>>This animation, made from images taken by the advanced Moon Imaging
>>Experiment (AMIE) on board ESA's SMART-1 spacecraft, shows Kepler crater
>>on the Moon.
>> AMIE obtained this sequence on 13 January 2006 from a distance ranging
>>between 1613 and 1702 kilometres from the surface, with a ground
>>resolution between 146 and 154 metres per pixel.
>>
>>The imaged area is centred at a latitude of 37.8? South and longitude
>>9.0? East. Kepler is a small young crater situated between Oceanus
>>Procellarum and Mare Insularum. It has a diameter of 32 km and it is 2.6
>>kilometres deep.
>>
>>Kepler displays a ray system that overlaps with rays from other craters
>>and which extends over 300 kilometres. The outer wall shows a slightly
>>polygonal shape. The interior walls of the crater are slumped and
>>slightly terraced, and descend to an uneven floor and a minor central
>>rise.

>>This particular sequence of images demonstrates the so called 'tracking
>>mode' of the SMART-1 spacecraft, used to track a fixed target when
>>flying over it. While flying over Kepler, the clear filter of the camera
>>was always pointed to the same position.
>>
>>To stay within the thermal constraints, the spacecraft had to change its
>>roll during the images acquisition, thus the image is slightly rotated
>>when passing from one frame to the next.
>> Thanks to the tracking mode it is possible to obtain information about
>>the size and roughness properties of the soil. It also allows multiple
>>stereo views of the target's topography.
>>
>>Kepler crater is named after Johannes Kepler (1571-1630), German
>>astronomer known for his three laws of planetary motion.
