The Dawn mission was launched on 27 September 2007. The objective of the mission is the most thorough investigation of the asteroids Vesta and the dwarf planet Ceres. With Dawn, researchers expect to find out what happened during the first few millions of years after the planets were formed.
Varied impact craters, valleys, canyons and mountains among the highest in the Solar System are revealed on the first images of the asteroid Vesta.
The dwarf planet Ceres would be quite an uncomfortable place if one were to actually stand on its surface – with a rather 'chilly' temperature of minus 60 degrees Celsius by day, which gets colder during the night. Hard, frozen ground and craters spanning kilometres – in all shapes and sizes.
Currently just 385 kilometres away from the surface, the Dawn spacecraft is orbiting Ceres and acquiring images that show the dwarf planet at an unprecedented resolution of just 35 metres per pixel. These images allow scientists to look at a surface strewn with craters, fractures, domes and bright areas.
The dwarf planet Ceres measured a mere nine pixels across on an image acquired by NASA's Dawn orbiter on 1 December 2014. Since then, the planetary researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have received thousands of images showing the dwarf planet and its unusually varied surface.
