Dawn obtains first low-altitude images of Vesta
The primary science objectives in this orbit are to learn about Vestaò??s surface composition and to probe the interior structure of the asteroid by measuring its gravity.
NASAò??s Dawn spacecraft has sent back the first images of the giant asteroid Vesta from its low-altitude mapping orbit. The images, obtained by the framing camera, show the stippled and lumpy surface in detail never seen before, piquing the curiosity of scientists who are studying Vesta for clues about the solar systemò??s early history.
At this resolution, the surface shows abundant small craters and textures such as small grooves and lineaments reminiscent of the structures seen in low-resolution data from the higher-altitude orbits. Also, this fine scale highlights small outcrops of bright and dark material.

Dawn returned the images to Earth December 13. Mission scientists plan to acquire data in the low-altitude mapping orbit for at least 10 weeks. The primary science objectives in this orbit are to learn about Vestaò??s surface composition with the gamma-ray and neutron detector and to probe the interior structure of the asteroid by measuring its gravity.
