Dawn usually interrupts ion thrusting once a week for about eight hours to point its main antenna to Earth. On November 30, however, instead of resuming thrusting, it dutifully followed different instructions that were stored onboard.

Dawn entered the main asteroid belt on November 13. As it ventures ever deeper into this vast collection of material between Mars and Jupiter, it may be tempting to think of the spacecraft constantly dodging asteroids.

Dawn has devoted another month to thrusting with its ion propulsion system, ever with its sights set on its rendezvous with Vesta in July 2011.

Dawn is celebrating the second anniversary of leaving its home planet by engaging in the same function it has performed most of its time in space: with the utmost patience, it is using its ion propulsion system to gradually modify its orbit around the Sun.

Dawn continues on course for its pas de deux with Mars on February 17. The planet's gravity will gracefully assist the spacecraft on its way to rendezvous with its intended celestial partners Vesta and Ceres in the more distant asteroid belt.

The Dawn spacecraft is healthy and on course for its flyby of Mars early next year. The planet's gravity will help boost the probe on its way to rendezvous with Vesta.

On the first anniversary of its departure from Earth, Dawn continues with what it has been doing for most of its time in space. With the greatest patience, it is gently reshaping its orbit around the Sun with its ion propulsion system.

The Dawn spacecraft continues to make good progress on its adventure to unlock scientific secrets hidden deep in the main asteroid belt, between Mars and Jupiter.
