesday August 15, 10-11am PST to talk about NASA's agenda for space exploration. A great opportunity to answer questions about what we know about outer space, how we choose what to explore, and how space exploration is done. Tune in or check out the archived recording at
