Kosmos 27

  1964-014A

---

3MV-1 No. 3 was to test new systems for space probes and was to be launched toward Venus. It reached Earth orbit and the Blok-I third stage separated but the fourth stage control system failed. 3MV-1 No. 3 was given the cover name Kosmos-27; it would have been Zond-1 if successful. The USSR reported that Kosmos-27 `required only one orbit to complete its flight plan'.
