Dawn is beginning its departure from Vesta, spiraling upward from its low-altitude mapping orbit to a higher one from which it will map north polar terrain not visible during the earlier mapping orbit.
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.

On April 18, Dawn will attain its greatest separation yet from Earth, nearly 520 million kilometers (323 million miles) or more than 3.47 astronomical units (AU). Well beyond Mars, fewer than a dozen spacecraft have ever operated so far from Earth. At this extraordinary range, Dawn will be nearly 1,400 times farther than the average distance to the Moon (and 1,300 times farther than the greatest distance attained by Apollo astronauts 42 years ago). The deep-space ship will be well over one million times farther from Earth than the International Space Station and Tiangong-1.

The Dawn mission's Project System Engineer Marc Rayman reports that Dawn concluded 2011 more than 40 thousand times nearer to Vesta than it began the year. It is now at its lowest altitude of the mission, conducting a detailed exploration of the protoplanet and continuing to make new discoveries.

In this update on the Dawn mission, project system engineer Marc Rayman reports that the probe is headed for its low altitude mapping orbit (LAMO), where it will focus on making a census of the atomic constituents and on mapping the gravity field in order to determine Vesta's interior structure.

Dawn has completed another wonderfully successful phase of its exploration of Vesta, studying it in unprecedented detail during the past month.
