HI MOM: Time Changes

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.

Bruce Betts and Mat Kaplan are back from their flight on the SOFIA 747 with a game to give away.  “Xtronaut” lets you manage your own robotic mission across the solar system.

9/14/15 Planetary Radio: OSIRIS-REx Readies for Asteroid Bennu

CEO Randa Milliron introduces us to Interorbital Systems, which wants to put your payload in orbit for as little as $8,000. Can they do it? Emily Lakdawalla returns with a preview of 2017’s biggest solar system exploration events. Bill Nye the Science Guy congratulates and thanks outgoing NASA Chief Scientist Ellen Stofan.  We’re giving away another beautiful science/science fiction fine art print in this week’s What’s Up segment.

A Little Rocket Company Shoots for the Moon

They may disagree about nearly every other issue, but many Republican and Democratic congressional representatives find common ground where there is no ground—in space.  Adam Schiff’s California district includes the Jet Propulsion Laboratory.  He is as enthusiastic a fan of the final frontier as you are likely to find under the capitol dome in Washington D.C. Planetary Society Digital Editor Jason Davis has just returned from the famed Mirror Lab at the University of Arizona.  He witnessed the creation of a mirror that will soon become part of the Giant Magellan Telescope.  The International Astronomical Union has made it official.  Bruce Betts is all over the first, confirmed interstellar object to enter our solar system.  He tells us about it in this week’s What’s Up.
