The next 3MV launch was a new Mars flyby variant, 3MV-4 No. 2 (or 3MV-4A No. 2?), the first 3MV aimed towards Mars. It was named Zond-2 once on an interplanetary trajectory. Zond-2 suffered a partial power failure after orbit insertion (a solar panel failed to deploy). It transmitted until May 1965. The probe flew 1500 km from Mars in Aug 1965.
