Small bodies will hit the big time next year; a sample return from asteroid Bennu and the launch of both the DART and Lucy missions could unravel puzzles about the formation of the solar system, as well teach us how to deflect any asteroids headed our way. Meanwhile, the Juno mission to Jupiter has shown us its hard-to-study poles, where swirling gas and magnetic fields rule. On Earth, warmer temperatures threaten peat bog biodiversity and the structure of the Arctic. And massive wildfires have sent soot circling the globe. They’re all highlights from the fall meeting of the American Geophysical Union.Guests: Steve Levin – Project Scientist for NASA’s Juno mission Christopher Fernandez – Research associate, Department of Forestry, Michigan State University Mike Fromm – Meteorologist, U.S. Naval Research Laboratory Nancy Chabot – Nancy Chabot is a planetary scientist at the Johns Hopkins Applied Physics Laboratory and DART mission coordination lead Tom Statler – Program scientist on the Lucy mission in the planetary science division and planetary defense coordination office at NASA headquarters in Washington, D.C.   Learn more about your ad choices.
