English: Surveyor I landed on the Moon at a vertical velocity of approximately 10 feet per second, rebounded about 2 1/2 inches, then came to rest. Its footpads, in the process, slightly disturbed the surface, as shown in (this picture).
"This photograph was taken on June 13, 1966, at 19:45:35 GMT," wrote HOWARD H. HAGLUND, Surveyor Project Manager, Jet Propulsion Laboratory. "The Sun at the time was 10° above the western horizon. The view is of the outboard edge of footpad 2 of Surveyor 1, and of the lunar surface material beyond it.
"The arc of lighter-colored material nearest the footpad is part of the ridge pushed up by the pad. It shows lumps, or 'clods,' up to an inch in diameter, produced by the pad pressure during landing. These are apparently made up of fine particles (less than one-fiftieth inch in diameter).
"The photograph is scientifically interesting in that it shows that the lunar surface material is cohesive. Its mechanical properties are roughly similar to those of damp garden soil."
