On August 11, 1969, the spacecraft flew past the Moon at a distance of 1984.6 km and conducted two picture taking sessions.

On its way back from the Moon the spacecraft tested its radio systems by transmitting recorded voices.

The phantom was equipped with 20 channels for radiation detectors (thermoluminescent glasses and nuclear photoemulsions) distributed along the whole body for measurement of doses in critical organs.

The doses accumulated during the flight through the radiation belts and around the Moon were between 0.2 and 0.7 rad in different points at the depth of 3 g/cm2 from the body surface.

Zond 7 reentered Earth's atmosphere on August 14, 1969, and achieved a soft landing in a preset region south of Kustanai, Kazakhstan.
