The wide-angle picture (left), obtained by the spacecraft’s MapCam digital camera, reveals a 590-foot (180-meter) extensive space with many rocks, together with some giant boulders, and a “pond” of regolith that’s principally devoid of huge rocks.
The 2 nearer pictures, obtained by the high-resolution PolyCam digital camera, present particulars of areas within the MapCam picture, particularly a 50-foot (15 meter) boulder (prime) and the regolith pond (backside). The PolyCam frames are 101 toes (31 meters) throughout and the boulder depicted is roughly the identical dimension as a humpback whale.
The photographs have been taken on February 25 whereas the spacecraft was in orbit round Bennu, roughly 1.1 miles (1.eight km) from the asteroid’s floor.
The remark plan for today offered for one MapCam and two PolyCam pictures each 10 minutes, permitting for this mixture of context and element of Bennu’s floor.
