Although the majority of the Zond flights were oriented toward gathering information about the techniques and technologies needed to get astronauts to the Moon and back safely, they did collect other information of scientific interest. Instrumentation flown on these missions gathered data on micrometeor flux, solar and cosmic rays, magnetic fields, radio emissions, and solar wind. Biological payloads were also flown and many photographs were taken.
