Amy Mainzer: Asteroid Hunter

After taking over 10 million images of more than 30,000 solar system objects, the NEOWISE mission is finally in its last months.  Principal Investigator Amy Mainzer returns with an update on this phenomenal success and a look ahead toward a much more powerful asteroid and comet hunter called NEOCam.  It’s not just about defending our planet.  We are learning the origin story of Earth and other worlds.  Bruce Betts also shares a story or two, along with a new space trivia contest, in this week’s What’s Up segment.  Learn more about this week’s topic and see images here: http://www.planetary.org/multimedia/planetary-radio/show/2018/0509-amy-mainzer-neowise.html
