Flying High on SOFIA
Planetary Radio returns to SOFIA, the Stratospheric Observatory for Infrared Astronomy, but this time we fly in the giant 747 turned telescope platform. It was a night to remember. Emily Lakdawalla has the lowdown on New Horizons’ tiny 2019 target far beyond Pluto. Bill Nye looks back at five years as leader of the Planetary Society. Bruce Betts joins Mat Kaplan at more than 40,000 feet for a very high edition of What’s Up.
