The life of explorer and teacher Dr. Bruce Murray was celebrated last November 10th at Caltech.  This week we present a few excerpts from the tributes paid to the former JPL Director and co-founder of the Planetary Society.  Emily Lakdawalla points us to spectacular images and video from the launch of the Chang’e 3 lunar lander by China, and Bruce Betts speaks of the anticlimactic exit of Comet ISON.  Bruce and Mat Kaplan also entertain proposals for putting DAD in space in this week’s space trivia contest.
