These Dawn images show a region around Vesta's equatorial troughs with two different resolutions. The image on the left has a lower resolution of 260 meters per pixel and the image on the right has a higher resolution of 66 meters per pixel. Many areas of dark material are visible in the lower-resolution image, including the dark hill (in box). The higher-resolution image displays more detail of this hill, such as its irregular contact with the rest of Vesta's surface. Many more details are also visible in the right hand image when compared to the left hand image, such as small linear grooves running roughly parallel to the troughs and slumping/landslide features in the crater in the bottom right corner. The wider-view image was obtained by Dawn during Survey Orbit, on August 20, 2011, and the narrower-view image was taken near the High-Altitude Mapping Orbit, on September 20. These images were taken through the camera's clear filter. The distance to the surface of Vesta was 2740 and 673 kilometers. Other spacecraft get wide- and narrow-angle views by carrying two cameras with different optics; Dawn accomplishes the same thing with a single camera by adjusting the height of its orbit.
