LIFE is the Planetary Society's Living Interplanetary Flight Experiment. Our own Bruce Betts is the Experiment Manager. He tells us about this attempt to send living organisms to Mars' moon Phobos and return them to Earth. Bill Nye is worried about a lack of plutonium to power deep space missions. Emily Lakdawalla's Q&A explains why New Horizons won't be going into orbit at Pluto. Bruce Betts returns for his usual night sky update and share a new space trivia contest with Mat and listeners.


No trivia contest spoilers please!
