Dawn baseline interplanetary trajectory for primary mission.
The thin solid lines represent the orbits of Earth, Mars, Vesta, and Ceres. The duration of the coast periods during interplanetary cruise are exaggerated in this depiction. In addition, thrusting at Vesta and Ceres is not shown. The dates on the time plot reflect the Pacific time zone. Dawn will remain in orbit around Ceres at the end of its primary mission.
