Since day of launch, September, 27th, 2007. until today, “Dawn” traveled more than 6 billion kilometers (4 billion miles) and it is only mission that orbited two targets in the Solar system, but also the only mission that orbited dwarf planet, Ceres, March, 6th, 2015. This spacecraft is driven on ion propulsion which allowed it to take measurements from different altitudes and positions and collect more than 88,000 photos and many various measurements of asteroid Vesta and dwarf planet Ceres.
