Dawn: Ten Years of Exploration
b'Dawn Mission Director and Chief Engineer Marc Rayman helps us salute the ion-engine
powered spacecraft that first orbited asteroid Vesta in the main asteroid belt and then moved
to dwarf planet Ceres, revealing two fascinating worlds. The new US National Space Council
met in Washington DC last week. Director of Space Policy Casey Dreier reviews it. Planetary
Society CEO Bill Nye reports from Australia where he addressed the International Astronautical
Congress. More space art can be yours if you win the latest What\\u2019s Up space trivia contest.
