Protesting the IAU Planet Definition and a SMART-1 Lunar Impact Recap

We have a busy show -- Mark Sykes, Director of the Planetary Science Institute, talks about his petition to the International Astronomical Union protesting its planet definition. And we look back a week to the lunar impact of Europe's SMART-1 orbiter in a teleconference with Detlef Koschny at the European Space Operations Center. Emily Lakdawalla's Q&A looks at New Horizons after Pluto, and a special What's Up! trivia contest finds the laughs in Pluto's demotion.

Guests

• Detlef Koschny, European Space Operations Centre
