To Phobos and Back

Highlights of a Planetary Society seminar about the little potato-shaped moon of Mars. We'll hear from Tom Duxbury, Phobos expert at JPL, from Alexander Zakharov of the Russian Space Research Institute about plans for a Phobos sample return mission, and from The Planetary Society's Bruce Betts, manager of a proposed experiment for that mission which may help determine whether life could have come to Earth from Mars. Bruce also joins us for a What's Up night sky update with a new space trivia question, while Mat announces yet another prize in the Planetary Radio fifth anniversary contest.
