(Phys.org)—NASA's Dawn mission is releasing two parting views of the giant asteroid Vesta, using images that were among the last taken by the spacecraft as it departed its companion for the last year.
The first set of images is a color-coded relief map of Vesta's northern hemisphere, from the pole to the equator. It incorporates images taken just as Dawn began to creep over the high northern latitudes, which were dark when Dawn arrived in July 2011. The other image is a black-and-white mosaic that shows a full view of the giant asteroid, created by synthesizing some of Dawn's best images.
"Dawn has peeled back the veil on some of the mysteries surrounding Vesta, but we're still working hard on more analysis," said Christopher Russell, Dawn's principal investigator at UCLA. "So while Vesta is now out of sight, it will not be out of mind."
These will be the last daily images during the cruise to Dawn's second destination, the dwarf planet Ceres. Other images will be highlighted as findings are made. Other data will be archived at pds.nasa.gov .
Dawn left Vesta on Sept. 4, 2012 PDT (Sept. 5, 2012 EDT). The spacecraft is using its ion propulsion system to travel to Ceres. It is expected to arrive in early 2015.
