English Abstract

There is no specific way to calculate the number of meteorites that bombard the Earth because of most of these meteorites burn up in the atmosphere, the moon is the earth’s nearest neighbor, so it is possible to think that meteorites bombard it as well.

However, the moon has no atmosphere so an approaching meteorites could hit it and form a crater, this makes the Lunar surface perfect location to calculate the number of meteorites that bomber the Lunar surface and study the change on its surface due to meteorites impact by comparing images that taken by a satellite for a specific area and in different time.

The most important missions that sent back photographic imagery of the lunar surface were the Lunar Orbiter program 1966-1968, and the Clementine mission1993-1999, from these two missions, images will be compared in order to discover if lunar surface has any change during the past thirty years that separate the two missions.

After brief search for the images, the experimental work focuses on a specific region at the crater “Plato”, a large part of the work will be in preparing the images for the comparison.

The images will be spatially manipulated, to achieve the appropriate perspective, direction, scale, and distance, to produce pairs of images that "match" each other, and then they can be digitally compared.

Comparison techniques include using images enhancement and change detection techniques.

Where applying images enhancement helps to show the small detail, and applying change detection helps to see if any new surface features have developed, particularly a crater that can be caused by a meteorite collision.

If the lunar surface is examined using this comparison techniques, a large database of information could be created that would allow researches to document any changes to the lunar surface The experimental works show good results, these results contain many changes that happened on the lunar surface due to impact cratering and other reasons.
