These images from NASA's Dawn spacecraft are located in asteroid Vesta's Floronia quadrangle, in Vesta's northern hemisphere. There are fine-scale streaks of dark and bright material originating from just underneath Licinia's scalloped rim.

These Dawn framing camera (FC) images of Vesta show Licinia crater at both HAMO (high-altitude mapping orbit) and LAMO (low-altitude mapping orbit) resolutions. The left image is the HAMO image and the right image is the LAMO image. Licinia crater is the large crater that does not entirely fit into the LAMO image. The LAMO image is approximately 3 times better spatial resolution than the HAMO image. In images with higher spatial resolutions smaller objects can be better distinguished. The fine detail of the interior structure of Licinia crater is spectacularly revealed in the LAMO image. The center of Licinia crater is particularly interesting because there is a small mound of material that is surrounded by darker, smooth material. There are also many tiny craters on this smooth material. There are lobes of material slumping onto this smooth material from the sides of the crater. Further up the crater's walls, there are fine-scale streaks of dark and bright material originating from just underneath Licinia's scalloped rim.

These images are located in Vesta's Floronia quadrangle, in Vesta's northern hemisphere. NASA's Dawn spacecraft obtained the left image with its framing camera on Oct. 11, 2011. This image was taken through the camera's clear filter. The distance to the surface of Vesta is 700 kilometers (435 miles) and the image has a resolution of about 63 meters (207 feet) per pixel. This image was acquired during the HAMO (high-altitude mapping orbit) phase of the mission. NASA's Dawn spacecraft obtained the right image with its framing camera on April 1, 2012. This image was taken through the camera's clear filter. The distance to the surface of Vesta is 272 kilometers (169 miles) and the image has a resolution of about 19 meters (62 feet) per pixel. This image was acquired during the LAMO (low-altitude mapping orbit) phase of the mission.

The Dawn mission to Vesta and Ceres is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, for NASA's Science Mission Directorate, Washington D.C. UCLA is responsible for overall Dawn mission science. The Dawn framing cameras have been developed and built under the leadership of the Max Planck Institute for Solar System Research, Katlenburg-Lindau, Germany, with significant contributions by DLR German Aerospace Center, Institute of Planetary Research, Berlin, and in coordination with the Institute of Computer and Communication Network Engineering, Braunschweig. The framing camera project is funded by the Max Planck Society, DLR, and NASA/JPL.
