On October 7, 1959, the television system obtained a series of photographs that were developed on-board the spacecraft. The photographs were scanned and were radio transmitted to ground stations in facsimile form on October 18, 1959, as the spacecraft, in a barycentric orbit, returned near to the Earth. The photographs were to be retransmitted at another point close to Earth but were not. The spacecraft returned very indistinct pictures, but, through computer enhancement, a tentative atlas of the lunar farside was produced.
The purpose of this experiment was to obtain photographs of the lunar surface as the spacecraft flew by the moon. It was particularly desirable to get photographs of parts of the moon not seen well or never seen from the earth, such as the limb and farside of the moon, to gain knowledge of the characteristics of the unseen hemisphere of the moon.
