Surveyor 5

Surveyor 5 was the fifth lunar lander of the Surveyor program.

A total of 19,049 images were transmitted to Earth.

The mission experienced a helium leak that could have resulted in failure. An improvised landing sequence was successful and data was received for 2 weeks after the landing. A miniature chemical analysis lab using an alpha particle backscatter device was used to determine the lunar surface soil consisted of basaltic rock.
