English: (This) mosaic of TV pictures ... forms a broad vista of the rim of a low crater several hundred yards distant from the landing site of Surveyor 1.

ZDENEK KOPAL, of the University of Manchester, in England, made the following points about it: "What makes this photograph unique is the vantage point from which it was taken. The crater, one of hundreds of thousands of this type on the Moon, is much akin to the well-known Meteor Crater in Arizona; namely, caused by the impact of an outside mass.

"However, from the shape of the ramparts (and boulders dispersed around them), we may conjecture that the crater itself is likely to be of secondary, rather than primary, origin. Also, whereas the Meteor Crater is probably not more than 100 000 years old, this lunar one may well be 10 times older. So slow are the grinding processes of cosmic obliteration on the Moon!"
