These images from NASA's Dawn spacecraft are located in asteroid Vesta's Numisia quadrangle, in Vesta's northern hemisphere. The bottom part of the rim of Fabia crater is much fresher than the top part of the rim.

HAMO and LAMO Images of Fabia Crater

These Dawn framing camera (FC) images of Vesta show Fabia 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. Fabia is the large crater that dominates 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 bottom part of the rim of Fabia crater is much fresher than the top part of the rim. The slumped material that makes the top part of Fabia's rim look much more degraded is shown in more detail in the LAMO image: small boulders and the mottled appearance of the slumped material can be clearly seen. Layering in the bright material just below Fabia's rim can also be seen in the LAMO image.

These images are located in Vesta's Numisia quadrangle, in Vesta's northern hemisphere. NASA's Dawn spacecraft obtained the left image with its framing camera on Oct. 19, 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 Jan. 24, 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 20 meters (66 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.
