Synopsis
The moon is a world of mountains, craters, valleys, peaks and huge waterless seas. Of special interest are the cracklike features known as rills, which are unlike anything we find on earth. Patrick Moore talks about them to Dr Lionel Wilson of the University of Lancaster, who has been making a careful study of these remarkable lunar features.
