The payload emitted a non-conforming signal to the onboard computer, which interpreted this as a shift in direction. The second ignition of the D Block was thus performed with a faulty inclination, leading to the failure of the mission.
Since Next Spaceflight focuses solely on space launchers, this flight is counted as a success, as the failure came from the payload.

Mission Details
Cosmos 305
The Ye-8-5 is a version of the Ye-8 to drill a small sample of lunar soil and return it to earth. This could be launched in coordination with the L3S. Although not a manned lunar landing, it would provide a Soviet crew in orbit around the moon, and return of lunar soil to earth, nearly matching the Apollo mission.
