Dwarf Planet Ceres Thrills as a Dying Visitor Closes In

Ceres is the queen of the asteroid belt. Her first Earthly visitor is nearing its last days in spectacular style. Dawn Mission Director and Chief Engineer Marc Rayman returns with stunning images taken from just 35 kilometers or 22 miles above the dwarf planet, and a preview of the spacecraft’s last days. Planetary Society Chief Scientist Bruce Betts has a summer guide to the night sky, looks back in space exploration history and delivers another Random Space Fact. He and Mat Kaplan also have a new space trivia question for listeners.
