Marc Rayman's monthly check-in with the Dawn mission describes the achievements of the spacecraft in its Low-Altitude Mapping Orbit (including near-global high-resolution imaging!) and explains what's next.

Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system!
