Kosmos 463

 1971-107A

---

Kosmos-463 was launched by 11A57 from Baykonur into a 65 degree orbit. The Zenit-4M satellite was recovered after only 5 days. This was the shortest Zenit-4M mission, but several others would have similar short durations. It isn't know whether these short missions were planned that way, or whether the capsules were recovered early for technical problems or to return urgent data.
